Recognizing and Managing Postpartum Psychosis: A Clinical Guide for Obstetric Providers.

Postpartum psychosis is a psychiatric emergency that affects 1 to 2 per 1000 women. Key clinical features include mood fluctuation, abnormal thoughts or behaviors, and confusion. Women with a history of bipolar disorder are at heightened risk, as are first-time mothers; current research on the causes focuses on biological triggers, such as immune dysregulation. Women with postpartum psychosis require inpatient hospitalization and should be treated with lithium, antipsychotics, and benzodiazepines.
