- In Canada:
- depressive disorders are MOST common in adolescence and early adulthood (15-24 years of age)
- Through adolescence and adulthood (15-64 years of age) WOMEN have a higher prevalence of depressive disorders compared to men
- older adults (65 and older) have the lowest prevalence of depressive disorder, and no significant difference between men and women
Major Depressive Disorder Specifiers
- with anxious distress
- with mixed features
- with melancholic features
- with atypical features
- with mood-congruent features
- with mood-incongruent features
- with catatonia with peripartum onset
- used to be postpartum, now considered a special case as for the next below - with seasonal pattern (recurrent episodes only)
Risk Factors for depression:
- age
- 20s and 30s
- SES status
- marital status
- women are nearly twice as likely as men to develop major depression

Postpartum Depression
-correctly termed: MDD with Peripartum Onset
-persistent and severe mood changes that occur after childbirth
In fact, about half begin in the late stages of pregnancy (hence to the switch to peripartum)
-Prevalence 10-15%
Persistent Depressive Disorder (Dysthymia)
