Overview

Expert consensus review reveals neurobiological overlap with bipolar disorder in postpartum women, highlighting shared genetics and treatment response to support distinct classification.

Key Points

  • Postpartum psychosis exhibits a distinct clinical phenotype within the bipolar spectrum, featuring rapid onset alongside severe affective and psychotic symptoms after delivery.
  • In 50% of first-onset postpartum psychosis cases, patients experience a first onset of bipolar disorder, showing robust therapeutic response to lithium and electroconvulsive therapy.
  • Expert consensus panel evaluation supports formal DSM-5 and ICD-11 diagnostic classification within bipolar disorders, highlighting shared genetic risk architecture to improve care.
