    • 10-item self-report questionnaire.
    • Score ≥10 suggests possible depression; ≥13 indicates probable depression.
  • PHQ-9 (Patient Health Questionnaire-9): Also commonly used.

⭐ Any positive score on EPDS Question 10 (suicidal ideation) mandates immediate, thorough evaluation, irrespective of total score.

Clinical Features & Diagnosis - Unmasking the Struggle

• Postpartum Depression (PPD):
  • Onset: Usually 1-4 weeks postpartum (up to 1 year).
  • DSM-5: Major Depressive Episode (≥5 symptoms, ≥2 weeks).
    • Key: Depressed mood, anhedonia.
    • Plus: Sleep/appetite issues, fatigue, guilt, ↓concentration, suicidal thoughts.

Management & Therapeutics - Paths to Wellness

• Goal: Maternal recovery & safe mother-infant interaction.
• Mild-Moderate PPD:
  • Psychotherapy (CBT, IPT) is primary.
  • Support groups, lifestyle changes.
• Moderate-Severe PPD:
  • SSRIs (Sertraline 50-200mg, Paroxetine) are first-line drugs.
  • TCAs (Nortriptyline) if SSRIs not suitable.
  • Benzodiazepines (Lorazepam) short-term for anxiety; use with caution if breastfeeding.
• Postpartum Psychosis (Emergency):
  • Immediate hospitalization.
  • Antipsychotics (Olanzapine), Mood stabilizers (Lithium - check levels, Valproate - risks).
  • ECT for severe/refractory cases.
• ⭐ Breastfeeding & SSRIs:

  Sertraline & Paroxetine: generally preferred SSRIs due to low milk transfer & safety data. Monitor infant.

High‑Yield Points - ⚡ Biggest Takeaways

• Postpartum blues is common, self-limiting (peaks day 3-5, resolves by 2 weeks); reassurance suffices.
• Postpartum Depression (PPD): onset within 4 weeks (up to 1 year). Screen with EPDS (score ≥10-13). Treat with SSRIs (sertraline) & psychotherapy.
• Postpartum Psychosis: psychiatric emergency! Rapid onset (<2 weeks), delusions/hallucinations. Immediate hospitalization vital; high suicide/infanticide risk.
• Risk factors: prior psychiatric illness, poor social support, stressful life events.
• Always rule out postpartum thyroiditis as a differential diagnosis for mood changes.
