While welcoming a new baby is a joyous milestone, the physical and emotional toll of recovery can sometimes spark serious mental health challenges. This complex reality captured national attention during the trial of Lindsay Clancy, a Boston-area mother whose case brought light to the extreme end of perinatal mood disorders. Prosecutors argued her actions were premeditated, whereas her defense maintained that she was suffering from severe, untreated postpartum psychosis when she harmed her three children in 2023.

To make sense of these conditions, it helps to view perinatal mental health as a broad spectrum. On one end are the common “baby blues” and postpartum depression, which affects about one in seven mothers with deep sadness, exhaustion and intense anxiety. At the far end sits postpartum psychosis, a rare psychiatric emergency affecting only one to two out of every thousand births that causes a person to lose touch with reality.

What is postpartum psychosis?

Perinatal mood and anxiety disorders comprise a spectrum of emotional and psychological disorders that can arise during or after pregnancy.

  • Postpartum “Baby Blues”: A temporary emotional upswing or downswing seen in up to 80% of new moms that goes back to normal within two weeks after the baby is born, according to Healthline.
  • Postpartum Depression (PPD): A moderate to severe clinical depression in which about 10-15% of mothers experience a persistent sad mood, low self-worth, high levels of fatigue, sleep problems and impaired infant bonding, per the Cleveland Clinic.
  • Postpartum Psychosis (PPP): As the European Society of Medicine notes, this is a serious psychiatric emergency with a sudden onset of mania, paranoia, bizarre delusions, auditory or visual hallucinations and severe confusion.

According to advocacy groups such as Postpartum Support International, postpartum psychosis is not always diagnosed because it is not a separate disorder in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), which can cause practitioners to misidentify the early signs.
