About this term
- Quick definition
- A major depressive episode that begins during pregnancy or in the year after birth.
- Full clinical definition
- In the DSM-5-TR, postpartum depression is captured by the "with peripartum onset" specifier of major depressive disorder, applied when the episode begins during pregnancy or in the four weeks after delivery. In clinical practice and in major obstetric guidelines (ACOG), the term is used more broadly for major depressive episodes that begin during pregnancy or at any point in the first year after birth (perinatal depression). It is distinct from the "baby blues," a transient, mild mood disturbance that resolves within about two weeks of delivery without specific treatment.
- Epidemiology
- Postpartum depression affects roughly 1 in 7 birthing parents in the United States (ACOG, 2018). Rates are higher in birthing parents with prior depression, prior postpartum mood episodes, limited social support, financial strain, pregnancy or delivery complications, or a history of trauma. Partners, including non-birthing partners, can also develop perinatal depression.
- What it can feel like
- Persistent low mood, anhedonia, sleep disturbance beyond what the newborn explains, intrusive negative thoughts about the baby, overwhelming guilt, intense self-doubt about parenting, withdrawal from the baby and from family, and in severe cases thoughts of self-harm or harming the baby. Many patients describe the symptoms as colliding with intense expectations about how this period was supposed to feel.
- Why it matters
- It is common and treatable. It is not a failure of love or parenting. Untreated postpartum depression is associated with poorer infant feeding, infant attachment, and child development outcomes. Suicide is a leading cause of maternal death in the year after birth (CDC Maternal Mortality reports). Recognition and treatment in the first weeks change the trajectory.
- How clinicians assess it
- The Edinburgh Postnatal Depression Scale (EPDS) is the most commonly used screening tool, and the PHQ-9 is also used. Both ACOG and the U.S. Preventive Services Task Force (USPSTF) recommend universal screening for depression during pregnancy and in the postpartum year. A positive screen leads to a clinical assessment that includes thoughts of self-harm and thoughts of harm to the infant, and that screens for postpartum psychosis (a psychiatric emergency).
- Treatment implications
- Psychotherapy with strong evidence (CBT, interpersonal therapy) is first-line for mild to moderate postpartum depression. SSRIs are often used for moderate to severe postpartum depression and are generally compatible with breastfeeding (sertraline is commonly preferred). Brexanolone (intravenous) and zuranolone (oral) are FDA approved for postpartum depression. Severe postpartum depression with psychosis or suicidality is treated as an emergency, often with hospitalization. Partner involvement, social support, sleep protection, and coordinated obstetric and psychiatric follow-up improve outcomes.
