Cognition in MDD (Guy Goodwin, ECNP 2013)
• Hot processing= emotional processing- focus

• Cold processing=non-emotional cognitive
distortion: executive Functioning, learning,

“Cold” processing is critical for functioning
Domains of cognition
DOMAIN
DESCRIPTION
Attention
The ability to focus and sustain attention
Memory / learning
Including episodic memory (relating to past or future events),
verbal memory / learning and visuo-spatial memory / learning
Executive functioning
The ability to monitor and regulate cognitive processes, employing attention, planning,
working memory, mental flexibility, inhibition, task initiation and monitoring, multi-tasking
and decision-making
Psychomotor speed
The speed at which the brain controls the body to perform physical tasks

• Does the cognitive impairment occur
before the mood symptoms?
II
• Is the time course of cognitive
normalization delayed in relation to
remission?
III
• Is long-lasting cognitive impairment a
predictor for enhanced relapse risk or for
new episodes?

Assessing cognitive dysfunction using
depression rating scales
HAM-D
MADRS
● Retardation (slowness of thought
and speech, impaired ability to concentrate,
decreased motor activity)
● Difficulties in concentrating and sustaining
thought, which reduces ability to read or hold
a conversation
Beck Depression Inventory
Patient Health Questionnaire
● I have greater difficulty in making decisions
than I used to
● Trouble concentrating on things, such as
reading the newspaper or watching TV
Standard depression scales do not assess all the cognitive domains
