Pathophysiology & Risk Factors

Postpartum mood disorders fall on a severity spectrum: self-limiting baby blues (up to 80% of mothers, onset 2-3 days, resolves by day 10-14) -> postpartum depression (10-15%, persists beyond 2 weeks with functional impairment) -> postpartum psychosis (1-2 per 1,000 births, a psychiatric emergency with a break from reality). Risk factors overlap across the spectrum.

Interventions & Priorities

Assess suicidal and infanticidal ideation

Never leave alone with the newborn

Activate 911 for active psychosis

Acute delusions = psychiatric emergency, not an office visit

Administer EPDS screening

PPD is treatable, not a personal failing

Guilt keeps mothers from self-reporting

Hallucinations Hallmark

Postpartum psychosis = psychiatric emergency

Delusions Hallmark

Disorganized behavior with infant

Thoughts of self-harm

Thoughts of harming the infant

Endangering behavior toward newborn

e.g., holding infant near open window

Clinical Pearl

If it lasts past two weeks, it's not the blues — and if reality breaks, it's an emergency, not severe depression.

Postpartum Depression & Psychosis

"Baby blues" resolve on their own — postpartum depression and psychosis do not. Mistaking one for the other delays treatment and puts both mother and newborn at risk.

Postpartum mood disorders exist on a severity spectrum. Baby blues affect up to 80% of new mothers, onset within 2–3 days after delivery, and resolve by day 10–14 without treatment — tearfulness, mood swings, and irritability are normal and self-limiting. Postpartum depression (PPD) is a clinical disorder affecting 10–15% of mothers, onset anytime within the first 12 months but commonly by 4–6 weeks. Hallmarks include persistent sadness, feelings of worthlessness or guilt, inability to care for the infant, sleep and appetite disturbances unrelated to newborn care, and possible suicidal ideation. The Edinburgh Postnatal Depression Scale (EPDS) is the validated screening tool; a score of 10 or higher warrants further evaluation. Postpartum psychosis is rare (1–2 per 1,000 births) but a psychiatric emergency, typically emerging within the first 48–72 hours to 2 weeks. It presents with hallucinations, delusions, severe confusion, paranoia, and disorganized behavior. Risk of infanticide and suicide is real — the patient requires immediate psychiatric referral and should never be left alone with the newborn. Risk factors for both include history of depression or bipolar disorder, lack of social support, complicated delivery, and NICU admission.

Key Distinctions

Don't confuse baby blues (self-limiting by 2 weeks, no treatment needed) with PPD (persists beyond 2 weeks, requires intervention). Students often classify postpartum psychosis as severe PPD — psychosis involves a break from reality (hallucinations, delusions) and is a separate emergency. PPD screening preferentially uses the EPDS; while the PHQ-9 is validated, the EPDS is the recommended postpartum-specific tool.

Clinical Pearl

If it lasts past two weeks, it's not the blues. Screen every postpartum patient with the EPDS — mothers with PPD rarely self-report because guilt keeps them silent.
