Case 3: Brief Psychotic Disorder with Postpartum Onset

Patient Presentation

Demographics: 28-year-old female

Chief Complaint: "She's talking about the baby being special and hasn't slept in days." (per husband)

History of Present Illness: A 28-year-old woman, gravida 1 para 1, is brought to the emergency department by her husband 5 days postpartum. She had an uncomplicated pregnancy and vaginal delivery of a healthy baby boy. Her husband reports that she seemed normal for the first 2 days but then stopped sleeping entirely despite exhaustion. She became increasingly agitated and began making statements that their baby was "chosen by God for a special mission" and that she could communicate with him telepathically. She believes she can hear angels singing around the baby. She has been unable to care for the infant appropriately - she attempted to keep the baby awake through the night because "he needs to receive the messages." Last night, she tried to take the baby outside in freezing weather because "the angels told me the stars would bless him." Her husband intervened and brought her to the ED. She has no prior psychiatric history and was psychiatrically healthy throughout her pregnancy. No substance use. Family history is negative for psychiatric illness.

Physical Examination:

  • Vital signs: BP 140/90, HR 110, T 37.8C
  • General: Agitated, sleep-deprived appearance, pressured speech
  • Neurological: No focal deficits
  • Postpartum exam: Normal uterine involution, no signs of infection

Mental Status Examination:

  • Appearance: Disheveled, appears exhausted but hyperactive
  • Behavior: Agitated, pacing, intrusive
  • Speech: Pressured, rapid, difficult to interrupt
  • Mood: "Blessed, chosen"
  • Affect: Elevated, labile, incongruent at times
  • Thought process: Tangential with flight of ideas
  • Thought content: Grandiose delusions (baby is special, chosen), religious delusions; denies SI but judgment severely impaired
  • Perceptions: Auditory hallucinations (angels singing), possible visual hallucinations (sees "light" around the baby)
  • Insight: Absent
  • Judgment: Severely impaired - endangered infant

  • TSH: Normal
  • CBC: Mild leukocytosis (may be normal postpartum)
  • CMP: Normal
  • Urinalysis: Normal, no infection
  • B12, folate: Normal
  • Urine drug screen: Negative

Diagnosis: Brief Psychotic Disorder with peripartum onset (also known as postpartum psychosis)

Treatment:

  • Admitted to inpatient psychiatry with mother-baby unit capabilities
  • Started olanzapine 10 mg at bedtime (addresses psychosis, aids sleep)
  • Added lorazepam 1 mg Q6H PRN for agitation
  • Infant cared for by husband and nursing staff; supervised mother-baby contact only
  • Supportive care emphasizing sleep restoration
  • Rapid improvement over 3-4 days as sleep normalized
  • At 1 week: Psychotic symptoms resolved, appropriate maternal behavior
  • Transitioned to quetiapine for maintenance
  • Discharged at 10 days with close outpatient follow-up
  • Plan for medication continuation for at least 6-12 months
  • Discussed risk of recurrence with future pregnancies (approximately 25-50%)

Clinical Pearl: Postpartum psychosis is a psychiatric emergency with onset typically within the first 2 weeks postpartum. It occurs in approximately 1-2 per 1000 deliveries and is distinct from postpartum depression. Risk of infanticide is approximately 4%, necessitating thorough safety assessment and often supervised infant contact initially. Most cases resolve relatively quickly with treatment, but there is significant recurrence risk with future pregnancies. The presentation often resembles mania with psychotic features, and there is a strong association with underlying bipolar disorder (approximately 50% will be diagnosed with bipolar disorder on follow-up).
