The Iranian Neurological Association is pleased to have the opportunity to host this conference and to welcome participants from different cities of Iran and around the world to this exciting and stimulating event which will bring together colleagues from around the world to discuss topical issues in different the field of neurology. We will discuss the major breakthroughs and developments in the field of neurology – from clinical practice to research and technology. In addition to a top-rate scientific program, there will be many opportunities for hands-on learning and networking as well as exciting social events. Our Annual Congress is a unique occasion for members of the society and the community to gather and work together toward our common goals i.e., improvement of our knowledge and patients’ health. We are eager to participate and discuss exciting new findings, technologies, and opportunities in this field I am sure will leave a lasting impression on us all. We look forward to opening our doors to everyone to Iran for 22nd Annual Conference 2015. Sincerely Yours, Professor Hossein Pakdaman President of Iranian Neurological Association 6 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 Dear All After announcement for the submission of abstracts for the 22nd Iran neurology congress on November 2014, up to its deadline on March 2015, we have received more than 164 abstracts in several topics of neurology and neuroscience fields. As an innovation and for the first time in Iran we decided to prepare an E-book abstract panel in the congress website. The advantages of this E-book are: global availability, ability of rapid updating, searching capability, including the late breaking articles and lack of paper overuse. We aim that the E-book will be accessible on the congress website at least for 6 month then to be archived in the website of Iranian Neurological association for the later periods. On behalf of the scientific committee of the 22nd congress, I acknowledge the efforts of all of my colleagues in both aspects of the scientific and executive processes. S.M.Nabavi, MD Congress Chairman 7 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 ORAL PRESNETATIONS 8 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 100 Motor Neuron Disease: Introduction and Diagnosis Farzad Fatehi Iranian Center of Neurological Research, Shariati Hospital, Tehran University of Medical Sciences, Tehran, Iran Amyotrophic lateral sclerosis or a more general term, motor neuron disorder, are a group of disorders pathologically characterized by the destruction of motor neurons centrally, peripherally or in both sites in most of the cases. In a great majority of the patients, it behaves as a grave progressive disorder primarily manifested as weakness of limbs with ensuing weakness of bulbar muscles and respiratory muscles. The earliest symptoms of ALS are typically obvious weakness and/or muscle atrophy. Other presenting symptoms comprise trouble cramping, swallowing, or stiffness of affected muscles; muscle weakness affecting an arm or a leg; and/or slurred and nasal speech. The parts of the body affected by early symptoms of ALS depend on which motor neurons in the body are damaged first. Usually the patients with long standing pure upper motor symptoms (such as primary lateral sclerosis) or pure lower motor neuron disorder (progressive muscular atrophy) demonstrate better prognosis. Usually the eye motor muscles are intact; however, People with ALS may have difficulty in making voluntary fast movements of the eye. In addition, sphincter problems are rare or seen in late stages. Cognitive problems are usually late findings in these patients; however, in some forms with genetic mutations in TDP43 or C9ORF72, cognitive disorders such as frontotemporal lobe dementia are an early finding. 9 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 101 ALS mimic syndromes Majid Ghasemi Isfahan University of Medical Sciences, Isfahan, Iran The term amyotrophic lateral sclerosis (ALS) mimic syndrome has been used to describe a diverse group of conditions, the presentation and clinical features of which may resemble those of ALS at the outset. Many diseases, both neurologic and systemic, may mimic ALS, making the differential diagnosis rather extensive. Incorrect diagnosis of ALS is a significant problem with more misdiagnoses occurring in patients over 60 years. Several studies over the past decade have collected data indicating that rates of misdiagnosis in the general medical population are high. The more common misdiagnosis is falsenegative diagnosis when the patient with ALS is told that he/she has another disease. A false-negative rate of 43% has been reported from New Jersey and of 40% from Turin, Italy. In a recent E-mail survey of ALS patients throughout the US, 27% indicated at least one prior misdiagnosis. False-positive diagnosis may also be a problem in which the patient is mistakenly told that he/she has ALS. A survey in Scotland indicated that at least 8% of those initially labeled as having motor neuron disease were later found to have other neurologic diagnoses. In patients diagnosed with ALS the absence of disease progression, the presence of an atypical history, the presence of unusual symptoms should trigger a search for ‘mimic syndromes’. One may approach the differential diagnosis in terms of anatomy, symptoms, clinical presentation. For this discussion, we discuss the differential in terms of nervous system anatomy. 10 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 102 ALS Management: New research highlights Davood Fathi Tehran, Iran Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disorder of the motor system, with an annual incidence of 2/100000 and a prevalence of 5-7/100000. ALS is the commonest form of a group of disorders called motor neuron diseases which includes classical sporadic ALS, progressive bulbar palsy, progressive muscular atrophy, and primary lateral sclerosis. ALS is clinically manifested by progressive muscular weakness and atrophy, with a combination of upper and lower motor neuron signs caused by degeneration of motor neurons in the motor cortex, brain stem, and anterior horn of the spinal cord. Electrophysiological assessment is used in patients with suspected ALS for two reasons, first: to support the diagnosis by finding evidence of a more widespread motor neuron dysfunction than is apparent clinically and second: to exclude other ALS-mimicking syndromes. There have been proposed several sets of criteria to facilitate an earlier diagnosis of ALS which combine the clinical and electrophysiological assessments. The latest consensus criteria for diagnosis of ALS which determines the best use of electrophysiological findings is Awaji-shima criteria which has been proposed by a group of international experts in Awaji-shima, Japan in 2006. In Awaji-shima criteria electrophysiological and clinical signs of lower motor neuron have the same value in the decision of lower motor neuron involvement in patients. According to this new definition, clinically probable laboratory supported ALS, which was used in revised El Escorial criteria has been deleted in Awaji criteria. Another difference in the Awaji-shima criteria in comparison to the revised El Escorial criteria is that the fasciculation potentials in electrophysiological study are equivalent to fibrillations and positive sharp waves as evidence of acute denervation. According to the Awaji criteria, clinically definite ALS is defined by the presence of clinical or electrophysiological evidence of both lower motor neuron and upper motor neuron involvement in bulbar region and two spinal regions or in three spinal regions. Clinically probable ALS is defined by the presence of clinical or electrophysiological evidence of both lower motor neuron and upper motor neuron signs in at least two regions with some upper motor neuron signs necessarily rostral to the lower motor neuron signs. Clinically possible ALS is defined by the presence of clinical or electrophysiological evidence of both lower motor neuron and upper motor neuron signs in only one region; or upper motor neuron signs are found alone in two or more regions; or lower motor neuron signs are found rostral to upper motor signs. ALSmimicking syndromes must be ruled out by neuroimaging or other laboratory tests. 11 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 103 Electrophysiologic assessment and diagnosis of ALS Mohammad Yazdchi1, Haleh Mikaeili2 Neuroscience Research Center, Tabriz University of Medical Sciences, Tabriz, Iran Tuberculosis and Lung Disease Research Center, Tabriz University of Medical Sciences, Tabriz, Iran Symptom-based management of amyotrophic lateral sclerosis Multidisciplinary ALS clinics provide care from neurologists, physical therapists, occupational therapists, speech therapists, respiratory therapists, dietitians, social workers, and nursing care managers. Thus, specialized clinics can guide the management of the complex issues related to ALS, which include respiratory symptoms, nutrition, dysarthria, dysphagia, functional decline, and psychosocial problems. Current American and European guidelines state that specialized multidisciplinary clinic referral should be considered for patients with ALS, with the goals of optimizing health care delivery, prolonging survival, and enhancing quality of life. RESPIRATORY MANAGEMENT - Important aspects of pulmonary care include counseling the patient and family about potential treatments, the use of pulmonary tests to assess respiratory function, and the utility of noninvasive and invasive ventilation. DYSPHAGIA AND NUTRITION — In patients with ALS, limited data suggest that percutaneous gastrostomy tube (PEG) placement is associated with prolonged survival, although the degree of survival advantage is uncertain. In addition, nutritional supplementation using PEG may be helpful for stabilizing weight loss common in ALS. SYMPTOM MANAGEMENT — Among the prominent symptoms of ALS addressed by national guidelines are dyspnea, muscle spasm, spasticity, sialorrhea, and pseudobulbar affect. Equally important and potentially debilitating are other problems associated with ALS. These include dysarthria, muscle weakness, functional decline, loss of ambulation, pain, sleep problems, and psychosocial issues such as depression. Dysarthria — Speech therapy is rarely helpful; however, communication disorders specialists are important resources to help with choosing appropriate alternative communication methods. These methods may include writing with pen and paper or alphabet boards. Electronic communication devices have been extensively developed in recent years, and they can be adapted for use with either hand or eye controls. Dyspnea — Trunk elevation, chest physiotherapy, and reassurance may be helpful. For intermittent dyspnea, inhaled opiates such as morphine 5 mg may be helpful. If intermittent dyspnea is severe, intravenous midazolam can be given slowly up to 5 to 10 mg. For anxiety, lorazepam 0.5 to 2 mg sublingual can be useful. Fatigue — Fatigue is occasionally associated with riluzole treatment, but more commonly is a manifestation of the effort required to perform daily activities. For debilitating fatigue, modafinil is sometimes helpful. Withdrawal of riluzole may be considered in patients with debilitating fatigue. Muscle spasms — Quinine sulfate 325 mg twice a day was considered the most effective treatment option for muscle cramps. Other medications tried for cramps include baclofen, gabapentin, and tizanidine. Muscle weakness and functional decline — Assistive devices such as canes, ankle foot orthoses, crutches, and walking frames can be helpful early in the course of the disease. Most patients will eventually require a wheelchair.Higher toilet seats and bathtub lifts help to maintain toileting and bathing independence. Sialorrhea — Drooling is a common symptom in ALS. It is caused by the combination of facial muscle weakness and reduced swallowing ability. Sialorrhea can be treated with Atropine, Amitriptyline, Glycopyrrolate, Botulinum toxin injection into the salivary glands. Pseudobulbar affect — The combination drug dextromethorphan-quinidine, Amitriptyline, Fluvoxamine have been shown to be effective in controlled studies. Psychosocial aspects — As examples, a questionnaire study of 25 patients with ALS found that about 44 percent reported depression. Observational data suggest that treatment of depression can improve quality of life in ALS, even in physically debilitated patients. Disease modifying treatment of amyotrophic lateral sclerosis: RILUZOLE — Riluzole is the only drug to have any impact on survival in ALS. The evidence that riluzole is beneficial comes from clinical trials. Riluzole 50 mg twice daily is recommended for patients with ALS. 12 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 Three separate mechanisms of riluzole are thought to reduce glutamate-induced excitotoxicity: inhibition of glutamic acid release, noncompetitive block of NMDA receptor mediated responses, and direct action on the voltage-dependent sodium channel. Riluzole is well tolerated, with the most significant adverse effects being gastrointestinal and hepatic. Neutropenia is extremely rare. The most common adverse effects of riluzole are asthenia, dizziness, gastrointestinal disorders, and elevations in liver enzyme activities. Liver function tests are indicated monthly for the first three months of riluzole treatment and every three months thereafter. EXPERIMENTAL THERAPY — The following illustrates the range of findings in some of studies: Clinical trials have found no benefit for celecoxib, ciliary neurotrophic factor, gabapentin, lamotrigine, lithium, talampanel, topiramate, valproic acid, verapamil, or minocycline. A phase II randomized controlled trial of 185 patients with ALS showed that the free radical scavenger coenzyme Q10, at up to 2700 mg daily, was safe. However, the trial investigators concluded that coenzyme Q10 treatment was futile and should not be further tested as a possible treatment for ALS. Two preliminary human clinical trials employing recombinant insulin-like growth factor type I (IGF-I) for ALS reported somewhat discrepant results. A third multicenter placebo-controlled trial of 330 patients with ALS found no evidence of benefit for IGF-1 on any of the primary or secondary outcome measures at two years. Animal models — Several animal models have been developed to investigate the pathogenesis and treatment of ALS. Earlier studies used pure motor neurons cultured in vitro. In vitro models of cell death based on superoxide dismutase (SOD1) dysfunction were developed after the discovery of the Cu/Zn SOD1 gene abnormalities in familial ALS, and several mouse and rat models expressing mutant forms of SOD1 exist. In addition, transgenic rodent models of ALS were developed based upon mutant forms of human TDP-43. The experimentally induced mutations G93A, G37R, and G85R in the transgenic mouse models have phenotypes similar to human ALS. There are also naturally occurring mouse models including the motor neuron degeneration (Mnd), progressive motor neuropathy (pmn), and wobbler. Neurotrophic factors — Trials utilizing insulin-like growth factor-I (IGF-I) and other neurotrophic factors for ALS have been unsuccessful. Antioxidants — Oxidative stress has been implicated in the pathogenesis of ALS due to the production of oxygen free radicals resulting in lipid peroxidation, cytoskeletal disruption, and damage to the mitochondria. At least two randomized controlled trials have failed to demonstrate significant benefit of vitamin E as add-on therapy to riluzole in ALS. Bioenergetic agents — The energy buffering agent creatine has been studied as a way to prevent or mitigate mitochondrial dysfunction. In transgenic mouse model data, oral administration of creatine showed dose-dependent benefit, with 1 percent creatine extending survival by 13 days and 2 percent creatine by 26 days. This benefit seen with 2 percent creatine surpassed the extended survival seen with riluzole in this mouse model. Despite the promise of creatine in animal models, human randomized controlled trials failed to demonstrate efficacy for creatine at doses up to 10 grams/day in the treatment of ALS. Antiapoptotic agents — A tricyclic selegiline analog, TCH346 (also called CGP3466) interacts with glyceraldehyde-3-phosphate dehydrogenase (GAPDH) in a mechanism that may prevent programmed cell death. It reduces the degeneration of motor neurons in many in vitro models of apoptosis, but it did not have significant effects on survival in transgenic mice. Current and future trials — A number of agents are under active investigation for the treatment of ALS, including the following: Antisense oligonucleotide therapy for SOD1-associated familial ALS, Arimoclomol for familial ALS, Ceftriaxone, Creatine, Dexpramipexole, Memantine, NP001, Stem cell treatments, Tamoxifen Heart drug may help treat ALS, mouse study shows Digoxin, a medication used in the treatment of heart failure, may be adaptable for the treatment of amyotrophic lateral sclerosis (ALS), in a new study conducted in cell cultures and in mice, scientists showed that when they reduced the activity of an enzyme or limited cells’ ability to make copies of the enzyme, the disease’s destruction of nerve cells stopped. The enzyme maintains the proper balance of sodium and potassium in cells. Bonni’s results suggest the sodium-potassium ATPase plays a key role. When he conducted the same experiment but blocked the enzyme in ALS astrocytes using digoxin, the normal motor nerve cells survived. Digoxin blocks the ability of sodium-potassium ATPase to eject sodium and bring in potassium. 13 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 104 Chronic Migraine: Definition & Treatment Hassan Paknejad Neurology department, Alborz University of Medical Sciences, Karaj, Iran Globally, the top three causes of consultation for headache, in both primary and specialist care, are migraine, tension-type headache and the combination of these (WHO headache atlas, 2011). Tension-type headache is the more prevalent disorder worldwide, but consultation frequencies overall for migraine and tension-type headache only partially reflect this difference. Migraine is associated with a higher probability (per person affected) than tension-type headache of consultation for head ache, and more so in specialist than in primary care. Primary-care physicians, almost universally, are consulted more often for tension-type headache, which almost certainly reflects its greater prevalence. Specialists on the other hand see more migraine, probably a reflection of its relative severity (greater individual burden). Chronic migraine is defined as Headache occurring on 15 or more days per month for more than 3 months, which has the features of migraine headache on at least 8 days per month (IHS III). It can be sometimes interchangeably missed with Medication-over use headache (MOH). Around 50% of patients apparently with chronic migraine revert to an episodic migraine subtype after drug withdrawal; such patients are in a sense wrongly diagnosed as chronic migraine. Equally, many patients apparently overusing medication do not improve after drug withdrawal, and the diagnosis of Medication-overuse headache may in a sense be inappropriate (assuming that chronicity induced by drug overuse is always reversible). Also, we should notice "CHRONIFICATION" in the field of headache, as a new term using recently in different pain disorders, which has special risk factors, predisposing factors, special treatment discipline. 14 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 105 Neuroimaging in Headache: Where, When and How Seyed Ehsan Mohammadianinejad Neurology Department, Ahvaz Jundishapur University of Medical Sciences, Ahvaz, Iran Since headache is the most common presenting complaint in outpatient clinics, the routine order of imaging is not cost effective and logical. There is also the concern of missing an important cause even in a very small number of patients with typical primary headache disorder. Considering ‘Red Flags’ as the basis for this decision is helpful. Chronic daily and new daily persistent headaches are among the red flags which mandate neuroimaging until we are certain that the problem is a primary benign headache. In adult patients with typical migraine according to IHS criteria, the routine use of neuroimaging is NOT warranted. However the final decision to image is left to the physician on a case-by-case basis. The presence of atypical features may raise the suspicion of a secondary cause for an apparently primary migraine headache which is then called as secondary migraine headache. It is very important to consider the best imaging modality according to an oriented and precise history and clinical examination. The request of a standard brain MRI or CT may easily miss a serious cause of headache which may be detectable by other imaging modalities. MR Angiography should be part of evaluation of any patient with thunderclap headache, family history of aneurysm and continuously ipsilateral or progressing headache suggesting extracranial artery dissection. Early diagnosis of cervical artery dissection is possible based on timely ordering angiography in any patient with unexplained progressive unilateral head and or neck pain. In pregnancy MRI is preferred but contrast should be avoided because there is concern of a serious complication called as nephrogenic systemic fibrosis in the fetus. Use of MRI with contrast, though has limitations, should be regarded in selected conditions where it provides diagnostic clues Incidental findings are structural abnormalities or anatomic variants that are unexpectedly discovered during a neuroimaging study in patients with headache but are unrelated to the complaint. They are rarely if ever the cause of headache except when the cysts are so large to produce mass effect or obstructive hydrocephalus or when venous anomalies or telangiectasias are associated with other vascular malformations such as cavernous angioma with hemorrhage. So correct interpretation and discussion with the patient is important to lessen the anxiety and to avoid unnecessary additional diagnostic procedures. 15 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 106 Myasthenia Gravis Update Mohammad Kian Salajegheh Department of Neurology, Brigham and Women’s Hospital, Harvard Medical School, Boston, Massachusetts, USA Neuromuscular junction (NMJ) disorders are a group of neuromuscular diseases that present with pure motor weakness that may fluctuate from time to time, and worsen with certain triggers. Myasthenia gravis, the most common disease within this group, is due to immune attack against the NMJ, most commonly the acetylcholine receptors (AChR). It usually presents with ocular, bulbar and proximal more than distal extremity muscle weakness that worsens with prolonged use. Diagnosis is made by identifying the characteristic pattern and demonstrating abnormalities on confirmatory testing. These include decremental response on slow repetitive nerve stimulation (RNS), the presence of blocking, or abnormal jitter, on singe fiber EMG (SFEMG) as well as identification of serum antibodies against NMJ components. Treatment includes the use of choline esterase inhibitors (CEI), as well as prednisone and other immunosuppressive, with more recent and targeted studies being explored through multi-centric studies. 16 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 107 Visual Rehabilitation in Neurology Behzad Mansouri Section of Neurology, Department of Internal Medicine, University of Manitoba, Winnipeg, Manitoba, Canada Stroke rehabilitation is the current standard of care in many developed countries. Though highly commonplace now, the restoration of neural circuits through perceptual training and motor exercise is a relatively new practice. The mechanism of stroke was first described in 19th century though stroke rehabilitation was introduced to medicine in mid 20th century. Before the 1950’s, stroke patients were instructed to rest and hope for spontaneous partial recovery of function. The shift to strenuous repetitive training as a therapeutic approach was arduous and slow to take hold. It was decades before rehabilitation became the standard of care. Partial cortical blindness and other visual deficits affect a large portion of stroke and traumatic brain injury (TBI) patients, which severely lowers quality of life. Today’s approach to visual deficit is comparable to that of the pre-stroke rehabilitation of motor function era. There is no standard therapeutic intervention for visual rehabilitation. Patients are simply instructed to wait and hope for spontaneous recovery. Over the last two decades, there has been speculation of the plasticity of the visual system and how it pertains to the potential for recovery of function. There have been many attempts in developing medical equipments to expand the visual field and increase the patients’ visual confidence and quality of life. The mechanism of visual expansion is hotly debated due to inaccuracies of eye fixation and artifact control. However, it can be argued that visual rehabilitation holds clinical value due to consistent patient satisfaction after intervention. Visual plasticity and perceptual learning have been investigated extensively in the last two decades. However, visual rehabilitation development is in its infancy. More research is needed to study the effect of multi-sensory visual rehabilitation and its use in combination with other therapeutic methods such as transcranial electrical or magnetic brain stimulation. Restoration visual rehabilitation should be used as a complement to compensatory training i.e. frequent saccadic eye movement, and use of prisms to expand the spared visual field, in order to provide an all-encompassing rehabilitation of visual function. It can be expected that in time, visual rehabilitation will become the new standard of care within a multidisciplinary setting. 17 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 108 An overview of PML in MS disease modifying Vosughi R Health Sciences Centre, Winnipeg, Manitoba, Canada “Treating Multiple Sclerosis is becoming more and more challenging for the neurologists. Although having multiple therapeutic choices certainly add to complexity of treatment, serious and sometimes life threatening side effects of disease modifying drugs (DMDs) make it harder to balance the benefit of treatment options against their harms. In this presentation, we review available literature about Progressive Multifocal Leukoencephalopathy (PML) related to MS therapeutics: its risk with different DMDs, risk stratification, approach and treatment.” 18 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 109 An Update on Proton MR Spectroscopy of Brain Zamani AA Department of Radiology, Brigham and Women's Hospital, Boston, MA 02115, USA Thirty years after introduction of clinical MRI into the practice of radiology, MR spectroscopy has evolved from a research tool into a clinical imaging modality. Many centers now incorporate MRS with clinical MRI in evaluation of a wide range of neurological diseases. With widespread use of 3T MR unit MRS has received a new boost. With availability of 7T and 9.4T magnets in a few centers, MRS promises to allow detection of many more metabolites and hopefully, assist in clinical decision making. ADVANTAGES OF 3T over 1.5T: There is increased signal to noise ratio. There is also more chemical shift with 3T therefore allowing better separation of metabolites. This has allowed separation of glutamine from glutamate and identification of GABA. Measuring Glutamate/ glutamine has allowed investigators to study the glutamate/ glutamine in superior temporal lobe of schizophrenic patients. Being able to identify GABA, a neurotransmitter has opened the door into investigation of many disorders including psychiatric disorders. Identification of additional metabolites: Besides the usual metabolites (NAA, choline, creatine, myoinositol, glutamate/glutamine and lactate), MRS is able to detect other metabolites such as alanine in menigiomas, taurine in PNET and glycine in high -grade pediatric tumors. Deelchand et al report identification of 19 metabolites with 9.4 T. Detection of 2HG in gliomas is an important finding that is helpful both in diagnosing and also in prognostication. Isocitrate dehydrogenase enzyme exists in the cytoplasm (IDH 1) and in the mitochondria (IDH2) and converts isocitrate to alpha-ketoglutarate. Recent studies have shown that the genes that encode this enzyme can undergo mutations in 68-86% of grade II and III gliomas, as well as in some secondary GBMs. This mutation causes accumulation of 2 -hydroxyglutarate (2HG) in cells. Detection of this compound is difficult as the peak due to 2HG overlaps the peaks for glutamate and glutamine, normally abundant metabolites. Investigators, however, have found a way of achieving this. At our institution, an echo time of 97 msec is used to optimize visualization of this peak. Patients with IDH1 mutation have a better 5-year survival compared with those that do not. Therefore detection of this mutation via spectroscopy may have prognostic value. On the other hand such a mutation is relatively common so detection of 2HG via MRS is used as a differential diagnosis point in favor of diagnosis of gliomas as this mutation is not seen in other entities. It is hoped that in the future other metabolites will be found that will have similar diagnostic and prognostic value in other brain tumors. MRS IN METABOLIC DISEASES: Inborn error of metabolism lends itself to MRS investigations. Examples of this include increased NAA in Canavan disease and absence of creatine in guanidinoacetae methyl transferase deficiency. In ornithine transcarbamylase deficiency, an enzyme in urea cycle, hyperammonemia is seen. Ammonia is changed into glutamine in the liver. Glutamine can be detected with MR spectroscopy. With proper treatment this peak will decrease and therefore, the course of the disease and success of treatment can be monitored with MRS. MRS IN NOTHER ENTITIES: In perinatal hypoxia-ischemia quantitative measurement of lactate is an early sign of brain injury. If the lactate remains high persistently, it is an indication of poor prognosis. With widespread use of DWI in early detection of acute infarction, MRS does not have an important role in these entities. Diagnosing tumefactive MS with MRS is difficult as the MRS picture is not distinguishable from that of a neoplasm. PROBLEMS WITH MRS: Despite its availability over thirty years, MRS is considered an “investigational tool” by many insurance companies and government agencies. This leads to lack of reimbursement and underuse. The problem has its root in lack of standardization and lack of a consistent methodology and interpretation. The choice of technique is a problem for the inexperienced imager. Each one of the techniques (single voxel, vs. chemical imaging vs. whole head volume imaging) had its own advantages and disadvantages. The American college of Radiology has created a set of guidelines to help with this choice and to ensure diagnostic studies are generated. The individual imagers using spectroscopy should discourage the referring physicians from ordering spectroscopy if MRS is doomed to failure. Most importantly, MRS does not work if the lesion is too small and if it is near the skull base, sinuses, etc. 19 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 110 Transition of Epilepsy from Children to Adults: Definition, Epidemiologic and Social Aspects and Models of Transition Clinic Jafar Mehvari Isfahan Neurosciences Research Center, Isfahan, Iran Definition: Overall 50% of children with epilepsy will become adults with epilepsy, which may last for their entire Lives. Pediatric epilepsy syndromes and their treatment involve special concerns.The issue of transfer/transition for children with chronic disease to adult medical care is receiving increasing attention as more children with chronic diseases survive to adulthood and require special lifelong treatment.Although the terms “transfer” and “transition” are often used interchangeably, they have very different connotations.Transition is a process to prepare youth for adult health care.It involves learning about the diseaseand its manifestations, about medications and how to handle them, when and how to seek help, and how to manage problems to minimize the effect on normal adult life.Transfer is the formal handing over of care from pediatric to adult health care providers. Three broad groupings of patients with epilepsy will achieve transition/transfer. The first group has epilepsy that begins early in life and persists. Many of these patients have concomitant intellectual disability and complex causes for their disorders, particularly genetic. These young adults with epilepsy have little expectation for independent living and will require various degrees of supervision. The second group of patients develop epilepsy in adolescence, with a small likelihood of remission. Focal epilepsies and juvenile myoclonic epilepsies predominate, and intellectual function is typically normal. A third group of patients are children with epilepsy whose seizures remit completely in childhood, and yet are left with comorbidities. Examples are childhood absence epilepsy, “benign” rolandic epilepsy, or nonlesional focal epilepsy. Unlike the other two groups, these patients may not require expert epilepsy care because their epilepsy is rarely active in adulthood. Epidemiologic aspects: In the Finnish population-based cohort of patients with childhood-onset epilepsy followed for 37 years on average, approximately 33% of cases had seizures during adulthood and 19% never experienced remission. Similar observations were made in the Nova Scotia population-based cohort, represented by children and adolescents with epilepsy followed for to 30 years.In this cohort, 25% of patients with idiopathic Generalized epilepsies with tonic–clonic seizures did not attain seizure remission.Among patients with CAE, 35% were not in remission at last follow-up.Fifteen percentof the total childhood absence cohort had progressed to juvenile myoclonic epilepsy (JME).Factors predicting no remission included cognitive difficulties at diagnosis absence status prior to or during AED treatment, development of generalized tonic–clonic or myoclonic seizures after onset of AEDs, abnormal background on initial electroencephalography (EEG), and family history of generalized seizures in first-degree relatives.For those with JME followed for >20 years, all seizure types had remitted in 17%, and myoclonic seizures persisted in only 13%.15 All children with BECTS followed for 30 years after diagnosis experienced terminal remission.Intellectually normal children with focal epilepsies not fitting into specific syndromic categories from the same cohort were also followed for 25–30 years.43% of the partial complex group was not in remission versus 19% of the secondary generalization group. The partial complex group was more likely to be intractable or to have undergone epilepsy surgery. There have been several clinical factors identified as predictors of no remission. The most consistent are associated neurologic deficits, intellectual disability, initial high seizure frequency with poor response to the first AED, onset at age <1 year or older than 10–12 years, and “remote symptomatic etiology.” A “causative” lesion on magnetic resonance imaging (MRI) also predicts failure of remission, although it is not absolute and may still be associated with remission. Combinations of risk factors may improve prediction. The majority of patients with idiopathic generalized epilepsies also had an adverse social outcome, which included the following: psychiatric diagnosis (27%), no high school graduation (40%), pregnancy outside stable relationship (38%), living alone (23%), unemployment (33%), or criminal conviction. It was found that adverse outcomes were also significantly more common in patients with partial complex seizures. During follow-up, >50% of patients had difficult-to-control seizures and learning and psychiatric/social problems.For those with BECTS, however, the social outcome was similar to the general population. Approximately 20% of childhood epilepsy is associated with intellectual disability noted during a child’s early, development. Cognitive impairment may also reflect effects of antiepileptic drugs.30 Individual AEDs exhibit different cognitive profiles. The death risk in epilepsy is 20 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 inversely correlated to the age at seizure onset, associate neuro-disability or underlying brain condition, to sudden unexplained death. Models for transition clinics: Models of care for transition and transfer vary around the world, with no objective way to indicate which approach is most effective. One transition/transfer model will not suit all contexts. Specialist emphasize a few basic concepts that should facilitate transition and a successful transfer to avoid a gap between pediatric and adult care. To develop transition program, the first step is identification of adult neurologists and epileptologists who are willing to care for these special patients. Joint pediatric/adult transition clinics may be the most effective system Canada: Most transition/transfer consists only of a referral letter written by the pediatric neurologist to an adult Epileptologist. The patient is then seen in the adult setting without further communication. The adult Epileptologist communicates with the family physician and may, out of courtesy, send a copy of this note to the pediatric neurologist. Further follow-up by the adult Epileptologist/ neurologist often depends on the patient being referred back by the family physician. This traditional transfer system hasshortcomings. Prior to transfer, the patient and family need to understand clearly when a reassessment is warranted. Transition in France: The model involved a single, dedicated adult neurologist who was assigned to take over the follow-up as young people with severe epilepsy grew into adultsTransfer included a transfer summary from the pediatric epilepsy service plus complete access to all of the pediatric medical records. There is a sense that transfer should occur in early adolescence without waiting for complete or nearly complete seizure control.There is an attempt to create an adult multidisciplinary team for persons with multiple disabilities Transition in the United Kingdom: There are four options for the continuing management of a young person at this stage. First, to be discharged back to their general practitioner; second, to remain under the care of the pediatrician or pediatric neurologist; third, tobe referred to an adult physician or neurologist (neither of whom may have expertise in epilepsy care); and fourth, to be seen in a dedicated epilepsytransition service.The benefit of this final option is that this operates separately from a pediatric or adult clinic and can provide continuity of specialist epilepsy care that is not only adolescent-specific, but is able to address specific evolving adult is transition. Driving and Exercise: Driving: Evaluation of diagnosis, seizure control, comorbid neurologic disorders including attention-deficit/hyperactivity disorder (ADHD) and intellectual ability, as well as risk-taking behaviors needs to be considered when advice regarding driving is given. Information on local driving regulations and legal liability needs to be provided. Exercise: There is uncertainty if people with epilepsy are more sedentary than the rest of the population. Exercise rarely exacerbates seizures, and there is limited evidence that it may improve seizure control.Exercise often improves the comorbidities of anxiety and depression.Transition discussions can advocate exercise while offering some guidance about safer activities 21 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 111 Transition issues in benign epilepsies, monogenic epilepsies and neurocutaneous disorders Sanaz Ahmadi Karvigh Tehran University of Medical Sciences, Tehran, Iran There are many monogenic disorders associated with epilepsy that begin in childhood and persist into adult life and every day with developments in genetic assessments more and more of these disorders are introduced. Some of these patients will have well controlled isolated seizures and others may have other progressing comorbidities. These include psychiatric features, intellectual disability, migraine, movement disorders, musculoskeletal features such as spasticity and extrapyramidal features, and scoliosis. Specific genetic disorders may show different seizure patterns in adult life compared with childhood. In the transition clinic, a full reevaluation is essential when any patient with an epileptic encephalopathy transitions to adult care. The reason is that an etiologic diagnosis may never have been made, and the investigations have often been performed many years ago when the current modern techniques were not available. Understanding the genetic cause is likely to inform understanding of comorbidities, prognosis, genetic counseling and therapeutic choices. The group of genetic epileptic encephalopathies is expanding, with new genes being identified at a rapid rate. These often arise secondary to a de novo mutation in the patient and can have various prognoses. The best characterized adult phenotype is for Dravet syndrome. Seizures often continue into adult life, but the pattern changes from frequent episodes of status epilepticus to weekly or monthly brief convulsions in sleep. Movement disorders are associated with specific monogenic epilepsies and, in some instances, occur at an age that is different from when the seizures present. It is noteworthy that, obtaining a history of either paroxysmal exercise induced dyskinesia or paroxysmal kinesigenic choreoathetosis can be challenging and patients often modify their lifestyle to avoid attacks and do not discuss them. Therefore, it is essential that the physician specifically addresses these issues in the transition clinic in the reevaluation phase. On the other hand, in transition clinics more benign epileptic syndromes with normal anatomic imaging, neurologic examination, and intellectual ability may be encountered. Although the benign epilepsy of childhood with centrotemporal spikes (BECTS) and the majority (65%) of those with childhood absence epilepsy (CAE) are epilepsy syndromes that enters terminal remission before the general age of a planned transition of adolescents( 16 years), approximately 15% of patients with CAE who initially remit during their childhood years later develop juvenile myoclonic epilepsy (JME) as teenagers and less than 2% of patients with BECTS may have a more severe course associated with treatment difficulties prior to terminal remission, at times with a rare evolution to an epileptic encephalopathy. All the same, due to total remission and lack of significant future social and cognitive disabilities usually no transition plans need to be made for BECTS patients. In contrast, a significant minority of the nonlesional focal epilepsy in otherwise normal children (NLFN) (~35%) and most patients with JME continue to have active epilepsy into adulthood. The risk of relapse in NLFN is low once total remission has been achieved: <1% per year and usually occurs in those who had needed several AEDs to control the seizures (refractory epilepsy). In addition, some cognitive disorders are reported in several large case series in CEA and JME patients that include subtle cognitive deficits and linguistic difficulties, which are frequently complicated by ADHD or associated with affective/anxiety disorders. There appears to be a greater risk with longer illness duration and higher seizure frequency. More importantly, these CAE, JME, and NLFN transition patients are at risk of a number of significant adverse social outcomes that require ongoing advice and counseling. 22 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 112 New conception about pathogenesis of refractory and super-refractory status epilepticus Ghaffarpour M Iranian Center of Neurological Research, Imam Khomeini Hospital, Tehran, Iran Refractory status epilepticus (RES) is defined as recurrent seizure activity despite two appropriately selected and dosed antiepileptic drugs, including a benzodiazepine. In a prospective study (Novy J et al 2010), 23% of patients admitted to the hospital with status epilepticus (ES) were considered to have RSE and retrospective studies Suggested that 31%-43% of SE episodes become refractory. The term “SuperRefractory status epilepticus (S-RSE)” was first introduced in April 2011, and defined as continuous or recurrent seizures 24 hours or more following initiation of anesthetic agents; including cases in which seizure control is attained after induction of anesthesia but recurs on weaning the patient off the anesthetic agent. Approximately 9% of SE episodes fail treatment with first-line and second- line agents. The RSE and S-RSE are unique in that, refractory Seizures are more likely to develop as a result of acute brain injury rather than as a consequence of chronic epilepsy. RSE may also occur in previously healthy patients, in whom SE develops de novo without a clear precipitant, referred new- onset RSE or NORSE. It is important to understand how seizures become refractory. As status epilepticus continues, neuronal damage and pharmacoresistancy become apparent after 30 minutes. The latter may be explained by intensified "receptor trafficking” in which NMDA receptors at the cell surface increases and the number of GABA receptors decreases secondary to receptor internalization. Other mechanisms include: 1) Mitochondrial insufficiency, 2) Inflammatory processes, resulting in decreased integrity of blood brain barrier, 3) Higher K+ levels, 4) Changes in gene expression, particularly those that encode multidrug transporter proteins. P-glycoprotein (Pgp) was the first of these proteins, followed by multidrug resistance-associated proteins (MRPs) and breast cancer-resistance protein (BCRP), and 5) reverberating seizure activity between hippocampal and parahippocampal structures. In This lecture we will review further details about pathogenesis, treatment and outcomes of RSE and S-RSE. 23 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 113 Starting, Stopping and switching in treatment of MS S.M.Nabavi Neurology Department, Shahed University, Tehran, Iran Cell Therapy Center, Royan institute, Tehran, Iran In this teaching course we will review the possibilities of starting of disease modifying therapies in multiple sclerosis (MS) and clinically isolated syndrome (CIS). Also we will discuss the definitions and options of suboptimal response to therapy or treatment failure in MS. We will explain the different lines of therapy in MS and some considerations in the sequencing or switching of therapies. Finally we will try to explain the different scenario in stopping of MS drugs. 24 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 114 Isotope Scanning and Neurology Practice Arman Hassanzadeh-Rad Department of Nuclear Medicine, Research Center for Nuclear Medicine, Shariati Hospital, Tehran University of Medical Sciences, Tehran, Iran In Nuclear Medicine various procedures are used for assessment of neurological function. In SPECT/PET imaging, after injection of gamma-emitter or positron –emitter radiotracers, multiple projections are acquired and then processed with either Filter Back Projection or Iterative Reconstruction methods to provide functional transaxial, sagital and coronal slices as well as 3-D reconstructed format of brain. Planar imaging is also used for specific indications like CSF-imaging and Brain Death evaluation. One important clinical indication of nuclear medicine in neurology is evaluation of perfusion and metabolism in dementia, making a scintigraphic diagnosis of type and severity of dementia in equivocal cases as well as patients with Mild Cognitive Impairment and assessment of response to treatment. Post traumatic brain injury and its impact on brain perfusion can also be evaluated by brain perfusion imaging agents (e.g 99m-Tc-ECD, 99m-Tc-HMPAO). One example is finding hypoperfusion in orbitofrontal cortex in patients with post-trauma hyposmia/anosmia. Localization of epileptogenic foci in patients with refractory epilepsy is another aim of nuclear medicine imaging techniques, obtained by either ictal/interictal perfusion SPECT imaging, or interictal FDG-PET imaging. As a guide for thrombolytic therapy in acute cerebrovascular events, quantitative brain perfusion scan can aid in both decisionmaking and predicting patient’s outcome. CSF imaging for diagnosis and characterization of different types of hydrocephalus (communicating/non-communicating) and in particular, intraventricular obstruction from hemorrhage,tumor, aqueduct stenosis or communicating hydrocephalus of Normal Pressure Hydrocephalus can be quite informative, providing incremental information. Assessment of ventriculoperitoneal shunt patency and CSF leakage are other applications of nuclear medicine scintigraphy. By introduction of new imaging techniques and development of new radiotracers, clinical indications of nuclear medicine are emerging rapidly. One good example is Parkinson’s Disease evaluation and differentiation from other syndromes with tremor by PET-CT assessment of basal ganglia synaptic activity with18-F-FDOPA or SPECT-CT evaluation of dopamine transporter activity with 99m-TcTRODAT imaging agents. Nowadays, a lot of radiotracers and imaging techniques, used to be research tools, are becoming established parts of clinical applications of nuclear medicine in neurological disorders. 25 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 115 Surgical Management of Idiopathic Intracranial Hypertension Behzad Mansouri Section of Neurology, Department of Internal Medicine, University of Manitoba, Winnipeg, Manitoba, Canada The prevalence of Intracranial Hypertension (IIH) has increased in the past decade, following the obesity epidemic. A direct dose-relationship has been demonstrated between increasing BMI or weight gain (>515%) and an increased risk for IIH. IIH remains a diagnosis of exclusion and IIH-related visual loss and headache requires medical and surgical management. The medical management of IIH involves (A) investigating and treating the possible causes such as medications (e.g. steroid withdrawal, lithium, tetracyclines, and vitamin A analogs), Systemic conditions (e.g. obstructive sleep apnea, renal failure, coagulopathies, and anemia), (B) weight loss and (C) medications (e.g. Acetazolamide, Topiramate or Thiazides). If maximum medical management fails the patients require surgical intervention i.e. optic nerve sheet fenestration (ONSF) or ventriculo-lumbo/peritoneal shunting (VPS and LPS). The former (ONSF), is reserved for patients with predominantly visual symptoms. VPS or LPS are indicated in patients with mainly headache (with or without visual loss) though headaches should not be the sole indication for shunting. Stereotactic placement of programmable valve for VPS are preferred. Ultimately, the decision for which surgical procedure is best in IIH remains surgeon and institution dependent based upon the local surgical expertise and availability. 26 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 116 Blood pressure management in acute stroke Amiri F Iran University of medical Sciences, Tehran, Iran Introduction and Pathophysiology Blood pressure (BP) is largely a surrogate for cerebral perfusion pressure (CPP). During acute ischemic stroke, cerebral blood flow (CBF) is predominantly influenced by mean arterial pressure (MAP), as intracranial pressure changes are negligible. A number of other physiologic factors also influence CBF, including oxygen and carbon dioxide partial pressure, cerebral metabolism, temperature, and blood viscosity. CBF is kept relatively constant across a wide range of perfusion pressures by adjustments in the diameter of vessel resistance, in a process known as autoregulation. In healthy subjects, autoregulation is maintained over a range of CPP (50–150 mm Hg); however, when autoregulationis lost, the relationship between CPP and CBF becomes more linear. As a result of occlusion or severe stenosis, resistance to flow increases, and dilation of arterioles compensates by lowering resistance to flow in the downstream arterial bed. A complex series of events, many of which are mediated in part by nitric oxide, ensures CBF compensation for changes in MAP. One of the many effects of ischemia on brain tissue is the loss of autoregulation. In this setting, CBF changes directly with alteration in MAP, rendering ischemic brain vulnerable to minimal variation of the systemic BP. Furthermore, arteriolar tone and consequent changes in CBF are the result of change in the local physiologic milieu, manifested by changes in factors such as extracellular potassium concentration and sustained depolarization. The loss of autoregulation during cerebral ischemia has been extensively demonstrated both in humans1 and in nonhuman primates. PET and autoradiography shed light on the series of events that follow cerebral ischemia. In particular, in several species, including humans, several other compensatory mechanisms occur upon reduction of CBF, such as increase in cerebral blood volume, increase in oxygen extraction fraction, and decrease in oxygen consumption. A detailed description of these important phenomena is beyond the scope of this review. In brief, as CBF decreases within the cerebral tissue affected by ischemia, there are regional variations in the execution of these compensatory mechanisms, depending on degree of ischemia, duration of ischemia, degree of collateral circulation, and phylogenetic susceptibility to ischemia of a particular neuronal subpopulation. As a result of these events, the ischemic tissue is divided into a core and a penumbra. The core is considered to be tissue already severely damaged by ischemia and most likely destined to infarction. The penumbra is the ischemic area surrounding the core that has the potential for recovery upon restoration of normal CBF values. On the basis of these data, adequate levels of MAP play a critical role in the survival of the penumbral tissue. Although the evidence is ample to suggest benefit of MAP maintenance or its elevation during ischemia, it cannot be viewed independently of CBF. BP is a surrogate for CBF and represents a transmural pressure that is distributed throughout the vascular tree. Transmural pressure represents a potential negative influence on transmural rupture (cerebral hemorrhage) and net bulk flow across capillary beds, thereby worsening cerebral edema (Starling’s equation) and secondary organ injury to heart and lung. Currently it is unclear how to appropriately weigh the benefits and risks to measure optimal outcome. The benefits and risks are not constant but instead are interdependent on vessel diameter, transmural pressure, and possible transmural rupture. Recommendation 1. Prospective studies are needed to evaluate CBF via imaging and physiologic continuous monitoringafter BP manipulation during acute ischemia. Natural history of blood pressure in acute ischemic stroke In patients with ischemic stroke, as many as 60% of patients have a systolic blood pressure (SBP) greater than 160 mm Hg. This elevation can persist for hours to days. Although some portion of elevated BP might be due to a compensatory need to increase CBF, other factors such as stress, pain, discomfort, and intrinsic hypertension likely play a role as well. Despite the etiology, BP has a tendency to normalize over 24 to 48 hours. With regard to stroke subtype, evidence suggests that lacunar stroke may be associated with higher initial SBP16 than non-lacunar stroke. Consequently, lacunar stroke–associated BP may decrease over 24 hours to a greater degree than non-lacunar stroke. Most data regarding the association of initial BP on stroke outcome indicate a U-shaped curve. Patients with lower BP have worse outcome than those with higher BP. Still, those patients with SBP greater than 180 mm Hg seem to have worse outcome than those with BP in the 150 to 180 range. From the International Stroke Trial Registry, there was either a 3.8% or 17.9% increase in early mortality for every 10–mm Hg change above or below 150 27 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 mm Hg, respectively. Others have suggested that initial high BP predicts poor outcome only in combination with impaired consciousness. However, other data suggest that initial BP is not associated with mortality, but elevated BP over the ensuing 48 hours is associated with higher NIH Stroke Scale (NIHSS) score and greater mortality. Whether or not high BP is a marker of disease severity or a modifiable mediator with a direct mechanistic relationship to outcome is unclear. We propose that the likely explanation is a component of both. At one extreme, increased BP is a secondary response to cerebral ischemia. As the size and degree of ischemia increase, with individual variability, the BP may increase to support perfusion. However, this response is pathologic, and, like cardiac ventricular remodeling in response to chronic hypertension, this compensatory effort by the body can have pathologic consequences (heart failure or brain failure). The period and setting of brain ischemia are often confounded by other variables that may increase BP independently: anxiety, pain, fever, inflammation, tissue plasminogen activator (tPA)–mediated hemorrhage. Ultimately, clarity with regard to the role of BP rise in the setting of acute ischemia can be answered only with prospective, randomized interventions. Such trials would need to have consistent management strategies for enrolled patients. It should be noted that it is not clear whether systolic, diastolic, or mean arterial BP is superior for determining outcomes. Although this is unproven, higher spontaneous initial BP might maintain CBF for penumbral tissue. This elevation in BP places patients at an increased risk of hemorrhage, edema, and secondary organ injury. Increased systemic BP increases systemic vascular resistance, thereby increasing myocardial strain and oxygen demand. Increased resistance and myocardial strain can also lead to pulmonary edema, especially in the setting of any volume overload. The correlation of high BP and increased risk of intra cerebral hemorrhage is unknown. There was no association with BP and hemorrhage in the European Cooperative Acute Stroke Study (ECASS) I, International Stroke Trial, National Institute of Neurological Disorders and Stroke (NINDS), or Interventional Management of Stroke trials. However, elevated BP is associated with intracerebral hemorrhage after administration of tPA, streptokinase, or urokinase. Existing data support an increased risk of cerebral edema when there is simultaneous high BP. The excessive risk of patients presenting with lower BP is likely secondary to failure to maintain sufficient CBF for penumbral survival. Failure to maintain sufficient CBF is also coupled with higher occurrence of larger stroke, cardioembolic stroke, and heart failure. Recommendation 1. Prospective studies are needed to determine the association of BP and the risk of hemorrhage, cerebral edema, and secondary organ injury, which are based on stroke severity, neurologic deterioration, infarct volume, and other factors associated with poor outcome. Blood pressure management in the setting of thrombolytic and revascularization therapy In the NINDS recombinant tPA trial, there was a similar incidence of hypertension in the placebo recipients and tPA treated patients. Hypertensive patients treated with tPA who also received antihypertensive medications had a less favorable outcome at 3 months. In contrast, treatment with recombinant tPA in the NINDS trial was associated with greater BP reduction than placebo. Also, in patients treated with recombinant tPA, higher SBP was associated with persistent occlusion, as assessed by ultrasound, but without worse clinical outcomes at 3 months. Cause and effect cannot be inferred but supported the hypothesis that elevated BP is required to maintain penumbral flow. This evidence is supported by spontaneous reductions in BP after recanalization and increases in infarct volume in the setting of large BP fluctuations without recanalization. Furthermore, hemorrhagic transformation after thrombolytic therapy, consistent with recanalization and the potential for increased brain edema, was associated with a trend toward lower SBP. Conversely, in the setting of thrombolytic therapy, there is significant evidence supporting an association with elevated BP and intracerebral hemorrhage. Recommendations 1. In agreement with the 2007 American Stroke Association Guidelines, SBP should be kept under 180 mm Hg and diastolic BP (DBP) under 105 mm Hg in patients who have received thrombolytic or interventional therapy for the immediate postprocedure period. There are no data to suggest a particular antihypertensive medication to use when it is necessary to lower BP. However, medications that can be rapidly titrated are preferred. 2. Prospective CBF studies are needed to assess any relationship between arterial recanalization and BP that could account for differences in collateral circulation. 3. Prospective randomized trials for BP treatment after recanalization therapy, either drug thrombolysis or mechanical thrombectomy, are needed and should be stratified according to absence or presence of recanalization. 28 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 4. Prospective studies are needed to assess the natural history of BP in the setting of interventional therapies. These studies should examine the association of infarct volume, volume of at-risk tissue, collateral flow, recanalization flow, and location of vessel occlusion. Lowering BP in acute ischemic stroke Because of the direct relationship between CPP and MAP, lowering BP can diminish CBF to ischemic brain tissue. In a multivariate analysis, accounting for NIHSS score and stroke location, BP reduction in the first 24 hours was independently associated with poor outcome. A Cochrane database review of trials aimed at acute or subacute reduction of BP after ischemic stroke included 5 randomized trials and 218 patients. There was insufficient evidence to support lowering BP in patients with acute stroke. In fact, 3 randomized trials testing nimodipine or _-blockers, BEST, INWEST, and VENUS, all had worse outcomes in the active treatment group. Only interventions in BEST and INWEST were associated with BP lowering. More recently, a trial of candesartan administration within the first 36 hours of stroke (mean time from stroke onset to treatment _ 30 hours) compared to 7 days of placebo found no significant difference in BP decline and a significant improvement in mortality and recurrent stroke at 1 year. The lack of effect on BP reduction suggests a mechanism other than BP regulation for this protective effect. In another trial, hypertensive (SBP _140 mm Hg or DBP _90 mm Hg) ischemicstroke patients were randomized to oral lisinopril or placebo within 24 hours of stroke onset. These investigators found significant differences in BP reduction without any difference in clinical outcome. This trial was not powered for clinical outcome. It remains to be proven whether certain classes of antihypertensives might have beneficial effects on stroke outcomes regardless of BP changes. Recommendations 1. In agreement with the 2007 American Stroke Association Guidelines, for patients not receiving thrombolytic or interventional therapy, BP medication should be withheld for the first 24 hours unless SBP is above 220 mm Hg or DBP is above 110 mm Hg. 2. After 24 hours, BP medications may be restarted safely in a general stroke population, although there are limited high-level data to support this recommendation. 3. Prospective outcome studies are needed to evaluate early initiation of BP therapy in the setting of documented presence or absence of recanalization. 4. Studies are needed to determine whether hypertensive patients with persistent penumbra at 24 hours benefit from the withholding or institution of antihypertensive therapy. Induced hypertension Because of the desire to improve CBF to penumbral tissue, either through a flow-limiting lesion or through collateral circulation, several groups have attempted to induce hypertension in patients with acute ischemic stroke. For this purpose, _-adrenergic agonists are an attractive choice, as selective vasoconstriction of the peripheral arterial bed can be achieved without involvement of cerebral arteries. In another report, hypertension was prospectively induced in 13 patients within 12 hours of presentation. None of the patients had serious adverse events, and 54% had an improvement of at least 2 points on the NIHSS, attributable to the BP increase. In a retrospective report, ischemic stroke patients with SBP _140 mm Hg were treated with hypertensive therapy (average time of stroke onset to treatment _ 13 hours). Early improvement, defined as a 2-point decrease in NIHSS within 8 hours of therapy, was seen in 19% of patients. Treatment was associated with 1 cardiac arrhythmia and 1fatal intracerebral hemorrhage. Other studies of induced hypertension in the subacute phase, i.e., initiation within 7 days of stroke onset, in patients selected for diffusion–perfusion mismatch have had mixed results. The only trial that was randomized demonstrated a significant improvement in NIHSS score for induced hypertension. It is unclear whether these subacute trials of induced hypertension apply in the acute periprocedural time frame for endovascular treatment. Although there appears to be promise for induced hypertension in the acute phase, it is unclear how best to select patients who might benefit and whether a benefit of improved neurologic function will outweigh the potential complications of intracerebral hemorrhage, cerebral or pulmonary edema, and myocardial infarction. Unfortunately, a prior study, Induced Hypertension for Acute Ischemic Stroke, was terminated, in part because of poor enrollment. Recommendations 1. Arterial hypotension (SBP _120 mm Hg) should be evaluated and corrected, given the strong association with higher mortality. 2. Prospective, randomized trials evaluating induced hypertension are needed. Such trials should also evaluate patient selection on the basis of presenting BP, presence of mismatch, CBF studies, timing of induced hypertension, and agents used. Such trials should include location of vessel involvement, degree of collateral circulation, extent of occlusion, and tissue at risk. 29 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 Randomized trials Only the Controlling Hypertension and Hypotension Immediately Post Stroke (CHHIPS) trial enrolled patients no later than 12 hours from onset into a randomized BP arm. This arm will evaluate induced hypertension in patients presenting with SBP _140 mm Hg. Although the remaining trials are important, they are unlikely to address the question of how to manage the vast majority of hyperacute patients, those typically within the 8-hour time window, who are undergoing an interventional procedure for recanalization. Although not strictly a BP trial, the Safety and Efficacy of NeuroFlo Technology in Ischemic Stroke (SENTIS) trial is currently randomizing patients within 14 hours to partial occlusion of aortic outflow or best management. Data from deployment of this intra-aortic device, which spans above and below the renal arteries, suggests that the procedure can elevate CBF without change in systemic BP. Summary Many patients with acute stroke present with hypertension. There are few data to guide the management of BP within the first 24 hours. Substantial circumstantial evidence suggests that elevated BP might provide needed CBF to penumbral tissue; however, this benefit is associated with higher rates of intracerebral hemorrhage and edema, as well as secondary organ injury to the heart, lungs, and kidneys. Those patients who present with hypotension or relative hypotension (SBP 120–140 mm Hg) are at greatest risk for neurologic deterioration. This group likely has a complex interaction of large strokes and substantial cardiovascular disease. In the absence of data, we agree with the current recommendations of the American Stroke Association for acute management of BP and therefore have highlighted these recommendations and suggested research efforts. 30 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 117 Progressive supranuclear palsy Roohani M Iran University of Medical Sciences, Tehran, Iran The term "multiple system atrophy" (MSA) encompasses three clinical syndromes: olivopontocerebellar atrophy, Shy-Drager syndrome, and striatonigral degeneration. Striatonigral degeneration is now termed MSA with predominant parkinsonism (MSA-P), and olivopontocerebellar atrophy is now termed MSA with predominant cerebellar ataxia (MSA-C). The estimated annual incidence of MSA in the population >50 years old is approximately 3 per 100,000. The mean age of onset ranges from 54 to 60 years. There appears to be no racial or gender predilection. The main clinical features of MSA are akinetic-rigid parkinsonism, autonomic failure, urogenital dysfunction, cerebellar ataxia, and pyramidal signs in varying combinations. The motor features of MSA-P are characterized by akinesia/bradykinesia, rigidity, postural instability, and/or an irregular jerky postural and action tremor. The motor features of MSA-C involve predominant cerebellar dysfunction that manifests as gait ataxia, limb ataxia, ataxic dysarthria, and cerebellar disturbances of eye movements. Dysautonomia is a feature of both MSA-P and MSA-C. Nearly all men with MSA develop early erectile dysfunction. Other common early MSA symptoms include increased urinary frequency, urgency, incontinence, or incomplete bladder emptying. Orthostatic hypotension usually emerges after urogenital symptoms appear. The cause of MSA is unknown. Glial cytoplasmic inclusions are the pathologic hallmark of MSA and contain alpha-synuclein, tau, and ubiquitin. Typical sites of pathologic involvement include the putamen, caudate nucleus, substantia nigra, locus ceruleus, pontine nuclei, inferior olivary nucleus, Purkinje cell layer of the cerebellum, and intermediolateral cell columns.The diagnosis of MSA is based upon the clinical features. No laboratory or imaging studies are diagnostic. Lack of sustained response to levodopa can help to distinguish MSA from idiopathic Parkinson disease, but transient benefit from levodopa is observed in 30 to 50 percent of patients with MSA. It is important to distinguish MSA from idiopathic Parkinson disease and other atypical parkinsonian syndromes (progressive supranuclear palsy and corticobasal degeneration). 31 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 118 New classification of dystonia Habibi SA Mashhad University of Medical Sciences, Mashhad, Iran Dystonia is defined as a movement disorder characterized by sustained or intermittent muscle contractions causing abnormal, often repetitive, movements, postures, or both. Dystonic movements are typically patterned and twisting, and may be tremulous. Dystonia is often initiated or worsened by voluntary action and associated with overflow muscle activation. Dystonia is classified along 2 axes: 1clinical characteristics, including age at onset, body distribution, temporal pattern and associated features (additional movement disorders or neurological features); and 2-etiology, which includes nervous system pathology and inheritance. The clinical characteristics fall into several specific dystonia syndromes that help to guide diagnosis and treatment. We provide here a new general definition of dystonia and propose a new classification. We encourage clinicians and researchers to use these innovative definition and classification and test them in the clinical setting on a variety of patients with dystonia. 32 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 119 Corticobasal Ganglionic Degeneration Safa Najmi Tabriz University of Medical Science, Neurology Department, Tabriz, Iran Corticobasal ganglionic degeneration (CBGD) is a rare progressive neurological disorder characterized by a combination of parkinsonisam and cortical dysfunction. CBGD appears to be closely related to another, less rare, sporadic extrapyramidal degenerative disorder named Progressive Supranuclear Palsy (PSP). In CBGD, cognitive symptoms dominate, while in PSP, eye movement symptoms dominate the picture. The Parkinsonism is generally an asymetric akinetic rigid syndrome, unresponsive to levodopa. Eye movement abnormalities are common. Neuroradiological imaging studies in CBGD demonstrate cortical atrophy, which may be symmetrical or asymmetrical. Other cortical signs include: Alien limb phenomenon, Apraxia, Dysphasia, Cortical sensory loss, and Pyramidal signs. Proposed diagnostic criteria for CBGD include at least three of the following: bradykinesia and rigidity that does not respond to levodopa, alien limb phenomena, cortical sensory signs, focal limb dystonia, action tremor, myoclonus. The "alien limb" symptom is highly specific but it is not necessary for the diagnosis. Onset in the sixth or seventh decade is typical. Disease progression is quicker than in Parkinson’s disease. Pathologically, There is neuronal loss and gliosis and swollen achromatic neurons (ballooned neurons) are found in all cortical layers, but especially so in superior frontal and parietal gyri. There is extensive loss of myelinated axons in the white matter. Ballooned neurons are strongly reactive for phosphorylated neurofilaments and may include the tau protein. Neuronal loss and gliosis are also observed in the nuclei of the basal ganglia. Lewy bodys and neurofibrillary tangles are absent. The substantia nigra shows neuronal loss with extraneuronal melanin, gliosis and neurofibrillary inclusions, called "corticobasal bodies". CBGD is difficult to diagnose in early stages, and experienced examiners typically diagnose it correctly less than 50%. As more cortical signs develop in later stages, the disorders below may be possible to separate. As diagnostic sensitivity is poor, neuropathological confirmation remains the gold standard. The most important differential diagnosis are: Parkinson’s Disease, PSP, MSA and Pick disease. The cause of CBGD is presently unknown but because the tau protein accumulates in this disorder, it may be related to a mutation in the tau gene. Tau is a microtubule-binding protein that is normally abundant in neurons. According to Di Maria et al (2000) and Houlden et al (2001), CBGD shares the same tau haplotype as do PSP patients (see above), suggesting that both CBGD and PSP share the same genetic background, and possibly the same pathologic mechanism. Conventional Treatment: CBGD patients do not respond to levodopa. Management is based on appropriate use of appliances, prevention of medical complications, and appropriate use of nursing. Patients with CBGD and family should establish early on the plan regarding invasive care -- intubation, feeding tubes, as these issues are almost certain to come up in the course of the disease. 33 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 120 Oral therapy in MS: experiences with fingolimod Behnaz Seddighi Department of Neurology, Neurology Research Center, Kerman University of Medical Sciences, Kerman, Iran Treatments of multiple sclerosis (MS) have undergone a revolution over the past 2 decades. The new orally administered drugs approved for MS treatment represent significant therapeutic advances. The oral route of administration clearly promotes patient satisfaction and increases therapeutic compliance. Three oral drugs have been approved by regulatory agencies for the treatment of MS: fingolimod, teriflunomide, and dimethyl fumarate. Fingolimod (Gilenya®) (marela in IRAN) Fingolimod is approved by the FDA for RRMS and in Europe by the European Medicines Agency (EMA) for patients with RRMS and disease activity, despite first-line treatment, or in patients with evolving severe RRMS. It is administered orally as 0·5-mg capsules daily. Fingolimod binds to sphingosine-1-phospate (S1P) receptors on immune cells. Consequently, these immune cells are unable to egress from lymphatic tissue, and subsequently into the CNS. Only lymphocytes that reside within secondary lymphoid organs are affected, which account for approximately 2% of all circulating lymphocytes. In addition to the effects on immune cells, there is emerging evidence that fingolimod may modulate S1P receptors in the CNS and may reduce neurodegenerative processes. The most common side effects of fingolimod are: headache, flu-like symptoms, diarrhoea, back pain, liver enzyme elevations and cough. More severe side effects such as cardiac complications are common, with an incidence between 1 and 10% of patients treated with fingolimod. A first-degree atrioventricular block was reported in about 4·7% in patients treated with 0·5 mg fingolimod. Other risks include a minor increase in blood pressure, decrease in lung function, macular oedema and an increased frequency of viral infections, in particular varizella zoster. Macular oedema may lead to progressive visual loss. In two Phase III trials, 13 patients developed macular oedema, 10 of them within the first 4 months of treatment. Patients may report blurred vision or decreased vision or may be asymptomatic. The incidence is about 0·4% in the 0·5 mg group, with a higher incidence with patients with a history of uveitis. After termination of therapy, macular oedema usually resolves spontaneously; (evaluation of the fundus ; prior to initiation of therapy, within 4 months after onset of therapy and at any time of decreased visual acuity ). Eleven of the 13 patients with macular oedema were administered a dose that is more than twice as high as the currently approved dose. Cutaneous neoplasias were reported more often in the fingolimod group than in the IFN or placebo control groups. Basaliomas and melanomas (in situ) were reported. (dermatology screening examination before the initiation). In the context of one Phase II clinical trial, one MS patient died from varicella zoster infection and consecutive hepatic failure, and another patient died from herpes simplex virus 1 encephalitis. A third patient was diagnosed with a life-threatening HSV encephalitis. All these patients were treated with the higher, non-approved 1·25 mg dose. FDA and EMA currently recommend 6-h heart monitoring with continuous ECG monitoring during the first administration of fingolimod. If bradycardia occurs within the first 6 h, cardiac monitoring should be extended for another 2 h. The occurrence of severe bradycardia, QTC interval prolongation, AV block II Wenckeback or AV block III requires overnight observation. In patients with atrioventricular block II, significant QT-prolongation, symptomatic known bradycardia or history of syncope, ischaemic heart disease or history of myocardial infarctions or cerebrovascular infarction, uncontrollable arterial hypertension or congestive heart disease, fingolimod cannot be recommended. Because of the first-dose cardiac side effects of fingolimod, cardiac monitoring has to be repeated in all patients who experience a treatment hiatus of 14 days or longer. Additionally, the EMA requires for repeated monitoring when the treatment is interrupted for 1 day during the first 2 weeks of treatment, or 7 days during week 3 and 4 of treatment. Moreover, the majority of cases with macular oedema occurred within the first 3–4 months after onset of therapy. Patients may report blurred 34 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 vision or decreased vision or may be asymptomatic. The incidence is about 0·4% in the 0·5 mg group, with a higher incidence with patients with a history of uveitis. After termination of therapy, macular oedema usually resolves spontaneously; (evaluation of the fundus ; prior to initiation of therapy, within 4 months after onset of therapy and at any time of decreased visual acuity). Vaccination: during therapy with fingolimod may be less effective. Vaccination with live attenuated virus vaccines should be avoided during, and 2 months after, fingolimod therapy as it may carry the risk of infections. In addition, patients without a history of chickenpox or vaccination against varicella zoster virus (VZV) should be tested for VZ antibodies. Vaccination is recommended 1 month prior to initiation with fingolimod therapy in order to ensure immunization. Monitoring of therapy should also include complete cell counts at initiation of therapy, months 1, 3 and 6 and in periodic intervals thereafter. Fingolimod has been assigned to pregnancy category C by the FDA. If a patient becomes pregnant during treatment, application of fingolimod should be terminated. Recently there were 1 report of PML. Teriflunomide (Aubagio®) Teriflunomide was approved in 2012 by the FDA for treatment of relapsing forms of MS. Teriflunomide has anti-inflammatory properties. Teriflunomide is available in two doses: 7 or 14 mg once daily in the United States and 14 mg in Europe. Adverse effects of teriflunomide include decreased white blood count (WBC), and infections. Specifically, cases of tuberculosis were reported. Polyneuropathy, renal failure, skin reactions, hair thinning and an increase in blood pressure have also been observed. Teriflunomide is contraindicated in patients with severe hepatic injury. In the case of immunodeficiency teriflunomide should not be administered.Vaccinations with live vaccines are not recommended. Teriflunomide has been assigned category X by the FDA. Dimethyl fumarate (Tecifidera®) Dimethyl fumarate was approved by the FDA for treatment of RRMS, and on 21 March 2013. The CHMP at the European Medicines Agency (EMEA) adopted a positive opinion for marketing authorization for Tecifidera® 120-mg and 240-mg capsules for the treatment of RRMS. Flushing was reported in up to 40% of the treated patients. In fewer than 1% of treated patients, flushing led to hospitalization. Gastrointestinal side effects such as vomiting, abdominal pain, diarrhoea and dyspepsia were more common in the dimethyl fumarate group when compared to the placebo group. Recently, there were two reports of PML. Dimethyl fumarate has been assigned pregnancy category C. 35 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 121 Rehabilitation protocols in MS: An Iranian guideline Mojtaba Azimian University of Social Welfare and Rehabilitation Sciences, Tehran, Iran Multiple Sclerosis (MS), is one of the progressive diseases which diffusely involves the central nervous system and manifest different signs and symptoms. In modern therapeutic approach, not only the immunomodulatory medications are administered, the rehabilitation approaches are stressed as well. Rehabilitations are considered initially and protocols of better diagnosis and better prevention are considered. This latter fact enables patient to have a better quality of life and social functioning from the initial period up to the end. The harmonized cycle of prescribing suitable medical remedy based on the appropriate guideline, will also benefit the patients likewise. Such unified success may be attributed to a reasonable teamwork approach rather than an individually act. Team members may include physicians, nurses, physiatrists, physical therapists, speech and language pathologists, psychologists, social workers, recreation therapists, patients and their relatives, who have some correlations in such team work therapy. The team can relate their experiences to assure a better and risk-free life for the MS patients. Some possible MS complications, may be as follows: 1. Impairments, which includes the neurological symptoms of the disease 2. Disability, which declines the patient`s functional efficacy 3. Handicap, which the patient`s social participations are deteriorated Manifestations and alternations of any following sign and symptoms, emphasizes the team intervention based on a proper MS guidelines: fatigue, weakness, spasticity, balance and moving deterioration, pain, cognition, mood, relationships, bowel and bladder function, swallowing, speech, sexual function, recreation, employment, transportation, ADL (eating, bathing, dressing and household chores). Intervention for alleviating any of the above issues, may be stated via guideline use. Each action, must be standardized based on patients who belong to different background with different facilities. Recently, in Iran the appropriate and native-made guidelines have been introduced, for a better and effective ways of MS patients` treatment. 36 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 122 Longterm Efficiacy of Beta-Interferons in Multiple Sclerosis Thomas Berger Clinical Department of Neurology, Medical University of Innsbruck, Austria Multiple sclerosis (MS) is a potentially devastating inflammatory demyelinating disease of the central nervous system (CNS) affecting approximately 1:1000 mainly young adults. Relapsing-remitting MS (RRMS), characterized by an individual frequency of relapses, bears the risk of incomplete remissions and further progressive disability, then termed as secondary progressive MS (SPMS). A disease modifying therapy (DMT) describes a drug, which modulates MS disease course either as an immunosuppressant or immunomodulator. Between 1995-2001 the first DMTs have been approved in different countries to reduce relapses and, to some extent, delay disease progression. These standard (or baseline) DMTs for RRMS include interferon-beta (IFNb) preparations (IFNb-1a 30 mg qw i.m., IFNb-1a 22/44 mg tiw s.c., IFNß-1b 250 mg qod s.c) In general, IFNb has a favourable benefit-risk profile, which has been documented by longterm studies and postmarketing surveillance for more than 20 years. AE’s of IFNb, such as injection-site reactions (including rare skin necrosis) and flu-like symptoms, usually depend on application routes (i.m. << s.c.) and the drug itself, and are not serious, but may negatively impact quality of life. Thus, in the treatment decision-making process we should recall that it is the patient, who takes the risk – either for her/his potential MS disease consequences or potential DMT side-effects/risks. Therefore, benefit-risk evaluations and perceptions are likely to vary among patients and between patients and their physicians. 37 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 123 Advanced Parkinson management with focus on role of Apomorphine Angelo Antonini Parkinson and Movement Disorders Unit, IRCCS San Camillo Hospital, Venice – 1st Neurology Clinic, University Hospital of Padua, Italy Apomorphine is the oldest dopaminergic medication and was initially known for its emetic properties. It was initially used for Parkinson’s disease over 60 years ago but later ignored for many years following levodopa introduction. It is also the most potent dopamine agonist and its administration can provide symptom relief comparable to levodopa. Apomorphine exerts its antiparkinsonian effect by direct stimulation of striatal postsynaptic dopamine D1 and D2 receptors. The drug has a rapid absorption after subcutaneous injection (Cmax 20 min), and a short half-life (almost 43 min), and this is consistent with its rapid onset of action, with effects apparent within 5–15 minutes of subcutaneous administration. Clinical studies and evidence-based reviews generally support a role for apomorphine infusion as an effective option for patients with PD and severe fluctuations, poorly controlled by conventional oral drug treatment with an improvement in OFF-time between 50% and 80% as well as dyskinesia. While the benefit on off time is consistent across all studies, dyskinesia improvement generally occurs after a few weeks or months of continuous dopaminergic stimulation as a result of wider therapeutic window. Moreover it can be best achieved with apomorphine monotherapy that may require high infusion doses. Intermittent subcutaneous apomorphine (penjet) may instead be suitable for the long-term acute treatment of OFF episodes in patients with advanced PD. Apomorphine injections can be a particularly helpful in the management of patients who undergo surgical procedures and cannot take medication by mouth or to treat additional severe non-motor symptoms occurring during OFF periods. 38 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 124 Update ALS 2015 Reinhard Dengler Department of Neurology, Hannover Medical School, Hannover, Germany The presentation will deal with new scientific and clinical develepments in the field of amyotrophic lateral sclerosis (ALS). In genetics, about 60 – 70 % of the mutations in familial ALS have been identified, the most frequent being the C9ORF72 mutation. Similarly to other neurodegenerative disorders, ALS is characterized by intracellular inclusion bodies. It could be shown very recently that they contain aggregates of the protein TDP43 which may propagate from neuron to neuron in a prion-like manner. TDP43 can also be found in cases with frontotemporal lobe dementia (FTLD) and it is now accepted that about 30 % of ALS patients develop FTLD. The gold standard of ALS diagnosis are still the revised El Escorial Criteria which have now been supplemented by the so called Awaji electrodiagnostic Criteria (AC). The AC regard fasciculation potentials in EMG as a sign of active denervation like positive waves and fibrillations. The detection of upper motor neuron signs in ALS may be difficult. Modern imaging is currently not yet able to detect upper motor neuron involvement on an individual level. Special techniques of transcranial magnetic stimulation may, however, prove helpful. Riluzole is still the only drug approved for treatment of ALS. Unfortunately, clinical trials with various drugs in the last two decades have remained unsuccessful. Great hope is now associated with cell transplantation and nonsense oligonucleotides in familial ALS. Currently, however, symptomatic treatment is important to improve quality of live including assistance in nutrition and respiration and finally palliation. 39 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 125 Treatment of Neurodegeneration with Brain Iron Accumulation (NBIA) Thomas Klopstock Friedrich-Baur-Institute, Dept. of Neurology, Ludwig-Maximilians-University, Munich, Germany Neurodegeneration with brain iron accumulation (NBIA) is a clinically and genetically heterogeneous group of rare hereditary neurodegenerative disorders. The most common form, accounting for approximately 50% of NBIA cases, is pantothenate kinase-associated neurodegeneration (PKAN). While there is no proven therapy to halt or reverse any form of NBIA, symptomatic treatment including deep brain stimulation can markedly alleviate symptoms. Beyond that, NBIA may be feasible for a causal therapy as the accumulation of iron in the brain may be addressed biochemically by iron chelation. TIRCON (Treat Iron-Related Childhood-Onset Neurodegeneration), an international collaborative project funded by the European Commission´s Seventh Framework Programme, addresses this urgent and unmet need for a therapy for NBIA/PKAN by conducting a randomized placebo-controlled clinical trial of the iron chelator deferiprone in PKAN (duration per patient 18 months). The four study sites in Munich (Germany), Oakland (USA), Milan (Italy) and Newcastle (UK) have already fully recruited this pivotal trial by randomizing 89 PKAN patients. The last patient-last visit (LPLV) is scheduled for August 2016. An extension trial, sponsored by the manufacturing company ApoPharma, has already started for the patients who complete the randomized trial. Regular meetings of the Data Safety Monitoring Board identified no major safety issues with deferiprone so far. TIRCON has already succeeded in bringing together into one cohesive group the existing outstanding but scattered expertise in NBIA research and care at the European and international level. Medical care and research infrastructure have already noticeably improved, and the NBIA community is eagerly awaiting the outcome of the therapy research outlined above. 40 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 126 Normal Pressure Hydrocephalus: New Concepts in Diagnosis and Treatment Saeed Ghazvinian Neurology Department, Bank Melli Hospital, Tehran, Iran Normal Pressure Hydrocephalus (NPH) was first described by Colombian neurosurgeon Salomon Hakim in the 1960s and is thought to account for about 2-5% of dementia cases. NPH is an important entity to recognize due is reversibility. The classic triad suggestive of NPH includes a gait disorder, cognitive impairment and urinary incontinence. Among these elements, the gait disorder is most critical because it is present in nearly all cases and can be helpful in making the diagnosis. The cognitive deficits are not always dramatic and when present typically take the form of '' subcortical'' impairment. Despite the classic triad, NPH can be challenging to diagnose considering how common these problems are in the elderly and therefore how frequently they co-exist by chance. Because of this, the presence of NPH is best judge as an estimate of the degree to which the hydrocephalus contributes to an individual patient's disability. Accordingly, published guidelines recommended cases be classified as either probable NPH, possible NPH or unlikely NPH. Management of NPH also is a challenge as not all persons who have the syndrome respond well to treatment. Enlarge ventricles seen on CT or MRI are insufficient in predicting who will be respond to surgical shunting of ventricles. More sophisticated neuroimaging techniques based on ways of measuring CSF flow and hemodynamics are also sometimes employed. Depending on the method of patient selection and how a favorable response to shunting is defined, the rate of positive outcomes to ventricular shunting in NPH has been found to be in the range of 61-75%. New concepts about pathophysiology, diagnosis and treatments of NPH will be discussed in congress. 41 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 127 Survey of Autonomic Symptoms (SAS) questionnaire compared with Sympathetic Skin Response (SSR) results in patients with diabetic autonomic neuropathy Fariborz Khorvash, Majid Ghasemi, Mohammad Hosein Safari Isfahan Neurosciences Research Center, Isfahan University of Medical Sciences, Isfahan, Iran BACKGROUND: Diabetic autonomic neuropathy is a serious and common complication of diabetes. There is a need to develop a simple instrument to measure autonomic symptoms in subjects with neuropathy and to test the validity of the instrument. Using a questionnaire survey of autonomic symptoms (SAS) for screening of diabetic autonomic neuropathy is a new procedure. Sympathetic skin response (SSR) is a method for the study of autonomic nervous system. SSR was more often absent in patients with symptoms of dysautonomia. PURPOSE: Given the importance of diabetes and its complications autonomic, in this study, data obtained from questionnaires SAS Scale test is compared with the SSR. METHODS: This is a cross-sectional study. In patients with a diagnosis of diabetes with at least one symptom of autonomic dysfunction, which were referred to the clinic of Neurology and Clinical Endocrinology, after obtaining written informed consent, a SAS questionnaire was completed and SSR was assessed by EMG recording. The Survey of Autonomic Symptoms (SAS) consists of 11 items in women and 12 in men. Each item is rated by an impact score ranging from 1 (least severe) to 5 (most severe). RESULTS: The SAS was tested in 135 subjects with neuropathy and impaired glucose tolerance or newly diagnosed diabetes. The average scores of SAS in patients was 16.82 (±12.62), the least of which was 1 and the maximum is 50, that was not significantly related to age and gender. Of the total patients, 60 (44.4%) had positive SSR response and 75 patients (55.6%) had a negative SSR response. In the examining with independent T-test, there was a significant association between response of SSR with a score of SAS (P<0.001). In ROC Curve Analysis, numeric value of the SAS score equal to 9.5 with a sensitivity of 88% and specificity of 70% as the cutpoint and SAS score of 13.5 with 80% sensitivity and 90% specificity was obtained as a cutpoint for SSR response. CONCLUSION: The SAS is a new, valid, easily administered instrument to measure autonomic symptoms in early diabetic neuropathy and would be of value in assessing neuropathic autonomic symptoms in clinical trials and epidemiologic studies. 42 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 128 Trace blood elements and severity of Parkinson's disease Ahmad Chitsaz, Rokhsareh Memar, Mohammad Reza Aghaye-Ghazvini Isfahan University of Medical Sciences, Isfahan, Iran BACKGROUND: Parkinson's disease (PD) is a degenerative disorder of the nervous system and it seems that disturbances in trace elements homeostasis mediate progression of disease. PURPOSE: The aim of this study was to compare the levels of trace elements (Fe, CU and Zn) in various PD stage and assess their correlation with the severity of PD. METHODS: Serum concentrations of trace elements were measured on Hitachi 902 biochemistry analysis in 109 PD patients. Then severity of disease was evaluated according to Hohn & Yahr (HY) in four stages of 1-1.5, 2-2.5, 3 and 4-5, and also motor part of unified PD rating scale III (UPDRS- III) were used. RESULTS: All trace elements levels were within normal reference valves and did not differ significantly between different HY stage (Fe: P=0.670, CU= 0.540, Zn=0.340: P=0.34). Only patients with higher HY stage were older (P=0.026). When the severity of PD was evaluated by UPDRS-III only there were significant association between age and severity of disease (P=0.024). CONCLUSION: In this study, we confirmed only age as a factor that was correlated with severity of PD for clarifying actual role of trace elements, in PD. However, more studies should be designed. 43 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 129 Evaluation of the efficacy and safety of Vicia faba Extract in the treatment of patients with Parkinson’s disease Karim Nikkhah, Samira Aminzadeh, Ali Ghabeli Juibary, Hasan Rakhshandeh, Valyollah Kashki, Mohammad Mahdi Charkhandeh, Hamid Sadeghian, Hamidreza Sadeghnia, Ali Shoeibi Department of Neurology, School of Medicine, Mashhad University of Medical Sciences, Mashhad, Iran BACKGROUND: Parkinson’s disease (PD) is a chronic degenerative disease of the central nervous system with no definitive treatment. PURPOSE: We aimed to study the efficacy and safety of Vicia faba extract, as an easily accessible herbal remedy, on different clinical findings of patients with Parkinson Disease. METHODS: Twenty male and 10 female patients with definite diagnosis of PD, aged between 51 and 81 years, were enrolled in this clinical trial. PD was diagnosed based on clinical findings and on ruling out all other causes of Parkinsonism. RESULTS: Both Fava extract- carbidopa combination and conventional levodopa-carbidopa were significantly effective in alleviating the main clinical findings of patients. There was no significant difference between Fava group and levodopa-c group regarding improvement of rigidity, rising from chair, gait disturbance, and postural instability of patients one week after consumption of the medication. However, conventional levodopa-carbidopa was superior to Fava extract in reducing tremor at rest and freezing. In both levodopa and extract group, serum levels were in therapeutic range (1-3 μgr/dl). CONCLUSION: Despite the higher Levodopa serum level in patients who had received conventional levodopa, those who had used Vicia faba extract showed almost the same clinical improvement with significantly lower side effects. 44 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 130 Association between sleep quality and cognitive status in patients with Parkinson's disease without dementia Narjes Sahebzadeh1, Arezou Farag Pour2 1-Faculty of Medicine, Mashhad Branch, Islamic Azad University, Mashhad, Iran 2-Shahid Beheshti University of Medical Science, Tehran, Iran BACKGROUND: Sleep disturbances and cognitive impairment are two common non-motor symptoms of Parkinson's disease (PD). PURPOSE: The study aim was to evaluate the cognitive status and sleep quality and the association between cognitive impairment and sleep quality as well as daytime sleepiness in PD patients. METHODS: In this analytical cross-sectional study, 120 patients with PD were selected from 22-Bahman and 17-Shahrivar hospitals. Demographic information was filled in the form and Parkinson severity was determined using the Hoehn and Yahr scale (HY). Pittsburgh Sleep Quality Index (PSQI) and Epworth sleepiness scale (ESS) were used for assessment of sleep quality and excessive daytime sleepiness, respectively. Cognitive status was assessed by using Montreal Cognitive Assessment (MoCA) questionnaire. RESULTS: Mean age of PD patients was 65.9±11.7 yrs and 67.5% of them were male. Mean duration of PD was 2.7±2.6 yrs. Majority of the patients were in stage I or II of the disease. Mild cognitive impairment (MCI) was found in 113 (94.2%), poor sleep quality in 87 (72.5%) and excessive daytime sleepiness in 27 (22.5%) PD patients. Mean PSQI and ESS scores in PD patients was 9.03±4.70 and 7.38±3.73, respectively. There was a significant association between cognitive status and sleep quality as well as daytime sleepiness (p<0.0001). CONCLUSION: There is a significant association between MCI and poor sleep quality. In addition excessive daytime sleepiness and MCI is found in 100% of patients with sleep disorder. However, sleep quality was not predictor of MCI. Therefore, assessment of cognitive status is recommended in all PD patients with sleep disturbances. 45 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 131 Improvement of spinal contusion model by cotransplanting bone marrow stromal cells (BMSCs) and induced BMSCs into oligodendrocytes-like cells Gholamreza Kaka Neuroscience Research Center, Baqiyatallah University of Medical Science, Tehran, Iran BACKGROUND: Demyelination is a common lesion in spinal cord injury. Cell therapy is one of the approaches for replacing the lost oligodendrocytes. In this study, bone marrow stromal cells (BMSCs) have been transdifferentiated into oligodendrocyte--like cells (OLCs) and used in cytotherapy of contused spinal cords in rats. METHODS: The BMSCs were collected from the rat long bones, and cultured and characterized by different markers, then they were preinduced with dimethyl sulfoxide followed by retinoic acid, and then the preinduced cells were induced with combination of basic fibroblast growth factor (bFGF), platelet-derived growth factor (PDGF) and heregulin (HRG), followed by triiodothyronine (T3). The OLCs were transplanted in the contused spinal cords of the rats, combined with undifferentiated BMSCs. Specific markers were used in order to characterize the cells by immunohistochemistry and RT--PCR. The BMSCs showed typical immnuoreactivity to the markers, and the OLCs were immunostained with specific markers. RESULTS: There was an improvement in BBB test with reduction in the cavitation in the contused rats treated with OLCs combined with BMSCs. The transplanted cells were detected in the contused spinal cord. CONCLUSION: The combination of the transdifferentiated BMSCs into OLCs with the undifferentiated BMSCs improved the contused spinal cord. 46 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 132 The first study of COX-2 gene variants and risk of migraine in Iranian patients Elahe Mozaffari1, Abbas Doosti1, Reza Nemati2, Morteza Makhlooei3 1-Biotechnology Research Center, Islamic Azad University, Shahrekord Branch, Shahrekord, Iran 2-Department of Neurology, Faculty of Medicine, Boushehr University of Medical Sciences, Bushehr, Iran 3-Department of Agriculture Science, Faculty of Agriculture, Boushehr Branch, Islamic Azad University, Boushehr, Iran BACKGROUND: Migraine is a common debilitating head pain disorder with reversible acute pain attacks and complex etiology which associated to temporal changes of head blood vessels. It is characterized by episodes of intense unilateral pulsating head pain and often associated with nausea, vomiting and photophobia and phonophobia. It has two main types; migraine with aura and migraine without aura are introduced by the International criteria for Headache Society (IHS). PURPOSE: This study was performed to investigate the association between COX-2 gene polymorphisms and the risk of migraine susceptibility and to discover its association with parent marriage types for the first time in Iran. METHODS: Genomic DNA of blood tissue was extracted from 100 migraine cases and 100 migraine free subjects. The PCR was accomplished by the appropriative primers to amplification the slightly region of COX-2 gene. Then expected fragments were digested with endonuclease restriction enzymes and the DNA fragments were resolved by electrophoresis in 2% agarose gel. RESULTS: There was a significant difference in the frequency of the COX-2-765G→C and COX-2-1195A→G genotypes between controls and migraine cases (P≤0.05). Also our results show that COX-2-765CC, COX2-765CG, COX-2-1195GG and COX-2-1195AG genotypes can increase the risk of migraine significantly and its significant relation with familial marriage was observed. CONCLUSION: We are hopeful to achieve more useful results about the relevancy of other regions of COX2 gene, migraine, pain signals pathway and the other illnesses by repeating these experiments on more extensive samples. 47 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 133 Elevated Troponin T after acute ischemic stroke: Association with severity and location of infarction Siamak Abdi, Asgar Ghorbani, Shahram Oveis Gharan, Farnaz Sinaei Neurology Department, Shariati Hospital (TUMS), Tehran, Iran BACKGROUND: Serum Troponin elevation, characteristic of ischemic myocardial injury, has been observed in some acute ischemic stroke patients. Its cause and significance is still controversial. PURPOSE: The purpose of this study is to find determinants of Troponin elevation and its relationship with stroke severity and location. METHODS: Between January 2013 and August 2013, 114 consecutive acute ischemic stroke patients confirmed by diffusion weighted Magnetic Resonance Imaging were recruited in this study. Serum Troponin T level was measured as part of routine laboratory testing on admission. Ten lead standard ECG was performed and stoke severity was assessed based on National Institutes of Health Stroke Scale (NIHSS). RESULTS: Troponin T was elevated in 20 (17.6%) of 114 patients. Patients with elevated Troponin were more likely to have higher age, higher serum creatinine and ischemic electrocardiographic (ECG) changes. Troponin levels were higher in patients with more severe stroke measured by NIHSS (7.96 (6.49 – 9.78) vs. 13.59 (10.28 – 18.00)). There was no association between Troponin and locations of stroke and atrial fibrillation. There were 6 (5%) patients with elevated Troponin in the presence of normal creatinine and ECG. CONCLUSION: Stroke severity, not its location, was associated with higher Troponin levels. Abnormal Troponin levels are more likely, but not exclusively, to be due to cardiac and renal causes than cerebral ones. 48 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 134 The evaluation of the relationship between plasma concentrations of Carbamazepine and Carbamazepine 10, 11 epoxide and polymorphism of SCN1A and SCN1B genes in Iranian epileptic patients Soha Namazi1,2, Negar Azarpira3, Katayoon Javidnia4, Mehrdad Emami5, Rahimeh Rahjoo2, Razieh Berahmand2, Afshin Borhani-Haghighi6,7 1-Clinical Neurology Research Center, Shiraz University of Medical Sciences, Shiraz, Iran 2- Department of Pharmacotherapy, School of Pharmacy, Shiraz University of Medical Sciences, Shiraz, Iran 3-Transplant Research Center, Shiraz University of Medical Sciences, Shiraz, Iran 4-Department of Medicinal Chemistry, School of Pharmacy, Shiraz University of Medical Sciences, Shiraz, Iran 5-Transgenic Technology Research Center, Shiraz University of Medical Sciences, Shiraz, Iran 6-Clinical Neurology Research Center, Shiraz University of Medical Sciences, Shiraz, Iran 7-Department of Neurology, School of Medicine, Shiraz University of Medical Sciences, Shiraz, Iran BACKGROUND: Understanding the relevance of SCN1A and SCN1B genes polymorphism to plasma concentration of Carbamazepine (CBZ) and its active metabolite carbamazepine 10, 11 epoxide (CBZE), may help detect inter-individual variation in response to CBZ. METHODS: In this cross-sectional study, genotypes of SCN1A and SCN1B genes were determined using PCR-RFLP in 70 epileptic patients on CBZ for at least 6 months. The patients had no hepatic or renal diseases and received no medications known to have major interaction with CBZ. Serum concentration of CBZ and CBZE was measured using High-Performance Liquid Chromatography. RESULTS: The AA, AG and GG alleles of SCNIA were present in 23, 37 and 10 patients respectively. There were no statistically significant differences in the mean (±standard deviation) of plasma concentrations of CBZ (P=0.8) and CBZE (P=0.1) among these 3 groups. Likewise, there was no statistically significant relationship between SCNIA polymorphism and CBZ concentration/dose ratio (P=0.7). Moreover, there were no statistical associations between demographic characteristics such as age, body surface area, body mass index, ideal body weight and the plasma levels of CBZ and CBZE, and CBZ concentration/dose ratio. All patients had the same genotype of SCN1B gene, so we were unable to evaluate its relationship with corresponding variables. CONCLUSION: No significant relationship between polymorphism of SCN1A gene and plasma level of CBZ and CBZE was found. 49 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 135 Sleep disorders as differential diagnosis for epilepsy: a case series presentation Hadi Asadpour1, Fariborz Rezaee Talab2, Lahya Afshari Saleh3 1-The sleep laboratory of Ebn-e-Sina Hospital, Mashhad University of Medical Sciences, Mashhad, Iran 2-The sleep lab of Ibn-e-Sina Hospital and Ghaem hospital, Mashhad University of Medical Sciences, Mashhad, Iran 3-The sleep lab of Ibn-e-Sina hospital and Department of Occupational Medicine, Mashhad University of Medical Sciences, Mashhad, Iran BACKGROUND: Sleep and epilepsy are common bed fellows and sleep disorders may mimic, cause or be triggered by epilepsy phenomena and vice versa. Normal sleep phenomena (including hypnic jerks and nightmares), parasomnias (confusional arousals, sleep terrors, enuresis), some aspects of narcolepsy (including sleep paralysis, automatism, cataplexia) and sleep-related breathing disorders (including obstructive sleep apneas) may mimic epileptic seizures. On the other hand, nocturnal epileptic attacks may cause or trigger sleep disorders such as apnea, repeated arousals and excessive daytime sleepiness. CASE PRESENTATION: Here, four cases of sleep disorders (including obstructive sleep apnea, Non-REM parasomnia, REM-sleep behavior disorder, and narcolepsy) who were previously misdiagnosed as epilepsy will be brought forward and their polysomnographic features (including videos) will be presented. C CONCLUSION: Having an appropriate knowledge of the broad spectrum of sleep disorders is essential for neurologists who work in the field of epilepsy. 50 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 136 Antidopaminergic Effects of Ascorbic Acid in Central Nervous System: A Basic and Clinical Study Hassan Khani1, Davood Farzin2, Mehran Zarghami2, Seyed Hamzeh Hosseini2, Sara Ehteshami2 1-Iranian Applied Research Center for Public Health and Sustainable Development (IRCPHD), North Khorasan University of Medical Sciences, Bojnurd, Iran 2-Mazandaran University of Medical Sciences, Sari, Iran BACKGROUND: Ascorbic acid an antioxidant vitamin is found throughout the mammalian central nervous system. There is evidence that it may modulate neuronal activity, release of neurotransmitters and dopamine receptors activities. There are behavioral evidences supporting the antidopaminergic effect of ascorbic acid. The purpose of the present study was to determine the interaction between ascorbic acid and the stereotyped licking behavior in rat and a trial of ascorbic acid in schizophrenic patients to evaluate its therapeutic effects. METHODS: A) In the present study, effects of ascorbic acid and different dopamine receptor antagonists on apomorphine-induced licking behavior were examined. For the induction of licking, the dose of 0.5 mg/kg, s.c. of apomorphine was used and the number of licking was recorded over a 75 min period. B) In a randomized, double-blind, placebo-controlled clinical trial 40 patients with schizophrenia were assigned to haloperidol plus ascorbic acid or haloperidol plus placebo. After a washout period, 20 patients received 20 mg/day of haloperidol plus placebo and 20 received haloperidol plus 1500 mg/day of ascorbic acid for 6 weeks. Data analysis was done by repeated-measure analysis of variance, NewmanKeuls and Spearman’s Coefficient Rank Correlation and Chi square method. RESULTS: A) Ascorbic acid (200-350 mg/kg, s.c.) dose-dependently reduced the licking behavior. Subcutaneous injection of ascorbic acid (250 mg/kg, ED61) potentates the inhibitory effect of dopamine D1 receptor antagonist, SCH 23390 (0.5 and 1 mg/kg, i.p.) but did not alter the inhibitory effect of dopamine D2 receptor antagonist, sulpiride (25 and 50 mg/kg, s.c.). B) Over 6 weeks, the ascorbic acid group showed significantly greater improvement in scores on total Brief Psychiatric Rating Scale and on positive, negative and general symptoms subscales. CONCLUSION: These results suggest that the inhibitory effect of ascorbic acid on apomorphine-induced licking behavior is mediated by dopamine D2 receptor mechanisms. Oral supplementation of vitamin C with conventional antipsychotic drugs can be used in the treatment of schizophrenia. 51 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 137 Tumor features may predict postoperative outcome in patients with tumor-associatedepilepsy Jafar Mehvarihabibabadi, Houshang Moein, Reza Basiratnia, Majid Barekatain, Mohammad Zareh, Elham Rahimian, Amirali Mehvari habibabadi, Shervin Badihian Isfahan Neurosciences Research Center, Isfahan University of Medical Sciences, Isfahan, Iran & Kashani comprehensive Epilepsy Center, Isfahan University of Medical Sciences, Isfahan, Iran BACKGROUND: Epilepsy is a manifestation of some brain tumors that has important clinical and social implications and can be controlled by surgery or administration of antiepileptic drugs. It is suggested that tumor site and pathology may affect surgery outcome. PURPOSE: In this study we investigated seizure control after surgery in different tumor locations and histology. METHODS: The medical records of 35 individuals (18 female and 17 male, age: 8-45) with tumor associated epilepsy were reviewed for tumor location, histology, seizure type, ictal and interictal pre/postoperative EEG findings. All the patients were cases of refractory epilepsy who underwent tumor resection surgery and were followed for 2 to 4 years in Kashani comprehensive epilepsy center, Isfahan, Iran. RESULTS: Thirty patients (88.2%) presented with complex partial seizures (automotor and hypermotor) and the rest had simple partial seizures and secondary generalization. Seizure type was not significantly related to postoperative outcome. Ganglioglioma and astrocytoma were the most frequent tumors (61.8% and 29.4% respectively). DNET was reported in 2 cases and pleomorphic xantoastrocytoma in one case. Surgical outcome was not different in different tumor types. In our cases temporal lobe tumors consisted 64.7% of patients and the rest of tumors were located in frontal and parietal lobe (17.6% and 11.8% respectively). Although tumor location was not significantly predictive of surgical outcome, patients with frontal lobe tumors showed less favorable outcome. Patients who had abnormal EEG findings in parietal lobe became free of seizures after surgery. Also patients with abnormal EEG findings in temporal lobe showed better results compared to frontal lobe. The differences were statistically significant. Postoperative EEG demonstrated abnormal findings in 33.3% of patients. Patients with abnormal postoperative EEG had poorer seizure control after surgery although it was not statistically significant. CONCLUSION: Some authors have suggested postoperative seizure control should be investigated by the type of tumor and its location. Few studies have shown more favorable postoperative outcome in temporal lesions compared to extra-temporal ones, while some others have reported same results in both groups. In this study favorable outcome was seen in both groups although patients with frontal lobe tumor had poorer seizure control. Abnormal EEG findings in frontal lobe resulted in poorer seizure control as well. The outcome was not affected by tumor histology. It is believed that slow-growing tumors show poorer seizure control after surgery probably due to secondary generalization. The difference may be explained by little variation in tumor types in our study. Larger studies with more diversity of tumor types are recommended to achieve more precise findings. 52 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 138 Modified Atkins Diet in adult patients with refractory epilepsy: a controlled randomized clinical trial Mohammad Zare, Ali Asghar Okhovat Souraki, Ahmad Esmaillzadeh, Jafar Mehvari, Mohammad Reza Najafi, Mohammad Saadatnia Isfahan University of Medical Science, Department of Neurology, Isfahan Neuroscience Research Center, Isfahan, Iran BACKGROUND: The usefulness of the modified Atkins Diet (mAD) in refractory epilepsy in adults has been rarely investigated. PURPOSE: We aimed to evaluate the efficacy of mAD in adult with refractory epilepsy. METHODS: In a controlled randomized clinical trial, we enrolled 66 refractory adult epileptic cases from February 2010 to December 2012. The Patients were divided into two groups randomly. Case groups (22 patients) used antiepileptic drugs and mAD and control group (32 patients) only use antiepileptic drugs. The primary outcome was at least 50% decrease in seizure frequency after 2 months of therapy. RESULTS: Our data showed no significant difference between groups regarding baseline characteristic. The differences of mean seizure attacks after two months (p≤0.001) and fifty percent reduction in seizure frequency between the two groups showed significant differences [p≤0.001, Odd ratio=2.19, 95% confidence interval (1,39, 3.47)]. There was a positive correlation between the mean urinary Ketone level and >50% seizure reduction in case group (p=0.04). In repeated measures analysis and based on the perprotocol principle, there was a significant difference between Modified Atkins Diet and control groups regarding mean number of seizure attacks (F=14.6, p<0.001). Such differences were also significant in the intention- to- treat analysis (F =6.14, p=0.01). CONCLUSION: The mAD may be effective as a co-therapy treatment for adults with refractory epilepsy and can decrease 3.66 times seizure frequency in comparison with control groups. Trials with more tolerant dietary regime, with larger sample size and longer duration, should be performed in the future. 53 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 POSTER PRESENTATION 54 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 CEREBROVASCULAR DISEASES 55 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 139 Mechanical thromboembolectoy versus IV rtPA in treatment of acute ischemic stroke Askar Ghorbani, Siamak Abdi, Vahireza Ostovan Tehran University of Medical Sciences, Tehran, Iran Intravenous alteplase administered within 4.5 hours after symptom onset is the only reperfusion therapy with proven efficacy in patients with acute ischemic stroke. However, it appears to be much less effective at opening proximal occlusions of the major intracranial arteries, which account for more than one third of cases of acute anterior-circulation stroke. Therefore, intraarterial treatment is regarded as a potentially important component of the therapeutic armamentarium. Intraarterial therapy can be broadly divided into chemical dissolution of clots with locally delivered thrombolytic agents and clot retrieval or thrombectomy with mechanical devices. Interventional Management of Stroke (IMS) III trial and SYNTHESIS Expansion trial showed uncertainty regarding the efficacy of the catheter- based approach, but the design of these studies had some limitations such as, a relatively long interval before intraarterial treatment, the absence of pretreatment vascular imaging to confirm a proximal intracranial occlusion, and the limited use of third-generation mechanical thrombectomy devices such as retrievable stents. Recently, Multicenter Randomized Clinical Trial of Endovascular Treatment for Acute Ischemic Stroke in the Netherlands (MR CLEAN) was conducted on 500 stroke patients and revealed that intraarterial treatment with or without intravenous alteplase was safe and more effective method in comparison to the intra venous alteplase alone, if done in patients with a proximal arterial occlusion in the anterior circulation within 6 hours after symptom onset (An absolute difference of 13.5 percentage points (95% CI, 5.9 to 21.2) in the rate of functional independence (modified Rankin score, 0 to 2) in favor of the intervention (32.6% vs. 19.1%) and no significant differences in mortality or the occurrence of symptomatic intracerebral hemorrhage). In our study we did 35 mechanical interventions that showed this route of therapy could be consider in acute stroke. 56 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 140 A clinical trial of effectiveness of the cerebrolysin drug in A cute ischemic stroke compression with control group hospitalized patients in Farshchian hospital in Hamadan Iran (2011-12) Mehrdokht Mazdeh, Sajede Nazari Farshchian Hospital of Hamadan, Hamadan, Iran BACKGROUND: Stroke is the third common cause of mortality and the most common neurologic disease resulting disability in the United States. Because the disability caused by this disease and its effects on the quality of life of the patients and economic burden, is an important health problem in the societies. Various treatments proposed for this disease that one of them is cerebrolysin administration. This agent stimulates cell differentiation, has direct effect of neurons' regeneration, reduce the infarct size area, reduce the apoptosis and oedama and stabilize blood circulation to involved area. The aim of this study was evaluating the therapeutic effect of cerebrolysin in patients with stroke. METHODS: In a randomized controlled trialed 122 patients with confirmed ischemic acute stroke enrolled to study. The patients divided to two groups, study and control group. The study group received 10 ml cerebrolysin in 100 ml saline as an infusion for 30 minutes daily during seven days and control group received only saline same by same way of the study group. All the patients evaluated at the days 1, 3, 7 and 30 for the CSS, MRS and Barthel Index for treatment results. The results analyzed by t- student test and chi-square test with the SPSS software. RESULTS: The mean of Canadian Stroke scale score at the day 7 increased about 59% in study group and about 42% in the control group (P>0.05). There was not significant differences between two groups in terms of subgroup different indices of CSS (GCS, tongue and physical functions) Barthel & MRS index (P>0.05). CONCLUSION: This study indicates cerebrolysin has not noticeable effect in the patients with acute Ischemic stroke. 57 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 141 Development of National guideline for diagnosis, treatment and follow up of stroke patients in Iran Kavian Ghandehari, Mohammad Reza Gheini, Mohammad Hossein Harirchian, Mohammad Hadi Modaghegh, Mahmood Farhoudi, Mahmood Reza Azarpazhooh, Payam Sasannezhad, Human Baharvahdat, Armin Shirvani, Rozita Davoodi, Golnaz Sabouri, Hoda Khoshmohabat Stroke Unit, Neurocognitive Research Center, Mashhad UMS, Iran National and international guidelines have been made for management of stroke patients in the word. These guidelines simplifies diagnosis, work up and management of stroke patients. Development of clinical guidelines is based on meta-analysis of numerous clinical trials by expert team. Stroke neurologists, neurosonologist, neuroradiologist, neurointerventionist, neurosurgen, and vascular surgeon consisted our team of experts. This guideline was conducted under supervision of executive evidence based medicine committee of Ministry of health and medical education of Iran in 2014. Funding budget of this guideline was provided by Mashhad University of Medical Sciences. Scientific committee analyzed level of evidence for each diagnostic and therapeutic intervention of ischemic and hemorrhagic stroke patients. Hyperacute, acute and chronic management of stroke as well as primary and secondary prevention of stroke was included in the guideline. Interventional, vascular surgical and neurosurgical managements are considered in the guideline protocol. This guideline was adjusted based on therapeutic condition and problems in Iran. Clinical data derived from stroke clinical studies in Iran, experience of our team members and numerous international stroke guidelines. The text of Iranian national stroke guideline is going to be published by Iranian Ministry of Health and Medical Education and will be distributed online. This guideline will be used by Iranian neurologists and stroke physicians. This is the first designed national stroke guideline in the Middle East and west of Asia. 58 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 142 Iranian cut off of HASBLED score in prediction of hemorrhagic complications in stroke patients with non-valvular atrial fibrillation receiving warfarin therapy Kavian Ghandehari, Mostafa Dastani, Siamak Yazdani, Mohammad Taghi Shakeri Stroke Unit, Neurocognitive Research Center, Mashhad UMS, Iran BACKGROUND: Atrial Fibrillation is the most common underlying cardioembolic cause of stroke. Taking an oral anticoagulation (Warfarin) is an effective therapeutic prevention of ischemic stroke in these patients but bleeding complications is common. HASBLED Criteria is used to predict hemorrhagic side effects. METHODS: In this cohort study we follow 112 patients with Non-Valvular atrial fibrillation in term of major and minor bleeding complications to assess the predictive value of HASBLED Criteria. Major bleeding complications defined as intracranial bleeding, bleeding leading to hospitalization, drop in hemoglobin of more than 2gr/dl or requiring blood transfusion. HASBLED score were defined as Hypertension, Liver and Renal dysfunction tests, History of Stroke, History of Bleeding, Large Fluctuations in Coagulation Tests, old age and an Anti-platelet and NSAID and Alcohol use 1 point is awarded to each of the above. RESULTS: During follow up period 10 (9.1%) of patients had major bleeding and 28(25%) patients had minor bleeding. The risk of major bleeding were significantly related to history of minor bleeding and HASBLED scores (p<0.001). The risk of minor bleeding with warfarin toxicity and High INR were significantly related (p<0.001). HASBLED Score higher than 3 with sensitivity of 70% and specificity of 80%was associated with the likelihood of major bleeding and scores higher than 2 were associated with likelihood of minor bleeding with sensitivity of 93% and specificity of 66%. CONCLUSION: Oral anticoagulant (warfarin) therapy in patients with HASBLED scores higher than 3 should be performed cautious. 59 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 143 Intracranial Angioplasty and Stenting for Cerebral Atherosclerosis Hamzehloo A Department of Interventional Neurology, Milad Hospital, Tehran, Iran Intracranial cerebral atherosclerosis causes ischemic stroke in a significant number of patients. Technological advances over the past 10 years have enabled endovascular treatment of intracranial atherosclerotic stenosis. The number of patients treated with angioplasty or stent-assisted angioplasty for this condition is increasing. This article was written under the following of cases which performed in my hospital in one year. 60 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 144 Carotid artery intima-media thickness and opium addiction Saadatnia M, Ebrahimi H Isfahan University of Medical Sciences, Isfahan, Iran BACKGROUND: Despite some evidences about protective or triggering role of opium use in patients with coronary artery disease, the exact role of opium is still under question and there is no study to show the effect of opium on intima media thickness (IMT). The current study aimed to address the relation of opium addiction on IMT. METHODS: This cross-sectional study was performed on subjects referred to neurovascular clinic. All the subjects underwent cerebrovascular ultrasound and Carotid artery IMT was assessed. A questionnaire containing demographic data, opium use information [based on the 4th Edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) criteria], and vascular ultrasound findings were completed for each subject and the results were analyzed using regression test. RESULTS: In this study, 285subjects were included. Twenty two (7.7 %) subjects were addicted to opium and the remaining were non-addicts. After multiple regression analysis, including age, sex, body mass index, hypertension, diabetes, smoking, hyperlipidemia and opium addiction, carotid artery IMT remained significantly associated with age, hypertension, diabetes, and smoking and opium addiction was not significantly associated with IMT (P=0.00, P=0.09, P=0.06, P=0.09, P= 0.64). CONCLUSION: Opium addiction have no role in carotid IMT, one possible explanation for this finding is that narcotics may decrease inflammation, which is directly associated with atherogenesis and plaque disruption. 61 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 145 Can HTLV-1 infection be a potential risk factor for carotid artery atherosclerosis? Ali Shoeibi, Parvaneh Layegh, Ali Ghabeli Juibary, Sahar Darbarpanah, Mahmoudreza Azarpazhooh School of Medicine, Mashhad University of Medical Sciences, Mashhad, Iran BACKGROUND: Chronic inflammation and infectious diseases such as HIV infection are now considered as risk factors for atherosclerosis. In this study, for the first time, Human T-lymphotropic virus type-1 (HTLV-1) infection is examined as a potential risk factor for atherosclerosis. METHODS: This is a match pair cross sectional study on fifty-eight HTLV1 infected cases and 55 healthy control subjects. The subjects did not have any major cerebrovascular risk factors. Carotid IMT (intimamedia thickness) was measured for each patient using the standard protocol of the Atherosclerosis Risk in Communities (ARIC) Study. RESULTS: The mean age of our subjects was 42.9±10.52 years and males made up 33% of the population. The difference between mean IMT of infected case group and healthy control group was significant (P<0.05). Discussion: This study indicated that HTLV-infected patients had greater carotid IMT compared with age- and sex-matched control subjects. CONCLUSION: Having no other known risk factor for atherosclerosis, we concluded that significant difference of IMT in our patients might support this hypothesis that HTLV1 infection is an independent risk factor for atherogenesis. 62 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 146 Cost-Effectiveness Analysis of the Unfractionated Heparin versus Low Molecular Weight Heparin in Hospitalized Patients with Stroke due to Atrial Fibrillation in Shiraz, South of Iran 2013 Bahmehei A, Hatam N, Sedghi R, Feiz F, Borhani-Haghighi A Shiraz University of Medical Sciences, Shiraz, Iran BACKGROUND: Patients with Atrial Fibrillation (AF) make a unique group of stroke. Unfractionated Heparin (UFH) and Low Molecular Weight Heparin (LMWH) are among medications that used by physicians for prevent of blood coagulation. The present study was done with purpose the costeffectiveness analysis of LMWH versus UFH in hospitalized patients with stroke due to AF from Iran’s society perspective. METHODS: In this study decision tree model was used. Costs data were collected through interviews with patients with stroke due to AF and their companions with using of data collection form including the medical direct costs, non-medical direct costs and indirect costs, three months after the medications injection. Effectiveness criterion was prevention of new stroke recurrence. Therefor results of this study were expressed as cost per new stroke prevention. Finally a one-way and probabilistic sensitivity analysis was conducted to examine the strength of the results. RESULTS: Our analysis results showed that effectiveness based on prevention of new stroke by LMWH more than UFH. Also UFH medical direct costs, non-medical direct costs and also indirect cost was more than LMWH. Cost-effectiveness ratio estimated - 150, 201, 26$ per each effectiveness. CONCLUSION: The results of the cost–effectiveness analysis of LMWH versus UFH showed that, LMWH is a dominant strategy for patients with stroke due to AF from Iran’s society perspective. 63 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 147 The prevalence and factors contributing to hemodynamic depression in patients undergoing carotid angioplasty and stenting Afshin Borhani Haghighi1,2, Safoora Kokabi2, Samaneh Yousefi3, Mehrdad Emami4, Abdolhamid Shariat1,2, Alireza Nikseresht1,2, Nahid Ashjazadeh1,2, Sadegh Izadi1,2, Peyman Petramfar1,2, Maryam Poursadegh1,2, Abbas Rahimi Jaberi1,2, Sajjad Emami5, Hamid Agheli6, Reza Nemati7, Ehsan Yaghoubi8, Mohammad Hosein Abdi9, Majid Panahandeh10, Seyed Moslem Heidari- Khormizi11, Salvador Cruz-Flores12, Randal Edgell13 1-Clinical Neurology Research Center, Shiraz University of Medical Sciences, Shiraz, Iran 2-Departments of Neurology, Shiraz University of Medical Sciences, Shiraz, Iran 3-Student research Committee, Fasa University of Medical Sciences, Shiraz, Iran 4-Transgenic Technology Research Center, Shiraz University of Medical Sciences, Shiraz, Iran 5-Department of Neurology, Faculty of Medicine, Jahrom University of Medical Sciences, Jahrom, Iran 6-Shahidzadeh Hospital, Behbahan, Iran 7-Department of Neurology, Faculty of Medicine, Bushehr University of Medical Sciences, Bushehr, Iran 8-Department of Neurology, Faculty of Medicine, Yasuj University of Medical Sciences, Yasuj, Iran 9-Motaharri Hospital, Marvdasht, Iran 10-Ordibehesht Hospital, Shiraz, Iran 11-Department of Neurology, Faculty of Medicine, Rafsanjan University of Medical Sciences, Rafsanjan, Iran 12-Departments of Neurology, Texas Tech University, El Paso, USA 13-Departments of Neurology and Psychiatry, Saint Louis University, Saint Louis, USA BACKGROUND: Hemodynamic depression including bradycardia and hypotension are among the most common complications of carotid angioplasty and stenting. METHODS: A prospective, cross-sectional study was conducted at Shiraz University of Medical Sciences in southern Iran from 2011 to 2013. Consecutive patients undergoing carotid angioplasty and stenting were included. Demographic data, atherosclerotic risk factors, pre-procedural blood pressure, site of stenosis, degree of stenosis, and data regarding technical factors were recorded. Hemodynamic depression was defined as a systolic blood pressure less than 90 mmHg and/or heart rate less than 50 beat/min. RESULTS: Totally, 170 patients (67% male, mean age: 71+9.8, 55.9% right side, 82.9% symptomatic) were recruited. Mean degree of stenosis was 79.4% in operated side and 40.7% in non-operated side. Predilation, post dilation, or both were conducted in 18 (10.5%), 141 (83%), 11 (6.5%) patients respectively. Thirteen (7.6%), 41 (24%), and 12 (7%) of patients developed post-procedural bradycardia, hypotension or both, respectively. Two patients had a stroke after CAS and peri-procedural mortality was 0%. Hemodynamic depression after CAS had a significant association with pre-procedure blood pressure and the use of an open cell stent design, but not with atherosclerotic risk factors, site and/or degree of stenosis, predialtion, or postdilation. Hemodynamic depression significantly increased hospital stay too. CONCLUSION: Pre-procedural hydration and close-cell stents may decrease the risk of post-stenting hemodynamic depression. 64 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 148 Correlation between Dysphagia and nutritional indicators in ischemic stroke patients at the time of hospital admission Fatemeh Seifar, Mohamad Khalili 1-Students research committee, Neurosciences Research Center, Tabriz University of Medical Sciences, Tabriz, Iran 2-Neuroscience Research Center, Tabriz University of Medical Science, Tabriz, Iran BACKGROUND: Dysphagia and poor nutritional status are common complications of stroke. However, possible associations between them are not well understood. Furthermore, it is necessary to perform a nutritional assessment of the patient in the early hours of admission, to determine both the nutritional status and the presence of dysphagia. So in this study, potential associations between dysphagia and nutritional indicators in patients with acute ischemic stroke at the time of hospital admission were evaluated. METHODS: In this observational cross-sectional study, patients with ischemic stroke admitted to academic medical centers were enrolled. We studied 30 patients with stroke at the time of admission. The frequency of dysphagia and dysphasia grading score was evaluated. Nutritional indicators were assessed by knee height, mid arm circumference, triceps skin fold thickness, and calf circumference of all the admitted patients. The possible correlation between dysphagia and each parameter was evaluated. RESULTS: On clinical assessments 73.33% of patients demonstrated dysphagia. Dysphagia, was significantly associated with lower calf circumference (P<0.05), but not with other nutritional indicators (knee height, mid arm circumference, triceps skin fold thickness). CONCLUSION: Dysphasia is a prevalent problem in patients with acute ischemic stroke, however, in overall view was not associated with major nutritional failure at the time of hospital admission. 65 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 149 Gerstmann’s syndrome in non- dominant hemisphere involvement Masoud Ghiasian, Mojtaba Khazaee, Mehrdokht Mazdeh, ElaheRaisi Rad Department of Neurology, Hamadan University of Medical Sciences and Health Services, Hamadan, Iran Gerstmann’s syndrome is caused by a left (dominant) inferior parietal lesion, particularly involving the angular gyrus or subjacent white matter of the left hemisphere. The characteristic tetrad is finger agnosia, confusion of the right and left side of body, acalculia and dysgraphia. Our patient was an 80-year-old right handed man with sudden onset of blurred vision. In neurological examination, he had left homonymous hemianopia and characteristic features of Gerstmann’s syndrome. CT scan showed hypo dense area in right occipital lobe with expansion to parietal and temporal lobe. 66 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 150 Determining level of blood pressure in patients with acute stroke in Farshchian hospital of Hamadan, in 2013-2014 Khazaei M, Mazdeh M, Ghiasian M Farshchian Hospital of Hamadan, Hamadan University, Hamadan, Iran BACKGROUND: Stroke or cerebrovascular accidents are the third leading cause of mortality and the most important cause of morbidity in adults in the most of the world. Multiple factors such as socioeconomic conditions, life style, risk factor, genetic and environmental factors may be the causes of stoke risk differences in different societies. This study, the level of blood pressure of acute stroke patients was investigated. METHODS: In cross-sectional study, all patients with diagnosis of stroke in Farshchian hospital that were admitted from March 2012 through March 2013. Their demographic data were recorded including (age, gender), blood pressure in the acute phase and the time of discharge, history of diabetes, hyperlipidemia and heart disease. RESULTS: The frequency of male and female was 54% and 46% and average of age them was 65.89 and 72.67. Ischemic stroke was higher than others (65%). In 33.67% of patients before admission hospital received or Hydralazine or nitroglycerin. Mean systolic and diastolic blood pressure in patients on admitted were 154.64 mm 92.97 mm Hg respectively. Among them 60.22% of the patients have recovered, 24.78% of the patients have expired and 10.11% have remained unchanged and 4.89% has deteriorated. CONCLUSION: Nearly 83% of the stroke patient used regulatory drugs of blood pressure that showed the important role of hypertension in the stroke. Blood pressure in the stage of stroke acute is increased and in the first 48 hours after the garlic bed that the average of blood pressure in the patient with a history of hypertension was higher than normal groups. 67 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 151 Prevalence of atrial fibrillation rhythm in patients with stroke admitted to Farshchian hospital in the second half of 2011 Mazdeh M, Khazaei M, Ghiasian M Farshchian Hospital of Hamadan, Hamadan University, Hamadan, Iran BACKGROUND: It has been reported that the prevalence of stroke is approximately 750,000 per year. The role of atrial fibrillation (AF) rhythm as one of important risk factors for stroke has been demonstrated. In the present study, the relationship between AF rhythm and cause of stroke was investigated. Methods: This cross-sectional study was performed among patients (n=460) that admitted from October through March 2011 in the stroke center at Farshchian hospital in Hamadan, Iran. The relationship between stroke, AF rhythm and some related risk factors were evaluated. RESULTS: In this study 52.5% of patients were female and 70.7% had ischemic stroke. The frequency of AF rhythm was 20.7%. Average age of patients with and without AF rhythm was 85.72 and 78.68 years (Min=60, Max=94), respectively (P<0.05). 19.3% of men and 21.59% of women have AF rhythm. CONCLUSION: There was no significant difference in the frequency of AF rhythm between men and women. In this study the frequency of AF rhythm in stroke patients was 20.7%. 68 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 152 Thrombosis of the Cerebral Veins and Sinuses: Clinical Presentation, Predisposing Factors and Outcome in Hamadan, West of Iran Masoud Ghiasian, Maryam Mansour Hamadan University of Medical Sciences and Health Services, Hamadan, Iran BACKGROUND: Cerebral venous sinuses thrombosis (CVST) is an uncommon type of stroke and is difficult to diagnose. Objectives: To describe the clinical presentation, predisposing factors, neuroimaging findings, and outcomes of the disease in Sina hospital in Hamadan, west of Iran. METHODS: This is a prospective study of patients presenting to emergency department of Sina hospital between May of 2011 to June of 2014 who were diagnosed with CVST. RESULTS: Eighty patients were included in this study. Median age was 39 (Mean: 39.30±11.66, Range: 15-72) years. There were 63 (78.8%) women and 17 (21.3%) men. Mean age of women and men were 38.35±10.41 and 42.82±15.33, respectively. The female to male ratio was 3.70. The most common presenting features were headache (78.8%), focal motor deficit (41.4%), mental status changes (35.0%), papilledema (32.5%), blurred vision (18.8%) and seizure (18.8%). The mean age of patients presenting with headache was 38.0±10.96. The most common risk factors in our patients were oral contraceptives (47.5%), dehydration (22.5%) and hypercoagulable state (16.3%). Twenty four patients (30%) had two and 2 patients (2.5%) had three risk factors simultaneously. Overall mortality was 13.8% (11 patients). After 6 months follow up 70.51% were functionally independent (mRS score 0-1). 15.38% were dependent. CONCLUSION: In our study the most common clinical presentation was headache. Every patient presenting with headache to emergency departments, especially young women with recent history of oral contraceptive consumption should be examined carefully. It seems fasting and its subsequent dehydration in women with recent use of oral contraceptives makes them more susceptible to CVST. Septic CVST had higher mortality than aseptic CVST. 69 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 153 Success and complication rates of carotid stenting in 500 cases Behnam Mansouri, Mohammd Karimi Imam Husain Hospital, Shahid Beheshti University of Medical Sciences, Tehran, Iran Carotid artery stenting is a procedure in which an interventionist inserts a slender, metal-mesh tube, called a stent, which expands inside the carotid artery. In this study we are reporting the result of our carotid stenting success and complications during past 5 years of intervention for carotid in two large centers of stroke and carotid stenosis investigation and angiography and carotid stenting. Average complication is generally 4 to 8% for severe neurologic complications patients (including death, major stroke, minor strokes) and short lasting neurologic deficits in additional 4-8% of patients. Cardiovascular complications are rare. Local (inguinal) problems occurred in average 2-4% patients. Frequently, balloon inflation was associated with bradycardia and additional hypotension. In our study average rate of complication was less than international rates which will be discussed in details in presentation. Also complications will be discussed. 70 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 154 Successful thrombectomy after failure of intra-arterial thrombolysis with rTPA: A case report Mohammad Reza Sobhani, Human Baharvahdat, Payam Sasanezhad, Kavian Ghandehari, Mohammad Mousavi Mirzaei Mashhad University of Medical Sciences, Mashhad, Iran CASE PRESENTATION: A 56-year-old woman, who was known case of DM, HTN, IHD, and Hlp was admitted in CCU of Ghaem hospital for acute MI and received intravenous heparin for first two days. On fourth day of admission, she suddenly developed left hemiplegia and left gaze paresis. An infarction was seen at right inferior MCA territory on the urgent brain MRI taken in the first hours. Initial modified NIHSS and ASPECT was 9 and 7, respectively. Acute MI was considered as exclusion criteria of intravenous thrombolysis with rTPA. She was transferred to neuroangiography unit and underwent intraarterial thrombolysis with 20 mg of rTPA at 5 hour after symptoms onset. However, control angiography after injection of rTPA showed no change in vessel lumen and patient assumed as failure of intra-arterial thrombolysis. Interventional thrombectomy with Solitaire device was performed immediately. Vasospasm was observed on right MCA branches and intra-arterial Nimodipine served for treatment of vasospasm subsequently. Administration of Plavix and ASA was initiated 24 hours after interventional therapy. The modified NIHSS changed to 4 after 24 hours and to 3 at 72 hours after intervention. CONCLUSION: Intra-arterial thrombectomy is a novel interventional management of hyperacute stroke and could be considered in patients whom are not candidate for intravenous thrombolysis with rTPA. 71 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 155 Evaluation of predictive value of ABCD2F score for recurrence of ischemic stroke or transient ischemic attack within the first 90 days Mostafa Almasi Dooghae1, Nader Hojjati Firoozabadi2, Mojtaba Chardoli2 1-Department of Neurology, Iran University of Medical Science, Tehran, Iran 2-Department of Emergency Medicine, Iran University of Medical Science, Tehran, Iran BACKGROUND: Stroke is a relatively common disease and has a high disease burden. The prediction of recurrence rate of transient ischemic attack (TIA) or ischemic stroke (IS) is helpful in the health management of such patients. Because of major value of atrial fibrillation (AF) in IS and TIA, we evaluated the predictive value of ABCD2F score for recurrence of IS or TIA within the first 90 days. METHODS: In this cross-sectional study, 138 patients of Rasool-Akram and Sina hospitals of Tehran with diagnosis of IS or TIA, from 1391 to 1392 were included. For each patient a check list composing different demographic and clinical variables were completed. ABCD2F score was calculated by adding 1 score for detecting AF to ABCD2 score. Then they were followed up for recurrence of IS or TIA within the first 90 days after event. Finally the data collected, coded and analyzed by 18th edition of SPSS software. RESULTS: 106 (76.8%) patients had IS and 32 patients (23.2%) had TIA. Thirteen patients (9.42%) conducted another stroke or TIA within 90 days. The mean ABCD2 and ABCD2F score, in patients with recurrent stroke were 4.61±0.50 and 4.77±0.54; and in patients without recurrent stroke were 5.06±0.12 and 5.11±0.12, respectively. These differences were not statistically significant (P=0.421 for ABCD2 score and P=0.557 for ABCD2F score). The detection of AF rhythm was associated with greater stroke recurrence rate but it was not statistically significant (P=0.232). Among other variables, just positive history for ischemic heart disease, no prescribing of aspirin on discharge and platelet count were statically relevant with recurrence of stroke. CONCLUSION: ABCD2F score, like ABCD2 score, cannot predict the recurrence of IS or TIA within the first 90 days after event and another criterion for the prediction of stroke is needed. Therefore further studies and taking into account variables such as a history of ischemic heart disease, drug history and coagulation laboratory tests are recommended. 72 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 156 Assessment of admission platelet level and age, in responsiveness to Aspirin in ischemic stroke patients: one year follow up Mostafa Almasi Dooghaee1, Sadegh Rahimi2, Farzan Falahat3, Mehdi Moqaddasi1 1-Department of Neurology, Iran University of Medical Science, Tehran, Iran 2-Mashhad University of Medical Science, Tehran, Iran 3-Iran University of Science and Technology, Tehran, Iran BACKGROUND: Stroke is seated in the first rank of leading cause disability worldwide. Aspirin inhibit the platelet aggregation and were used as secondary preventing in ischemic stroke. The aim of present study is evaluating possible impact of patient platelet level, age and sex on Aspirin efficacy for preventing recurrent stroke or TIA. METHODS: A retrospective cohort study conducted on the patient with ischemic stroke of TIA whom admitted in Rasul-e-Akram Hospital of Tehran, Iran, during 2013. All data including demographic variables and clinical profile on admission and discharge time were recorded in a checklist for each patient. After three months to one year of admission, all patients have been called by expert for follow-up about the symptoms of renewed TIA or stroke and other problems. The exclusion criteria were previous consumption of antiplatelet before stroke event, discharge with prescription of other anticoagulants except alone Aspirin, and lack of follow-up data. Finally four balanced age group composing under 55, 5570, 70-80, and over 80 years were defined. For analysis, SPSS edition 16th statistical software and the C5 decision tree is used. RESULTS: From 231 patients diagnosed as ischemic stroke, 122 patients (88%) met the criteria. On follow up, 2.60% reported renew Stroke, 4.60% renew TIA and 6.49% admitted to hospital due to vascular diseases. In 4 age groups, mean±SD of admission platelet level were 226.255±60.5, 228.39±79.8, 202.17±68.3 and 199.55±67.4, respectively. Base on C5 decision tree, Aspirin had no significant effect on patients over 80 years with platelet below 155/mm3 (p<0.001 according to Cochran–Mantel–Haenszel test). This result was not banded to patient’s gender. CONCLUSION: On follow up of the patients with ischemic stroke or TIA, we found that Aspirin had no significant effect on patients over 80 years with platelet below 155/mm 3. For substitution of Aspirin with another medication in these patients, more studies are required. 73 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 157 Cerebral Venous Trombosis or Idiopathic Intracranial Hypertension, Spectrum of Findings and Diagnostic Pitfalls Sheida Shaafi, Masoud Nikanfar, Dariush Savadi, Maziar Hashemilar, Safa Najmi, Saeed Charsoei Tabriz University of Medical Science, Tabriz, Iran Dural sinus hypertension from cerebral venous outflow impairment is a cause of pseudo tumor cerebri. On the other hand cerebral venous thrombosis is a relatively uncommon but serious neurologic disorder that is potentially reversible with prompt diagnosis and appropriate medical care. Because the possible causal factors and clinical manifestations of this disorder are many and varied, imaging plays a primary role in the diagnosis. Magnetic resonance (MR) imaging, un-enhanced computed tomography (CT), unenhanced time-of-flight MR venography, and contrast material-enhanced MR venography and CT venography are particularly useful techniques for detecting cerebral venous and brain parenchymal changes that may be related to thrombosis. To achieve an accurate diagnosis, it is important to have a detailed knowledge of the normal venous anatomy and variants, the spectrum of findings (venous sinus thrombi and recanalization, parenchymal diffusion or perfusion changes or hemorrhage), other potentially relevant conditions (deep venous occlusion, isolated cortical venous thrombosis, idiopathic intracranial hypertension), and potential pitfalls in image interpretation. Our aim of this study is to clarify most challengeable issues in this fact while clinical and imaging evidences are sufficient for diagnosis, but the management is very different. More than 100 causes of venous thrombosis have been described in the literature. Causal factors may be classified as local (related to intrinsic or mechanical conditions of the cerebral veins and dural sinuses) or systemic (related to clinical conditions that promote thrombosis). In 25% of cases, no cause is identified. The clinical manifestations of cerebral venous thrombosis vary, depending on the extent, location, and acuity of the venous thrombotic process as well as the adequacy of venous collateral circulation. Generalized neurologic symptoms (e.g., headache, experienced by 75%– 95% of patients) and focal neurologic deficits, including seizure may result. Focal neurologic symptoms are more often seen in patients with parenchymal changes observed at imaging than in those without such changes. Because thrombosis and endogenous thrombolysis and recanalization may occur concurrently, the clinical manifestations may fluctuate in as many as 70% of patients, adding to clinical uncertainty. Intracranial hypertension occurs in 20%–40% of patients with cerebral venous thrombosis and should be excluded in patients with the specific complex of symptoms. MRI combined with MRV examination is the preferred method of diagnosing CVST. A review of the MRI literature published in recent 10 years enables a general description of the anatomic distribution of thrombosed cerebral venous structures identified primarily at MRI. 74 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 158 Validation of HAS_BLED score in prediction of hemorrhagic complications in patients with brain ischemia and atrial fibrillation receiving warfarin therapy Siamak Yazdani, Kavian Ghandehari Sajjadieh Hospital, Torbat Jam, Iran BACKGROUND: Cardioembolic strokes are responsible for 20 percent of ischemic stroke cases. It happens due to atrial fibrillation (AF) in most patients. Although oral anticoagulant administration is a reliable method which could prevent ischemic stroke, hemorrhagic events are the most common complication of anticoagulants. The aim of this study was the use of HESBLED scoring system in predicting hemorrhagic events. METHODS: after ethical approval, a cohort study was designed with 112 patients with AF who used warfarin. Patients were followed up for one year period. Hemorrhagic events were classified as major and minor hemorrhage. Data was analyzed by SPSS version 16 with parametric and nonparametric tests. RESULTS: Ten patients (9%) had major hemorrhage and 28 patients (25%) had minor hemorrhage. Major hemorrhage was associated with minor hemorrhage and HESBLED score (P<0.0001). Minor hemorrhage related to high INR and warfarin toxicity (P<0.0001). Sensitivity and specificity of HESBLED more than 3 for predicting hemorrhagic events was 70% and 86%, respectively and associated with probable major hemorrhage, HESBLED more than 2 was associated with future minor hemorrhage. CONCLUSION: Our study demonstrated that patients who have HESBLED score higher than 3 and have indications for anticoagulant therapy and have history of minor hemorrhage and warfarin toxicity history should be observed closely. 75 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 159 Cerebral Venous-Sinus Thrombosis: Risk Factors, Clinical Report, and Outcome a Prospective Study in North Eastern Iran Siamak Yazdani Neurologist, Mohammad Taghi Farzadfar, Ali Ghabeli Juibari Sajjadieh Hospital, Torbat Jam, Iran PURPOSE: We undertook this prospective study to determine the demographic, clinical patterns, etiologies and prognostic factors of cerebral venous-Sinus thrombosis (CVST) in North Eastern Iran. METHODS: All adult patients admitted with an angiographically documented diagnosis of cerebral venous thrombosis from 2011 through 2012 in Ghaem hospital, Mashhad University of medical sciences in north eastern Iran, were entered the study. RESULTS: Sixty patients (8 men, 52 women) aged 18 to 83 years were identified. Fifty one cases (85%) had a clinical picture of pseudo tumor cerebri. Causes included antiphospholipid antibodies in 3.3%, protein C, S and anti thrombin III deficiency in 5%,1.7% and 3.3%, polycythemia in 1.7%, infections in 1.7%, postpartum in 9.6% of women, and oral contraceptives in 65.38%. We found a 10% mortality rate on discharge and 11.9 % within 30 days 42.7% rate of death or dependency at month 6 and 12. CONCLUSION: The findings of the study indicate that the use of OCPs was a main factor associated with CVST. This study demonstrates that screening for inherited hypercoagulable state should be an essential part in the diagnostic work up of CVT patients. Among patients with early intracerebral hemorrhage or stupor on admission were at higher risk for death or dependency at month 6 and 12. 76 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 160 Anterior Communicating Artery Aneurysm, 6 years follow up of A-com aneurysm coiling in Milad Hospital Karimi M, Hamzehloo A, Zandi P, Jalali A, Manteghi RF, Arami MA, Mansouri B Milad Hospital, Tehran, Iran BACKGROUND: Aneurysmal Subarachnoid Hemorrhage (SAH) is a devastating and often fatal form of stroke. The aneurysm is targeted for obliteration to prevent re-bleeding and to manage the possible complications from the event. New methods of endovascular coiling have emerged as a less invasive alternative to conventional surgical clipping to treat aneurysms. METHODS: This study was done prospectively in the Milad hospitals to evaluate the outcome of different methods of endovascular coiling and we followed up them for 6 years. RESULTS: Complications including hydrocephalus, hemiparesis and failed procedures occurred in (3.7%). CONCLUSION: We concluded that coiling is better for treating cases of ruptured A-com aneurysms being less invasive and achieving a favorable outcome compared to surgery. 77 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 161 Oral contraceptive-related cerebral venous thrombosis as an initial manifestation of antiphospholipid syndrome in the absence of systemic lupus erythematosus Payam Saadat1, Reza Mohseni Ahangar2 Department of Neurology, Babol University of Medical Sciences, Babol, Iran Department of Internal Medicine, Babol University of Medical Sciences, Babol, Iran BACKGROUND: Cerebral venous sinus thrombosis is a rare and potentially life-threatening neurologic manifestation of antiphospholipid syndrome. Oral contraceptive pills may increase the risk of vascular events, even in people without family history of venous thrombosis. CASE PRESENTATION: A 31-year-old woman presented with four weeks of constant headache. She had a history of taking OCP for one year. The results of brain magnetic resonance imaging and venography confirmed a diagnosis of cerebral venous sinus thrombosis. The serum anticardiolipin and antiphospholipid antibodies were elevated and a definitive diagnosis of antiphospholipid syndrome was made. CONCLUSION: The present report demonstrates the importance of screening for antiphospholipid antibodies in patients presenting with cerebral venous sinus thrombosis, despite history of taking OCP. 78 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 162 The effect of levodopa on motor function outcome in patients with ischemic stroke: A double-blind, placebo-controlled, randomized clinical trial Zandifar S¹, Shamsaei GR¹, Hassanzade AR¹, Nakhostin- Mortazavi A¹, Safapour N² 1-Department of Neurology, Ahvaz Jundishapur University of Medical, Ahvaz, Iran Science 2-Department of Internal Medicine, Ahvaz Jundishapur University of Medical Science, Ahvaz, Iran BACKGROUND: Levodopa increases neuronal plasticity and anatomical and functional changes in the central nervous system and enhances functional recovery. PURPOSE: To evaluate the effect of levodopa on motor function recovery of patients after a stroke. METHODS: This was a double blinded, randomized, placebo-controlled trial to compare the effects of levodopa-C dose of 100 mg daily versus placebo for 3 weeks. 114 patients with ischemic stroke in the middle cerebral artery stroke after the first day, levodopa and placebo were randomly assigned to two groups. They received the stroke routine medications during the study. RESULTS: Finally, 113 patients (57 patients in the levodopa group and 56 patients in the placebo group) completed the study. A significant difference was seen in terms of improvement of motor function in criteria of RMI (p=0.006) and BI (p=0.009) after 21 days in levodopa-C (79.1%) compared to the placebo group (49%). A review was carried in the subgroups, which indicate that patients with cortical stroke in the levodopa group had a significant improvement compared with the placebo group (p=0.005). Approximately 79% of patients (n=35) in levodopa-C group, mostly in the cortical stroke, obtained more than 25% their basic motor function on the basis of criteria BI and RMI while the rate in the placebo group was 44% (eight persons) (p=0.008). CONCLUSION: The promising results of the efficiency of levodopa-C were observed in the subgroup of patients with cortical stroke. Larger clinical studies involving larger numbers of patients with cortical ischemic stroke is needed to better assess the impact. 79 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 163 The association of seasonal and weather changes with the incidence of stroke in Zanjan Valiasr Hospital Golipoor F, Eshghi A Zanjan University of Medical Sciences, Zanjan, Iran BACKGROUND: Stroke is the second cause of death and the third reason for urological disability worldwide. Recent studies suggest seasonal and climate changes as being involved in the incidence of stroke. However, the overall outcome of such studies is not conclusive and no similar study so far has been conducted in Iran. In the present study we aimed at investigating the seasonal and weather variations in the incidence of stroke in Valiasr Hospital in Zanjan city, Iran. METHODS: Patients admitted to the Valiasr Hospital with a firm diagnosis of a recent stroke during 20102013 were included in the study. ICD-10 coding system for classification of disease was used to extract the relevant information form the electronic archive of the hospital. Chi-square test was used to examine the independence in the seasonal outbreak of stroke. Negative bi nominal regression modeling was performed to test the relationship between the incidence of stroke and air temperature. RESULTS: Totally, 6636 patients were included in the study. A significant monthly/seasonal difference was observed in a 3-year period (p-value<0.05), whereas the differences were not statistically significant when each year was considered, separately. The highest 3-year incidence of stroke was found to be in spring (April) while the incidence was the lowest in the fall (December). No significant relationship was found between the air temperature and outbreak of stroke. CONCLUSION: We were able to show a significant difference in the incidence of stroke by seasons. The weather changes, however, could not justify our observations. This calls for further research to investigate the non-climate predictors of seasonal variations in the incidence of stroke. 80 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 164 A Comparative Study of Low-Molecular-Weight Heparin with Unfractionated Heparin in Treatment of Cerebral Venous Sinus Thrombosis Randomized controlled trial Daryoush Afshari, Nasrin Moradian, Freshteh Nasiri, Arash Bostani, Nazanin Razazian Kermanshah University of Medical Science, Kermanshah, Iran BACKGROUND: There is small randomized controlled trial for comparison of efficacy and safety of LowMolecular-Weight Heparin (LMWH) and Unfractionated Heparin (UFH) in treatment of cerebral venous sinus thrombosis. PURPOSE: In current study, we have compared two kinds of heparin and their effect on mortality, severity of disability and neurologic deficits in treatment of cerebral venous sinus thrombosis (CVST). METHODS: Our study was performed as a randomized double-blind clinical trial in 2013-2014. Fifty two cases of cerebral venous sinus thrombosis, confirmed by brain MRI and MR venography, were included in this study and randomly divided into two groups with similar demographic, clinical, and radiological characteristics. Twenty six cases received LMWH and the other 26 cases received UFH for 7 days after which 8 cases were excluded from the latter group due to loss to follow-up or transferring to other centers. Mortality rate, neurologic deficit, and severity of disability of each group are assessed by National Institute of Stroke Scale (NIHSS) and Modified Rankin Scale (MRS). RESULTS: One patient died in each group, while, after one month, we observed no significant difference in the rate of neurological deficits based on NIHSS (p value=0.76) and severity of disability (MRS) (p value=0.95) between two groups. CONCLUSION: This study showed that efficacy of LMWH and UFH was similar and there is no difference in mortality rate between two types of treatments. 81 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 165 New Oral Anticoagulants for Stroke Prevention in Atrial Fibrillation Behnam Safarpour Lima1, Khosro Jamebozorgi2 1-Department of Neurology, Imam Hossein Hospital, Shahid Beheshti University of Medical Sciences, Tehran, Iran 2-Department of Neurology, Zabol University of Medical Sciences, Zabol, Iran Vitamin K antagonists such as warfarin have historically been used to reduce the risk of stroke in patients with atrial fibrillation as the only oral anticoagulants for decades. Atrial Fibrillation is responsible for 15% of strokes in people of all ages and 30% in people over 80. Traditionally, warfarin has been the anticoagulant of choice in these patients and has been shown to significantly reduce the risk of stroke. Warfarin, however, is difficult to manage as it requires frequent laboratory monitoring and has multiple interactions with common foods and drugs. Furthermore, many people receiving warfarin therapy still have inadequate anticoagulation. Therefore, there is a significant need for new oral anticoagulants that are safe, effective, and convenient to use. Direct thrombin inhibitors and factor Xa inhibitors are new anticoagulants recently approved for prevention of stroke in patients with AF. As medical providers, it is important to be familiar with the pharmacology of these new oral anticoagulants, indications for their use, and reversal therapy in the setting of major hemorrhage. The aim of this article was to provide a systematic review of recently published clinical data on the direct thrombin inhibitors and factor Xa inhibitors in the management of AF. 82 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 166 Glycated hemoglobin in acute strokes Alireza Vakilian1, Amir Moghadam Ahmadi2, Moslem Heidari3, Marjan Saeedinezhad4 1-Geriatric Care Research Center, Rafsanjan University of Medical Sciences, Rafsanjan, Iran 2-Clinical Research Development Center, Ali- Ebn Abitaleb Hospital, Rafsanjan University of Medical Sciences, Rafsanjan, Iran BACKGROUND: Stroke is considered as the most common and most fatal neurologic condition. Some studies have indicated the prognostic value of glycated hemoglobin (HbA1c) serum level in patients with stroke. The current study aims measuring the HbA1c serum level in patients with ischemic stroke and intracranial hemorrhage (ICH) and determining its relationship with the extent and severity of these lesions. METHODS: 120 stroke patients were studied with aspect of their HbA1c serum levels during the first 72 hours after their admission. They were classified into two groups, ischemic and hemorrhagic, base on imaging data. The extent of lesions was measured separately in both groups. Severity of lesions also was determined with Modified Rankin Scale (MRS). Data were analyzed using the SPSS 18 and Anova and T test. RESULTS: In our study, 49 male (40.8%) and 71 female (59.2%) patients were studied. The average age was 72.03 years. Fifty eight patients were diabetic. Level of HbA1c was significantly higher in ischemic stroke patients than hemorrhagic ones (P<0.005). Although the level of HbA1c was higher in major ischemic stroke group than minor ones, we did not find any correlation between severity and HbA1c. The level of HbA1c with extent and severity of hemorrhagic lesion had inverse non-significant relationship. The only finding identified between level of HbA1c and other stroke causing-factors was higher level of it, in hypertensive ICH patients (p=0.04). CONCLUSION: These findings revealed that increased level of HbA1c in patients with ischemic stroke can point to great role of diabetes in this type of stroke. We also found a relative inverse correlation between this hemoglobin and the extent of hemorrhagic lesions. 83 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 167 Investigation of family history among patients with stroke in Tohid Hospital of Sanandaj between 2013 and 2014 Payam Khomand, Amir Ghaba sia, Ghobad Moradi, Behrooz Ahsan Kurdistan University Medical Sciences, Kurdistan, Iran BACKGROUND: The high prevalence of stroke and increased rates of its morbidity and mortality, necessitate the importance of known related risk factors. Most of the risk factors are known and some have been controlled such as hypertension, diabetes. However, some of them are still unknown or their importance has not been completely assessed. Family history is considered as an independent factor in some references, but there is some controversy surrounding investigations about its effects. METHODS: This is descriptive cross-sectional study study. Cases are selected subsequently during 12 months from the patients who were admitted in the Tohid Hospital of Sanandaj. Family history of stroke (in first-degree relatives) and other existing risk factors were compared in 100 patients with stroke and 100 controls in other wards. Type of stroke was recorded according to criteria of world health organization. RESULTS: Analysis of collected data was performed by STATA-11 software and performing X2-test and Ttest showed a significant association (Odds ratio, 1.29 (1.64- 1.02); P value=0.033), between stroke and positive family history. Stroke occurs in patients older than 55 years more than 3 times compared to patients less than 55 years. Also, in patients those have positive family history of stroke, it occurs more than 29% of patients compared with who have not family history of stroke. The most effect of family history was showed at first on sibling and then in mother, children and also father. For others risk factors such as hypertension and diabetes associated with stroke in patients, there was no significant association (Odds ratio, 0.96 (1.10- 0.85); P value=0.92). 84 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 168 Prognostic value of early CT- Scan findings in middle cerebral artery infarction Iranmanesh F, Gadari F, Esmeli F Neurology Research Center, Kerman Medical University, Kerman, Iran BACKGROUND: Some patients with massive ischemic infarction are at risk for massive brain edema and death. Recent studies show that, early CT-Scan findings may have prognostic value for detection of malignant course. In this study, we evaluated prognostic value of early CT scan findings in middle cerebral artery infarction. METHODS: In this cross-sectional study, frequencies of early CT- Scan findings within 6 h after stroke onset in 150 patients suffering middle cerebral artery infarction were collected. The diagnosis of middle cerebral artery infarction was confirmed by brain MRI. The patients fallowed for one month. The data were analyzed with software SPSS16. RESULTS: Twenty three (15.3%) patients had early CT-Scan findings. In patients who were died, 13 had early CT scan finding and 9 patients were without any changes. This difference was statistically significant (P≤0.05). CONCLUSION: The present study showed that early CT scan findings have predictive value in patients with ischemic stroke. 85 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 169 Association between ankle-brachial index and cerebral vessels stenosis in acute ischemic stroke patients Hosseinali Ebrahimi, Farad Iranmanesh Neurology Research Center, Kerman, Iran BACKGROUND: Previous studies show that ankle-brachial index (ABI) significantly correlated with mortality and functional outcome in patients with ischemic stroke. Some studies point to association between specific vessels involvement and ABI. The aim of this study was to investigate, association between ABI with intra and extra cerebral vessels stenosis in acute ischemic stroke patients. METHODS: In this cross-sectional study, 284 patients with acute non-embolic ischemic stroke were evaluated. The diagnosis was confirmed by physical examination, embolic evaluation and neuroimaging. ABI measured within 24 hours after stroke. Doppler ultrasound was done in the first 5 days of stroke onset. To analyze the data, t-test were used. RESULTS: In this study 52.4% was male. Abnormal ABI was found in 20.4%. Patients with abnormal ABI were more likely to have intracranial arteries stenosis. Multiple logistic regression analysis showed that hyperlipidemia was independent factors associated with abnormal ABI. CONCLUSION: Our data showed that the prevalence of abnormal ABI in patients with large vessels atherosclerotic infarction is high. Abnormal ABI is associated with intracranial artery stenosis. 86 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 170 Comparison of stroke risk factors in first-ever ischemic stroke patients and patients with recurrence Shafa MA, Iranmanesh F, Shafa MSH Neuroscience Research Center, Kerman University of Medical Sciences, Iran BACKGROUND: Stroke is the most frequent, as well as the most fatal neurologic disease. Although in almost all societies, ischemic stroke risk factors have been identified in various countries, risk factors for recurrence are different. PURPOSE: The aim of our study was comparison stroke risk factors in first- ever ischemic stroke patients and patients with recurrence. METHODS: This study was a cross-sectional study on 250 patients with ischemic stroke. The diagnosis was confirmed by brain MRI. Patients according to medical history and evaluation by a neurologist and neuroimaging divided in 2 groups. The first group of patients had new stroke and other group of patients had recurrent stroke. RESULTS: Forty three (17.2%) patients had stroke recurrence. Recurrence was more frequent in men. In patients with first- ever ischemic stroke hypertension, diabetes and ischemic heart disease were the more frequent risk factors but in patients with recurrence hypertension, hyperlipidemia and diabetes were frequent. There was significant correlation between recurrence and age, hyperlipidemia and ischemic heart disease. CONCLUSION: Ischemic stroke recurrence in more frequent in men. Patients with old age, hyperlipidemia and ischemic heart disease are more susceptible to stroke recurrence. 87 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 171 Prognostic value of uric acid in patients with ischemic stroke Hamzei Moghaddam A, Iranmanesh F, Hamzei Moghaddam R, Eslami H Neurology Research Center, Kerman University of Medical Sciences, Iran BACKGROUND: Ischemic stroke is one of the most common neurological diseases. Impact of high level of uric acid on ischemic stroke is still controversial. We conducted this study to investigate the correlation between hyperuricemia and stroke recurrence in patients with ischemic infarction. METHODS: This was a cross sectional study on patients with acute ischemic stroke. The diagnosis was confirmed by MRI. Serum level of uric acid in the first 24 hours of admission was measured with photometry method. The patients fallowed for three months in term of recurrence. The data were analyzed with software SPSS16. RESULTS: Hyperuricemia was seen in 24% of patients. Mean serum level of uric acid in patients with recurrence was 6.6±1.3 mg/dl and in patients without recurrence was 5.2±1.5 mg/dl. There was a significant relationship between hyperuricemia and stroke recurrence (P≤0.05). CONCLUSION: Hyperuricemia is risk factor for recurrence in patients with acute ischemic stroke. 88 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 172 Relation of personal stress and tension with cerebrovascular accidents Kavian Ghandehari, Mohammad Reza Davari, Mohammad Reza Sobhani, Mohammad Mousavi Mirzaei, Elnaz Kiadarbansari, Sara Asaadi, Mehdi Amjadi Neurocognitive Research Center, Mashhad University of Medical Sciences, Mashhad, Iran BACKGROUND: Stress is among novel risk factors of stroke. Researches about influence of stress in epidemiology and pathophysiology of stroke are scare. METHODS: Consecutive stroke patients admitted in Ghaem hospital, Mashhad, Iran during September to December 2014 were assessed by a standard stress questionnaire scale and compared with age and gender matched controls. A modified version of Holmes and Rahe stress scale served for assessment of stress. Case and control groups were categorized as high and low stress people as more than or less than 75 score respectively. Etiology of ischemic stroke was determined based on Asian Stroke Criteria by a stroke neurologist with a standard battery of diagnostic investigations. RESULTS: 361 stroke patients (191 Females, 170 Males) and 190 controls (100 Females, 90 Male) were evaluated. Stroke patients included 305 brain infarction and 56 intracerebral hemorrhage (ICH). High stress score was significantly more frequent in whole of 361 stroke patients and ICH group compared to controls; p=0.010, OR=1.817 and p=0.000, OR=5.333, respectively. Distribution of high stress score was not significantly different in patients with brain infarction compared to controls; p=0.178, OR=1.388. Distribution of high stress score was not significantly different in uncertain, cardioembolic and mixed etiologic subtypes of brain infarction compared to controls; p=0.375, p=0.207 and p=0.688, respectively. While, high stress score was significantly more frequent in atherothrombotic subtype of brain infarction than controls, p=0.037. Influence of gender on distribution of high stress score within our 361 stroke patients was not significant (p=0.281). High stress score was significantly more frequent in ICH than patients with brain infarction (p<0.0001). CONCLUSION: Stress is an important risk factor of ICH and atherothrombotic brain infarction. 89 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 173 Stroke Prevention in Very Old Patients: What is the Strategy of Choice? Hossein Pakdaman1, Ehsan Sharifipour2 1-Department of Neurology, Shahid Beheshti University of Medical Sciences, Tehran, Iran 2- Neuroscience Research Center (NSRC), Tabriz University of Medical Sciences, Tabriz, Iran Oldest old patients (≥80 years) make up a third of ischemic stroke (IS) patients and they have higher morbidity and mortality rate among these patients. They are not only at higher risk of experiencing stroke, but also have multiple comorbidities that make treatment for secondary stroke prevention challenging. Very few clinical trials specifically related to secondary stroke prevention treatment efficacy have focused on these patients. Therefore, evidence-based recommendations for treatment specific to this population are not available. Some of the special considerations for stroke prevention treatments in older patients include careful titration of blood-pressure-lowering drugs to avoid hypotension, the risk of haemorrhagic stroke with HMG-CoA reductase inhibitors (statins) and weighing the risk of recurrent ischaemia versus bleeding in patients taking antiplatelet or anticoagulant therapy. The risk of periprocedural complications appears to be high with both carotid angioplasty and stenting and carotid endarterectomy in older patients with carotid stenosis. Other common issues in older patients include adverse drug events, recognizing the risk of dementia, depression and osteoporosis and deciding when to discontinue secondary stroke prevention. In this review, we provide the practitioner with the evidence related to specific approaches to secondary stroke prevention in older patients, and identify the knowledge gaps that currently limit our ability to appropriately treat this vulnerable population. 90 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 174 Evaluation of Cardiac Sources of Emboli by Transesophageal Echocardiography in the Ischemic Stroke Patients in Shiraz Sadegh Izadi1, Mohammad Amin Toodeji2, Abdolhamid Shariat1, Mohamad Hosin Nikoo3 1-Clinical Neurology Research Center, Neuroscience Research Center, Medical School, Shiraz University of Medical Sciences, Shiraz, Iran 2-Student Research Committee, Shiraz University of Medical Sciences, Shiraz Iran 3-Department of Cardiology, Medical School, Shiraz University of Medical Sciences, Shiraz, Iran BACKGROUND: Embolus is one of the causes of ischemic stroke that can be due to cardiac sources such as valvular heart diseases and atrial fibrillation and atheroma of the aorta. Transesophageal echocardiography (TEE) is superior for identifying potential cardiac source of emboli. Due to insufficient data about TEE findings in ischemic stroke in Iran, the present study was done to evaluate cardiac source of emboli by TEE. The main aim of this study was to describe the cardiogenic sources of emboli by TEE in the ischemic stroke patients. METHODS: This is a hospital-based cross-sectional study conducted during a 13-month period from January 2012 to February 2013in Shiraz Nemazee teaching hospital. Patients that referred to this center and were admitted with stroke diagnosis were included but hemorrhagic stroke cases were excluded. 229 patients with ischemic stroke diagnosis were included and underwent TEE. RESULTS: Causes of cardiac emboli were detected in 65 cases (40.7%) and categorized to high-risk (29.7%) and potential risk (11%). High risk cardiac sources including atrial fibrillation (8.7%), mitral valve disease (MS or MI) 11 cases (4.75%), aortic valve disease (AS or AI) 8 (3.5%), prosthetic valve 3 (1.35%), dilated cardiomyopathy 45 (19.65%) and congestive heart failure with ejection fraction <30% in 8 cases (3.5%). Potential cardiac sources of emboli comprising 7 cases (3.05%) septal aneurysm, 4 (1.75%) left ventricular hypokinesia, 13 (5.7%) mitral annular calcification and 9 cases (3.95%) complex atheroma in the ascending aorta or proximal arch. CONCLUSION: Our study showed that high risk cardiac source of emboli can be detected by TEE in a considerable percentage of ischemic stroke patients. The most common high risk cardiac sources were dilated cardiomyopathy and valvular heart diseases. 91 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 175 Comparing cerebral venous sinus thrombosis in the Ramadan and non Ramadan months in Shiraz between 2003-2013 Sadegh Izadi Clinical Neurology Research Center, Shiraz University of Medical Sciences, Shiraz, Iran BACKGROUND: Cerebral venous sinus thrombosis (CSVT) was described in 1825 for the first time. It was seen in all ages. The true prevalence rate is not clear. It was suggested that the prevalence rate increase during fasting and in the month of Ramadan. Methods: In a cross sectional retrospective study the data of all the patients with diagnosis of CSVT that were admitted in the shiraz Namazi hospital in the Ramadan and non Ramadan months since 2003-2013 gathered from their charts. The selected data including age, sex, oral contraceptive pill consumption, pregnancy, complication of CSVT and MRI findings obtained and statistical analysis was recorded. RESULTS: Among 49 patients 27 patients (55%) in the Ramadan and 22 (45%) in the non Ramadan months were diagnosed as CSVT. 85.7% of them were female and the mean age was 37±13.9 years. The most frequent risk factor was OCP consumption. Total mortality rate was 8.2%. CONCLUSION: Although the frequency and complications of CSVT was more common in the Ramadan months but it was not statistically significant. 92 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 176 Oral contraceptive-related cerebral venous thrombosis as an initial manifestation of antiphospholipid syndrome in the absence of systemic lupus erythematosus Payam Saadat1, Reza Mohseni Ahangar2 1-Department of Neurology, Babol University of Medical Science, Babol, Iran 2- Department of Internal Medicine, Babol University of Medical Science, Babol, Iran Cerebral venous sinus thrombosis is a rare and potentially life-threatening neurologic manifestation of antiphospholipid syndrome. Oral contraceptive pills may increase the risk of vascular events, even in people without family history of venous thrombosis. A 31-year-old woman presented with four weeks of constant headache. She had a history of taking OCP for one year. The results of brain magnetic resonance imaging and venography confirmed a diagnosis of cerebral venous sinus thrombosis. The serum anticardiolipin and antiphospholipid antibodies were elevated and a definitive diagnosis of antiphospholipid syndrome was made. The present report demonstrates the importance of screening for antiphospholipid antibodies in patients presenting with cerebral venous sinus thrombosis, despite history of taking OCP. 93 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 177 Evaluation of effect of Intravenous Magnesium Sulfate in Clinical Improvement of Patients with Acute Stroke in MCA Territory in Alavi Hospital Fattahzadeh A. Ghasem, Atalu Abolfazl, Ghasemi M, Tarassoli N Ardabil University of Medical Science, Ardabil, Iran BACKGROUND: This study evaluated the effect of intravenous magnesium sulfate in clinical improvement of the patients with acute stroke. In various studies, there is a lot of information about the use of magnesium sulfate in different conditions of brain ischemia. While neuroprotective effects of magnesium sulphate as a neuroprotective agent has been demonstrated in focal and global brain ischemia in animal models. However, the effect of this agent is still unclear. METHODS: Eighty patients (47 percent of patients were female and 53 percent were male) with acute ischemic stroke signs and symptoms, lasting less than 12 hours of ischemia, were included in the study. Patients were divided into two groups; 40 patients received 4 g of MgSO4 over 15 minutes and then 16 g over the next 24 hours, and the other 40 patients received placebo. RESULTS: The results showed that magnesium sulphate administrated group had better clinical improvement rate than control group. The number of patients with Grade III decreased in magnesium received group and patients with Grade II, I increased. After 2 weeks, patients with Grade III decreased to 12.5% and the patients with Grade II and I increased to 50% and 37.5%, respectively (based on NIHSS score). CONCLUSION: According to this study, magnesium sulfate can be used as a neuroprotective agent in patients with acute ischemic stroke. 94 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 178 Efficacy of Citalopram on Ischemic Stroke Functional Outcome: A Randomized Clinical Trial Daryoush Savadi Oskouie1, Ehsan Sharifipour1, Masoud Nikanfar1, Mazyar Hashemilar1, Homayoun Sadeghi Bazargani2, Samad EJ Golzari3, Saeed Ghazanfari Amlashi1, Zahra Abbaszade4, Elyar Sadeghihokmabadi1, Reza Rikhtegar1 1-Department of Neurology, Neuroscience Research Center (NSRC), Tabriz University of Medical Sciences, Razi Hospital, Tabriz, Iran 2-Department of Statistic and Epidemiology, Road Traffic Injury Research Center (RTIRC), Department of Statistic and Epidemiology, Tabriz University of Medical Sciences, Tabriz, Iran 3-Department of Anesthesiology, Department of Anesthesiology and Intensive Care, Tabriz University of Medical Sciences, Tabriz, Iran 4-Department of Psychiatry, Tabriz University of Medical Sciences, Razi Hospital, Tabriz, Iran BACKGROUND: Stroke is one of the main causes of death and disability in the adult population and recovery from it is considered by many researchers. PURPOSE: The aim of the present study was to evaluate the efficacy of citalopram on 3-mounth functional outcome of non-depressed acute ischemic stroke (AIS) patients. METHODS: In a randomized, placebo controlled clinical trial, 144 patients with AIS were studied for 3 months. In one group, the patients received oral citalopram 20 mg (once daily) and in the other group, they received placebo. All patients received standard care including physiotherapy. Patients with depression were excluded from the study. Primary outcome was set to a 50% reduction in the 3-month National Institutes of Health stroke scale (NIHSS) compared to the baseline scores. RESULTS: Of 144 eligible patients, 123 with mean age of 66.39 (62 in citalopram group and 61 in placebo group) were considered for the final analysis. The primary outcome of the study was obtained in 61 patients (98.3%) of citalopram group and 34 patients (68%) of placebo group (p<0.000) with the risk ratio and number needed to treat of 10.6 (CI: 1.6-71.8) and 1.8 (CI: 1.4-2.4), respectively. No major adverse events were found in either group. CONCLUSION: Citalopram is a safe and tolerable medication in patients with AIS and could improve functional outcome in these patients. 95 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 179 Relation of Stroke Risk Factors with Specific Stroke Subtypes and Territories Farhad Assarzadegan, Hanif Tabesh, Arya Shoghli, Mahmood Ghafoori Yazdi, Hadi Tabesh, Parnaz Daneshpajooh, Mehdi Yaseri School of Medicine, Shahid Beheshti University of Medical Sciences (SBMU), Tehran, Iran BACKGROUND: Although the risk factors of ischemic strokes are well defined, there is slight information about their relations with the etiologies of ischemic strokes. This study investigates the distribution of ischemic stroke risk factors and their connections to diverse etiologies of cerebrovascular attack (CVA) and specific ischemic regions of brain. METHODS: In this cross sectional study, we analyzed the data of patients with definite diagnosis of CVA, excluding hemorrhagic strokes, registered in Imam Hossein Medical Center in Tehran, Iran. The data were collected from entire archived medical records from March 2010 till September 2012, retrospectively. RESULTS: Out of 1696 cases a total of 1011 subjects, 487 (48.2%) males and 524 (51.8%) females with mean age of 68.91±13.54 were included in the study. Patients suffering from atrial fibrillation (AF), valvular heart disease (VHD), and dilated cardiomyopathy were more prone to develop cardioembolic stroke (OR (95%CI): 19.33(11.98-31.17) 31.91(21.69-41.96), 22.73(6.73-76.75) respectively). Those with diabetes mellitus (DM), carotid artery stenosis and dyslipidemia (DLP) had a higher prevalence of macroangiopathic stroke (ORs (95%CIs): 1.83(1.37-2.43), 5.75(3.89-8.48), 1.35 (1.02-1.79) respectively). Ischemic heart disease (IHD), AF, and VHD were associated with stroke in the brain territory supplied by middle cerebral artery (MCA) (ORs (95%CIs): 1.39(1.08-1.79), 1.96(1.33-2.89), 1.38(1.03-1.85) respectively) while DM and carotid artery stenosis were correspondent with posterior cerebral artery (PCA) stroke (ORs (95%CIs): 1.46(1.06-2.01), 1.47(1.04-2.08) respectively). Peripheral artery disease (PAD) and smoking were related with watershed stroke (ORs (95%CIs): 13.27(1.30-134.61), 4.13(1.4511.73) respectively). Furthermore, we observed that opium addiction was associated with stroke resulted from carotid arteries stenosis (OR (95%CI): 4.15(1.75-9.83). CONCLUSION: The diagnosis of the weight of each risk factor of ischemic strokes on different etiologies and territories of ischemia can assist care providers for a more efficient prevention of strokes. The results of this study can also be a basis for further investigations to corroborate the pathophysiology of such relations. 96 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 NEUROLOGY & GENERAL MEDICINE 97 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 180 A Case Report of Neuroleptic Malignant Syndrome Following Carbamazepine Withdrawal Reza Boostani, Ali Ghabeli Juibary Student Research Committee, Faculty of Medicine, Mashhad University of Medical Sciences, Mashhad, Iran CASE PRESENTATION: A 34-year-old male with a history of bipolar mood disorder and seizures was admitted to the hospital with changes in mental status, ataxia, nausea, development of tremors, and a temperature of 39 °C. Initial differential diagnoses included seizure, aspiration, stroke, and infection. Once these were excluded, NMS was considered. The patient exhibited other characteristics of NMS during hospitalization, including lead pipe rigidity, tachycardia, and high CPK level (up to 2392 IU/L). Drug therapy on presentation included olanzapine 5 mg 1 times per day, bromocriptine BD, amantadine 100 mg BD. Carbamazepine 100 mg every 12 hours added to treatment 9 days after admission. He reportedly had discontinued carbamazepine a month before admission. The patient received traditional treatment for NMS, which included bromocriptine, intravenous fluids, and supportive care. The NMS resolved in 3 days after initiation of carbamazepine. CONCLUSION: Clinicians should be aware that NMS with EPS can occur with carbamazepine withdrawal. 98 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 181 -2518 A/G polymorphism of the Monocyte chemoattractant protein-1 (MCP-1) gene in Tunisian Alzheimer patients in relation to β-amyloid (1-42) Limem Khalifa, Hafsa Jawhar, Charfeddine Bassem, Dridi Hedi, Smach Mohamed Ali Faculty of Medicine of Sousse, Sousse, Tunisia BACKGROUND: Inflammation of the central nervous system (neuroinflammation) is now recognized to be a feature of all neurological disorders. It is characterized by the production of various molecules that initiate the recruitment of immune cells to the lesion sites, including in the brain. Monocyte chemoattractant proteins (MCPs) might play an important role in Alzheimer's disease (AD) pathology through participating to the maturation of senile plaques or APP endocytosis. METHODS: In this study, we evaluated whether the MCP-1 (2518) polymorphism might be responsible for susceptibility to AD, utilizing a clinically well-defined group of 173 sporadic AD patients and 150 control subjects. RESULTS: The distribution of genotype and allele frequencies of the MCP-1 (-2518G/A) polymorphism did not differ significantly between AD and control groups (p>0.05). Stratifying by ApoE genotype, gender or age at onset, no differences in both allele frequencies were observed. CONCLUSION: Our results suggest that the A-2518G polymorphism in MCP-1 gene may not play a major role in the development of AD in the Tunisian population, but its presence correlates with lower levels of CSF Aβ42, which can contribute to increase the inflammatory process occurring in AD. 99 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 182 Neurological involvement in Degos syndrome: A comprehensive review of literature Samaneh Yousefi1, Afshin Borhani Haghighi2,3, Anahid Safari4, Aixa Garcia-Toledo5, Lee Shapiro6 1-Student Research committee, Fasa University of Medical Sciences, Fasa, Iran 2-Clinical Neurology Research Center, Shiraz University of Medical Sciences, Shiraz, Iran 3-Deparment of Neurology, Shiraz University of Medical Sciences, Shiraz, Iran 4-Deparment of Pharmacology, Kazeroon Azad University, Kazeroon, Iran 5-Steffens Scleroderma Center, Albany, New York, USA, Albany Medical College, Albany, New York, USA 6-The Center for Rheumatology, Albany, New York, USA BACKGROUND: Malignant atrophic papulosis (Degos disease) is an obliterative vasculopathy of unknown origin, characterized by erythematous papular skin lesions but the central nervous system (Neuro-Degos syndrome) and gastrointestinal tract can also be involved in its progressive course. Review Summary: The frequency of neurologic manifestations is about 20%. The main pathological feature of neurologic involvement is vascular occlusion resulting in ischemic changes. Central nervous system presentations include 1) the parenchymal form presenting with brain, spinal cord manifestations and meningo-encephalitis and meningo-myelitis and 2) the neuro-vascular form presenting with large cerebral infarcts, intracranial hemorrhage, subarachnoid hemorrhage, subdural hematoma and venous sinus thrombosis. Predilection to subdural hematoma or hygroma is characteristic for Neuro-Degos syndrome in comparison to other vasculopathy and vasculitis. The peripheral nervous system manifestations are less common and include polyradiculopathy neuropathy, and myopathy. CSF analysis usually shows mild to moderate pleocytosis, increased protein content, and normal glucose. Brain MRI may reveal cortical, subcortical and deep white matter ischemic lesions with possible nodular, leptomeningeal, dural, or ependymal enhancement. Spinal cord MRI may reveal patchy lesions from the periphery to the center or cord atrophy in progressive course. Neuro-degos has a grave prognosis, the interval from onset of papulosis to death averages two years in patients with neurological involvement. There is no confirmed treatment for malignant atrophic papulosis but there are promising reports with Eculizumab and Treprostinil. CONCLUSION: Neuro-Degos syndrome must be considered in the differential diagnosis of any disease with atrophic skin lesions and neurologic manifestations. 100 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 183 The assessment of asymmetry in prefrontal regions in individuals with aggression Parichehr Ahmadi, Vida Mamagani 1-Department of Medical Sciences, Islamic Azad University, Tabriz branch, Tabriz, Iran 2-General Office of Legal Medicine, Tabriz, Iran BACKGROUND: Several studies have been conducted to determine the criteria for diagnosis and evaluation of aggression. Despite it still has a way to get through it, based on the evaluation of brain function, aggressive behavior is not specified. PURPOSE: The aim of this study was to determine the degree of asymmetry in prefrontal regions of the brain in individuals with aggression. METHODS: The sample consists of 30 individuals that go to the clinic for the first time to treat the aggression and a total of 30 healthy and normal control subjects matched for age and sex with aggression patients. For diagnosis of patients, Psychiatric Diagnosis and Aggression Questionnaire of Buss and Perry (1992) was used. Brain activity was measured by quantitative EEG. RESULTS: The participants in both groups were compared using analysis of variance showed that the two groups do not differ in terms of two waves theta and delta. In individuals with aggression, increase in alpha activity in the left, and increase in beta activity in right lobe was observed. CONCLUSION: The results showed the importance of the prefrontal cortex in the study, assessment, diagnosis and treatment of aggressive patients. 101 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 184 Medical, non-vestibular causes of dizziness or vertigo Shahir Mazaheri Neurology Department, Farshchian Hospital, Hamadan, Iran Dizziness and vertigo have a broad differential diagnosis. Thus, atypical signs and symptoms for an underlying vestibular disorder combined with abnormal neurotological examination mandate a more extensive evaluation. Approximately 50% of patients presenting with dizziness or vertigo to the emergency department have an underlying non-vestibular medical disorder, whereas only about 33% are diagnosed with a neurotological (vestibular) disease. The percentage of dangerous disorders in dizzy patients presenting to the emergency room increases with age (from <10% at age ≤25 to >25% at age ≥ 75 years). Frequent non-vestibular causes include vasovagal syncope and dangerous conditions such as cardiac arrhythmia, electrolyte or fluid disturbances, cardiovascular disorders, anemia secondary to gastrointestinal bleeding, and hypoglycaemia. Categories provided by most studies segregating the underlying cause of dizziness or vertigo in patients presenting to the ED were oto-vestibular (13–34%), other neurological disorders (5–11%), cardiovascular disorders including cardiac arrhythmia (4–21%), psychiatric diagnoses (2-14%) and non-cardiovascular general medical diagnoses (8–28%). The five most frequent non-vestibular causes according to Newman-Toker and colleagues (2008) were vasovagal syncope (6.6%), electrolyte and fluid disorders (5.6%), cardiac arrhythmia (3.2%), anemia (1.6%), and hypoglycaemia (1.4%). Whereas some of these disorders are recurrent and benign, others are potentially life threatening if not recognized rapidly. Whereas (pre)syncope in general is considered a benign disorder, the mortality rate in cardiogenic syncope reaches 30% in the first year, underlining the need to better identify non-vestibular causes of dizziness or vertigo and initiate appropriate treatment. Reduction or cessation of drugs inducing the patient’s complaints, administration of electrolyte supplements, and antiarrhythmic treatment (e.g. by medication or by placing a pacemaker/implantable conversion device) may be required—if an underlying cause can be identified at all. Treatment options for vasovagal syncope are usually non-pharmacological and emphasize avoidance of triggers and mechanical or behavioral strategies to decrease underlying orthostasis. Venous pooling can be counteracted by anti-orthostatic maneuvers such as squatting or standing with the legs crossed. 102 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 185 Approach to a Patient with Narcolepsy Shahir Mazaheri, Akram Hosseinzadeh Neurology Department, Farshchian Hospital, Hamadan, Iran Narcolepsy is one of the most common hypersomnias of the central nervous system origin. Its primary symptom is that of excessive daytime sleepiness (EDS). It is estimated to occur in 0.002–0.18% of the general population. The US prevalence is estimated as between 0.03% and 0.07%, with the condition estimated to occur in 1 in 2000 of Americans. The male-to-female prevalence is equal. The symptoms usually appear in the teens and 20s but in many cases there is a 10-year period between onset and diagnosis. Approximately 50% of adults with the disorder retrospectively report symptoms beginning in their teenage years. The clinical tetrad of narcolepsy corresponding to the criteria of the International Classification of Sleep Disorders includes EDS, cataplexy (70%), hypnogogic hallucinations (30%), and sleep paralysis (25%) and only 10–15% of patients experience the full tetrad. Excessive sleepiness is often the first reported symptom, followed by cataplexy. EDS alone or in combination with hypnogogic hallucinations and/or sleep paralysis is the presenting symptom in approximately 90% of patients. The pathophysiology is unclear. There is some evidence that genetic predisposition, abnormal neurotransmitter functioning, and abnormal immunemodulation may all play a role in the development of narcolepsy. History is important in evaluating other possible causes of EDS. Diagnostic testing with a polysomnogram and next-day Multiple Sleep Latency Test helps to eliminate other causes of EDS such as sleep apnea, periodic limb movements of sleep, and idiopathic hypersomnia. Narcolepsy can be differentiated from idiopathic hypersomnia by many key features Effective pharmacotherapy can require multiple medications. Stimulant medications are used to treat excessive sleepiness and REM-suppressant medications are used to treat cataplexy. Sodium oxybatecan treat both EDS and cataplexy. Modafinil and armodafinil are chosen as first-line stimulant medications due to their limited side-effect profile. Commonly used older stimulant medications include methylphenidate and dextroamphetamine. Newer REM-suppressant medications that are effective in cataplexy include the antidepressant venlafaxine. 103 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 186 Electrophysiological findings landmarks in patients with auditory neuropathy Mehrnaz Hosseini Department of Audiology, Iran University of Medical Sciences, Tehran, Iran BACKGROUND: Auditory neuropathy spectrum disorder, and the subtype auditory neuropathy (AN), usually characterized by normal outer hair cell function but disordered neural conduction in the auditory pathway, which is considered to be a functional disorder rather than an anatomical abnormality. PURPOSE: The aim of this study is to describe the electrophysiological tests results characteristics of patients with AN. METHODS: Related studies were searched using the words of "auditory neuropathy" and other related keywords, in the databases of PubMed, Scopus, Proquest, and Google scholar. Just most related articles were selected to write this review article. RESULTS And CONCLUSION: Abnormal responses in auditory brainstem response and stapedial reflex (including absence of response, elevated threshold, or perturbed waveform), large cochlear microphonic in electrocochleography, and presence of otoacoustic emissions, are the most recognizable findings in electophysiologic tests. Variations in the results of electrophysiologic tests can be attributed to the various site of lesions related to different pathologies triggered AN. It seems that appearance of electrical auditory brainstem response after cochlear implantation, as a management for patients with AN, can be considered as a good prognosis to improve speech perception after surgery in these patients. 104 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 187 Supratentorial cortical ependymoma: An unusual presentation of a rare tumor case report Chitsaz A, Mohaghegh M Department of Neurology, Isfahan University of Medical Sciences, Isfahan, Iran Ependymomas are glial tumors derived from ependymal cells lining the ventricles and the central canal of the spinal cord. Two-thirds of ependymomas arise in the infratentorial or intraventricular, whereas onethird are located in supratentorial space but supratentorial cortical ependymomas are very rate. We report a case of a cortical ependymoma in 17-year-old boy. The patient presented with transient recurrent right weakness and diplopia. This tumor was located in the left parieto-occipital region and he had gross total excision, microscopy and immunohistochemistry showed grade III differentiation ependymoma. 105 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 188 Psychological symptoms in patients with chronic dizziness Ahmad Chitsaz, Fariborz Khorvash Department of Neurology, Isfahan University of Medical Sciences, Isfahan, Iran BACKGROUND: Dizziness is one of the most commonly occurring chief complaints in neurology. PURPOSE: The aim of this study was to differentiate patients with dizziness according to originate and some to form vertigo and evaluate the relationship of dizziness/vertigo symptoms with psychological symptoms in patients with chronic vertigo and dizziness. METHODS: This multicenter, cross-sectional study was conducted on 18- to 65 year-old patients referred into two neurology outpatient clinics in the city of Isfahan, Iran, during 2012-2013. Patients completed the symptom check list (SCL-90-R) and vertigo symptom scale-short form (VSS-SF). RESULTS: During the study period, 179 patients (mean age 30.9±0.1 years, 81.7 women) were included in 74.3% of the patients (n=133) dizziness was organic and in 25.7% (n=46) of nonorganic origin, compared with the organic group. The patients with nonorganic dizziness had much more scores on SCL90-R. CONCLUSION: The results indicate that psychological symptoms are associated with dizziness symptoms in patients with psychiatric disorders and it should be included in the differential diagnosis in patients with chronic dizziness. Hence, in cases of dizziness disorders, early interdisciplinary cooperation is both helpful and essential during diagnosis work up to include signs of somatic and psychosomatic origin and prevent chronification and reduce the severe handicap and high medical costs. 106 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 189 Metronidazole-induced toxicity in a patient with liver abscess Masoume Nazeri1, Amin Abollhasani Foroughi2, Hora Heidari1 1-Department of Neurology, Shiraz University of Medical Sciences, Shiraz, Iran 2-Department of Radiology, Shiraz University of Medical Sciences, Shiraz, Iran BACKGROUND: Metronidazole-induced CNS toxicity causes some neurologic symptoms including ataxia, encephalopathy and peripheral neuropathy. It is associated with characteristic MRI change in the dentate nuclei. CASE PRESENTATION: A 31-year-old female known case of ALL was admitted in our hospital due to abdominal pain. After completion of work ups liver abscess was diagnosed. Starting metronidazole therapy, the patient developed diplopia and vertigo. MRI brain showed T2-weighted hyperintensities within dentate nucleus of cerebellum. Our patient's clinical presentation and MRI findings were most consistent with metronidazole toxicity, so we discontinued metronidazole and cerebellar symptoms were resolved. CONCLUSION: Metronidazole-induced neurologic toxicity is a rare complication. MR imaging is helpful in clinically suspected patients. Discontinuation of drug results in resolution of symptoms. 107 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 190 Is Obesity Correlated with Cognitive Impairment? Farzad Ashrafi1, Behdad Behnam1, Mehran Arab Ahmadi1, Hossein Pakdaman2, Afsaneh Zarghi1, Lida Shashaani3, HamidReza Rokhsatyazdi4, Hossein Delavar Kasmaei4 1-Functional Neurosurgery Research Center, Shohada Tajrish Hospital, Shahid Beheshti University of Medical Sciences, Tehran, Iran 2-Department of Neurology, Loghman-Hakim Hospital, Shahid Beheshti University of Medical Sciences, Tehran, Iran 3-Department of Internal Medicine, Shohada Tajrish Hospital, Shahid Beheshti University of Medical Sciences, Tehran, Iran 4-Department of Neurology, Shohada Tajrish Hospital, Shahid Beheshti University of Medical Sciences, Tehran, Iran BACKGROUND: Because of well-established role of obesity in brain lesions, progressing cognitive deficits in obese patients has been recently suggested. In current study and for the first time, we aimed to assess cognition status in Iranian obese people and to compare it with non-obese individuals. METHODS: One hundred and eighteen consecutive patients with the different cardiovascular and metabolic primary complaints were assigned to obese group and non-obese group. Cognitive status was assessed at initial visiting using the Montreal Cognitive Assessment (MOCA) questionnaire. RESULTS: Mean total cognitive score in obese patients was lower than non-obese ones. In total, 25% of obese patients and 60% of non-obese patients had normal cognitive function. No significant difference was also found in different sub domains of cognitive ability between obese and non-obese groups. None of the cognitive domains had significant association with BMI as the considered indicator for defining obesity. Based on multivariate linear regression modeling, obesity could not predict cognitive deficit. CONCLUSION: Our survey could not demonstrate an association between obesity and cognitive impairment in a sample of Iranian patients. 108 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 DEMENTIA 109 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 191 Serum level of Copper, Zinc and Magnesium in Alzheimer's disease Seyed Ali Masoud Kashan University of Medical Sciences, Kashan, Iran BACKGROUND: Alzheimer's disease (AD) is a progressive neurodegenerative disorder of unknown etiology characterized by irreversible cognitive and physical deterioration. That result in lack of independent function in patients. According to varies studies and their contradictory results on effects of trace elements like copper, zinc and magnesium on AD, this study was done. METHODS: This cross-sectional study was done on 50 patients with AD who referred to Kashan neurology clinic and didn't consume any Cu, Zn and Mg supplements. They didn't have any disease having significant effects on these elements. Five cc of vein blood was obtained and serum levels of these elements were checked with spectrometry. RESULTS: Among 50 patients, 30 persons (60%) were male and 20 persons (40%) were female. serum Cu level of all patients was within normal range, Serum Zn level in the 3 patients (6%) was under normal range. Forty four patients (88%) were within normal range and 3 patients (6%) were upper normal range. Serum Mg level in 6 patients (12%) was under normal range, 40 patients (80%) was within normal range and 4 patients (8%) was upper normal rang. There wasn’t any relation between serum Cu level and age and gender (p=0.302 & p=0.432, respectively). There wasn’t any relation between serum Zn level and age and gender (P=0.416 & P=0.678, respectively). There wasn’t any relation between serum Mg level and age and gender (P=0.141 & p=0.153, respectively). CONCLUSION: Regarding to these results, trace elements had no significant changes in patients with AD, and that may related to effects of diet behaviors, weather, geographic region and genetic factors on incidence and prophylaxis of AD. 110 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 192 Arthrophytum Scoparium Pomel Extract acetylcholinesterase activity in mice brain improves cognitive performance and affects Med Ali Smach, Jawhar Hafsa, Bassem Charfeddine, Hedi Dridi, Khalifa Limem Department of Biochemistry, Faculty of Medicine Sousse, Sousse, Tunisia BACKGROUND: Arthrophytum scoparium Pomel has been widely used in traditional Tunisian medicine to treat eye and enhance memory. PURPOSE: This study investigates the neuroprotective effect of Arthrophytum scoparium aqueous extract (ASAE) in mice through behavioral and biochemical parameters. METHODS: In this latter investigation, mice injected intraperitoneally with 250 µL of saline (control group), galactose (10%), or aqueous A. Scoparium extract (300mg/kg body weight) for a period of 7 days. Cognitive function was assessed by Y-maze active test after a double training and an initial acquisition trial. RESULTS: The ASAE had high total phenolic contents (32 mg gallic acid equivalents/g dried extract) and flavonoids (1.81 mg catechin equivalents/g dried extract). It exhibited a significantly (p<0.05) hydroxyl radical-scavenging activity (IC50 = 13.9 μg/ml). IC50 value of AChE inhibition of extract was 2.913 mg/ml. The LD50 value was greater than 3000 mg/kg for the aqueous extract of A. scoparium. The mice treated with 300 mg/kg exhibited a significant decrease in avoidance and discrimination errors during a retention trial compared to control group (p<0.05). AChE activity significantly decreased in treated mice. CONCLUSION: The ASAE potentiated memory retention in adult male mice and confirming their use in traditional medicine. 111 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 193 The role of astrocytes in Alzheimer’s disease Athena Sharifi Razavi Department of Neurology, Mazandaran University of Medical Science, Sari, Iran Alzheimer's disease (AD) is a neurodegenerative disease characterized by the aggregation of amyloid βpeptide (Aβ) into β-sheet-rich fibrils. Plaques containing Aβ fibrils have been viewed as the conventional hallmark of AD. However, the actual role of astrocytes in AD remains elusive, as they seem to adopt different functions dependent on disease progression and the extent of accompanying parenchymal inflammation. Increased production of Aβ and altered processing of tau in AD are associated with synaptic dysfunction, neuronal death and cognitive and behavioral deficits. Neuroinflammation is also a prominent feature of AD brain and considerable evidence indicates that inflammatory events play a significant role in modulating the progression of AD. The role of microglia in AD inflammation has long been acknowledged. Substantial evidence now demonstrates that astrocyte-mediated inflammatory responses also influence pathology development, synapse health and neurodegeneration in AD. Astrocytes may contribute to the clearance of Aβ and restrict the spread of inflammation in the brain. Conversely, they may contribute to neurodegeneration in AD by releasing neurotoxins and neglecting crucial metabolic roles. Several anti-inflammatory therapies targeting astrocytes show significant benefit in models of disease, particularly with respect to tau-associated neurodegeneration. However, the effectiveness of these approaches is complex, since modulating inflammatory pathways often has opposing effects on the development of tau and amyloid pathology. An increased understanding of interactions between astrocytes and neurons under different conditions is required for the development of safe and effective astrocyte-based therapies for AD and related neurodegenerative diseases. 112 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 194 The naming disorder in dementia Elham Seihei1, Alireza Mollaei2 1-Musculoskeletal Rehabilitation Research Center, Ahvaz Jundishapur University of Medical Sciences, Ahvaz, Iran 2-Golestan Hospital, Ahvaz Jundishapur University of Medical Sciences, Ahvaz, Iran BACKGROUND: Dementia is a group of symptoms related to memory loss and overall cognitive impairment. Most types of dementias continue to worsen and are usually irreversible. The effects of dementia etiology and severity on the confrontation naming ability of individuals with Alzheimer's, Huntington's, and Parkinson's diseases and multi-infarct dementia are investigated. Naming impairment is a common feature of the language disorder of dementia, yet agreement has not been reached on its mechanisms. PURPOSE: The aim of this review is the naming disorder in dementia. METHODS: Science Direct, Pubmed (2000 through 2015) were searched for English-language studies using a list of keywords. The books about dementia and speech therapy were studied too. RESULTS: Naming dysfunction occurred even in mild dementia, in patients whose overall language function remained normal, and worsened in proportion to the degree both of language deficit and of overall cognitive dysfunction. Perceptual difficulty and word frequency, but not word length, were important determinants of naming performance in demented patients. Although naming impairment is reported as a consequence of dementing illness, confrontation naming is not found to be significantly impaired in mildly involved patients. Further, although moderate Huntington's and Parkinson's patients made more naming errors than normals, only moderate Alzheimer's disease patients are found to be significantly different. CONCLUSION: Regardless of etiology, most misnamings are found to be semantically related or semantically and visually related to the stimulus. Results challenge the theory that misnamings of dementia patients result primarily from misperception. 113 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 195 Studying the Relation of Metapsychoplasticity and behavioral inhibition/activation systems of brain in university students with Emotional/Cognitive Dysfunction Abbas Alimadadi University of Science and Culture, Tehran, Iran BACKGROUND: The term called Plasticity is the specific endowment of nervous system to develop and also to react or adjust to the internal/external environment changes. While, Neuroplasticity refers to changes of neurons or glial cells while the brain develop. Neuroplasticity mechanisms are triggered by various natural/artificial stimuli, which may arise in the internal/external environment and they may differ quantitatively/qualitatively. Plasticity effects can lead to the Positive/Negative development which occurs by learning with regard to the cell changes. Based some study, in longtime frequency of experience emotional problem and cognitive dysfunction has a special plasticity of it down which is negative. Metaplasticity is a level higher than plasticity and also includes the prior synaptic process. The concept of Metapsychoplasticity is consisted of three basic construction sets (Temperament, Attachment style, Defense mechanisms) which of occurs older than the other psychological phenomena such as personality. The formation type of these construction leads to health or pathology in mental or biological and cognitive level. It seems that these structures (Metapsychoplasticity) are probably related to brain functions of behavioral inhibition/activation systems, so lead to cognitive problems. Studying the relation of these factors can be a guide in clinical section especially in the prevention programs. PURPOSE: The aim of this study was investigating the level of Metapsychoplasticity and behavioral inhibition/activation systems of brain in University students with Emotional/Cognitive Dysfunction. METHODS: 287 university students participated in research. High and low 20 percentages were selected based GHQ-28 scale. Also short form Adult Temperament Questionnaire (ATQ), Adult Attachment scale (AA), defense mechanisms questionnaire (ESQ/40) and The Cognitive Failures Questionnaire were used as instrumental research. RESULTS: Data analysis showed that the metapsychplasticty elements and behavioral inhibition/activation systems are significant different between two groups. Students in group with Emotional/Cognitive Dysfunction had insecure attachment, abnormal temperament, immature defense mechanisms and disturbance in behavioral inhibition/activation systems. CONCLUSION: The concept of metapsycholplasticity refers to the basic formation psychological function which has a main role in health and pathology. It seems that person with Emotional/Cognitive Dysfunction is under the influence of these basic factors and also the result of brain inhibition/activation systems functions. These issues may refer to the strong correlation between the metapsychoplasticity and neuroplasticity phenomena. The recent finding would have very important positive effects in therapeutic and preventive plans. 114 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 196 Bosweilia Serrata in preventing dementia in patients with mild cognitive impairment: a randomized clinical trial in Iran Behnaz Sedighi, Kave Shafie, Abbas Pardakhti, Soheila Rezakhani Kerman University of Medical Sciences Kerman, Iran BACKGROUND: Mild cognitive impairment (MCI) is the first stage of dementia. Due to the progression of irreversible dementia, the best time to do any preventative measure is the MCI stage. Currently, no effective treatment has been confirmed at this stage. Bosweilia Serrata, from the earliest times, among of Iranian and Muslims had been used for enhancing memory and learning skills. The present study aimed to investigate the effect of Bosweilia Serrata on the improvement of MCI. METHODS: In a randomized double-blind clinical trial, in Kerman in southeastern Iran 80 patients were enrolled in the intervention group and the placebo group. At baseline, after evaluation by The Montreal Cognitive Assessment (MoCA) test received intervention and follow-up after 3 months and then were evaluated by MoCA test. The t-test to compare groups and mixed model was used. RESULTS: The mean was significantly different between the two groups. The results showed that the memory component had the greatest impact on the average final score (All p-values were ≤0.0001). CONCLUSION: The results showed that the use of Bosweilia Serrata can be effective in preventing dementia in patients with mild cognitive impairment. 115 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 197 Comparison of Post-ischemic Administration of Ginkgo Biloba and Treadmill Running on Ischemia-induced Memory Deficit and Hippocampal Oxidative Stress in Adult Rats Ladan Vaghef, Hassan Bafandeh Gharamaleki Tabriz University, Tabriz, Iran BACKGROUND: General cerebral ischemic leads to neuronal damage and impaired brain function, particularly cognitive functions. The purpose of the present investigation was to compare possible neuroprotective effects of Ginkgo biloba extract and treadmill running exercise on learning and memory in rats were subjected to transient global cerebral ischemia. METHODS: Adult male rats were subjected to transient cerebral ischemia induced by bilateral common carotid occlusion. Then, rats were submitted to treadmill running or were given Ginkgo biloba extract treatment for 2 weeks after cerebral ischemia. Morris water maze (MWM) and shuttle-box test were used to assess effects of treadmill exercise and Ginkgo biloba extract on learning and memory. Then, oxidative stress markers including Superoxide Dismutase, Glutathione Peroxidase, Catalase, and Malondialdehyde were measured in the hippocampus tissue. RESULTS: The results of the shuttle box and MWM tasks showed a decrease in learning and memory in rats subjected to cerebral ischemia. Furthermore, hippocampal oxidative stress was higher in ischemic rats than in controls. The effect of exercise on learning and memory was more pronounced than Ginkgo biloba extract. Indeed, exercised Ischemic rats showed significantly better performances in the both MWM and shuttle box tasks. In ischemic rats treated with Ginkgo, significantly improved performance was seen only in the MWM task. Although these rats displayed better learning and memory in shuttle box task compared to untreated rats, but the differences did not reach statistically significant. Decreased hippocampal oxidative stress was also observed in both exercise - and Ginkgo -treated ischemic rats compared with untreated ischemic rats. CONCLUSION: Taken together, these findings suggest that although both exercise and Ginkgo biloba extract ameliorated cerebral ischemia-induced memory deficit and hippocampal oxidative stress, exercise, however, was more effective than Ginkgo. 116 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 SPINAL CORD DISORDERS 117 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 198 Diagnosis of deformity in neuro-skeletal disorders (Kyphosis & Lordosis) by imagingbased quantitative biomechanical analysis method Mohammadreza Saraei, SeyedEsmaeil Hashemiaghdam, Zohreh Norouzi Tabriz University of Medical Science, Tabriz, Iran BACKGROUND: Imaging-based quantitative biomechanical analysis method (IQBA) is non-invasive, computational and more accurate than existing methods for initial diagnosis of neuro-skeletal disorders. PURPOSE: Diagnosis of abnormality and deformity by using IQBA method in neuro-skeletal disorders of the upper limb including CL, LL and TK. METHODS: This cross-sectional study is done by imaging peripheral areas of the TK, CL, LL and computing those. First, the coordinates of the virtual markers placed on body dysmorphic relative to the vertical axis LLi, MLi, RLi (the vertical axis is aligned and has equal length with 2.5 cm distance of each other, the horizontal axis is tangent to the metatarsus.) measured in both normal and abnormal. Second, the graph of each of them is drew, compared, and quantitative evaluated. At last, the algorithm of detects the type and amount of deformity was presented. RESULTS: The average deviation of normal deformation in cm from the LLi / MLi / RLi in the areas of C, T, L, S, is computed respectively follow as head-on. CL: {(0.1295), (-0.0146), (0.023), (0.027) / (-0.1353), (0.0273), (-0.0150), (-0.0030) / (-0.1231), (0.0277), (-0.0040), (-0.0044)}, TK: {(0.0020), (-0.0404), (0.0205), (0.0241) / (0.0132), (0.0558), (-0.0108), (-0.0098) / (0.0110) (0.0572) (-0.0111), (-0.0121)} and LL: {(0.0821), (0.0221), (0.1589), (0.0406) / (-0.0490), (0.0066), (-0.1382), (0.00004) / (-0.0389), (0.0046), (-0.1375), (0.0169)}. CONCLUSION: According to the results obtained in each of the above anomalies, in the target regions, there are significant differences to the zero line of the vertical axis either increase or decrease that indicates the deformity in those regions. 118 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 199 Diagnostic Approach to Myelopathies Masoud Ghiasian Department of Neurology, Hamadan University of Medical Sciences & Health Services, Hamadan, Iran Myelopathy is a broad term that refers to spinal cord involvement of multiple etiologies. Spinal cord diseases often have devastating consequences, ranging from quadriplegia and paraplegia to severe sensory deficits due to its confinement in a very small area. Many of these diseases are potentially reversible if they are recognized on time, hence the importance of recognizing the significance of magnetic resonance imaging when approaching a multifactorial disease considered as one of the most critical neurological emergencies, where prognosis depends on an early and accurate diagnosis. Traumatic injuries, vascular diseases, infections and inflammatory or autoimmune processes may affect the spinal cord due to its confinement in a very small space. The history, an adequate neurological examination and the study of the cerebrospinal fluid guide the diagnosis of spinal cord injuries. However, imaging is of great importance in order home to determine diagnosis and classify the etiology appropriately. 119 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 200 Stem cell therapy in spinal cord injury: focused on human umbilical cord blood stem cells Ruhollah Hosseini, Gholamreza kaka, Kayvan Yaghoobi, Seyed Homayoon Sadraie, Korosh Mansouri, Alireza Mohammadi Neuroscience Research Center, Baqiyatallah University of Medical Sciences, Isfahan, Iran Spinal cord injury (SCI) is a major cause of disability. Furthermore at present there is no universally accepted treatment. The functional decrease taking after SCI is contributed to both direct mechanical injury and secondary pathophysiological mechanisms that are induced by the initial trauma. There have been many efforts to recover neuronal function from spinal cord injuries, but there are a few confinements in the treatment of spinal cord injuries. The neural stem cell has been noted for its pluripotency to differentiate into various neural cell types. A marked increase in the utilization of umbilical cord blood (UCB) transplantation has been observed in recent years. In this review, we present the recent findings on the therapeutic potential of hUCB as a safe, plausible and powerful cellular source for transplantation in SCI. These multifaceted protective and restorative effects from hUCB grafts may be interdependent and they act in harmony to promote therapeutic benefits for SCI. 120 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 NEUROMETABOLIC 121 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 201 Rett's syndrome, clinical review and genetic update: Report of Five Cases from Northern Iran Mohammadreza Salehi Omran, Ali Ghabeli Juibary Student Research Committee, Faculty of Medicine, Mashhad University of Medical Sciences, Mashhad, Iran & Neurology Department, Ghaem hospital, Mashhad, Iran Rett’s syndrome (RS), a pervasive neurodevelopmental disorder, is being increasingly recognized all over the world, but there is paucity of reports from Iran. Due to its manifestations at any stage of development, it is important to arrive at a correct diagnosis. Five cases are presented, highlighting the need to recognize this relatively uncommon disorder and to differentiate it from various other neurodegenerative disorders. 122 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 202 Rubinstein-Taybi Syndrome (broad thumb-hallux syndrome): A Case Report Mohammadreza Salehi Omran, Hadi Sorkhi, Yaser Asghari Vostakolaee, Ali Ghabeli Juibary Student Research Committee, Faculty of Medicine, Mashhad University of Medical Sciences, Mashhad, Iran & Neurology Department, Ghaem hospital, Mashhad, Iran Rubinstein-Taybi syndrome is a rare genodermatosis with characteristic feature including downward sloping palpebral fissures, broad thumbs and halluces, and mental retardation. Systemic features may involve the cardiac, audiology, ophthalmologic, endocrine, neurologic, and respiratory systems. The syndrome is sporadic in nature and has been linked to microdeletion at 16p13.3 encoding CREB-binding protein gene (CREBBP). We report a 15-year-old girl that was a known case of chronic renal failure with downward slanting palpebral fissures toward the ears, hypertelorism, short stature, beaked nose, micrognathia, strabismus, dental anomalies, large toes, broad thumbs, and mental retardation. 123 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 203 Overview of Charcot-Marie-Tooth type 1A Parisa Aob1, Mohammad Reza Ranjouri2, Mahmoud Shekari Khaniani1,2 1-Medical Genetic Department, Faculty of Medicine, Zanjan University of Medical Sciences, Zanjan, Iran 2-Medical Genetic Department, Faculty of Medicine, Tabriz University of Medical Sciences, Tabriz, Iran Charcot-Marie-Tooth (CMT) is one of the sensory and motor neuropathies with a frequency of 1 in 2500. The syndrome represents a genetically and clinically heterogeneous group of inherited disorders that classified into demyelinating and axonal. This disorder has related to mutations in more than 40 genes affecting glial or neuronal functions. In addition, there are many forms of CMT disease, including CMT1, CMT2, CMT3, CMT4, and CMTX. In addition, the disease is characterized by slowly progressive weakness in the feet and hands, high arches, hammertoes, scoliosis and slow nerve conduction velocity. Symptoms generally begin in childhood or adolescence, but some individuals develop symptoms in mid-adulthood. The severity of symptoms varies greatly among individuals and even among family members with the disorder. The inheritance pattern in this disorder can be autosomal dominant, autosomal recessive and Xlinked. CMT1, caused by abnormalities in the myelin sheath, has five subtypes: CMT1A, CMT1B, CMT1C, CMT1D, and CMT1X. CMT type 1A is the most common form of CMT, affecting 50% of all CMT cases and 70% of patients with CMT1. CMT1A is associated with a genetic locus on chromosome 17p11.2 that Resulting from duplication of PMP22 gene. This gene encodes an integral membrane protein that is a major component of myelin in the peripheral nervous System. It should be noted that there is no cure for this neuropathy. However, treatments can help relieve symptoms, aid mobility and increase quality of life for people with the condition. Several techniques can be used for the molecular diagnosis of CMT1A such as RFLP-PCR, FISH, Multiplex PCR and MLPA. The MLPA method is a new technique for measurement of gene copy number. Many studies demonstrate that MLPA was able to detect duplication in all the patients with CMT1A. This review explains differential diagnosis of CMT1 from other neuromuscular diseases. Furthermore, it discusses advantage and disadvantage of the various techniques for the genetic diagnosis of CMT1. 124 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 204 Can mitochondrial encephalopathy, lactic acidosis and stroke-like episodes (MELAS) syndrome begin in adulthood, without significant previous history? Mostafa Almasi Dooghaee1, Mohammad Reza Motamed1, Masoud Mehrpour1, Yalda Nilipour2 1-Department of Neurology, Iran University of Medical Science, Tehran, Iran 2-Pediatric Pathology Research Center, Mofid Children Hospital, Shahid Beheshti Medical University, Tehran, Iran BACKGROUND: Mitochondrial encephalopathy, lactic acidosis and stroke-like episodes (MELAS) is a mitochondrial metabolic disease with multisystem involvement which can cause stroke-like episodes and status epilepticus. CASE PRESENTATION: A-48-year-old female with history of early fatigability, migraine-type headaches and bilateral sensory-neural hearing loss presented with two episodes of serial seizures. On admission she was affected by Wernicke aphasia and then right hemiparesis. Investigations showed elevated arterial lactate and ragged red fibers on muscle biopsy. CONCLUSION: Several cases of adult-onset MELAS syndrome were reported. This syndrome should be considered in patients with stroke-like events in adults without cerebrovascular risk factors and difficultto-treat seizures. 125 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 HEADACHE 126 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 205 Frequency of migraine headache precedence in patients with ischemic stroke referred to Farshchian hospital during 2012-2014 Mehrdokht Mazdeh, Sahar Rasooli Farshchian Hospital of Hamadan, Hamadan University of Medical Sciences, Hamadan, Iran BACKGROUND: An association between migraine and ischemic stroke has been observed for many years but the exact mechanisms by which migraine can lead to stroke are currently still under investigation. METHODS: In a descriptive cross-sectional study we evaluated all patients with ischemic stroke who had been hospitalized in Farshchian hospital from October 2012 to October 2014. Life time history of Migraine headache was diagnosed according to the International Classification of Headache Disorders (ICHD-II). All the data were put into questionnaire and compared with X2 and one way ANOVA test and by using SPSS 16 software. RESULTS: Frequency of migraine headache in 323 patients with ischemic stroke hospitalized was 11.2% (n=36). Migraine headache in female group (8.1%) and participants who were >60 years old (7.1%) was more common than male group and the other age groups. Compared with participants without headache, migraine and non-migraine headache have no significant correlation with ischemic stroke. Also there was no significant correlation between migraine headache and location of lesion in ischemic stroke patients. CONCLUSION: in our study no significant correlation between ischemic stroke, location of WML and migraine headache was noted. Migraine headache in female group (8.1%) who were >60 years old (7.1%) was more common than male group. More research is necessary in large population-based samples to more fully understand the effects of migraine headaches, both with and without aura therewith within a long period is recommended. 127 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 206 A comparison between the efficacy of pharmacological treatment and pharmacological treatment plus biofeedback in prevention and treatment of migraine headache attacks Ghoreishy Abdoreza, Ghoreishi Abolfazl, Tehrani M.R.H Department of Neurology, Zanjan University of Medical Sciences, Zanjan, Iran BACKGROUND: Migraine is an occasional headache which is manifested by neurological and digestive signs and changes in autonomic nervous system. WHO introduces migraine as the first among 20 debilitative disorders. Treatment of migraine headaches can be achieved via two modes of treatment: pharmacological and non pharmacological. PURPOSE: The purpose of this study which was carried out at Zanjan Vali-e Asr Hospital in 2012-2013, was to compare the effects of Biofeedback vs Pharmacological treatments to put forward the best one for migraine headaches. METHODS: 86 subjects referred to the neurology and psychological clinic of Vali-e Asr Hospital diagnosed with migraine by a neurologist and psychologist a according to HIS criteria were randomly entered into this study. Then, they were plugged into 2 separate groups; one group was labeled as pharmacological group and the other as Biofeedback and pharmacological group. RESULTS: Many of the individuals in both groups were between 31-45 years old (60.5% and 41.9%). Females were the dominant gender (90.7% in the case group and 81.4% in the control group) and the difference in groups was not statistically significant. The history of headache was more than 1 year in most participants (67.4% in the case group and 51.2% in the control group). The pulsatile headache was the most frequent. In both groups, most participants never had met a doctor to take painkillers until the time of our study (60.5% in the case group and 69.8% in the control group). These differences were not statistically significant. During the treatment until week 8, the reduction rate in the frequency of attacks, severity of attacks, MIDAS score and the need to use drugs was significantly higher in biofeedback group, but in week 10 (P value=0.026,0.311,0.371,0.192) and week 12 (P value=0.035,0.488,0.118 and 0.0001), the reduction was not significant. Concerning the reduction in the frequency of attacks, the difference was significant. Meanwhile, the average of frequency of attacks in the case group was 2.68 and in the control group was 1.65. CONCLUSION: Biofeedback and pharmacological treatment provides more rapid response than only pharmacological treatment while simultaneously it is more effective in the treatment of frequency of attacks. However, its effect on the reduction of headache severity and other consequent disabilities reaches to equal levels in both groups after a while. 128 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 207 CADASIL: Report of a family and review Mazyar Hahemilar, Masoud Nikanfar, Dariyush Savadi Oskoui, Sheida Shaafi Neurology Department, School of Medicine, Tabriz University of Medical Sciences, Tabriz, Iran A 33-year-old man presents to our outpatient clinic with a complaint of a chronic paroxysmal headache of moderate to severe severity since 3 years ago. His family history is negative for any type of chronic headaches. He has typical visual auras before his headaches. The neurological examination is unremarkable. A brain MRI is requested to rule out the secondary headache disorders shows T2 and FLAIR hyper-intensities diffuse in cerebral white matter and circumscribed subcortical lesions predominantly within the centrum semiovale, thalamus, and basal ganglia, suggestive of small infarcts. His father who died at the age of 59 following repeated strokes had multiple bouts of unresolved vomiting. His mental status had declined significantly when he died. The patient’s brother recently presented with a mild right hemiparesis and his brain MRI showed changes similar to his brother. Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is an inherited, autosomal dominant condition with high penetrance and varying expression. It is an important cause of protracted disability in young adults, with recurrent strokes, psychiatric dysfunction, and dementia. Although some families were identified in the 1950s, the syndrome was characterized and named only in 1993. The prevalence remains unknown, but numbers are increasing in parallel with wider medical recognition. In this report we discuss a family of three cease of CADASIL and review this disease in brief. 129 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 208 Pharmacological treatment for migraine headache based on evidence based medicine Abbas Ghorbani Neurology Department, Isfahan University of Medical Sciences, Isfahan, Iran PURPOSE: We tried to find what pharmacologic therapies are oven effective for migraine prevention. METHODS: We reviewed published studies from June 1999 to May 2014 to classify available medications for migraine prevention. RESULTS: The search strategy used the MeSH term “headache” and a published search strategy for identifying randomized controlled trials (RCTs) published between June 1999 and May 2007. Classification of migraine preventive therapies as the following items: Level A: Medication with establish efficacy (>2 Class trials) Level, B: Medications are probably effective (1 Class I class II studies Level, C: Medications are possibly effective (1 Class II study), Level U: Inadequate conflicting data support or refute medication use. Recommendation: Level A) The following medications are established as effective and should be offered for migraine prevention: Antiepileptic drugs (AEDs): divalproex sodium, sodium valproate, topiramate. Beta-Blockers: metoprolol, propranolol, timolol Triptans: frovatriptan for shortterm MAMs prevention. Level B) The following medications are probably effective and should be considered for migraine prevention: Antidepressants: amitriptyline, venlafaxine. Beta-Blockers: atenolol, nadolol Triptans: naratriptan, zolmitriptan for short term MAMs prevention. Level C) The following medications are possibly effective and may be considered for migraine prevention: ACE inhibitors: lisinopril Angiotensin receptor. Beta-blockers: candesartan. Alpha-Agonists: clonidine, guanfacine. AEDs: carbamazepine. Beta-Blockers: nebivolol, pindolol. Level U) Evidence is conflicting or inadequate to support refute the use of the following medications for migraine prevention: AEDs: gabapentin. Antidepressants: Selective serotonin reuptake inhibitor/selective serotonin-norepinephrine reuptake inhibitors: fluoxetine, fluvoxamine. Tricyclics: protriptyline. Antithrombotics: acenocoumarol, coumadin, picotamide. Beta-Blockers: bisoprolol. Calcium-channel blockers: nicardipine, nifedipine, nimodipine, verapamil Acetazolamide Cyclandelate. Level A negative. The following medication is established as ineffective and should not be offered for migraine prevention: • Lamotrigine Level B negative. The following medication is probably ineffective and should not be considered for migraine prevention: • Clomipramine. RECOMMENDATIONS FOR FUTURE RESEARCH: Although many preventive therapies reviewed herein are rated as Level C or U on the basis of the quality of evidence available, for some treatments extensive clinical experience supports a possible role in migraine prevention. Many of the older approaches to treating episodic migraine lack the financial justification or high-quality clinical study because they are not currently patentable drugs or otherwise do not promise a financial return for the cost of a major study. Until such treatments can be accurately studied practitioners are cautioned not to discount these agents because Class I prospective clinical studies are lacking. A case-by-case evaluation of these agents as treatment options is prudent. Future direction should include validating these initial clinical observations in scientifically sound RCTs. 130 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 209 The efficacy of Topiramate administration in benign paroxysmal torticollis of infancy: report of four cases with successful treatment Omid Yaghini, Negin Badihian, Shervin Badihian Child Growth and Development Research Center, Isfahan University of Medical Sciences, Isfahan, Iran BACKGROUND: Benign paroxysmal torticollis (BPT) is a rare paroxysmal dyskinesia and one of the childhood periodic syndromes presenting with recurrent stereotypic episodes of torticollis usually accompanied with some of the non-headache features of migraine such as vomiting, ataxia. Although the nature of the disease may seem to be benign, its recurrent episodes may mimic the attacks of epilepsy and expose the infant to unnecessary hospitalization and side effects of inappropriate medications. There is no approved medication for the disease yet though very limited studies has suggested Cyproheptadine which is not confirmed to be effective for these patients and has limitation to be used in children under 2 years. CASE PRESENTATION: We report four patients that showed successful response to the treatment with Topiramate and their episodes stopped to occur. Considering the underlying relation of BPT with migraine, satisfying response of our cases to Topiramate and the safety of this medication in neonates and children, Topiramate seems to be an effective and safe medication in reduction and elimination of BPT episodes. Also one of our cases (patient 4) confirms this finding by showing an explicit dependence in the regularity and duration of her attacks with Topiramate. CONCLUSION: Topiramate seems to be an effective medication in prophylaxis of BPT episodes. Further studies and clinical trials need to be done. 131 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 210 Migraine in Iran: A systematic review of literature from 2000 to 2014 Hassan Khani, Fariba Ezazi, Mahsa Kowsari, Mahnaz Najarian, Amaneh Ghorbani Iranian Applied Research Center for Public Health and Sustainable Development (IRCPHD), North Khorasan University of Medical Sciences, Bojnurd, Iran BACKGROUND: Migraine is a chronic neurological disorder and attacks are usually unilateral and mostly pulsating. This disease occurs in about 10% of the general population and affects their quality of life and performance. PURPOSE: The purpose of this study was to investigate the epidemiology, clinical and pharmacological interventions for the treatment of patients with migraine. METHODS: A literature review of articles published in the Persian Language by Iranian researchers from 1 January 2000 up to 30 December 2014 was conducted using the Scientific Information Database (through SID). The headings Migraine, chronic headache, used to execute the search. RESULTS: The results suggest that most patients with migraine signs include nausea, vomiting, photophobia, noise aversion, unilateral and bilateral headaches, the most important factors in the occurrence of migraines, insomnia, fatigue, stress, food greasy, fragrance, climate change, anemia, condiments is. On the other hand, the prevailing epidemiological indicators can be more migraine prevalence in the age range 15-45 years, women and educated people mention. In the study conducted by sodium valproate and Anala Preiļi reduce further attacks of migraine have been sought. The questionnaire used to identify patients with migraine has been studied in the literature include: demographic and headache questionnaire IHS, MIDAS and has several questionnaires. Descriptive studies and case studies based on questionnaires and were classified. CONCLUSION: It seems self-care training, stress management training to identify patients aged 15-5 years, new pharmacological interventions can help in reducing the risk of migraines. 132 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 211 Study of acetazolamide effect on severity, frequency and duration of cough headache Abolghasem Rahimdel, Mehdi Heidari, Samaneh Rahimdel Department of Neurology Shahid Sadoughi University, Yazd, Iran BACKGROUND: Cough headaches are an a type of headache triggered by coughing, sneezing, laughing, crying or any act which causes pressure on pain-sensitive structures in the head following the Valsalva maneuver. Any medication or practice that reduces the production of cerebrospinal fluid or accelerates its rate of absorption is effective in the treatment of such headaches. The aim of this study was to compare the effect of acetazolamide comparing to placebo in treatment cough headache. METHODS: This is a before-after clinical trial with simple sampling. This study performed with 20 patients who had cough headache with our studies criteria. At first patients had been treated by placebo during 3 months then they have not used any drugs during 1 month. Patients had been treated acetazolamide during 3 month as placebo duration. They were visited every month and evaluated by questionnaire of study. This questionnaire consists of different questions of cough headache aspects such as severity, frequency, duration, associated symptoms, and adverse laboratory changes. Patients’ questionnaire were been gradually completed. RESULTS: In this study, no statistically significant differences in side effects were found between acetazolamide and placebo in patients. CONCLUSION: Acetazolamide is more effective than placebo in treatment of intensity, frequency and duration of cough headache. 133 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 212 Comparative study of serum magnesium levels in migraine patients and normal subjects Fariborz Khorvash, Fatemeh Esteki, Ahmad Chitsaz, Majid Ghasemi Isfahan Neurosciences Research Center, Isfahan University of Medical Sciences, Isfahan, Iran BACKGROUND: Migraine has been known as one of the common diseases in all communities and especially in our society. So far, several studies have been conducted regarding the etiology and epidemiology of this disease that some of them suggest the association between migraine and serum magnesium levels. But these studies had contradictory results. Until now, we didn’t see any study in this regard, in Iran. So, this study aimed to compare the serum magnesium levels in migraine patients and normal subjects without migraine. METHODS: This investigation was a case control study conducted at the Alzahra medical center in 2013. Participants were included 55 patients with the migraine who referred to the Neurology Centre and 55 normal subjects without migraine referred to other departments of Alzahra. Two groups were matched for age and sex. To determine serum levels of magnesium, 5 ml of venous blood was taken from the patients and was sent to the laboratory. Also, the demographic information of all participants such as age, sex, history of migraine, headache intensity, headache duration and frequency were asked with a questionnaire and collected. Data were analyzed by SPSS 22 software. RESULTS: The mean of serum magnesium levels in patient and control groups were 43.0±73.1 mg/dl and 3.0±12.2 mg/dl, respectively. The serum magnesium levels were significantly lower in the migraine patients compare to the control group (p<0.001). Also, in 28 patients with migraine and 5 subjects in the control group the serum magnesium levels were seen lower than normal (49.1% versus 9.1%). And the frequency of magnesium deficiency in patients was significantly higher than control group (p<0.001). CONCLUSION: Migraine patients faced with the shortage levels of magnesium and due to the safety, the low cost of this mineral and its beneficial effect on the other physiologic reactions, its usage is recommended in these patients. Also, according to our findings approximately 10% of the general population has magnesium deficiency. In this regard, it is necessary to carry out more investigations to remove Magnesium deficiency in the general population, especially vulnerable groups such as pregnant females and children. 134 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 213 Comparison of the somatoform dissociation, fatigue severity and pain behavior in patients with migraine headache and healthy individuals, and its relationship with coping strategies Abolfazl Atalu, Ghasem Fattahzade, Vida Aghazae Ardebil University of Medical Science, Ardebil, Iran BACKGROUND: Migraine is a common disorder with mild to severe recurrent headaches with an unexplained pathology and has several physiological, psychological and social side effects. About 20 percent of people experience the disease in their lifetime. It is believed that genetic and environmental factors play a role in migraine. PURPOSE: The purpose of this study was comparison of somatoform dissociation, fatigue severity and pain behavior in patients with migraine headache and healthy individuals, and its relationship with coping strategies. METHODS: This study was a comparative study. The study population included all patients with migraine who referred to Alavi Hospital in Ardabil in 2014. The number of participants was 120, which was selected by simple random sampling, as well as 120 healthy subjects were selected. Data collection and analysis was according to the somatoform dissociation questionnaire (SDQ-20), fatigue intensity scale, pain behavior scale and coping strategies was used. For data analysis, the mean, standard deviation and T-Test and Pearson correlation test was used. RESULTS: This study showed that the comparison of the somatoform dissociation in migraineur and healthy subjects was significant (P value <0.0001). Also in pain behavior scale, help searching subscale and pain compliant was significant, and avoidance subscales (p value <0.151) was not significant between the two groups. Comparison of fatigue intensity in patients with migraine and control group was meaningful (P value <0.05). The results showed a statistically significant and positive correlation between all three scale of somatoform dissociation, fatigue severity, pain behavior and coping strategies (P value <0.05). CONCLUSION: This study showed that the average comparison of the somatoform dissociation, fatigue intensity, pain behavior and coping strategies in patients with migraine and control groups was significant. Also significant statistical and positive correlation between all three scales of somatoform dissociation, fatigue severity, pain behavior and coping strategies in patients with migraine and healthy individuals was observed. These symptoms seem to play an important role in this disease. The evaluation and attention to these essential factors in the treatment of migraine headache is warranted. 135 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 214 Evaluation the effect of aerobic training on selected physiological factors in patients with migraine Ahmad chitsaz, Vazgen Minacians, Freshteh Karimi Isfahan University of Medical Sciences, Isfahan, Iran BACKGROUND: Migraine is complex disorder of the nervous system related to carotid blood vessel vasodilation of intracranial blood vessels around the brain and stimulated the sensory nerves, trigeminal pain pathways. This study investigates the effect of aerobic training on selected physiological factors in migraine headache. METHODS: This was a semi experimental trial. Subjects included 22 women with migraine, the age range of 22 to 53 years who non randomly were selected and divided into experimental and control groups. The experimental group consists of 13 patients with migraine and participates in an aerobic exercise 3 times a week, 60 minute, for 12 weeks. RESULTS: After 12 weeks aerobic exercise there was a significant reduction in headache severity, calcitonin gene related peptide and fat percent and increase in maximal oxygen uptake, flexion and extension of neck, lateral flexion, range of motion, flexion and extension of shoulder in experimental group. CONCLUSION: The findings show that aerobic exercise can be an effective treatment for migraine headache. 136 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 MULTIPLE SLCEROSIS & NEUROIMMUNOLOGY 137 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 215 Updates on treatment optimization in multiple sclerosis Mohammad Hossein Harirchian Tehran University of Medical Sciences, Tehran, Iran Thanks to the vast investigations in recent years, the treatment of multiple sclerosis has become possible with disease-modifying therapies (DMTs) which have had a significant impact on those living with this disease. Unfortunately, these drugs are not curative and many patients with multiple sclerosis continue to have relapse or progression in spite of treatment. Besides, several adverse reactions have been reported with these agents, usually more serious and frequent in more efficient agents. In this regards the DMTs have been categorized in escalating categories and it is now important to pay attention on monitoring the results of the chosen therapy and deciding whether or not a patient has compliance for regular use of drug and is responding well to treatment. Several recommendations have been considered on how neurologists can assess the status of patients on DMTs and decide when it may be necessary to modify treatment in order to optimize outcomes. In this paper recent updates on treatment optimization in multiple sclerosis have been discussed. 138 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 216 Frequency of first clinical manifestations in Multiple sclerosis patients in clinics of neurology in Hamadan, IRAN during 2013-2014 Mehrdokht Mazdeh, Amin Elahi Far Farshchian Hospital of Hamadan, Hamadan, Iran BACKGROUND: Multiple sclerosis (MS) is one of the most common neurologic diseases which has a growing prevalence. This disease is common among the young population and causes them sever neurological disability. Early diagnosis and treatment can reduce the number of attacks and their severity in patients and plays an important role in enhancement of patients’ health level and their quality of life. As the primary clinical manifestations of MS are variable and nonspecific, and also different studies statistically have declared different comments about them, so in this study the prevalence of each possible primary clinical manifestation in MS patients of Hamadan is reviewed on the basis of age, sex and the type of clinical manifestation. METHODS: In this study 500 MS cases that were referred to neurologic clinics and MS institute of Hamadan and had the entrance criteria were studied and a questionnaire including demographic information and most common primary clinical manifestations was completed for each of them. After that, the collected data was analyzed by SPSS 16 software. RESULTS: In this study 394 patients (78.8%) were female and 106 of them (21.2%) were male. Study population had a range of 20-40 years old in their age. Mean age in onset of MS was 29.4±8.7 (range of 1162 year). The most common primary clinical manifestations of MS were visual symptoms in 31.6%, sensory symptoms in 19.8%, balance symptoms in 16.7%, and motor symptoms in 13.8% of the patients, respectively. No significant difference was seen prevalence of primary clinical manifestations between males and females. CONCLUSION: In this study, visual symptoms (optic neuritis and diplopia) were the most common primary clinical manifestations in all age ranges of the study population of MS patients followed by sensory symptoms as the second common primary clinical manifestations. As a conclusion, these results show the necessity of medical team alertness including general physicians, neurologists and ophthalmologists about early diagnosis of MS. It is recommended to perform studies with more extended population involved in order to have a more reliable comparison between the prevalence of MS clinical manifestations on the basis of their age, sex and location. 139 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 217 Copper, Lead, Zinc and Cadmium Status in Serum of Multiple Sclerosis Patients in the comparison with healthy peoples by polarography in Iran Ghoreishy Abdoreza1, Mehran Mohseni2, Raziyeh Amraei2 1-Department of Neurology, Zanjan University of Medical Sciences, Zanjan, Iran 2-Food & Drug Department, Faculty of Pharmacy, Zanjan University of Medical Sciences, Zanjan, Iran Multiple sclerosis (MS) is the most common disease caused by an inflammatory demyelinating process in the central nervous system, characterized by disseminated demyelination of nerve fibers of the brain and spinal cord. MS is a leading cause of disability in young adults with considerable disability and socioeconomic consequences. Globally, the average estimated prevalence of MS is 30 per 100000. In Iran, prevalence of MS is 20 per 100000 in a year. The cause of MS is still unknown. It is believe that, the disease is triggered by as-yet-unidentified environmental factor(s) in a person who is genetically predisposed to respond. It seems that, environmental exposure to heavy metals maybe associated with higher incidence of MS. In this work, we found a possible relationship between serum zinc, cadmium, lead and copper levels and development of MS. The serum levels of zinc (Zn), cadmium (Cd), lead (Pb) and copper (Cu) were measured in 50 Iranian patients with MS and 50 healthy person as as control group. They were matched on age, sex, race, smoking and drinking status. After sample preparation serum concentrations of zinc, cadmium, lead and copper were determined by polarography. Significantly higher serum Cu, Zn and Cd levels were found in the MS patients compared with the controls (p<0.05). There was no significant difference between the serum Pb levels of patients and controls (p>0.05). Serum levels of Zinc, cadmium and copper were significantly higher in patients with MS compared to controls (p<0.05). No significant association was found between serum lead levels of multiple sclerosis patients compared to controls (p>0.05). 140 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 218 Anti-N-methyl-d-aspartate-receptor encephalitis: case report and literature review Fariborz Rezaee Talab, Ali Ghabeli Juibary Student Research Committee, Faculty of Medicine, Mashhad University of Medical Sciences, Mashhad, Iran Anti-N-methyl-d-aspartate-receptor (NMDA-R) encephalitis is a newly described autoimmune disorder, often paraneoplastic in nature, presenting with complex neuropsychiatric symptoms and identification of the symptom complex is the key to diagnosis. Diagnosed serologically, this disorder is frequently responsive to immunosuppressant therapy. We herein report the case of a 56-year-old man with NMDA-R encephalitis presenting with bilateral ophthalmoplegia and spastic tetraparesis. His symptoms initiated two months before admission. Neurological examination showed mild consciousness disturbance and bilateral ophthalmoplegia, spastic tetraparesis with limbs hyperreflexia on admission. Cerebrospinal fluid samples showed mild pleocytosis and high protein content. CSF examination for herpes simplex virus and mycobacterium tuberculosis by polymerase chain reaction method was negative. Brain MRI disclosed small subcortical hypersignal lesion in the FLAIR and T2 weighted images. Anti-NMDA-R antibody was detected in the serum. The patient received IVIG and admitted to intensive care unit but unfortunately died two weeks after admission. 141 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 219 Melatonin can improve inefficient oxidative stress defense enzymes in peripheral blood mononuclear cells from patients with relapsing-remitting multiple sclerosis Solaleh Emamgholipour1, Mohammad Ansari1, Arash Hossein-nezhad2, Mohammad Ali Sahraian3, Fatemeh Askarisadr4 1-Department of Biochemistry, School of Medicine, Tehran University of Medical Sciences, Tehran, Iran 2-Miller School of Medicine, University of Miami, United States of America 3-MS Research Center, Neuroscience Institute, Tehran University of Medical Sciences, Tehran, Iran 4-Shahid Beheshti University of Medical Sciences, Tehran, Iran BACKGROUND: Oxidative stress has a crucial role in pathogenesis of multiple sclerosis (MS). Melatonin possesses a central role in modulation of oxidative stress pathways. The purpose of present study was to evaluate and compare the effect of melatonin on expression and activity of sirtuin1 (SIRT1), Manganese superoxide dismutase (MnSOD) and catalase in peripheral blood mononuclear cells (PBMCs) from patients with relapsing-remitting multiple sclerosis (RRMS) and healthy subjects. METHODS: This study was performed on twelve RRMS patients and fourteen healthy subjects (women with 20-40 years old). PBMCs were isolated and treated with melatonin (one millimolar) for 12 hours. Gene expression and activity of SIRT1, MnSOD and catalase were evaluated in PBMCs of controls and patients. RESULTS: Before melatonin treatment, the expression and activity of catalase was higher in patients, which was along with a decreased activity and expression of MnSOD and Sirt1 activity. We found that melatonin significantly increases activity and mRNA expression of SIRT1, MnSOD and catalase in patients. Pearson correlation analysis showed a significant correlation between SIRT1 activity with catalase and MnSOD activity in healthy subjects before melatonin treatment, while SIRT1 activity had no correlation with activity of MnSOD and catalase in patients. After melatonin treatment, a significant correlation was observed between SIRT1 activity and catalase activity in PBMCs of both patients and healthy subjects. Also, in controls but not patients we found a significant correlation between SIRT1 activity and MnSOD activity in melatonin-treated PBMCs. CONCLUSION: Our findings demonstrate that melatonin can improve impaired oxidative stress defense in MS patients through upregulation of SIRT1, Mn-SOD and catalase. In addition, melatonin could partly improve interrupted regulatory mechanism related to SIRT1- mediated modulation of antioxidant defense in MS patients via restoring interrupted correlation between SIRT1 activity and catalase activity in PBMCs of MS patients. 142 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 220 miR-214 suppressing Th17 differentiation via inhibiting JAK-STAT signaling pathway in patients with relapsing remitting–multiple sclerosis patients Ahmadian-Elmi M1, Ghaedi K2,3, Bidmeski Pour A1, Nasr Esfahani MH3 1-Department of Biology, Faculty of Science, Razi University, Kermanshah, Iran 2-Division of Cellular and Molecular Biology, Department of Biology, Faculty of Sciences, University of Isfahan, Isfahan, Iran 3-Department of Cellular Biotechnology at Cell Science Research Center, Royan Institute for Biotechnology, ACECR, Isfahan, Iran BACKGROUND: Multiple sclerosis (MS) is one of the most prevalence autoimmune diseases in women than men with the myelin damage in the central nervous system. Studies revealed that TH 17 cells play a critical role in the pathogenesis, inflammation and autoimmunity of several autoimmune diseases such as MS. MicroRNAs are small conserved endogenous non-coding RNAs that can affect cellular function by regulating gene expression in post transcriptional manner. Recently, researchers interest to focus them as therapeutic targets. METHODS: We use in silico analysis to find how miR-214 can affect differentiation pathway of naïve T cells into TH 17 cells. So we investigated interaction of miR-214 and their validated and predicted targets in miRWalk database that especially expressed in lymph node and thymus. Ultimately to find signaling pathway enrichment analysis of miR-214 targetomes given list was imputed in the database annotation, visualization and integrated discovery (DAVID) online database, version 6.7. DAVID database outputs the results from Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis to recognize the mainly statistically related signaling pathways and molecular networks via miR-214 targetomes. RESULTS: Functional annotation tool of DAVID database specified several KEGG signaling pathway according of targetomes list of miR-214 which is statistically significant that pertain to imputed genes and including Prostate cancer, Neurotrophin signaling pathway, Endometrial cancer, Pancreatic cancer, Colorectal cancer and interestingly JAK-STAT signaling pathway for miR-214. CONCLUSION: According of our bioinformatics studies miR-214 can inhibit JAK-STAT signaling pathway by targeting STAT2, STAT3 and IL6R. So that can lead to suppress differentiation of TH17 cells by inhibiting expression of IL17A as a master transcription factor of TH 17 cells. However, we need to confirm our finding by in vitro and in vivo experiment. 143 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 221 miR-214 function in patients with multiple sclerosis based on in-silico methods Ahmadian-Elmi M1, Ghaedi K2,3, Bidmeski Pour A1, Nasr Esfahani MH3 1-Department of Biology, Faculty of Science, Razi University, Kermanshah, Iran 2-Division of Cellular and Molecular Biology, Department of Biology, Faculty of Sciences, University of Isfahan, Isfahan, Iran 3-Department of Cellular Biotechnology at Cell Science Research Center, Royan Institute for Biotechnology, ACECR, Isfahan, Iran BACKGROUND: Multiple sclerosis (MS) is a neurodegeneration and defective immune regulation diseases with the myelin damage in the central nervous system. Studies revealed that TH 17 cells play a key role in the pathogenesis, inflammation and autoimmunity of several autoimmune diseases including MS. IL-17 is a hallmark production in T helper 17 (TH 17) cells that recognized as pro-inflammatory cytokine. MicroRNAs are small endogenous non-coding RNAs that can affect cellular function by regulating post transcriptional gene expression. Recently, researchers interest to select them as therapeutic targets. METHODS: We use in silico analysis to find what microRNAs that they can affect differentiation of TH 17 cells from naïve T cells. So we candidate 64 genes that deregulated of them cause different autoimmune diseases. So our bioinformatics analysis indicated that 8 microRNAs such as miR-214 have strong interaction with some genes that play crucial roles in TH 17 cells development and differentiation. These data investigated from 10 databases. RESULTS: Our bioinformatics data demonstrated that miR-214 show deregulation in MS patients. Several genes such as STAT6, TSC1, mTOR act as positive regulators that inhibit naïve T cells differentiation into TH17 cells. So miR-214 has interaction with them and reduces their expression, therefore suppress TH17 differentiation. CONCLUSION: According of our bioinformatics studies miR-214 can be used as therapeutic targets to decrease progression symptoms of MS. However, we need to confirm our finding by in vitro and in vivo experiment. 144 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 222 Herbal Medicine and immunosuppressive drugs in multiple sclerosis Jamile Sadat Havaeji1, Mansore Vahhabzade2, Zeinab Vesali Jamshid1, Azam Moslehi3, Masoumeh Dolati1 1-Cellular and Molecular Research Center, Qom University of Medical Sciences, Qom, Iran 2-Qom Azad University of Medical Sciences, Qom, Iran 3-School of Medicine, Qom University of Medical Sciences, Qom, Iran Multiple Sclerosis (MS) is the most common chronic inflammatory disease of the central nervous system in young adults. It is Pathologically Known as infiltrating macrophages and autoreactive T cells, particularly in the white matter damage myelin. MS is dominated by inflammation, oxidative damage and cytokines injuries and Based on this understanding; the initial therapeutic strategies were directed at immune modulation and inflammation control. Although several immunomodulatory drugs are now available, mostly present significant side effects over the long-term use. And it seems that Current therapies are not sufficient. On the other hands there are researches on the herbal treatment of MS, but these drugs is overwhelming clinical evidence of the efficacy of herbal drugs. A number of herbal products are in use for their immunosuppressive effects. This capacity of herbs maybe had useful applications in immune-mediated disorders including autoimmune diseases and organ transplant rejection. Plants such as Salvia miltiorrhiza and Tripterygium wilfordii has been shown to reduce inflammatory cytokines and mediators, indicating their value in the treatment of acute graft rejections and autoimmunity. Herbal drugs decrease the level of inflammatory cytokines and subsequently cause reduction of neuroinflammation and improve remyelination in the spinal cord. Herbal Medicine has targeted antiinflammatory mechanisms to inhibit or slow down the disease progression. However studies indicate that Herbal Medicine has no serious side effect. But, further studies are needed to elucidate the involved possible mechanisms. 145 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 223 MS or not MS Nastaran Majdinasab Department of Neurology, Ahvaz Jundishapur University of Medical Sciences, Ahvaz, Iran Multiple sclerosis (MS) is the most common inflammatory demyelinating disease of the central nervous system in young and middle-age adults, but also affects older people. As a consequence there is an important role for MRI in the diagnosis of MS, since MRI can show multiple lesions (dissemination in space), some of which can be clinically occult, and MRI can show new lesions on follow up scans (dissemination in time). MS has a typical distribution of WMLs. This can be very helpful in differentiating them from vascular lesions. Typical for MS is involvement of corpus callosum, U-fibers, temporal lobes, brainstem, cerebellum and spinal cord. This pattern of involvement is uncommon in other diseases. In small vessel disease there may be involvement of the brainstem, but it is usually symmetrical and central, while in MS it is peripheral. One of the most common questions in daily radiology practice when we see an image is 'Do we have to think of Multiple Sclerosis? or are these white matter lesions the result of small vessel disease, as in a hypertensive patient? or should we think of more uncommon diseases? However the list of possible diagnoses of WMLs is long. This topic discuss about differential diagnosis MS based of MRI finding. 146 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 224 The Effect of Fluoxetine on Fatigue, Sleep quality, Depression and Clinical Status in Patients with Multiple Sclerosis FardinFaraji1, Shayan Amjadi2, Bahman Sadeghi3, Afsoon Talaie4 1-Department of Neurology, Medicine Faculty, Arak University of Medical Sciences, Arak, Iran 2- Students Research Committee, Arak University of Medical Sciences, Arak, Iran 3-Department of Social Medicine, Medicine Faculty, Arak University of Medical Sciences, Arak, Iran Iran4-Health Department, Islamic Azad University, Arak Branch, Iran BACKGROUND: Expression of the inflammatory cytokines which have been associated with fatigue is increased during MS. PURPOSE: The aim of the present study was to determine the anti-inflammatory effects of fluoxetine on fatigue in patients with relapsing remitting MS and also to survey the changes in sleep quality and depression. METHODS: In a triple-blind, placebo-controlled exploratory study, 75 patients with relapsing remitting MS were randomized to oral fluoxetine 20 mg or placebo daily for 24 weeks. Fatigue, sleep quality and depression evaluation performed at baseline and end of study period by assessing FSS (Fatigue Severity Scale), PSQI (Pittsburgh Sleep Quality Index) and BDI (Beck Depression Inventory). Clinical activity of MS was also studied by assessing EDSS (Expanded Disability Status Scale). RESULTS: Thirty seven patients in intervention group and 36 patients in placebo group completed the study. The number of patient with fatigue showed a significant decrease in the fluoxetine group in comparison with placebo group (p=0.001). Patients who received Fluoxetine showed a significant (p<0.05) improvement in sleep quality, and fluoxetine significantly improved depression severity in comparison with placebo (P<0.001). However treatment with placebo produced a significant (p<0.05) increase in the EDSS but there was no significant different in intervention group (p>0.05). A significant correlation was observed between changes in EDSS and FSS (P<0.023), BECK (P=0.014) and PSQI (P=0.014). CONCLUSION: This proof-of-concept study shows that fluoxetine tends to increase stability in clinical course in patients with MS. It was determined that fluoxetine reduced patients’ fatigue level and improved their sleep quality and their mood. Further studies with this compound are warranted. 147 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 225 Sleep quality and Depression in patients with Multiple Sclerosis in Arak in 2012 Fardin Faraji1, Shayan Amjadi2, Afsoon Talaie3 1- Department of Neurology, Medicine Faculty, Arak University of Medical Sciences, Arak, Iran 2- Students Research Committee, Arak University of Medical Sciences, Arak, Iran 3- Health Department, Islamic Azad University, Arak Branch, Iran BACKGROUND: Multiple Sclerosis (MS) is a common demyelinating disease of CNS. Depression and Sleep disorders are common in MS patients and effect on patients’ quality of life. PURPOSE: The aim of the present study was to determine prevalence of poor sleep quality and depression in patients with MS in Arak in 2012. METHODS: In a cross-sectional study sleep quality and depression severity evaluated in patient with MS during 3 months of study period by assessing Pittsburgh Sleep Quality Index (PSQI) and BECK Depression inventory (BDI) questionnaire. RESULTS: 99 patients (79 female and20 male) with MS were evaluated. Mean (SD) of age was 33.07(8.03). Mean (SD) of BECK score was 13.17 (8.96) only 38% of patients were not depressed. Mean (SD) of PSQI score was 5.77 (3.68) and poor sleep quality was observed in 52% of patients. CONCLUSION: This proof-of-concept study showed that 62% of patients with MS suffer from depression and low sleep quality was observed in 52% of patients. 148 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 226 Peripheral blood monocytes in multiple sclerosis patients and healthy controls Mehrdad Farokhi1, Masoud Etemadifar1, Maryam Sadat Jafary Alavi2, Sayyed Hamid Zarkesh-Esfahani3, Mohaddeseh Behjati4, Ali Rezaei5, Ali Amani Beni1 1-Department of Neurology, School of Medicine, Isfahan University of Medical Sciences, Isfahan, Iran & Multiple Sclerosis and Neuroimmunology Research Center, Isfahan, Iran 2-Department of Biology, Faculty of Sciences, University of Isfahan, Isfahan, Iran 3-Department of Biology, Faculty of Sciences, University of Isfahan, Isfahan, Iran 4-Heart Failure Research Center, Isfahan Cardiovascular Research Institute, Isfahan University of Medical Sciences, Isfahan, Iran 5-Department of Molecular Biology, Cell Biology, and Biochemistry, Brown University, Providence, Rhode Island, USA & Department of Neuroscience, Brown University, Providence, Rhode Island, USA BACKGROUND: Aberrant immune responses are evident in the pathogenesis of multiple sclerosis (MS) and it has been proposed that the spectrum of cytokines influence disease outcomes. Leptin and lipopolysaccharide (LPS) of gram-negative bacteria are both potent cellular stimulators for production of pro-inflammatory cytokines such as tumor necrosis factor-α (TNF-α). The aim of this study was to compare the TNF-α production by peripheral blood monocytes from MS patients with healthy controls. METHODS: Peripheral blood samples were stimulated with LPS or leptin. After blocking the Golgi apparatus, intracellular cytokine production was assessed using a monoclonal antibody against human TNF-α by the flow cytometry technique. Moreover, expression of TLR4 on the surface of monocytes was evaluated using flow cytometry. Plasma level measurement of cytokines was performed using enzymelinked immunosorbent assay. RESULTS: Intracellular levels of TNF-α were 16.80±8.21 and 16.52±8.23in MS patients and healthy controls which showed no statistically significant difference between them (P=0.850). Leptin-stimulated and LPS stimulated TNF-α production showed no significant difference between MS patients and the control group (P=0.263 and P=0.191, respectively). However, after treatment with leptin, a weak significant difference was shown between cases and control group (P=0.049).There were significant differences between cases and controls regarding serum levels of IL-6 and Toll-like receptor-4 (TLR-4) before and after stimulation with leptin and LPS, separately (P<0.05). CONCLUSION: Taken together, we cannot definitely conclude that TNF-α does not play an important role in pathogenesis of MS. However, other characteristics of monocyte activation such as IL-6 or TLRs can elucidate implication of peripheral blood monocytes in MS pathogenesis. 149 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 227 Serum level measurement of soluble IL-6 receptor and soluble glycoprotein-130 in relapsing remitting multiple sclerosis and neuromyelitis optica patients Mehrdad Farrokhi1,2, Ali Rezaei3,4, Ali Amani Beni1,2, Masoud Etemadifar1 1-Department of Neurology, School of Medicine, Isfahan University of Medical Sciences, Isfahan, Iran & Multiple Sclerosis and Neuroimmunology Research Center, Isfahan, Iran 2-Medical student, Faculty of Medicine, Isfahan University of Medical Sciences, Esfahan, Iran 3-Department of Molecular Biology, Cell Biology, and Biochemistry, Brown University, Providence, Rhode Island, USA 4-Departments of Neuroscience, Brown University, Providence, Rhode Island, USA BACKGROUND: Multiple sclerosis (MS) is a T-cell mediated autoimmune demyelinating disease of central nervous system that normally conduces to alternate neurological impairmentsfollowed by disability progression. Increased production of pro-inflammatory cytokines can be found during MS pathogenesis. It is well known that IL-6 is also a pro-inflammatory cytokine. This cytokine plays its role through an oligomeric membrane-bound receptor containing two subunits: IL-6R which especially binds to IL-6 and glycoprotein 130 which regulates the response of cell to IL-6 cytokine and also transduces signals that are producedthrough this receptor. PURPOSE: In this study we aimed to investigate levels of soluble IL-6 receptor (sIL-6R) and soluble glycoprotein 130 (sgp130) in serum of patients with relapsing remitting multiple sclerosis (RRMS) and neurmyelitis optica (NMO) and also healthy controls. METHODS: The study groups consisted of 61 RRMS patients and 31 patients with NMO. We also chose 59 healthy controls that were matched well in terms of age and sex. Serum level measurement of sIL-6R and sgp130 was performed using ELISA. RESULTS: The mean concentrations of sIL-6R and sgp130 of patients were significantly higher than healthy controls. Furthermore, serum levels of them in NMO patients were significantly higher than RRMS patients. In addition, serum concentrations of these two markers were significantly correlated with EDSS. CONCLUSION: We have found that IL-6 is involved in MS pathogenesis; especially in patients with NMO. Furthermore, this study suggested that soluble forms of IL-6 receptor can be served as markers of MS activity. 150 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 228 Increased serum level of IL-37 in patients with multiple sclerosis and neuromyelitis optica Mehrdad Farrokhi1,2, Ali Rezaei3, Ali Amani Beni1,2, Masoud Etemadifar1,Ebrahim Kouchaki4, Abolfazl Zahedi5 1-Department of Neurology, School of Medicine, Isfahan University of Medical Sciences, Isfahan, Iran & Multiple Sclerosis and Neuroimmunology Research Center, Isfahan, Iran 2-School of Medicine, Isfahan University of Medical Sciences, Isfahan, Iran 3-Department of Neuroscience, Brown University, Providence, Rhode Island, USA 4-Department of Neurology, School of Medicine, Kashan University of Medical Sciences, Kashan, Iran 5-School of Medicine, Kashan University of Medical Sciences, Kashan, Iran BACKGROUND: Multiple sclerosis (MS) is a common autoimmune disease of central nervous system in which neurodegenerative and inflammatory mechanisms cause alternate neurological impairments. Many inflammatory and anti-inflammatory cytokines were suggested as contributor in MS pathogenesis and the balance between these opposing cytokines can regulate MS severity. IL-37, an anti-inflammatory cytokine, is the most recently identified member of IL-1 family act as a natural inhibitor of innate immunity. However, the role of IL-37 in MS has not investigated so far. PURPOSE: In this study we aimed to measure serum level of IL-37 in patients with relapsing remitting multiple sclerosis (RRMS) and neuromyelitis optica (NMO). METHODS: In a case-control study, plasma was collected from healthy controls (n=49) and also patients with RRMS (n=22) and NMO (n=31). Serum level measurement of IL-37 was performed using enzymelinked immunoassay method. RESULTS: The serum levels of IL-37 were 247.46±74.02 and 312.00±86.72, and 114.63±20.58in RRMS and NMO patients and healthy controls, respectively, showing statistically significant difference between them (P=0.00). Furthermore, we found a positive correlation between serum levels of progranulin and EDSS of patients (r=+0.31 and P=0.00). CONCLUSION: In summary, the serum level of IL-37 was found to be significantly increased in MS patients compared to healthy controls. Furthermore, serum level of IL-37 was correlated with disease severity. This suggests that IL-37 may be part of a feed-back loop to control underlying inflammation in MS pathogenesis. However, further studies will be required to indicate exact role of IL-37 in MS pathomechanisms. 151 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 229 Serum level measurement of progranulin in relapsing remitting multiple sclerosis and neuromyelitits optica patients Ali Amani Beni1,2, Mehrdad Farrokhi1,2, Ali Rezaei3, Masoud Etemadifar1, Ebrahim Kouchaki4, Abolfazl Zahedi5 1-Department of Neurology, School of Medicine, Isfahan University of Medical Sciences, Isfahan, Iran & Multiple Sclerosis and Neuroimmunology Research Center, Isfahan, Iran. 2- School of Medicine, Isfahan University of Medical Sciences, Isfahan, Iran 3-Department of Neuroscience, Brown University, Providence, Rhode Island, USA 4-Department of Neurology, School of Medicine, Kashan University of Medical Sciences, Kashan, Iran 5-Faculty of Medicine, Kashan University of Medical Sciences, Kashan, Iran BACKGROUND: Multiple sclerosis (MS) is a complex autoimmune disease of central nervous system with unknown etiology and variable clinical evolution. Although the role of serum progranulin levels in the pathogenesis of MS remains unclear, it is well known that progranulin is involved in several physiological and pathophysiological process of CNS including modulation of neurite outgrowth, neuronal differentiation, and neuronal survival. PURPOSE: In this study we aimed to measure serum levels of progranulin in patients with neuromyelitis optica (NMO) and relapsing remitting multiple sclerosis (RRMS) in comparison with healthy control subjects. METHODS: In a case-control study, plasma was collected from healthy controls (n=49) and also patients with RRMS (n=122) and NMO (n=31). Serum level measurement of progranulin was performed using a sandwich ELISA method. RESULTS: The serum levels of progranulin were 62.34±16.13, 51.44±13.88, and 41.26±10.04 in NMO and MS patients and healthy controls, respectively, showing statistically significant difference between them (P=0.00). Furthermore, we found a positive correlation between serum levels of progranulin and EDSS of patients (r=0.42 and P<0.001). CONCLUSION: The present study demonstrated that progranulin is up-regulated in MS patients and our findings strengthen the evidence for progranulin being involved in pathogenesis of MS. However, further studies will be required to establish progranulin as an important marker for MS. 152 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 230 Epidemiological investigation of Neuromyelitis Optica in Khuzestan Province, South West Iran Davood Kashipazha, Seyed Ehsan Mohammadiany Nejad, Mostafa Azizi, Majid Jafari Department of Neurology, Golestan Hospital, Ahvaz Jundishapur University of Medical Sciences, Ahvaz, Iran BACKGROUND: Neuromyelitisoptica (NMO) is an uncommon neuro-inflammatory syndrome that has shown to be distinct from multiple sclerosis and associated with the autoantibody marker NMO –IgG. There are still only a few studies regarding the epidemiology of NMO in Iran. In the present study we tried to describe the epidemiology of NMO in Khuzestan as one of the densely populated regions in Iran. METHODS: A cross-sectional study was performed during the period 2013-2014. Multiple regional sources of data were used including hospital records, details from neurologists and MS society database. The diagnosis of NMO was based on clinical presentation, abnormal findings on neuro-imaging and serological tests. RESULTS: Fifty-one (51) Caucasian patients (36 patients with NMO and 15 with NMO-spectrum disorder) were identifiedwith a female/male ratio of 7.5:1. The crude prevalence of NMO was 1.1/100,000 population. The mean age at onset was 29.2±6.1 years and the mean duration of symptoms was 5±0.4 years. A majority of patients (60.8%) were classified as having mild disability (EDSS= 0-3.5). Among of 35 patients whose titer of NMO-IgGwas measured, 19 (54.2%) were seropositive. CONCLUSION: Our study suggests that NMO prevalence rate in South West Iran (Khuzestan Province) is much lower than that reported for MS prevalence rate (16.2/100000) and our patients had a lower age at onset presentation and milder course of the disease than western countries. 153 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 231 A metastatic ductal cell carcinoma following use of mitoxantrone Masoud Ghiasian, Mojtaba Khazaee, Mehrdad Afsharee, Sahar Moradi Department of Neurology, Hamadan University of Medical Sciences & Health Services, Hamadan, Iran A 38-year-old woman who was known case of multiple sclerosis from 6 year ago was candidate for mitoxantrone administration because progression of the lesions in brain and cervical MRI and clinical worsening. In the course of treatment she was stable with no progression of symptoms and sign. Until one month before the seventh and the last pulse, she came with intractable pain in the sternum region. In further evaluation metastatic skeletal lesions due to breast cancer was diagnosed. 154 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 232 Psychological Approach to the Diagnosis and Treatment of Sexual Dysfunction in Patients with Multiple Sclerosis Mahmoud Hedayatnejad University of Tehran, Tehran, Iran Multiple Sclerosis (MS) is a chronic inflammatory disease that affects the central nervous system. The most common age of onset is 20 to 45 and the ratio of infected women to men is 2 to 1. MS patients have numerous problems because it is a refractory disease and has gradual progression of the disability and severity of the symptoms. Some common symptoms of MS are Muscle Weakness, Muscle Spasms & Pain, Tremble, Difficulties with Balance, Emotional Symptomatology (Depression), Bladder and Bowel Difficulties, Visual & Hearing Problems, Dysarthria and Sexual Difficulties. Sexual dysfunction is very common in MS patients and is variable from 5% to 7% depending on the type of disease. Despite the high prevalence of these problems, due to culture and customs of society, it is less posed by the patient as a problem. However, because of timidity and modesty, teaching these concepts are often ignored. This dysfunction in women is appeared as Loss of Sexual Desire, Loss of Pleasure and Dyspareunia and in men as Erectile Dysfunction, Decreased libido and Fatigue. Such disruptions can be resultant from symptoms of disease with psychological nature including emotional symptomatology, stress and anxiety, feelings of inadequacy, drug side effects or can be directly related to damage of nerve receptors paths which have important role in the vital interplay of body such as sexual activity. Sexual activity is a complex phenomenon and is influenced by biological, psychological and social factors. One factor that has a significant role in sexual ties is that how a person sees themselves as male or female and what are their mental images from themselves? Feeling of being interesting and attractive will seriously change due to physical disability caused by MS. These patients feel that due to having MS, they cannot have a happy marital relationship. Treatment of these disorders in MS patients includes special treatment and problems associated with that treatment such as Emotional Symptomatology, Fatigue, Pain, Bladder and Bowel Difficulties, so on. This review, descriptive study and the results have indicated that psychologists, psychiatry and support measures and establishment of specific sexual counseling centers for MS patients are an important part of the rehabilitation program. For healthcare team, MS is considered as a crisis intervention and expert advice and interdisciplinary of neurologists, urologists, psychiatrists and clinical psychologist, MS specialist for medical programs management, career advice, and social worker is a serious necessity which enhances the biological, psychological and social life quality of these patients. At the end, it is noteworthy that human and its needs should be regarded by the holistic approach and his behavior should be perpended as a creature with various dimensions (Bio, Psycho-Social) and providing a successful treatment comprehensive program especially in patients with MS will be possible particularly with regard to the three factors mentioned above. 155 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 233 Basal Level of Hypothalamus-Pituitary-Adrenal Axis Hormones in Remission Period of Multiple Sclerosis Patients Arash Mosarrezaii‚ Neda Valizadeh‚ Nazila Azimi‚ Vahid Ghazizadeh Urumia Medicine University, Urumia, Iran BACKGROUND: MS (multiple sclerosis) is an autoimmune and degenerative disease of central nervous system. Several studies indicate to the role of HPA axis and stressful life events in the susceptibility to the disease. In this study‚ we investigated the activity of HPA axis and level of its hormones in these patients. METHODS: In this study 50 patients with clinically definite MS and in remission period‚ 10 patients during acute relapse and 20 healthy subjects were studied. No patients were receiving steroid or other immunomodulatory therapy during 3 months. Plasma cortisol and adrenocorticotropic hormone (ACTH) were measured using ELISA and radioimmunoassay respectively. RESULTS: In this study‚ 80 subjects were studied whose mean age was about: remission period (36.9±1.6) ‚ attack (30.4±3.5) and control (37.15±2.6). 54 subjects were female and 21 were male. Level of cortisol was respectively 25.24±1.42 ‚ 16.28±1.75 and 15.5±3.7 ng and level of ACTH was 10.16±1.31 ‚ 3.41±1.47 and 7.83±1.82. CONCLUSION: Cortisol levels in patients with remission period are higher than healthy control and attack groups and there is no difference between healthy control and attack groups. ACTH levels are also higher than two other groups. But Adrenocorticotropic hormone levels during the attack are less than healthy control group. The information available suggests the HPA axis activity can affect the incidence and prevention of attacks in multiple sclerosis. 156 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 234 What factors are associated with olfactory dysfunction in patients with multiple sclerosis? Mostafa Almasi Doghaee, Mohammad Roohani, Mohammad Ali Sahraeean, Hamid Reza Ezzati Department of Neurology, Faculty of Medicine, Iran University of Medical Sciences, Iran BACKGROUND: Impaired sense of smell has remarkable value in quality of life and has a great prevalence in some neurodegenerative diseases. In this study we assessed the olfactory dysfunction in patients with multiple sclerosis (MS) by means of sniff magnitude test (SMT). METHODS: A cross-sectional study was conducted on 48 patients with MS. After taking clinical history and performing physical examination, a questionnaire including demographic and clinical variables completed for each patient. The SMT was used for evaluation of olfaction. RESULTS: the olfactory dysfunction was found in 14.6% of patients, including 8.3% hyposmia and 6.3% anosmia. The older age, higher duration of MS and count of the admission in hospital, lower mini mental status examination score and type of secondary progressive MS had significant relationship with olfactory dysfunction. CONCLUSION: Olfactory dysfunction in patients with MS is associated to more severe disease and lower cognitive function. Thus olfactory function may use as a marker of severity of neurologic disability in these patients and routine screening of olfaction in workup of MS patients is recommended. 157 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 235 Effect of vitamin D on nitrite level in endothelial cell treated by sera from multiple sclerosis patients Leila Dehghani1,2, Vahid Shaygannejad1, Amirmohammad Abedini2 1-Isfahan Neurosciences Research Center, Alzahra Hospital, Isfahan University of Medical Sciences, Isfahan, Iran 2-Department of Medical Sciences, School of Medicine, Najafabad Branch, Islamic Azad University, Isfahan, Iran BACKGROUND: Multiple Sclerosis (MS) is a progressive neurodemyelinative disease in which neural sheath and endothelial cell (EC) can be affected. In brain, functional changes in ECs contribute to reductions in resting blood flow. Furthermore, vitamin D3 has beneficial effects on endothelial dysfunction. This study presents direct experimental evidence associating free radicals and endothelial apoptosis as a basis of MS pathogenesis and response to vitamin D3 therapy. METHODS: Human umbilical vein ECs (HUVECs) were treated with sera from MS patients and sera from healthy volunteers (each group, n=30). 1. cells were only treated by sera from MS for 24 h, 2. cells were treated by 1,25(OH)2D3 for 24 h and then sera from MS was added to these cells for another 24 h. 3. cells were exposed in the sera of MS for 24 h and then 1,25(OH)2D3 was added to these cells for another 24 h. In the fourth group, cells were treated by sera from healthy individuals for 24 h free radical level was determined by nitric oxide (NO) assay kit. Nitrite (NO2−) levels were determined in the culture supernatants. RESULTS: vitamin D3 prevented the production of Nitrite by the serum of patients. The mean±SD of NO2− concentration showed significantly greater levels of dissolved NO2/NO3 metabolite in the culture media of untreated HUVECs by vitamin D3 as compared with control, while the rate of NO significantly decreased when vitamin D3 was presented in culture both in the pretreatment and in the post treatment group. CONCLUSION: It could be concluded that EC treated with sera from MS patients activates apoptosis in HUVECs; this effect was reversed by vitamin D3 treatment. This can be proposed as a therapeutic approach for MS. In this study, we discovered that NO2 − concentration and were significantly higher in the HUVEC media treated by MS serum as compared with the control, and elevation levels of dissolved NO2/NO3 metabolite was significantly reduced by co incubation of vitamin D3 in the pretreatment and post treatment groups of serum. 158 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 236 Quality of Life in Iranian patients with Multiple Sclerosis: A systematic review of literature from 2000 to 2014 Hassan Khani, Yalda Rabbani, Amaneh Ghorbani, Ata Ghorbani Iranian Applied Research Center for Public Health and Sustainable Development (IRCPHD), North Khorasan University of Medical Sciences, Bojnurd, Iran BACKGROUND: Multiple sclerosis (MS) is a unique central nervous system inflammatory disease with a broad spectrum of clinical presentations, which are time- and disease progression-related. It usually affects young adults, with a female predominance of 3:1. Quality of life in patients with MS is an important outcome. There are many published studies about MS in Iran, but quality of life of MS patients is uncertain. PURPOSE: This paper reviews such studies to shed more light on the topics. METHODS: A literature review of articles published in the Persian Language by Iranian researchers from 1 January 2000 up to 30 December 2014 was conducted using the Scientific Information Database (through SID). The headings multiple sclerosis, quality of life, stress, anxiety, depression, health mental used to execute the search. RESULTS: Instruments were used to measure quality of life in multiple sclerosis patients. a) General Quality of Life Questionnaires: SF-36, SF-8, WHOQoL; b) Special Quality of Life Questionnaires for multiple sclerosis patients: MS-QoL-38, MS-QoL-58, MSIS-29; c) Psychology Determinants Questionnaires: Billings and Moos Questionnaire, Jaloos Questionnaire, Kohen Questionnaire, Coudron Questionnaire, Beck Depression Questionnaire, Beck Anxiety Questionnaire, Depression Anxiety Stress Scale (DASS-21, DASS-42), Mental Health Questionnaire (GHQ), Endler & Parker Questionnaire, d) Chronic Patients Careers: Ferel and Grant Questionnaire and several researcher made Questionnaire. Findings categorized on the basis of Questionnaires and type of studies. In 16 descriptive studies shown quality of life in MS patients was significantly low from general population. In 34 interventional studies shown after interventions were significantly quality of life promotions in MS patients. CONCLUSION: At seems that quality of life among Iranian MS patients is Inappropriate. We suggest neurologists should be In addition to drug therapy, Use of health education and promotion programs included self-care, yoga and exercise, stress management, emotional release, social supports, family supports for quality of life promotion. 159 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 237 Socio-demographic, risk factors and clinical characteristics of multiple sclerosis in Isfahan Omid Mirmosayyeb1,2, Mahdi Barzegar1,2, Zahra Heidari3, Vahid Shaygannejad1,2 1-Department of Neurology, School of Medicine, Isfahan University of Medical Sciences, Isfahan, Iran 2-Isfahan Neurosciences Research Center, Isfahan University of Medical Sciences, Isfahan, Iran 3-Department of Epidemiology and Statistics, School of Health, Isfahan University of Medical Sciences, Isfahan, Iran BACKGROUND: Multiple sclerosis (MS) is a chronic disease of the central nervous system (CNS) and in many countries it is the most important cause of non-traumatic neurologic disability in young adults. Inflammation, demyelination and axonal damage are pathological trademarks contributing to the distinctive multifocal CNS lesions seen in MS. MS seems improbable to result from a single causal event; instead, the disease appears to develop in genetically predisposed populations as a consequence of environmental contacts. Whilst its particular etiology remains mysterious, a number of risk factors have been described; including female sex, low sunlight exposure, low vitamin D levels, Epstein Barr virus infection, and smoking. PURPOSE: Our aim was to investigate demographic and clinical factors in MS in Isfahan. METHODS: In this cross-sectional study which was conducted from 2013-2014 data of 1473 MS patients referred to MS clinic of Kashani Hospital collected. All the cases were assessed by a neurologist and included in the study whenever they met the McDonald diagnostic criteria. Results were presented as mean±error of mean (SEM) for quantitative variables and were summarized by number (percent) for qualitative variables. Independent t-test and Analysis of variance (ANOVA) was used for comparing the Expanded Disability Status Scale (EDSS) score among studied groups. Bonferroni post hoc test was used for pairwise comparisons. P <0.05 was considered as statistically significant level. RESULTS: The database is composed of 1473 patients with definite MS with the mean age of 35.06±0.25.Relapsing-Remitting (RR) course was the most type (84.0%) of MS among patients. The female to male ratio is 3.75 with78.9% of females MS patients and 21.1% males. Patients were divided in three groups according to their disability as measured by the EDSS. Most patients (86.1%) had an EDSS of 3.5 or less. Significant relations were seen between EDSS and gender, marital status, employment status, education level, MS type and smoking. There weren’t significant associations between EDSS and positive family history or psychological stresses. CONCLUSION: MS risk factors and characteristics reported contrarily in population based studies. This study demonstrates that majority of MS patients are 20-40 years-old females who develop Relapsing Remitting Multiple Sclerosis (RRMS), though males who had Secondary progressive Multiple Sclerosis (SPMS) developed more disabling course. A past history of smoking, seizures and respiratory disorders made patient’s experience more debilitating MS. More investigates particularly accompanied with patient’s follow up need. 160 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 238 Multiple Sclerosis and Androgenic Hormones in Pregnancy Omid Mirmosayyeb1,2, Mahdi Barzegar1,2, Leila Dehghani1, Vahid Shaygannejad1,2, Nahid Eskandari3 1-Isfahan Neurosciences Research Center, Isfahan University of Isfahan, Isfahan, Iran 2-Department of Neurology, Alzahra Hospital, IUMS, Isfahan, Iran 3-Department of Immunology, Medical University of Isfahan, Isfahan, Iran BACKGROUND: Multiple sclerosis (MS) is an inflammatory, demyelinating neurological disease that causes severe disability. MS is known to have a hormonal component. Women are more susceptible than men, even though the prognosis is less good for males. Pregnant women suffering from MS do better during pregnancy. So, the aim of this study was to evaluate the role of androgens on MS. METHODS: The studies (up to July 2014) with the association between MS and androgenic hormones included in the analysis. RESULTS: Most studies showed that MS has no negative effects on pregnancy and fetus. It confirms that MS does not necessitate the termination of pregnancy. It showed that a 70% decrease in attack frequency during the third trimester as compared to 1 year before pregnancy. In contrast, the attack increased in the postpartum stage. Due to increase of estrogen level during pregnancy, CD4 and CD25 of immune cells rise, so dominancy of Th2 to Th1 prevents the autoimmune response in MS. Others showed progesterone increase demyelination and protect myelin sheaths. Some studies showed a helpful effect of estriol treatment on MRI in MS. CONCLUSION: Elevation of androgenic could have a positive effect on Th1/Th2 ratio. More clinical and population-based studies need to clarify impact of Pregnancy situation on MS. So, this could be as a key to use as a treatment for MS diseases. 161 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 239 Investigation of PPAR gamma gene expression in peripheral blood mononuclear cell of multiple sclerosis compared to healthy control subjects Emamgholipour S, Askarisadr F, Shojaie M, Ansari M Loghman Hospital, Tehran, Iran BACKGROUND: Peroxisome proliferator-activated receptor gamma (PPARγ), a ligand-activated transcriptional factor involved in the regulation of glucose and lipid metabolism, has gained interest as a potential therapeutic target in multiple sclerosis (MS) due to its potent immunoregulatory properties and the therapeutic efficacy of its ligands in experimental autoimmune encephalitis (EAE). Elevated expression of PPARγ has been observed in the spinal cord of EAE mice and in an in vitro model of antigeninduced demyelination. Global gene expression analysis using cDNA microarrays has proven to be a sensitive method to gain insight into molecular pathways mediating multiple sclerosis (MS) activity. Peripheral blood mononuclear cells (PBMC) gene expression can be used as a fingerprint of end- organ cerebral neurological disease. PBMC gene expression patterns in MS patients contain information about a remote-target disease process that may by useful for diagnosis and tailoring of therapeutic strategies. MS patients exhibited decreased PPAR-γ levels in PBMC compared with controls, but CSF levels of PPARγ were pronouncedly elevated in MS patients. Aiming to identify a possible alteration, the present study assessed the levels of PPARγ in the PBMC of new MS patients same as CSF report. METHODS: Blood samples were taken and PBMC were isolated by Ficoll Hipaque separation. Then RNA and c DNA prepared and with real time PCR, PPAR measured. RESULTS: We report a pronounced elevation in the PBMC levels of PPARγ in new MS patients (n=10) compared to non-inflammatory controls (n=13) with p<0.05. CONCLUSION: Corroborating with prior experimental findings, these results may contribute to our understanding about the role of PPARγ in different stages of MS. 162 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 240 A descriptive study of Multiple Sclerosis in Isfahan Mahdi Barzegar1,2, Omid Mirmosayyeb1,2,Zahra Heidari3, Vahid Shaygannejad1,2 1-Department of Neurology, School of Medicine, Isfahan University of Medical Sciences, Isfahan, Iran 2-Isfahan Neurosciences Research Center, Isfahan University of Medical Sciences, Isfahan, Iran 3-Department of Epidemiology and Statistics, School of Health, Isfahan University of Medical Sciences, Isfahan, Iran BACKGROUND: Multiple sclerosis (MS) is a demyelinating autoimmune disease of the CNS, and is the leading cause of disability in middle-aged people. The epidemiology of MS has been extensively studied and some of them have shown the fluctuating demographic pattern of MS. In other hand, prevalence of MS in Isfahan is so high. Therefore, we performed this study in order to evaluate these changes with a large number of patients. METHODS: This cross-sectional study was conducted during two years (2013-2014) in MS clinic of Kashani Hospital in Isfahan. Demographic and clinical records of 1473 definite MS patients were reviewed. Results were presented as mean±error of mean (SEM) for quantitative variables and were summarized by number (percent) for qualitative variables. Independent t-test and Analysis of variance (ANOVA) was used for comparing the EDSS score among studied groups. RESULTS: The mean age of patients was 35.06±0.25. 70.7% of them were married and the mean of EDSS was 2.07±.03. 70.1% of patients were educated but 38.0% of them were employed. Among married women, 64.8% had childbirth that 55.1% of them were caesarian. Prevalence of past viral infections in patients was 35.7% (73.3% of them were chicken pox). 79.1% of patients had psychological stress and the most prevalent stress was family issues (36.7%). 7.4% of patients were smoking. least patients diet was fish. CONCLUSION: Previous demographic pattern in another studies proved in our investigation. As same as the other diseases, prevention is better than cure. Therefore, more descriptive studies need to determine them. 163 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 241 Evaluation of serum auto antibodies in multiple sclerosis patients, a case control study in Shiraz (2013 to 2014) Sadegh Izadi1, Saeede Khoshniat2 1-Clinical neurology Research Center, Shiraz University of Medical Sciences, Shiraz Iran 2-Medical student, Shiraz University of Medical Sciences, Shiraz Iran BACKGROUND: Multiple sclerosis (MS) is an inflammatory disease in which the insulating covers of nerve cells in the brain and spinal cord are damaged. The cause of MS is unknown, however, it is believed to occur as a result of some combination of environmental factors such as infectious agents and genetics. Additionally MS is believed to be an immune-mediated disorder that develops from an interaction of the individual's genetics and as yet unidentified environmental causes. The prevalence of autoantibodies in multiple sclerosis (MS) patients and their clinical associations differ between various studies, some studies shows increase of some auto antibodies level such as: APLA (anti-phospholipid), ANA (antinuclear antibodies), ANCA (anti-neutrophilic antibodies), anti-β2GPI (anti-beta-2-glycoprotein I), anti-ds-DNA (anti-double strand DNA) and ACLA (anti-cardiolipin antibodies). METHODS: This cross case-control study investigated APLA, ANA, ACLA, p-ANCA, c-ANCA, anti-β2GPI and anti-dsDNA in 54 patients with MS and clinically isolated syndrome (CIS). The results were compared with 25 healthy individuals as control group. RESULTS: Among 54 patients with relapsing- remitting MS (RRMS) or CIS, abnormal tests were found in 15 patients (27.9%); 6 (11.1%) had positive antinuclear antibodies, 3 (5.6%) had positive ACLA, 47 (11.2%). None of the patients had any clinical manifestations other than MS symptoms. In patients group ds-DNA was positive in 5.6% of cases that had no significant difference with control group (0%) (P=0.7), but APLA and B2GP were negative in all patients and control group. The females had more positive auto antibodies in comparison to males, but they were not significant. CONCLUSION: The results of this study showed that significant number of patients with multiple sclerosis have positive serum auto antibodies tests without clinical expression of any other autoimmune disease. 164 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 242 Effect of Fingolimod treatment on the number of LAG-3 expressing T regulatory cells in Multiple Sclerosis patients Nahid Sedaghat1,2,Sayyed Hamid Zarkesh-Esfahani3, Fereshteh Alsahebfosoul1,2, Masoud Etemadifar2,4, Vajihe Ostadi1, Fariborz Kianpoor1, Mojtaba Akbari4 1-Department of Immunology, School of Medicine, Isfahan University of Medical Sciences, Isfahan, Iran 2-Isfahan Multiple Sclerosis (MS) and Neuroimmunology Researches Center, Isfahan, Iran 2-Department of Biology, Faculty of Sciences, University of Isfahan, Isfahan, Iran 3-Department of Neurology, School of Medicine, Isfahan University of Medical Sciences, Isfahan, Iran & Isfahan Multiple Sclerosis (MS) and Neuroimmunology Researches Center, Isfahan, Iran 4-Shiraz University of Medical Sciences, Shiraz, Iran BACKGROUND: Multiple sclerosis (MS) is a chronic, inflammatory and autoimmune disease of the central nervous system. The disease is considered as a T cell mediated with an abnormal immune response. It is the result of breakdown in the mechanisms that control self-reactive lymphocyte and immune tolerance. Regulatory T lymphocytes play a crucial role in the control of autoimmune disorders. It is generally believed that CD4+Foxp3+ regulatory T cells (Treg) are functionally impaired in MS patients and restoring their function will be beneficial for MS patients. PURPOSE: The aim of this study was to evaluate the effect of Fingolimod on the number of CD4+Foxp3+ T regulatory cells expressing LAG-3 (an inhibitory marker). METHODS: Total number of T regulatory cells CD4+Foxp3+ expressing LAG-3 were measured in peripheral blood samples of 20 MS patients before and after Fingolimod treatment using three color flow cytometry (BD FACSCalibuar). Flow cytometry data were analyzed using CellQuest PRO software and SPSS program. RESULTS: There was an increase (p<0.005) in the total number of CD4+Foxp3+LAG3+ Treg after 1 month of fingolimod therapy when compared with baseline. CONCLUSION: In conclusion, fingolimod therapy enhances Treg numbers expressing LAG-3 which may contribute to the improvement of the disease. These findings could be a new aspect in therapeutic target for MS. 165 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 243 High Dose vitamin D on Interleukin-10 in Multiple Sclerosis Fereshteh Ashtari, Nafiseh toghianifar, Sayyed hamid Zarkesh-Esfahani, Marjan Mansourian Isfahan University of Medical Sciences, Isfahan, Iran BACKGROUND: Multiple sclerosis (MS) is a chronic demyelinating disease of the central nervous system. Vitamin D has been related to prevention of MS development and modulating its course. This study compared the effects of high dose vitamin D on interleukin-10 levels on MS patients in a double blind randomized clinical trial. METHODS: 94 patients with relapsing remitting multiple sclerosis (RRMS) were randomized to treatment vs placebo groups. Both groups received conventional MS treatments. The intervention group received 50,000 IU vitamin D every five days for 3 months. Demographic characteristics, EDSS score, disease duration, number of attacks and medications were recorded. Serum levels of Vitamin D and interleukin 10 (IL-10) were measured and compared at baseline and after 3 months. RESULTS: Serum levels of IL-10 were 41.66±85.16pg/ml and 21.08±35.62 in the intervention and placebo group at baseline, respectively (p=0.161). After 3 months, IL-10 levels were 71.07±16.65 and 32.23±38.49 in the intervention and placebo group, respectively (p=0.158). In linear regression model, interleukin levels showed significant difference in intervention and placebo groups (p=0.022, β=0.032). CONCLUSION: IL-10 levels are reduced significantly in RRMS patients after taking high dose vitamin D for 3 months. High dose vitamin D might be useful in reducing inflammatory state in RRMS patients. 166 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 EPILEPSY 167 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 244 Frequency of common etiologies of late onset seizure in elderly patients with seizure diagnosis in department of neurology of Sina hospital in Hamadan over a 10-year period Mehrdokht Mazdeh, Abbas Khosravi Farshchian Hospital of Hamadan, Hamadan University of Medical Sciences, Hamadan, Iran BACKGROUND: After cerebrovascular disorders and dementias, epileptic seizures constitute the third most frequent neurologic problem encountered in the elderly. Epilepsy can affect any one at any age. The incidences of seizures and epilepsy in the population show a peak after 65 years of age. Due to the lack of reported clinical aspects of seizure and epilepsy in the older patients in our region in Iran, this study was conducted to describe etiology, the clinical manifestation, seizure types and subtypes. METHODS: A retrospective study was performed on all elderly patients with final seizure diagnosis, referred to the Sina hospital in the city of Hamadan, Iran over a 10-year period. All medical records and previous medical histories were reviewed. A total of 270 patients aged 65 years or above with new onset seizure were included. RESULTS: In this study, a total of 270 patients with late-onset seizure were studied. Cerebrovascular accident was found to be the most common cause of late-onset seizure in elderly (41.9%). In 108 patients (40%) etiology was unknown, 18 patients (6.6%) had brain tumors, 10 patients (3.7%) had history of head trauma, 10 patients (3.7%) had degenerative disorders and 15 patients (5.4%) had rare causes like withdrawal, brain infection, HTN crisis and drug. Most seizure type was generalized seizure (76.7%). The most frequent clinical symptom of seizure was generalized tonic–clonic seizures. CONCLUSION: the most common cause of late-onset seizure in elderly was cerebrovascular accident, most seizure type was generalized seizure and the most frequent clinical symptom of seizure was generalized tonic–clonic seizures. Since seizures were associated with a central nervous system disease and the elderly are the most rapidly growing segment of the population in our country careful investigation is necessary. Referring older patients to a specialist or a specialist epilepsy center allows speedy assessment, appropriate investigation and treatment, and less likely to miss the diagnosis. We also recommend better control of risk factors for cerebrovascular diseases in our country. 168 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 245 Antiepileptic Drug Induced Hypersensitivity and the HLA Complex Hossein Ali Ebrahimi, Ali Nasiri Neurology Research Center, Kerman University of Medical Sciences, Kerman, Iran Epilepsy is considered to be among the most prevalent neurological disorders and one of most important health issues. The first choice of treatment is antiepileptic drugs (AEPs). One of the problems in AEPs treatment is adverse effects. Two type adverse effects are seen, at first cutaneous eruption in first months after initiation of drug, and the second is late adverse effects. In individuals taking AEDs, the overall maculopapular eruption incidence rate is 2.8%; incidence rates of rash caused by PHT, LG, and CBZ are higher at 5.9%, 4.7%, and 3.7%, respectively. In-depth genetics studies on AEDs-induced adverse reactions suggest that incidence rates of AEDs-induced Stevens-Johnson Syndrome/Toxic Epidermal Necrolysis (SJS/TEN), vary among ethnic groups and that the associations with relevant loci are different. Although the incidence rates of SJS and TEN are low, mortality rates nevertheless reach 10– 50%. Thus, avoiding SJS/TEN is one of the major challenges during AEDs treatment. Recent studies have indicated that Sever Cutaneous Reactions (SCRs) such as SJS and TEN induced by AEDs are associated with the HLA-B*1502 allele. This HLA type in Europe is rare, but in southeastern of Asia is common. In individuals of Northern European ancestry, CBZ-SJS/TEN incidence is not associated with HLA-B*1502, but it is associated with HLA-A*3101. In Japan, HLA-B*5901 and HLA-B*5801 loci are risk factors for CBZSJS/TEN. In Iran there is not study for this issue. We decided to done HLA typing in SJS/TEN patients due to lamotrigine. We will discuss the clinical utility of HLA typing as predictive or diagnostic testing for drug-induced hypersensitivity and results of study. 169 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 246 Infantile Masturbation and Paroxysmal Disorders: Report of Three Rare Cases from Northern Iran and Literature Review Mohammadreza Salehi Omran, Mohammad Ghofrani, Ali Ghabeli Juibary Student Research Committee, Faculty of Medicine, Mashhad University of Medical Sciences, Mashhad, Iran BACKGROUND: A recurrent paroxysmal presentation in children leads to different diagnoses that among them neurologic and cardiac etiologies are in above the list. Infantile masturbation is not a well known entity and can not be differentiated easily from other disorders. Aim of this study is elucidating and differentiating this condition from epileptic seizures. CASE PRESENTATION: We report 3 cases of 10 to 30 month old girls of infantile masturbation that their symptoms initiated at 2, 3 and 8-month-old. These present with contraction and extension of lower extremities, scissoring of legs, perspiration, changing face color. In 2 cases body rocking and legs rubbing initiated then after. DISCUSSION: Masturbation is one of the paroxysmal non epileptic conditions of early infancy and is in differential diagnosis of epileptic seizures. With detailed history taking and close observation we can prevent useless studies and treatments. 170 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 247 Sturge-Weber syndrome: Case Series and Literature Review Mohammadreza Salehi Omran, Ali Ghabeli Juibary Student Research Committee, Faculty of Medicine, Mashhad University of Medical Sciences, Mashhad, Iran PURPOSE: Sturge-Weber syndrome (SWS) is a rare congenital sporadic disease with neuro-ocular, cutaneous and vascular findings. Clinically, the full-blown condition consists of a facial port-wine stain (PWS) involving the V1 facial trigeminal skin area, alone or in combination with V2 and V3 PWS, seizures and ocular abnormalities (glaucoma and choroidal angioma). Radiologically, a leptomeningeal (pial) capillary and venous malformation, mostly located in the parieto-occipital area, cerebral atrophy and calcifications are demonstrated. METHODS: A retrospective review of the records of patients diagnosed of SWS (facial nevus flammeus at least over the first branch of the trigeminal nerve and ipsilateral leptomeningeal angioma) was performed. Eight patients with Sturge-Weber studied. RESULTS: The nevus flammeus was unilateral in 7 patients and bilateral in 1 patient and in one patient on the same side of the leg. All of these patients had cerebral lesions. Seizures, most of which were focal, were present in 6 patients (75%) usually contralateral to the nevus flammeus. Seizure presentation coincided with febrile episodes in none of these patients. Total seizure control was obtained in all patients. CONCLUSION: Early evaluation of newborns with nevus flammeus affecting the first branch of the trigeminal nerve must be done, including an MR with contrast and an ophthalmological exam. 171 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 248 Effects of Teucrium polium Extract on the Seizure Induced by Picrotoxin in Mice Elahe Fereidouni1, Samira Fatahi2, Mojgan Safaee2 1-Department of Physiology, Kermanshah University of Medical Sciences, Kermanshah, Iran 2-Department of Nursery, Kermanshah University of Medical Sciences, Kermanshah, Iran BACKGROUND: Neurological effects of Teucrium polium have been recognized for many years. In this study, the anticonvulsant activity of methanolic extract of the plant was investigated in mice. Picrotoxin with doses of 6 and 12.5 mg/kg were used for induction of seizures. The effects of different doses of methanolic extract of the plant on the variation of beginning time of seizures, the incidence of tonic and clonic seizures and mortality rate were determined. METHODS: The beginning time of tonic seizures induced by picrotoxin (6 & 12.5 mg/kg IP) were delayed significantly in group which received extract (50 mg/kg IP) 20 min before picrotoxin administration. RESULTS: Latency of beginning time of tonic seizures in mice which receive picrotoxin 6 mg/kg were increased significantly from 10.58 min to 15 min (P<0.05) and in case of 12 mg/kg of picrotoxin from 5.87 to 10.82 min (P<0.01). The incidence of clonic seizures and mortality rate were decrease in this group of animals (P<0.05, P<0.01). CONCLUSION: The results indicated that Teucrium polium extract may be effective on generalized tonic, clonic and tonic- clonic seizures and the dose of 50 mg/kg was enough to produce effective concentration for anticonvulsive activity of the extract in mice. 172 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 249 The role of High-Frequency Oscillations in epileptic surgery Nasim Tabrizi Department of Neurology, Mazandaran University of Medical Sciences, Sari, Iran Detection of high frequency oscillation (HFO) is a new clinical diagnostic method in epilepsy and epilepsy surgery. HFOs seem not only a spatial marker of the focus of epileptogenicity, but also a temporal marker for epileptic intensity. They also could be useful to evaluate treatment effect. Obviously, identification of epileptogenic zone is the main goal of presurgical evaluation in epileptic patients. Recent studies have shown that identification of HFOs appears capable of improving presurgical diagnosis and surgical outcome by introducing a new area called HFO zone. Removal of HFO zone seems to predict good outcome, even better than removal of the ictal onset zone. Specificity of HFOs has been proved in both temporal and extratemporal epilepsy. Several studies with microelectrodes conclude that fast ripples are most specific for the epileptogenic zone, but in clinical studies with macroelectrodes it is useful to include both ripples and fast ripples in the evaluation of the potential epileptogenic region. Although HFOs have been seen on scalp electroencephalography (EEG), the best way to record them is intracranial EEG which limits their usage. But due to promising results, it may be the time to include HFO information in the clinical workup of epilepsy surgery patients to improve surgical outcome and to reduce the need for traditional long-term recordings. 173 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 250 New conceptions about drug-resistant epilepsy Majid Ghaffarpour Iranian Center of Neurological Research, Imam Khomeini Hospital, Tehran, Iran Epilepsy is a common neurological disorder, affecting approximately 1 to 2 of population. A communitybased study estimated that up to 22.5% of epilepsies are drug resistant, which have increased premature death, injuries, psychological dysfunction and a reduced quality of life. According to global consensus of international league against epilepsy (ILAE), drug resistant epilepsy is defined as a failure of adequate trials of two (or more) tolerated, appropriately chosen and dosed antiepileptic drug regimens (whether administered as monotherapies or in combination) to achieve freedom from seizures. This definition was based on the observation that if complete seizure control is not achieved with two appropriate drugs, the likelihood of success with subsequent regimens is much reduced. Although drug resistance may remit over time, at a rate of 4% per year among adults and higher rate in children, seizure relapse is common. It is important to rule out pseudoresistancy and to understand how seizures become drug resistance. The mechanisms of drug resistance are variable and multifactorial. Major hypotheses include over-expression of drug transporter proteins (failure of drug to reach targets) such as p-glycoprotein and multidrug resistance proteins (MRP1-7), alteration in drug targets, drug missing the real target and inherent disease severity. Pharmacoresistancy become also apparent in patients with status epilepticus when seizure continues for more than 30 minutes, which is explained by intensified over expression of NMDA receptors and internalization of the GABAA and AMPA-receptors. In This lecture we will review further details about pathogenesis of drug resistance and reasons of pseudoresistancy, treatment and outcomes of RSE and S-RSE. 174 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 251 Neonatal Capsaicin effects on PTZ-induced convulsions in 20-day-old Rats Elnaz Khorasanian, Ali Moghimi, Masoud Fereidoni Research Center For Neuroscience & Behavior, Department of Biology, Faculty of Science, Ferdowsi University of Mashhad, Iran BACKGROUND: During postnatal development, sensory experiences play critical roles in the organization and plastic changes of cortical connections. Degeneration of peripheral sensory neuron terminals lead to functional alterations of substrates at cortical levels. Epilepsy is a neurological disorder characterized by spontaneous, recurrent seizures. There is a little knowledge about neonatal event impact on epilepsy etiology. Capsaicin, the hot chemical in chilies, can destroy polymodal nociceptive primary afferent neurons and has epileptic effect when injected i.c.v. PURPOSE: Here, we assesse C-fiber elimination effect which induced by neonatal capsaicin intraperitoneally injection (50mg/kg, i.p) on latency and duration of Seizures induced by pentylenetetrazole (PTZ) in 20th after birth. METHODS: Two –day-old pups were divided into experimental (N=7) and sham groups (N=7) and (i.p) treated with Capsaicin or Capsaicin vehicle (tween 80, ethanol and salin, 10:10:80), respectively. C-fiber destructions were confirmed by Ammonium hydrochloride (wipe test) on the day 14th. Seizures were induced with PTZ (50mg/kg. i.p). On the day 20 after birth and the latency of unset and duration of generalized epileptiform convulsion was recorded. RESULTS: Capsaicin -treated group shows significant difference in unset latency of behavioral convulsions (P<0.05) and duration of seizures induced by PTZ (P<0.05) in comparison with sham group. CONCLUSION: It may be that C-fibers are involving in the inhibitory system development in neonate rat during the critical period of brain development, so C-fibers destruction can lead to elimination or diminishing the brain inhibitory system specially GABAergic one, so it potentiate the effect of PTZ induce seizure. 175 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 252 Effect of hydroalcoholic extract of cannabis sativa l. flower tops chronic administration on severity and duration of pentylenetetrazole induced convulsions in neonate rat Samane Afroozi, Ali Moghimi, Masoud Fereidoni Research Center For Neuroscience & Behavior, Department of Biology, Faculty of Science, Ferdowsi University of Mashhad, Iran BACKGROUND: Epilepsy is a serious neurological disorder, which is outcome of disturbing the natural balance between excitation and inhibition in the central nervous system and caused by intermitted and abnormal electrical discharges in the brain neurons. Considering the prevalence of epilepsy and the failure of available treatments for many epileptic patients, finding more effective drugs in the treatment of epilepsy seems necessary. Cannabis Sativa L. is an ancient and medicinal plant that has been used for treatment of insomnia, inappetence, and nausea in traditional medicine. Phytocannabinoids in Cannabis Sativa L. have different pharmacological targets on the nervous system. PURPOSE: The aim of this study was to investigate the effect of hydroalcoholic extract of Cannabis Sativa L. flowertops on duration time of epileptic seizure stages induced by pentylenetetrazol in neonate rats. METHODS: Neonate wistar rats (4 days old) were divided into four groups, including a group receiving interaperitoneal (i.p) solvent and three experimental groups (receiving the hydroalcoholic extract in 3 doses 1,10,50 mg/kg/i.p) started from 4th day of birth to 9th day of birth. In 14 day after birthday, pentylenetetrazol (50 mg/kg/i.p) was injected and convulsive behaviors were recorded by a camera during 60 minutes and different phases of seizures and duration of convulsions were scored. RESULTS: The extract injection in dose of 50 mg/kg/i.p showed significant reduction of duration time in tonic-clonic seizures compared with the group receiving solvent (p<0.05). CONCLUSION: Our study indicated that the hydroalcoholic extract of Cannabis Sativa L. has an appropriate anticonvulsant effect, maybe by activation GABAergic system as other researches claimed it is hypnotic effects, our results may due to the same mechanisms, which needs more study to clarify. 176 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 253 Tamoxifen mimics the effects of endogenous ovarian hormones on repeated seizures induced by pentylenetetrazole in rats Somaieh Mansouri, Maryam Ataei, Mahmood Hosseini, Alireza Ebrahimzade Bideskan Mashhad University of Medical Science, Mashhad, Iran PURPOSE: In the present study, the effects of tamoxifen on pentylenetetrazole (PTZ)-induced repeated seizures and hippocampal neuronal damage in ovariectomized rats were investigated. METHODS: Thirty seven virgin female Wistar rats were divided to: (1) control, (2) sham-PTZ, (3) shamPTZ-tamoxifen (sham-PTZ-T), (4) Ovariectomized -PTZ (OVX-PTZ) and (5) OVX-PTZ-tamoxifen (OVXPTZ-T) groups. The animals of groups 3 and 5 were injected by tamoxifen (10 mg/kg) on 7 consecutive days. After 7 days of tamoxifen injection, they also were then injected by tamoxifen 30 min prior each PTZ injection. PTZ (40 mg/kg) was injected on 6 consecutive days and the animal behaviors were observed for 60 min. The histological methods were then used to determine dark neurons in hippocampus. RESULTS: A significant decrease in the seizure score was seen in OVX-PTZ group compared to Sham-PTZ. The animals of OVX-PTZ-T group had a significant higher seizure score compared to OVX-PTZ group. The dark neurons in DG of OVX group were lower than sham group (p<0.01). The numbers of dark neurons in CA1 area of OVX-PTZ-T group was higher than OVX-PTZ group (p<0.05) compared to control, the numbers of dark neurons in CA3 area showed a significant increase in Sham-PTZ and OVX-PTZ group (p<0.05 and p<0.01 respectively). Dark neurons in OVX-PTZ-T group were higher than OVX-PTZ group (p<0.05). CONCLUSION: It is concluded that pretreatment of the ovariectomized rats by tamoxifen increased PTZinduced seizure score and dark neurons. It might be suggested that tamoxifen has agonistic effects for estrogen receptors to change the seizure severity. 177 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 254 Epilepsy surgery as a treatment option for patients with Lennox-Gastaut syndrome Mahmoud Abedini, Nasim Tabrizi, Ashraf Zarvani, Narges Karimi Department of Neurology, Mazandaran University of Medical Sciences, Sari, Iran Lennox-Gastaut syndrome (LGS) is a severe epileptic encephalopathy of childhood onset characterized by mixed seizure types, cognitive dysfunction, and electroencephalogram (EEG) pattern of slow spike-waves. Seizure types typically include tonic, atonic, and atypical absence, but may include other types, such as tonic–clonic, myoclonic, or partial seizures. Because patients with LGS experience a range of different seizure types, the condition is extremely difficult to treat and seizures in LGS are usually not fully controlled. LGS is often the result of bihemispheric pathology, but seizures may be caused by focal abnormalities of the brain, such as tumors, cortical tubers, and cerebral malformations. Up to 25% of patients with LGS have persistent focal abnormalities or asymmetry of slow spike-wave discharges on EEG. Patients with LGS who are refractory to antiepileptic medications may be considered candidates for surgical intervention. Several presurgical investigations are required including video-EEG monitoring, magnetic resonance imaging (MRI) and age appropriate neuropsychological or developmental assessment. Also some supportive tests may be utilized in the surgical evaluation of patients including those that aid in localizing the region for resection such as PET, SPECT and MEG and those that are useful to delineate eloquent cortex to minimize neurologic deficits related to surgery (e.g., Wada, functional MRI and electrocorticography). The major strategies for surgical treatment in these children are cortical resection and corpus callosotomy (CC). Resection may be a curative surgery, whereas CC is considered a palliative surgery, usually considered when resective surgery is not suitable. Recent studies have shown that resective surgery in patients with LGS with dominance of EEG discharges in one hemisphere can be successful in terms of seizure reduction in majority of patients. Results of studies on CC in patients with LGS have also shown that this surgery can reduce seizure frequency in a significant way. But due to complications of surgery, few trials of radiosurgical techniques have been reported with similar efficacy but with fewer postsurgical side effects. Vagus nerve stimulation (VNS) is also considered a palliative surgery option for patients lacking a resectable seizure focus. CC and VNS often result in similar rates of seizures reduction; however, CC may be more effective for atonic seizures and VNS is associated with milder complications. With major advances in imaging technology and surgical techniques and improving safety, continuing studies are warranted for surgery in the treatment of LGS. 178 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 255 The effect of Vitamin E on the seizure frequency, EEG findings and biochemical parameters of epileptic patients treating with Carbamazepin, Sodium valproate and Levetiracetam Zare M, Gholami F, Mahvary J, Agha Ghazwyni MR, Najafi MR, Alavi AM Isfahan University of Medical Science, Department of Neurology, Isfahan Neuroscience Research Center, Isfahan, Iran BACKGROUND: Epilepsy is one of the common neurological disorders characterized by seizures caused by electrical brain disorders with great destructive impact on people's social and economic life. Vitamin E is a natural antioxidant without any significant complication which is easily used. PURPOSE: This study aimed to evaluate the effect of this vitamin on increasing the effects of antiepileptic drugs. METHODS: This double-blind, placebo-controlled clinical trial have done on 66 patients with epilepsy treated with antiepileptic drugs referred to Kashani hospital and private clinics in Isfahan. Non-random simple sampling 33 patients were allocated to intervention and control groups. The intervention group was given daily supplements of 400 IU vitamin E and the control group gave similar pills of vitamin E as placebo. Patients were examined monthly about the seizure frequency and EEG and blood biochemical markers at the end of sixth months. Data were analyzed by SPSS software using Chi square test and T-test. RESULTS: The mean of total antioxidant in cases before treatment was 6.2±2 and significantly increased to 7.7±2.1 after treatment (P-value=0.001), but in controls was increased of 7.3±1.9 to 7.4±2.1 (Pvalue=0.91). The mean of catalase in cases was 14.3±5.1 and significantly increased to 17.5±5.4 after treatment (P-value<0.0001), in controls was 17.5±5.2 and increased to 17.4±6 (P-value=0.44). The mean of glutathione in cases after treatment was significantly increased compare to before treatment (13.6±6.1 to 18.5±8.2, P-value<0.0001), in controls (16.4±5.7 to 16.3±5.4 respectively, P-value=0.88). Malondialdehyde decreased but was not statistically significant in case (P-values = 0.1), but in control don’t decreased (p-value=0.53). The mean number of seizure in cases after treatment was significantly decreased compare to before (2.25±0.62 to 1.34±0.83, P-value<0.0001), but in controls was similar (2.36±1.1 to 2.57±1.2, P-value<0.0001). Changes in the positive EEG findings in cases observed more than control group (50% versus 12.1% respectively, P-value=0.001). CONCLUSION: Our results showed that vitamin E in addition to antiepileptic drugs improved antioxidant parameters and seizure frequency and positive EEG finding in compare to placebo, but no significant effect on reduced oxidative stress (respect to Malondialdehyde enzyme). 179 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 256 Association of Family History of Epilepsy with Earlier Age onset of juvenile myoclonic epilepsy Mohammad Reza Najafi1,2, Mohammad Amin Najafi2,3, Ali Safaei2,3 1-Department of Neurology, Isfahan University of Medical Sciences, Isfahan, Iran 2- Isfahan Neurosciences Research Centre (INRC), Isfahan University of Medical Sciences, Isfahan, Iran 3-Isfahan University of Medical Sciences, Faculty of Medicine, Isfahan, Iran BACKGROUND: Juvenile myoclonic epilepsy (JME) is assumed to be the most frequent subtype of idiopathic generalized epilepsies (IGE). PURPOSE: The aim of this study was to determine the prevalence of JME and comparison of patients' demographics as well as timeline of the disease between positive family history epileptic patients (PFHE) and negative family history epileptic patients (NFHE) among sample of Iranian epileptic patients. METHODS: 1915 definite epileptic patients (873 females and 1042 males) were evaluated in this study. JME was diagnosed by its specific clinical and EEG criteria. Patients were divided into two groups: PFHE and NFHE patients and the data were compared between these two groups. RESULTS: JME was responsible for 10% (194 patients) of all types of epilepsies. 53% of our JME patients were female and 47% were male. 40% of JME patients had family history of epilepsy. No significant differences between PFHE and NFHE groups in terms of gender (p-value>0.05). Age of epilepsy onset was significantly earlier in PFHE patients (15 vs. 22, P-value<0.001). Occurrence of JME before 18 years old among PFHE patients was significantly higher (OR=2.356, P-value=0.007). CONCLUSION: Our study demonstrated that a family history of epilepsy is associated with an earlier age of onset in patients with juvenile myoclonic epilepsy. 180 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 257 Role of Family history in diagnosis of epilepsy in Iranian patients with epilepsy Mohammad Reza Najafi1,4, Mohammad Amin Najafi2,4, Ali Shahsavari2,4, Ramin Shayan Moghadam2, Farzaneh Najafi3, Rokhsareh Meamar4, Ali safaei2,4, Ali Kamal2, Amirsalar Nurbakhsh2, shayan mostafaei5 1-Professor of Neurology, Department of Neurology, Isfahan University of Medical Sciences, Isfahan, Iran 2-Medical student, Isfahan University of Medical Sciences, Faculty of Medicine, Isfahan, Iran 3-Postdoctoral researcher, Cold Spring Harbor Laboratory, Cold Spring Harbor, USA 4-Isfahan Neurosciences Research Centre (INRC), affiliated to Isfahan University of Medical Sciences, Isfahan, Iran 5-Divisions of Biostatistics, Department of Epidemiology and Biostatistics, School of public Health, Isfahan University of Medical Sciences, Isfahan, Iran BACKGROUND: Role of family history on epilepsy classifications, etiology and patients’ demographics still remains unclear.

METHODS: 1915 definite patients with epilepsy (873 females and 1042 males) enrolled in this retrospective study. Positive family history and negative family history patients were identified and compared in terms of gender, age, age of epilepsy onset, classification (generalized, partial and unknown) and etiology (Idiopathic, symptomatic and cryptogenic) of epilepsy. RESULTS: 33.4% of patients (n=1915) had a history of epilepsy in their family. 21.6% had a first-degree relative with epilepsy, and 11.8% had a second-degree epileptic relative. The mean age of epilepsy onset was 21. Positive family history patients showed an earlier age of onset (16 vs. 24; independent-T test, p<0.001). Idiopathic, symptomatic and cryptogenic epilepsy were significantly different between the two groups (chi-square test, p<0.001). Generalized and unknown types of epilepsy were also significantly different between positive and negative family history patients (chi-square test, p<0.05). CONCLUSION: Family history has a significant impact on the classification, etiology and timeline of epilepsy. These findings may be affected by the high incidence of consanguineous marriage seen in our population. 181 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 258 Evaluation of brain MRI findings in Iranian patients with seizure and normal neurologic examination Omid Hesami1, Mostafa Asadollahi1, Mahyar Noorbakhsh2 1-Departmentof neurology, Imam Hossein Hospital, Shahid Beheshti University of Medical Sciences, Tehran, Iran 2-Neurologist, Tehran, Iran BACKGROUND: This study was set up to determine the rate of abnormal brain MRI findings in Iranian patients with seizure who have a normal neurologic examination. METHODS: This is a cross-sectional, retrospective study. Data of 148 patients with definite seizure diagnosis and available brain MRI report who were admitted to Imam Hossein hospital during 1387-1390 were recruited and entered in study. All the patients had been imaged using MRI sequences of T1, T2, FLAIR and epilepsy protocol on 1.5 tesla system. Frequency of abnormal MRI was determined in relation to patients’ age, gender, type of seizure and EEG findings. RESULTS: 68 patients were female (46 %) and 80 ones were male (54%). Mean age of patients was 43.6±22.7 years. 56 patients had pathologic finding in brain MRI (38.2%) and 92 ones had normal MRI (61.8%). Mean age of the patients with MRI abnormality was compared to those without. The values were 49.7±21.2 and 39.9±22.8 respectively and the difference was significant (P=0.035). 20 females (29.8%) and 36 males (45.5%) had abnormal MRI and the difference between two genders was not significant (P=0.105). The frequency of abnormal brain MRI was not significantly different among various seizure types (P= 0.336). In total, EEG was normal in 36 patients (24.5%) and abnormal in 112 ones (75.5%). In patients with abnormal EEG, 45 ones (40.3%) and in those with normal EEG, 11 ones (32%) had abnormal MRI and the difference was not significant (P=0.460). CONCLUSION: Older patients were more likely to have abnormal MRI than younger ones and therefore the older should be imaged more urgently. However, Patients’ gender and seizure type were not determinant factors in prediction of MRI abnormality. Also a normal EEG could not implicate that brain MRI is also normal and one should not forbear brain imaging on basis of a normal EEG. 182 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 259 Descriptive review of surgery outcome in 35 cases with refractory epilepsy Jafar Mehvarihabibabadi, Houshang Moein, Reza Basiratnia, Majid Barekatain, Mohammad Zareh, Elham Rahimian, Amirali Mehvari habibabadi, Shervin Badihian Isfahan Neurosciences Research Center, Isfahan University of Medical Sciences, Isfahan, Iran & Kashani Comprehensive Epilepsy Center, Isfahan University of Medical Sciences, Isfahan, Iran BACKGROUND: Both medical and surgical treatments have been suggested for patients with tumor associated epilepsy. However, in recent studies, surgical treatment has been considered because of the reducing rate of seizure recurrence after surgery. The aim of this study was to investigate surgery outcome in patients with refractory epilepsy. METHODS: The medical records of 35 individuals (18 female and 17 male, age: 8-45) with tumor associated epilepsy were reviewed. All the patients were cases of refractory epilepsy that underwent tumor resection surgery and were followed for 2 to 4 years in Kashani comprehensive epilepsy center, Isfahan, Iran. RESULTS: Most patients presented with 30 seizures or more per month (57.6) which consisted of one or two types of seizure at time of admission (57.1% and 37.1% respectively). They were on one to three anticonvulsant drugs in most cases (75.8%). Carbamazepine, Sodium Valproate, and Phenobarbital were mostly used. After required evaluations, almost all the patients underwent lesionectomy by the same neurosurgeon which resulted in paresis and language deficit in 8.6% and 2.9% of cases respectively. Ganglioglioma was reported in 62.9% of cases, Astrocytoma in 27.6%, and DNET in the rest. After two to four years follow-up, 65.6% of patients were seizure free. In terms of Engels class, 79% of cases were classified as class I, 8.8% class II, 2.9% class III, and 5.9% class IV. Anticonvulsant drugs were discontinued in 18.8% of patients successfully without any recurrent seizure and 53.9% of patients experienced less frequent seizures postoperatively with lower dosage of antiepileptic drugs or fewer numbers of them. The rest remained on the same amount of medication for their seizure control and 5.9% experienced no change or even more seizures. CONCLUSION: A variety of medical and surgical treatments has been suggested for patients with tumor associated epilepsy. Despite studies have addressed the issue, the best choice of therapy has remained controversial yet. Our study showed a favorable outcome of surgery in patients with tumor associated epilepsy which is compatible with several previous studies. Given the considerable postoperative outcome in our patients, and long-term effects of seizures and drug use on individuals and their quality of life, earlier surgical treatment may lead to better results. It seems the optimal management of these patients requires a multidisciplinary approach including either drug treatment or surgical treatment or a combination of those. 183 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 260 Current management and surgical outcomes of intractable epilepsy in Rasmussen's encephalitis: investigation of two cases with literature review Jafar Mehvari habibabadi, Seyed Mohammad Ghodsi, Fatemeh Fadaie, Seyed Sohrab Hashemi Fesharaki, Mohammadmehran Poorsina, Marzieh Gharakhani, Masoumeh Najafi Ziarani, Elham Rahimian, Amirali Mehvari Habibabadi Isfahan Neurosciences Research Center, Isfahan University of Medical Sciences, Isfahan, Iran & Kashani Comprehensive Epilepsy Center, Isfahan University of Medical Sciences, Isfahan, Iran BACKGROUND: Rasmussen’s encephalitis (RE) is a rare but severe immune-mediated brain disorder leading to unilateral hemispheric atrophy, associated progressive neurological dysfunction with intellectual decline, and intractable seizures. The only established therapy that will cure the seizures and allow the patient to resume a satisfactory life is hemispherectomy. There is accumulating evidence that disconnective techniques are associated with a lower incidence of complications as compared to anatomical hemispherectomies. This study described two patients who were a known case of Rasmussen encephalitis and did functional hemispherectomy. CASE PRESENTATION: The first case was an 18 year old male presented with epilepsia continua and right hemiparesis. The disease has being started since he was 10 year old. Habitual seizure consisted of right side clonic jerks which at times led to secondary GTCS. Data coming from Video EEG Monitoring pointed to left fronto-parietal as a source of seizure. MRI showed left side atrophy and scar particularly on the frontotemporal region. Overall data suggested Rusmussen encephalitis. Case two was a 26 year old female presented with a history of intractable seizures since she was 23 year old. During these years she gradually developed left hemiplegia and speech problem. During 24-hour admission in EMU, she had frequent attacks of staring which are started from left paracentral with theta activity. MRI showed right temporal and frontal atrophy with a mild generalized atrophy. Clinical presentation, EEG and MRI suggest Rasmussen encephalitis. Result: For both cases, functional hemispherectomy was done and the seizures became under controlled in both cases. Case one was well up to 2 weeks after surgery but at that time, he developed meningitis and become aphasic. Since then he had no seizure but aphasia and right hemiplegia. CONCLUSION: Epilepsy surgery has played a major role in the management of RE. Hemispherectomy and its modern variants are highly effective in achieving seizure freedom and offer the only ‘cure’ for preventing disease. Surgical option should weigh the severity of deficits to be expected after hemispherectomy in relation to the severity of epilepsy and the consequences of its treatment. In such patients with affection of the non-dominant hemisphere and with handicapping epilepsy, hemispherectomy should be considered relatively early on. Our experience has suggested that patients with RE and refractory epilepsy in particular may benefit from hemispherectomy. 184 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 261 Therapeutic approaches to super-refractory status epilepticus Khosro Jamebozorgi1, Behnam Safarpour Lima2 1-Department of Neurology, Zabol University of Medical Sciences, Zabol, Iran 2-Department of Neurology, Imam Hossein Hospital, Shahid Beheshti University of Medical Sciences, Tehran, Iran Super-refractory status epilepticus is defined as status epilepticus that continues or recurs 24 h or more after the onset of anaesthetic therapy, including those cases where status epilepticus recurs on the reduction or withdrawal of anaesthesia. It is an uncommon but important clinical problem with high mortality and morbidity rates. This article reviews the treatment approaches. There are no controlled or randomizes studies, and so therapy has to be based on clinical reports and opinion. The published world literature on the following treatments was critically evaluated: anaesthetic agents, anti-epileptic drugs, magnesium infusion, pyridoxine, steroids and immunotherapy, ketogenic diet, hypothermia, emergency resective neurosurgery and multiple subpial transection, transcranial magnetic stimulation, vagal nerve stimulation, deep brain stimulation, electroconvulsive therapy, drainage of the cerebrospinal fluid and other older drug therapies. 185 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 BASIC NEUROSCIENCE & NEUROPHARMACOLOGY 186 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 262 The New Event Related to the Pharmacotherapy of Myasthenia Gravis: A Review Zahra Tolou_Ghamari Isfahan Neurosciences Research Centre, Isfahan University of Medical Sciences, Isfahan, Iran BACKGROUND: The autoimmune or hereditary neuromuscular disorder, myasthenia gravis could lead to muscle faintness and tiredness. Pharmacotherapy using acetylcholinesterase to improve muscle function and immunosuppressive drugs to reduce the autoimmune process seem to be beneficial for patients. PURPOSE: To provide a review article related to different pharmacotherapy strategy of myasthenia gravis. METHODS: Directory of Open Access Journals (DOAJ), Google Scholar, Pubmed (NLM), Library, Information Science and Technology Abstracts (LISTA, EBSCO publishing) and Web of Science with key words relevant to the topic of this review were searched. RESULTS: Suggestive management for myasthenia gravis with acetylcholine esterase inhibition is usually joined with immunosuppression. According to recent publication the disease should be categorized as antibody specificity such as 1) acethylcholine, 2) muscle-specific receptor tyrosine kinase 3), low-density lipoprotein receptor, and 4) seronegative. Also thymitis, thymoma or its atrophy and type of disease course ocular or generalized seem to be important. Related to previous published articles, azathioprine, cyclosporin, cyclophosphamide, methotrexate, mycophenolate mofetil and tacrolimus seem to be drugs of choice. Study performed in 10 patients confirmed that in 3 with ocular and 7 with generalized disease intranasal neostigmine could lead to improvement of symptoms of disease. In another study performed in 19 patients confirmed that in 84.2% concurrent prescription of intravenous immunoglobulins and antibiotic therapy might provide higher clinical efficiency. A 12 months study related to pharmacotherapy using tacrolimus with a dose of 2-6 mg daily showed muscle strength in 69 patients. CONCLUSION: At the present time the therapeutic and pharmacotherapy strategies are still indicative. They mark immunological indicators more gamely than precise myasthenic gravis symptoms. In severe exacerbations, intravenous immunoglobulin, plasmapheresis and immunoadsorption are equally effective. 187 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 263 Hazardous effect of acrylamide on development of cerebellum and protective role of vitamin C Hengameh Dortaj, Morteza Anvari, Maryam Yadegari, Mohammad Hosseini Shahid Sadoughi University of Medical Sciences, Yazd, Iran BACKGROUND: Acrylamide (ACR) according to the method of cooking foods is increasingly used and its adverse effects on multiple organ systems have been described sporadically in the literature. The purpose of this study was to evaluate the effects of ACR on development and changes in cortical layer of the cerebellum and cerebellar Purkinje cells in neonates of rat by using histological, morphometric and stereological technique. METHODS: In this study 20 adult female Wistar rats weighing 180 gr and aged two months were used. Animals were randomly divided into four groups. Female pregnant rats were orally administered 10 mg/kg ACR and/or 200 mg/kg vitamin C (vit C). To study the neonatal period, 6 infants at day 21 randomly selected and placed under deep anesthesia and transcardial perfusion. The cerebellum was taken out and fixed and cerebellum changes were evaluated by crysel violet and Hematoxylin-Eosine staining method. The cerebellar cortex layers volume and the number of Purkinje cells were investigated by Cavalieri's principle and physical dissector method. Data were analyzed by SPSS software and by ANOVA and LSD Test. RESULTS: Histological and stereological examinations revealed that the cerebellar volume was decreased in ACR and ACR+vit C group vs control (P˂0.001). While in vit C group the cerebellar volume was increased (P˂0.05). ACR in newborn decreases brain weight, thickness of cerebellum and the number of purkinje cells with P˂0.001. The extent of this reduction in the weight of the cerebellum was significant with P˂0.05. CONCLUSION: ACR exhibits a harmful effect on the development of the cerebellar cortical layers, which may be prevented by administration of vit C as an antioxidant. 188 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 264 Effect of acrylamide and vitamin C and Glycyrrhiza Glabra on hippocampal Aghdas M, Dashti M, Dortaj H, Anvari M, Yadegari M Shahid Sadoughi University of Medical Sciences, Yazd, Iran BACKGROUND: Acrylamide is a chemical compound which can produce in carbohydrate rich food during high- temperatures cooking process. The neurotoxicity of acrylamide was reported in the previous studies. The aim of the present study was to evaluate the effects of co-administration of Glycyrrhiza Glabra and Vitamin C on acrylamide-induced motor deficits and learning and memory in rats. METHODS: In this experimental study, 40 male Wistar rats of 28 days of age were divided into five groups of 8 rats including Control, Acrylamide, Acrylamide + Vitamin C, Acrylamide + Glycyrrhiza Glabra and Acrylamide +Vitamin C + Glycyrrhiza Glabra. All treatments were administered (oral) daily for two months. Thereafter, locomotor activity indices, learning and memory, antioxidant activity of blood and brain apoptotic rate were measured. RESULTS: The results showed that motor deficit were significantly improved in vitamin C + Glycyrrhiza Glabra group comparing to Acrylamide group, but treatment with vitamin C or Glycyrrhiza Glabra had no significant effect. In addition, animals that treated with the combination of vitamin C and Glycyrrhiza Glabra significantly decreased escape latency in comparison with Acrylamide group. Glycyrrhiza Glabra alone could increased time spent in target quadrant. Total antioxidant activity of serum was increased in all treated group comparing to control. Hippocampal apoptotic rate did not reveal significant changes among treated groups with control. CONCLUSION: This study showed that the co-administration of vitamin C and Glycyrrhiza Glabra can retards the locomotors dysfunction and improve learning and memory in acrylamide-treated rats. Also, the co-treatment elevates total antioxidant activity of serum in rats without change in Hippocampal apoptotic rate. 189 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 265 Effect of Boswellia serrata gum resin on anxiety behavior in young male rats following prenatal stress exposure Mohammad Hosseini-sharifabad, Razieh Kamali Ardakani Shahid Sadoughi University of Medical Sciences, Yazd, Iran BACKGROUND: Evidence indicates that stressful circumstances during gestational period could induce long-term effects on anxiety behaviors. Although there is numerous anti-anxiety drugs, finding suitable herbal drugs attracted the attention of psychopharmacologists. Boswellia serrata gum resin (Frankincense or olibanum) is an herbal extract that their anti-nociceptive and neuroprotective effects reported. Therefore, this study aimed to determine the effect of Frankincense on anxiety and corticosterone levels in prenatal stressed rat offspring. METHODS: In this experimental study, one-old male Wistar rats whose mothers were exposed to restraint stress in plastic tube from gestational day 15 to 21 divided into control and experimental (frankincense) groups. Experimental group received orally the aqueous extract of the Boswellia serrata (100 mg/kg/day for 1 month) and equivalent volume of saline administered to controls. The anxiety behaviors were assessed applying Elevated plus Maze and Territory Discrimination Test. Data were analyzed with SPSS software using student t-test. RESULTS: The basal level of corticosterone didn’t differ between two groups but the amount of corticosterone 2 h after stress exposure in experimental animals was statistically lower than controls. Data also showed that experimental rats (36.3±6.88%) compared to controls (11.9±3.61%) spend more time in open arm of Elevated plus Maze (P<0.0001). In territory discrimination test, frankincense-treated rats had less latency to enter in unknown compartment and spend more time in this compartment compared to control group. CONCLUSION: Results of this study indicated that administration of frankincense (100 mg/kg/day for 1 month) could decrease the prolongation of corticosterone secretion response and also anxiety behaviors in prenatally stressed rats. 190 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 266 The effect of peripheral kisspeptin 10 administration on serum gonadotropin and histology of ovary in experimental hypothyroid rats Raheleh Assaei1, Afshin Hasanvand2 1-Department of Physiology, School of Medicine, Lorestan University of Medical Sciences, Khorramabad, Iran 2-Student Research Committee, Lorestan University of Medical Sciences, Khorramabad, Iran BACKGROUND: Kisspeptins, a hypothalamic neuropeptide transmitter, are targets for metabolic hormones, such as thyroid hormones, which regulate reproductive function. Considering hypothyroidism, a huge metabolic disturbance, associated to hypogonadotropism, we hypothesized that defective gonadotropin secretion in hypothyroidism might affect through kisspeptins. PURPOSE: To test this hypothesis, we evaluated histology of ovary and FSH and LH responses to kisspeptin, in experimental hypothyroidism in female rat. METHODS: In this study adult female wistar rats were used. The animals were divided into 8 groups: I. control + normal saline, II. Control + kisspeptin group: rats used tap water and kisspeptin injected (50x10-8nmol, i.p) daily for 9 days. III. Hypothyroid +kisspeptin: Hypothyroid rats were injected kisspeptin (50x10-8nmol, i.p) daily for 9 days. IV. hypothyroid+ normal saline: Hypothyroid rats, were injected normal saline daily for 9 days, V: hypothyroid + kisspeptin + ovariectomized: in hypothyroid ovariectomized rats kisspeptin were injected (50x10-8nmol, i.p) daily for 9 days, VI: hypothyroid + normal saline+ ovariectomized: in hypothyroid ovariectomized rats normal saline were injected (50x108nmol, i.p) daily for 9 days, VII: Control + normal saline+ ovariectomized, In this group, normal saline was injected to euthyroid ovariectomized rats daily for 9, VIII: Control + kisspeptin + ovarectomized: In this group, kisspeptin was injected to euthyroid ovariectomized rats daily for 9 days. Hypothyroidism was induced by administration of methimazole at a concentration of 0.1 % in the drinking water for 14 days. The blood samples were collected in first day, fourth day and ninth day, 1 hour after injections. Serums LH, FSH and histopathology of ovary were determined. RESULTS: Serum LH concentration decrement in hypothyroid animals returned to normal level 1 hour after injection of kisspeptin and remain at normal level after 4 and 9 days injection. Serum LH increment in hypothyroid ovariectomized animals increased after kisspeptin injection compared to hypothyroid ovariectomized rats. The number of antral type follicles decreased in hypothyroid animals that restore to the number of antral type follicles in control group, after 9 days kisspeptin injection. CONCLUSION: Altogether, these data support that kisspeptin administration ameliorates the hypogonadotropic and ovarian histology phenotype of hypothyroidism. 191 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 267 The effect of peripheral kisspeptin 10 administration on serum estradiol and progestrone and estrous cycle in experimental hypothyroid female rats Afshin Hasanvand1, Raheleh Assaei2 1- Student Research Committee, Lorestan University of Medical Sciences, Khorramabad, Iran 2-Department of Physiology, School of Medicine, Lorestan University of Medical Sciences, Khorramabad, Iran BACKGROUND: Kisspeptins, a hypothalamic neuropeptide transmitter are targets for metabolic hormones, such as, thyroid hormones, which regulate reproductive function. Considering hypothyroidism, a huge metabolic disturbance, associated to hypogonadotropism. Defective gonadotropin secretion in hypothyroidism might affect through some drugs. PURPOSE: In this study, we evaluated the effect of peripheral kisspetin 10 administration on serum estradiol and progesterone and esterous cycle in experimental hypothyroid female rats. METHODS: The female wistar rats were divided into 4 groups: I. control+normal saline, II. control+kisspeptin group: rats used tap water and kisspeptin injected (50×10-8 nmol, i.p) daily for 9 days. III. hypothyroid+kisspeptin: Hypothyroid rats were injected kisspeptin (50×10-8 nmol, i.p) daily for 9 days. IV. hypothyroid+ normal saline: Hypothyroid rats, were injected normal saline daily for 9 days, in this group, normal saline were injected to euthyroid ovarectomized rats daily for 9 days. Hypothyroidism was induced by administration of methimazole at a concentration of 0.1 % in the drinking water for 14 days. The blood samples were collected in first day, fourth day and ninth day, 1 hour after injections. Serum estradiol and progesterone and estrous cycle were determined in experimental hypothyroid female rats. RESULTS: Estradiol and progesterone concentration decreased in hypothyroid animals and returned to normal level after injection of kisspeptin 10 after 4 and 9 days injection. Irregular estrous cycle resulted in hypothyroid rats returned to normal pattern after 5 days kisspeptin10 injection. CONCLUSION: Altogether, these data support that kisspeptin10 injection ameliorates the ovarian steroid and cyclicity of estrous cycle of hypothyroid rats. 192 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 268 Study of transcected sciatic nerve repair by chitosan/Polyethylene oxide scaffolds and human mesenchymal stem cells from Wharton's jelly in Wistar rats Moattari M1, Kouchesfahani H1, Kaka GH R2, Sadraie H2 1-Department of Biology, School of Medicine, Kharazmi University, Tehran, Iran 2-Research Scientific Center, Baghatallah Medical University, Tehran, Iran PURPOSE: The aim of this study was to determine the effects of chitosan/Polyethylene oxide scaffolds and human mesenchymal stem cells from Wharton's jelly on regeneration of the sciatic nerve injury in Wistar rats. METHODS: In this research 42 male adult rats weighting 200-250g were divided into six groups including-Normal group: healthy rats without any injuries. In Control group: sciatic nerve was cut in the middle region of thigh and epineuria were sutured. In Sham group: culture medium was injected on the sciatic nerve damaged. In Cs/PEO group: scaffold with a thin Cs/PEO were used around the sciatic nerve damaged. In cell group: 500000WJ-MSCs injected in the site of nerve damaged. In Cs/PEO with cell group: scaffold with a thin Cs/PEO and 500000WJ-MSCs were used around the sciatic nerve. After 8 weeks, the rate of recovery was studied by SFI (Sciatic Functional Index) and electroctrophysiological assessments. RESULTS: At the end of the eight week, SFI index showed improvement in Cs/PEO and WJ-MSCs group (P˂0.05). Mean SFI index showed relative improvement in treated groups compared to the control and sham groups. The results of latency and amplitude of electrophysiology showed that Cs/PEO and WJMSCs group was significantly better than control, sham, Cs and WJ-MSCs groups (P˂0.05). CONCLUSION: The results suggested that Cs/PEO had potential capability of regeneration of sciatic nerve injury. 193 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 269 Histomorphometric evaluation of chitosan/poly ethylen oxide scaffold and human mesenchymal stem cells from Wharton's jelly on the repair of transcected sciatic nerve in wistar rat Moattari M1, Kouchesfahani H1, Kaka GH R2, Sadraie H2 1-Department of Biology, School of Medicine, Kharazmi University, Tehran, Iran 2-Research Scientific Center, Baghatallah Medical University, Tehran, Iran PURPOSE: The aim of this study was to test the effects of chitosan-polyetylene (Cs/ PEO) scaffold and WJMSCs on sciatic nerve regeneration in rat. METHODS: In this study, forty-two male Wistar rats weighting 200-250 g were used. Animals were randomly divided into 6 experimental groups including normal, control, sham, Cs/PEO group, cell transplantation group and Cs/PEO and cell transplantation group. Normal group includes intact animals without sciatic nerve damage. In other groups sciatic nerve were cut in middle region of thigh and epineuria were sutured. Control group in which the nerve cut and was sutured. In sham group, culture medium was injected on the sciatic nerve damaged. In Cs/PEO group, scaffold with a thin Cs/PEO were used around the sciatic nerve damaged. In cell group, 500000 WJMSCs was injected on the sciatic nerve damaged. In Cs/PEO and cell group, scaffold with a thin Cs/PEO and 500000WJMSCs were used around the sciatic nerve damaged. The improvement rate was evaluated by histology. RESULTS: Mean number of nerve fibers in the Cs/PEO and WJMSCs groups significantly increased when compared to control and sham groups (P<0.05). Mean size of largest nerve fibers showed no significant decrease in all groups compared to control and sham groups (P<0.05). CONCLUSION: It seems that Cs/PEO and WJMSCs transplantation appears to be effective in the repair of damaged nerve. 194 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 270 A review on effectiveness of the combination of memantine plus vitamin D on cognition in patients with Alzheimer disease Mahdieh Rahimoghli, Ehsan Pourmemar, Maryam Dadashzade Tabriz University of Medical Science, Tabriz, Iran BACKGROUND: Alzheimer's disease (AD) is the leading cause of dementia. In addition to a decrease in brain cholinergic activity some of preclinical and experimental researches suggest that vitamin D enhances the efficacy of memantine in terms of neuronal protection and prevention of cognitive decline in AD. Thus this article reviews the last literatures and investigations of vitamin D and memantine therapy for AD and improvement of outcomes and outgoing efforts to translate the preclinical findings into clinical investigations. METHODS: For this purpose, we have searched the relevant articles (2010-2014) in scientific databases and eliminate repetitious and invalid articles. RESULTS: According to studied papers, AD is also marked by glutamatergic excitotoxicity that results in neuronal death. Memantine's modulation of NMDA receptors has been reported to prevent the neuronal necrosis induced by glutamatergic calcium neurotoxicity, but not the neuronal apoptosis resulting from oxidative stress. This observation calls for new drug regimen strategies based on memantine combined with molecules having antioxidant effects, in order to create a multi-target therapy to increase neuronal protection and prevent AD progression. On the other side, vitamin D is a secosteroid hormone that is suggested to have neuroprotective effects that include regulation of neuronal calcium homeostasis, as well as antioxidant, neurotrophic and anti-inflammatory properties. CONCLUSION: Accordingly it seems that the combination of memantine plus vitamin D may represent a new multi-target therapeutic class for the treatment of AD. 195 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 271 A review on CAD106 immunotherapy in Alzheimer’s disease Mahdieh Rahimoghli, Ehsan Pourmemar Student Neurosciences Research Committee (SNRC), Tabriz University of Medical Sciences, Tabriz, Iran BACKGROUND: Alzheimer disease (AD) is the most common cause of dementia and may contribute to 60-70% of cases. The cause and progression factors of AD are not well understood but have been thought that protein misfolding, beta amyloid (Aβ) plaques and tau proteins accumulation in brain are cardinal factors in this way. Some of preclinical and experimental researches suggest that Aβ immunization results in brain Aβ remove. CAD106 is a novel immunotherapy designed to stimulate the generation of antibodies against a small Aβ peptide fragment and Treatment with CAD106 induced an antibody response against Aβ and Qβ in most patients. Thus, this review focused on last literatures and investigations related CAD106 immunotherapy antibody response against Aβ in the brain. METHODS: For this purpose, we have searched the relevant articles (2000-2014) in scientific databases and eliminate repetitious and invalid articles. RESULTS: According to studied papers, CAD106 is immunotherapy designed to stimulate the generation of antibodies against a small Aβ peptide fragment (Aβ1–6) acting as a B-cell epitope and avoiding an Aβspecific c T-cell response. Immunization with CAD106 reproducibly prevented brain amyloid plaque accumulation in two transgenic mouse models of Alzheimer’s disease, with reductions of up to 80% in the plaque area compared with controls. CONCLUSION: It seems that, in the future, the CAD106 immunotherapy, antibody response against Aβ may provide a possible treatment option and help to AD progressing prevent. 196 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 272 A review on beta amyloid-based immunotherapy in Alzheimer’s disease Ehsan Pourmemar, Mahdieh Rahimoghl, Saeed Sadigh-Eteghad Neurosciences Research Center (NSRC), Tabriz University of Medical Sciences, Tabriz, Iran and Student Neurosciences Research Committee (SNRC), Tabriz University of Medical Sciences, Tabriz, Iran BACKGROUND: Alzheimer disease (AD) is the most common cause of dementia and may contribute to 60-70% of cases. The cause and progression factors of AD are not well understood but have been thought that protein misfolding, beta amyloid (Aβ) plaques and tau proteins accumulation in brain are cardinal factors in this way. Some of preclinical and experimental researches suggest that Aβ immunization results in brain Aβ remove. Thus, this review focused on last literatures and investigations related to passive or active immunotherapies targeting Aβ in the brain. METHODS: For this purpose, we have searched the relevant articles (2000-2014) in scientific databases and eliminate repetitious and invalid articles. RESULTS: According to studied papers, immunotherapy in AD aimed at Aβ covers 2 types of active and passive vaccination. In active vaccination against Aβ, patients receive injections of the antigen itself and in passive vaccination patients receive injections of monoclonal antibodies against Aβ. Three of the peptide vaccines for active immunizations, CAD106, ACC001 and Affitope are in phase II clinical trials. Three of the monoclonal antibodies namely, solanezumab, gantenerumab and crenezumab are in phase II and III clinical studies. CONCLUSION: It seems that, in the future, the Aβ-based immunotherapies may provide a possible treatment option and help to AD progressing prevent. 197 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 273 A review on role of Deferoxamine in preventing and treatments of stroke patients Safa Savadi Oskuee, Mona Zamanpour, Saeed Sadigh-Eteghad Neurosciences Research Center (NSRC), Tabriz University of Medical Sciences, Tabriz, Iran BACKGROUND: Stroke is the third leading cause of death in developed countries and it is the most common disabling neurological disorder in the world. Some of preclinical and experimental researches suggest that Deferoxamin (DFO) has preventing and treating effects on stroke. Thus, this article reviews the last literatures and investigations of DFO therapy for stroke and improves outcome, and ongoing efforts to translate the preclinical findings into clinical investigations. METHODS: For this purpose, we have searched the relevant articles (2001-2012) in scientific databases and eliminate repetitious and invalid articles. RESULTS: According to the studied papers, during a stroke, iron is released in brain cells as part of the free radical damage and DFO is a high affinity iron chelator. Also it may treating iron overload and may improve the patient’s condition via related mechanisms. CONCLUSION: It seems that DFO can be an important complementary therapy in stroke patients and improve the life quality of them. 198 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 274 Prescription of Lipitor or Atrova after Stroke Zahra Tolou_Ghamari Isfahan Neurosciences Research Centre, Faculty of Medicine, Isfahan University of Medical Sciences, Isfahan, Iran BACKGROUND: By independent method related to the levels of cholesterol, it seems that pretreatment with atorvastatin could improve ischemic brain damage after tentative stroke. Also in patients with previous stroke or transient ischemic attack pharmacotherapy with atorvastatin may improve renal function. PURPOSE: The aim of this study was to investigate the frequency of pre- or post- prescribed atorvastatin after stroke. METHODS: A cross-sectional study located at the Neurology ward of the Isfahan Alzahra Hospital was carried out on 50 patients with stroke. Demographical, clinical and pharmacological information were recorded in d-Base. RESULTS: Of the total population studied 60% were males. With a minimum of 31 and a maximum of 93, the mean age of patients was 73 years old. The frequency of prescribed atorvastatin in patients with stroke was 80%. Within this population 65% of males received atorvastatin (13 females versus 24 males). There was not a significant difference between the mean and the maximum age of males and females (p>0.05). The minimum age of male patient with a value of 31 years old was significantly lower than the female with a value of 52 years old (p<0.05). CONCLUSION: However neurological disorders are widespread globally but cerebrovascular diseases, reported for 55% of those disorders. Stroke could be mentioned as one the most important reason of enduring disability, cognitive and motor disorders and dementia. It could influence the task and composition of blood-brain hedge, the loss of cerebral blood flow regulation, oxidative stress, inflammation and the loss of neural associations. Finally, to protect patients from cerebral ischemia/reperfusion injury and to reduce inflammation and thrombogenesis effects, pre- or posttreatment with atorvastatin might promote anti-inflammatory and antioxidant effects in such patients. 199 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 275 Evidence-Based Preliminary Study of Antibiotics Pharmacotherapy in 50 Hospitalized Patients with Stroke Zahra Tolou_Ghamari, Mohamad-Reza Najafi, Fariborz Khorvash Isfahan Neurosciences Research Centre, Faculty of Medicine, Isfahan University of Medical Sciences, Isfahan, Iran BACKGROUND: According to previous publication stroke associated pneumonia could be accounted between 7-22% for early mortality after ischemic stroke. Rickettsial infections, Gram-negative bacilli included Pseudomonas aeruginosa, Escherichia coli and Klebsiella pneumonia and many other Infections might occur in 30% of stroke patients and could be connected with negative outcomes. PURPOSE: The aim of this preliminary study was to investigate the frequency and type of prescribed antibiotics in stroke. METHODS: A cross-sectional study located at the Neurology ward of the Isfahan Alzahra Hospital was carried out on 50 patients after stroke. Demographical, clinical and pharmacological information were recorded in d-Base. RESULTS: For 16 out of 50 patients antibiotic (32%) were prescribed. The minimum age of those who received antibiotics was 31 years old and the maximum age was 92 years. The mean age of all studied population was 76.5 years old. The highest rate for prescribed antibiotics was belonged to Ceftriaxone in 8 occasions. The lowest value for tendency toward prescription belonged to Cephalexin in 1 event. There were propensity for administration of Cefepime (n=2), Ceftazidime (n=2), Meropenem (n=2) and Clindamycin (n=3). CONCLUSION: The leading cause of death worldwide (30%) needs much more attention regarding to overall supervision and pharmacotherapy management in Iranian population. In addition to administration of sensible antipyretic, routine O2 supplementation and attention to early mobilization also should be considered vigilantly. Prescription of the most common beta-lactams such as Ceftazidime and Cefepime in patients with severe kidney disease after stroke should be always with cautious due to the potential neurotoxicity. Finally, to found whether protective antibiotic therapy in acute stroke could increase clinical outcome by inhibiting infection, further study in this direction recommended. 200 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 276 Neurologic Disorders: a Brief and Quick Review into the Domain of Pharmacotherapy Zahra Tolou_Ghamari Isfahan Neurosciences Research Centre, Faculty of Medicine, Isfahan University of Medical Sciences, Isfahan, Iran There is a great need for discovery of new drugs in clinical neurology such as seizure, multiple sclerosis, Parkinson, amyotrophic lateral sclerosis and many other neurological disorders. According to recent publication, by Shimohata T et al., in 2015, rotigotine and apomorphine are the new drugs that could be prescribed for patients with Parkinson. Kim W and colleagues in 2015 explained three oral drugs that have been approved by regulatory agencies for MS treatment: fingolimod, teriflunomide, and dimethyl fumarate. Regarding to the field of seizure Lee SK et al., in 2015 compared new versus old antiepileptic drugs (AEDs). Efficacy and pharmacokinetic behaviors has been the main concern of focus in this comparison. It seems that the efficacy of old generation is stronger than the new ones. The response to both generation of AED varies inter and intra individually. Epstein C et al., in 2015 published that anterior thalamic stimulation is associated with a 69% reduction in seizure frequency and a 34% serious devicerelated adverse event rate at 5 years. Werhahn KJ et al., in 2015 concluded that in the initial monotherapy of focal epilepsy in the elderly, 1-year retention to levetiracetam was higher compared to controlledreleased carbamazepine due to better tolerability. Retention of lamotrigine was intermediate and close to levetiracetam, but did not differ significantly from either comparator. A recent prospective study performed by Helfert S, et al., confirmed the concept of personalized pharmacological treatment of neuropathic pain. 201 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 NEUROMUSCULAR DISORDERS & NEUROPHYSIOLOGY 202 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 277 Ultrasound in Neuromuscular Disorders Hamid Ebadi1, CanadaVera Bril2 1-Department of Neurology, University of Calgary, Toronto, Canada 2- Department of Neurology, University of Toronto, Canada Ultrasound (US) has been widely used for the investigation of the neuromuscular disorders since last decade. Although it has been 30 years it was originally used for assessment of muscular dystrophies in children, new generation of higher frequency ultrasound machines have provided the opportunity of excellent visualization of small sized nerves such as sural and superficial peroneal. It has been shown that peripheral nerve ultrasound provides additional information to enhance clinical and EMG diagnosis in 40% of patients with focal neuropathies and in another 40% of them it confirms EMG findings. There are growing studies regarding the important role of US in inflammatory polyneuropathies such as CIDP and MMN. Muscle US has also been used for assessment of muscular dystrophies, detection of fasciculation (in some studies as sensitive as EMG), and as a guide for needle examination of diaphragm. This article will be reviewing clinical application of US in diseases of peripheral nerves and muscles. The main focus would be on the focal neuropathies which US is extremely useful but we will also discuss the recent trends and studies focused on polyneuropathies and myopathies. There are also videos and pictures of different interesting cases have been studied for the past two years in the US laboratory of the neuromuscular clinic of the University of Toronto. 203 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 278 Chronic inflammatory demyelinating polyradiculoneuropathy: what are the treatment options? Narges Karimi, Mahmood Abedini, Ashraf Zarvani Department of Neurology, Mazandaran University of Medical Sciences, Sari, Iran Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) has been used to identify patients with a chronically progressive or relapsing symmetric sensorimotor disorder with cytoalbuminologic dissociation and interstitial and perivascular endoneurial infiltration by lymphocytes and macrophages. It can be considered the chronic equivalent of acute inflammatory demyelinating polyradiculoneuropathy. CIDP is an autoimmune disorder, as demonstrated by a great deal of evidence, such as the finding of inflammation at the site of the lesion, response to immunomodulatory treatment and possibly the presence of autoantibodies against myelin antigens. Long-term prognosis of CIDP has been correlated to age at onset, response to treatment, and time from onset to the beginning of treatment: young patients with acute onset are more likely to respond to treatment than elderly ones and proximal impairment has been linked to a better prognosis than distal weakness. The main negative prognostic factors of CIDP are progressive course and axonal degeneration Peripheral nerve injury results from a synergistic interaction of cell-mediated and humoral immune responses directed against peripheral nerve antigens that have not been completely characterized. Since inflammation is the core of the disease, it is not surprising that immunomodulatory treatments have a positive effect. Nevertheless, it is not yet possible to predict disease progression on the basis of biological markers, because it is likely that under the general definition of “CIDP” a broad spectrum of different forms is included. Currently available treatments for CIDP are corticosteroids, immune globulin, plasma exchange, and chronic immunosuppressive agents. Treatment choice will depend on several variables such as initial disease severity, age, general health status, and potential contraindications. If a patient has only mild symptoms, a nerve biopsy could help to confirm the diagnosis and establish the need for intervention if axonal degeneration has already occurred. Mild symptomatic patients should be followed up regularly with repeated neurophysiological examinations since relapses are unpredictable and oblige to start the treatment. Treatment with corticosteroids or IVIG should be offered to patients with moderate or severe disability. First-line treatment choice depends on several factors, such as disease severity, the presence of a pure motor form of CIDP, contraindications and side effects of long-term therapy, costs, and local availability of PE or IVIG. An alternative approach, the subcutaneous administration of immunoglobulins (SCIG) via a small portable pump, has been initiated for these disorders. This regimen is well established for children. Application of SCIG with a small portable pump at home can significantly improve quality of life by reducing the frequency of hospitalizations and also reduced side effects and significant cost has demonstrated. Fingolimod is intended to be used as second line therapy for the treatment of patients with chronic inflammatory demyelinating polyneuropathy (CIDP). If licensed, fingolimod would offer an additional treatment option for patients with CIDP who currently have few (well-tolerated) effective therapies available. The tumor necrosis factorα antagonist etanercept is beneficial in rheumatoid arthritis. Three of 10 patients with treatment-resistant CIDP were considered to gain significant benefit from it. Rituximab is a chimeric (mouse/human) monoclonal antibody against CD20+ B lymphocytes. In CIDP, it was reported to have been beneficial in 12 of 17 patients in published case reports and small series. Autologous peripheral blood stem cell transplantation is an extreme form of immunosuppression in which the patient is treated with high dose cyclophosphamide and then granulocyte stimulating factor to allow harvesting of bone marrow stem cells from the blood. The patient is then treated with very high dose cyclophosphamide, anti-T cell antibodies and, in some regimes, whole body irradiation to ablate their immune system. 204 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 279 Comparison of diagnostic value of cross sectional area of median nerve in with highresolution ultrasound and electro-diagnostic study results in patients with carpal-tunnel syndrome Mohamadali Nahayati, Reza Boostani, Saedi Torbate Heydarieh University of Medical Sciences, Mashhad, Iran BACKGROUND: Carpal tunnel syndrome (CTS) is the most common form of peripheral nerve entrapment. Our aim was to assess the optimal discriminatory ultrasonography (USG) criteria in patients with CTS and to evaluate quantitative USG as a tool for diagnosis and treatment of patients in comparison with electrophysiological study (EDS). METHODS: Two hundred and five patients with CTS (30 male, 175 female) were assessed by clinicians in during 2009-2010 and underwent USG of the wrists. We considered each wrist separately in clinical diagnosis, thus in total 410 hands were analyzed in this work. EDS testing was done for all patients. RESULTS: In this study sensitivity of USG was 89% and specificity was 84% in right hand, and 90% and 89% for left hand, respectively. The false negative and false positive results of USG were 11%and 15%, respectively. There was a high degree of correlation between the conduction abnormalities of the median nerve as detected by EDS and the measurement of the cross-sectional area of the nerve by US (P<0.05). Various levels of disease severity could also be detected by USG. CONCLUSION: High-frequency USG examination of the median nerve and measurement of its crosssectional area should be strongly considered as a new alternative diagnostic modality for diagnosis and treatment of CTS, with evaluation of disease severity. 205 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 280 Carpal Compression test, Phalen’s test and Tinel’s test: which ones are better for Carpal Tunnel Syndrome? Mostafa Almasi Doghaee1, Reza Boostani2, Morteza Saeedi2, Amir Moghadam Ahmadi3 1-Rasool Akram Hospital, Department of Neurology, Faculty of Medicine, Iran University of Medical Sciences, Tehran, Iran 2-Department of Neurology, Faculty of Medicine, Mashhad University of Medical Sciences, Mashhad, Iran 3-Department of Neurology, Faculty of Medicine, Rafsanjan University of Medical Sciences, Rafsanjan, Iran BACKGROUND: Carpal Tunnel Syndrome (CTS) is one of the causes of hand dysfunction and because of its high prevalence, early diagnosis is very important. The aim of this study was to compare the sensitivity and specificity of the clinical tests of this syndrome. METHODS: Electrodiagnostic tests were performed on 89 consecutive patients suspected to CTS from 2011 to 2012, after assessing their medical history and undertaking physical examinations including Carpal Compression test (CCT), Tinel’s and Phalen’s tests. Then data analyzed with SPSS software and the sensitivity and specificity of clinical tests and the agreement between them were calculated. RESULTS: CTS was diagnosed in 80.9% of patients. There was no statistically difference in age, gender, employment and type of occupation between CTS and non-CTS patients. The highest sensitivities and specificities levels were obtained for the CCT (80.6% and 52.9%), Tinel/s (65.3% and 47.1%) and Phalen’s (59.7% and 35.3%) tests, respectively. There was a negative agreement between the Tinel’s and CCT tests in non-CTS patients (k= -0.524, P= 0.030) and a positive agreement between the Phalen’s and Tinel’s tests in CTS patients (k= 0.409, P<0.001). CONCLUSION: According to the findings of this study we suggest that clinicians should use the carpal compression test and Tinel’s test routinely for screening of patients suspected of suffering from CTS. 206 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 281 Serum level of Vitamin D in Patients with Acute Ischemic Stroke Farhad Assarzadegan Department of Neurology, Imam Hossein Hospital, Shahid Beheshti University of Medical Sciences, Tehran, Iran BACKGROUND: Vitamin D deficiency is common among the elderly and may contribute to cerebrovascular diseases. PURPOSE: We tested the hypothesis that low plasma concentrations of 25-hydroxyvitamin D are associated with increased risk of symptomatic ischemic stroke in patients with diagnosis of acute ischemic stroke. METHODS: In a case-control survey, 70 patients with diagnosis of acute ischemic stroke (AIS) admitted to Imam Hossein Hospital considered as case group and 72 patients with limbs trauma considered as control group. Matching between 2 groups was done based on age, sex, BMI, blood pressure and diabetes history. The serum level of vitamin D, calcium, P, ESR, CRP was measured in all participants. RESULTS: The serum level of calcium, P, ESR, CRP was not significantly different in both case and control groups. However, the serum level of 25(OH) D was significantly lower in patients with ischemic stroke (19.04±14.5 ng/ml) in comparison with control group (28.89±14.62 ng/ml; p <0.001). CONCLUSION: The serum level of vitamin D in patients with ischemic stroke was significantly lower than control group. These findings suggest that 25(OH) D may be an independent prognostic factor for ischemic stroke. However, evaluation level of 25(OH) D and severity symptoms and complication of stroke need to the more investigation. 207 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 MOVEMENT DISORDERS 208 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 282 Basal ganglia calcification due to Cockayne syndrome: case report Chitsaz A, Ansari B Department of Neurology, Isfahan University of Medical Sciences, Isfahan, Iran BACKGROUND: Cockayne syndrome is a rare, autosomal disorder characterized clinically by short stature, atypical retinopathy, enophthalmos, dental caries, skeletal and neurological abnormalities. We present case of 25-year-old male with Cockayne syndrome with neurological dysfunction and basal ganglia calcification. CASE PRESENTATION: The cachectic 25-year-old male presented with dysmorphic and neurological abnormalities, the child’s parents were both healthy. They have only one child. There was no parental consanguinity. The mother described her pregnancy was normal. She didn’t report any illness and hospitalizations during the pregnancy. Vaginal delivery was normal. The parents first became concerned about the child at approximately age 3 months because his head didn’t grow and his visual was decreased. His development continued to be delayed. The ophthalmologic evaluation revealed retinopathy and intermittent exotropia and cataract formation. His scalp was dry; his hair was dry, sparse and brittle. Dental caries was started from childhood and all of teeth decayed until 7 year’s old. No other significant abnormalities of the soft or hard structures of orofacial region were apparent. His skin was loose and his scrotum was small. Serial photographs show that Cockayne fancies. He walked unsupported at 15 years old. Irregular gait at 15 years was followed by spasticity and required wheelchair lengthening at 20 years. Hyperactive tendon stretch reflexes were obtained. There was frequent fall in these years. Intention tremor and titubation of the head were documented at 17 year’s old. Optic atrophy was detected at age 10 years, retinitis pigmentosa and lens opacities at age 13 years, Vision became limited at age 15 years and he was blind at age 20 years. In neurological examination, he was alert; spasticity in all of limbs with hyper reflexes was detected. Computed tomography revealed marked ventricular dilatation, cerebral and cerebellar atrophy and calcification of basal ganglia. Magnetic resonance imaging was showed white matter demyelination, brain atrophy and basal ganglia calcification. Tests for lipid profile, liver enzyme, renal function, thyroid function, pyruvate, lactate and vascular tests were normal. Parathyroid hormones were small elevation. (PTH=85 normal range was 14-74) Because of dysmorphic features, dental caries, ophthalmological abnormalities and basal ganglia calcification, we assigned him to the Cockayne syndrome. CONCLUSION: Cockayne syndrome is a rare autosomal recessive disease but dental caries are common in this syndrome. So in patient with basal ganglia calcification with typical dysmorphic feature, visual, cutaneous and neurological findings with prominent dental caries, we should considered Cockayne syndrome and further study to evaluation of genetic test should be performed. 209 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 283 Evaluating function of parathyroid gland axis in Parkinson's disease Ahmad Chitsaz, Rokhsareh Meamarit Esfahan University of Medical Sciences, Isfahan, Iran BACKGROUND: Parathyroid hormone (PTH) levels can make changes in serum biomarkers and effect progression symptoms of many diseases like Parkinson's disease (PD). According to previous studies it seems that parathyroid gland function is effective in severity of symptoms of PD. This study aimed to explore the role of PTH in PD, progression regarding the lack of researches in this field in the Middle East. METHODS: This case control study was carried out in Alzahra hospital, Isfahan, Iran. 125 patients with PD diagnosed by experienced neurologists and 112 healthy controls matched for age and gender with patient group. They were asked to participate during September to November 2011. At base line, the severity of PD was evaluated with motor part of the unified PD rating scale III (UPDRs III), the level of PTH, calcium, phosphorus, and 25- hydroxyl vitamin D were measured. RESULTS: The mean±SD of PTH level was significantly lower in patients group (45.2±18.8 IU/I), compared to controls (70.8±28.5 IU/I; P=0.0001); There are not any significant correlation between hormone level, elements and severity of PD. We observed that men had motor risk of PD than women (odds ratio=2.53, [CI: 1.27-5.03)], P=0080). CONCLUSION: This study could not confirm the relationship between the level of parathyroid gland function, the level of serum PTH and severity of motor symptoms in PD. It could be explained by the lack of a sufficient number of Hypo and hypercalcemia, phosphatemia and hypoparathyroidism in our samples. 210 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 NEUROMODULATION & NEUROREHABILATION 211 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 284 Augmentative and Alternative Communication (AAC) for adults with aphasia Elham Seihei1, Alireza Mollaei2 1-Musculoskeletal Rehabilitation Research Center, Ahvaz Jundishapur University of Medical Sciences, Ahvaz, Iran 2-Golestan Hospital, Ahvaz Jundishapur University of Medical Sciences, Ahvaz, Iran BACKGROUND: Aphasia is the result of damage to the brain's language centers affecting production, comprehension, or both, and can cause severe, chronic language impairment Individuals with aphasia often communicate using a combination of speech, gestures, and aided communication; the proportion of each may change as the person recovers, and depends on the context and the individual's skills. PURPOSE: The aim of this review is Augmentative and Alternative Communication (AAC) for adults with aphasia. METHODS: ScienceDirect, Pubmed (2000 through 2015) were searched for English-language studies using a list of keywords. The books about AAC, neurology and speech-language pathology were studied too. RESULTS: Depending on their language and cognitive skills, those with aphasia may use AAC interventions such as communication and memory books, drawing, photography, written words, speech generating devices and keyboards. Visual scene displays have been used on communication devices with adults who have chronic, severe aphasia; these feature photos of people, places or events that are meaningful to the individual and facilitative of communicative interaction. Approaches such as "Supported Conversation for Adults with Aphasia" train the communication partners to use resources such as writing key words, providing written choices, drawing, and using items such as photographs and maps to help the individual with aphasia produce and comprehend conversation. Published data support the use of aided and unaided AAC with adults with severe aphasia in controlled treatment contexts. Reported gains in communication typically have not generalized to everyday settings. CONCLUSION: AAC has much to offer for supporting aphasic communication, not only for people with a very severe aphasia, who do not benefit from disorder‐oriented therapy, but also for people with a moderate or mild aphasia. Research into AAC and aphasia, focusing on functional use, is needed in order to build and refine communication aids that are easy to use and can be tailored individually. 212 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 285 How do ankle muscles activities in post stroke patients alter while locomotors intensity changes? Roghayeh Mohammadi, Mohammad Reza Hadian, Saeed Talebian Moghadam, Chetan P. Phadke, Mir Saeed Yekaninezhad Tehran University of Medical Sciensces, Tehran, Iran BACKGROUND: Plantar flexor muscles produce propulsive force in the second half of stance phase, obviously muscle weakness lead to progressive decline in force production and adequate propulsion at push off phase of gait following stroke. PURPOSE: This study examined whether walking on an inclined surface increased muscle activity in stroke patients and whether it resulted in increased muscle activity during walking speed increasing. METHODS: To test these hypotheses, 19 post-stroke patients (14 males and 5 females) walked on a standard treadmill at three grades and three different speeds. We quantified the puss off phase electromyographic activities of the ankle muscles, Medial Gastrocnemius (MG), and Tibialis anterior (TA). RESULTS: MG muscle activity at the affected side in the push off phase increased when walking speed went up in any slope (p<0.05). Also its activity was significantly greater at 3 and 6 degree incline compared with no incline in the non paretic side of people with stroke (P<0.05) but not in the paretic side (P>0.05). No change was seen in TA muscle activity in the paretic side of people with stroke (P>0.05) but reduction in its activity was seen on non paretic side with increasing walking speed (P<0.05). On average, compared to level walking, MG muscle activity increased to walk up higher grade on non affected side of patients. In contrast, changes in muscle activations on paretic side were seen with faster walking speed. CONCLUSION: We conclude that both sides of the patients apply distinct muscle recruitment strategies generally across walking speeds and progressively with steeper grade. 213 22nd Congress of Neurology & Clinical Electrophysiology of Iran 12-15 May 2015 286 Subcortical Encoding of Speech Cues in Children with Attention Deficit Hyperactivity Disorder Zahra Jafari1, Saeed Malayeri Audiologist2, Reza Rostami3 1-Department of Basic Sciences in Rehabilitation, School of Rehabilitation Sciences, Iran University of Medical Sciences (IUMS), Tehran, Iran 2-Newsha Hearing Institute, Tehran, Iran 3-Department of Psychology, Tehran University, Tehran, Iran BACKGROUND: There is little information about processing of nonspeech and speech stimuli at the subcortical level in individuals with attention deficit hyperactivity disorder (ADHD). The auditory brainstem response (ABR) provides information about the function of the auditory brainstem pathways. PURPOSE: We aim to investigate the subcortical function in neural encoding of click and speech stimuli in children with ADHD. METHODS: The subjects include 50 children with ADHD and 34 typically developing (TD) children between the ages of 8 and 12 years. Click ABR (cABR) and speech ABR (sABR) with 40 ms synthetic /da/ syllable stimulus were recorded. RESULTS: Latencies of cABR in waves of III and V and duration of V-Vn (P=0.027), and latencies of sABR in waves A, D, E, F and O and duration of V-A (P=0.034) were significantly longer in children with ADHD than in TD children. There were no apparent differences in components the sustained frequency following response (FFR). CONCLUSION: We conclude that children with ADHD have deficits in temporal neural encoding of both nonspeech and speech stimuli. Significance: There is a common dysfunction in the processing of click and speech stimuli at the brainstem level in children with suspected ADHD.
