Applies to: Depressive disorders · Bipolar disorders
Deciding signal: Timing around pregnancy and birth changes safety assessment, treatment context, and family support needs.
Ask this: Did the mood episode begin in the peripartum window, and are bipolarity, psychosis, and immediate safety actively assessed?
Wording outcome: Major depressive disorder, single episode, with peripartum onset

The episode clearly pre-dated pregnancy without a meaningful peripartum onset or recurrence.
Symptoms are better explained by transient adjustment alone, while still recognising that distress may require care.

Fit and exclusions

Start with the deciding signal, then test chronology, competing explanations, and the effect on diagnostic wording.

Episode onset is clearly linked to pregnancy or the early post-birth period.
The assessment distinguishes depressive, manic-spectrum, psychotic, anxiety, trauma, and adjustment presentations.
Parent, infant, sleep, feeding, support, and safeguarding needs are considered together.

Coordinate timely perinatal mental health care; new psychosis, mania, or severe deterioration requires urgent escalation.

Focus: Mood-episode onset around pregnancy or birth
Time course: Defined by episode onset, not simply current parenting status
Look for: Onset timing, bipolar indicators, psychosis, sleep loss, safety and support
Avoid: Do not treat all post-birth distress as unipolar depression
