DSM-5 Diagnostic Criteria – Major Depressive Episode (MDD)
Diagnostic Criteria – MDD
* symptoms cause?
* not attributable to?
* not better explained by?
* has never been?
- symptoms cause clinically significant distress or impairment in social, occupational, or other important areas of functioning
- not attributable to the physiological effects of a substance or another medical
condition - not better explained by another psychiatric illness
- has never been a manic episode or a hypomanic episode
Monoamine Hypothesis of Depression
- Depression due to deficiency of monoamine neurotransmitters (NT)
– norepinephrine
– serotonin
- Evidence of monoamine hypothesis
– Depletion of NT induces depression
– Antidepressants increase levels of NT
– Onset of antidepressant activity (decrease in depressive symptoms) is correlated with down-regulation of receptors
