Osborne addresses mood and anxiety symptoms during pregnancy and postpartum. This lecture focuses on the clinical presentation of perinatal mood and anxiety syndromes, touches on the reasons perinatal women are especially vulnerable, and offers up-to-date, evidence-based recommendations for treatment.
