Referral and warning signs
When to refer
IMMEDIATE referral to hospital (H) with psychiatric capabilities is mandatory for ALL suspected cases of postpartum psychosis.
Red flags
- Acute onset of confusion, delusions, hallucinations, or bizarre behavior postpartum
- Rapidly shifting mood postpartum
- Thoughts or commands to harm self or baby
- Severe insomnia or agitation postpartum
- History of bipolar disorder or previous postpartum psychosis
Signs and symptoms
- Rapid onset (usually within days to 2 weeks postpartum, sometimes within 48-72 hours).
- Symptoms often resemble severe bipolar episode (manic, depressed, or mixed) with psychosis:
- - Mood: Rapidly shifting mood (elation, depression, irritability), confusion, perplexity.
- - Behavior: Restlessness, insomnia, agitation, disorganized behavior, impaired judgment.
- - Thought/Perception: Delusions (often related to the baby - e.g., baby is defective, evil, special/divine, or not hers), Hallucinations (often auditory commands to harm self/baby), disorganized thinking.
- Cognitive impairment, disorientation.
- High risk of suicide and infanticide.
Risk factors
- Personal history of bipolar disorder (highest risk factor).
- Personal history of previous postpartum psychosis.
- Personal history of schizophrenia or schizoaffective disorder.
- Family history of bipolar disorder or postpartum psychosis.
- First pregnancy (primiparity).
- Sleep deprivation.
- Obstetric complications (less clearly established).
- Discontinuation of psychiatric medication during pregnancy.
Diagnosis
Clinical assessment
Diagnosis based on acute onset of severe psychiatric symptoms (mood disturbance, psychosis, behavioral disorganization) within the early postpartum period. Requires urgent psychiatric assessment. Rule out delirium due to postpartum medical complications (infection, hemorrhage, eclampsia, thyroiditis, substance withdrawal). Differentiate from severe postnatal depression (which typically lacks psychosis and rapid mood shifts) and postnatal anxiety.
Investigations
- History (personal and family psychiatric history is key).
- Mental state examination.
- Physical examination and investigations to rule out organic causes:
- - CBC, electrolytes, renal function, LFTs.
- - Thyroid function tests (postpartum thyroiditis).
- - Toxicology screen if substance use suspected.
- - Consider infection screen (if fever).
- - Consider brain imaging if neurological signs present.
Diagnostic criteria
Onset of psychotic and/or severe mood symptoms (meeting criteria for manic, mixed, or depressive episode) within the first few weeks postpartum.
Management
Non-pharmacological management
- Psychiatric Emergency - Requires Urgent Hospitalization (Psychiatric Unit if possible).
- Ensure safety of mother and infant (may require separation initially and supervised contact).
- Supportive environment.
- Psychoeducation for patient and family.
- Involve partner/family in care planning and support.
- Social work support.
- Electroconvulsive Therapy (ECT) can be highly effective and rapidly acting, especially if severe, life-threatening, or catatonic features (Specialist level).
Pharmacological treatment
- Treat any underlying medical condition (e.g., infection).
- Medications usually required urgently:
- - Antipsychotics: To manage psychosis and agitation. Haloperidol (e.g., 5-10mg PO/IM), Chlorpromazine (e.g., 100-200mg PO/IM), or atypical antipsychotics (Olanzapine, Risperidone) are effective.
- - Mood Stabilizers: Often needed, especially if underlying bipolar disorder suspected/confirmed. Lithium or Valproate commonly used (start after acute stabilization). Caution with breastfeeding: Monitor infant if mother on Lithium/Valproate; some antipsychotics considered safer (discuss risks/benefits).
- - Benzodiazepines: May be used short-term for severe agitation or insomnia (e.g., Diazepam 5-10mg IV/PO/Rectal, Lorazepam).
- Follow specific Ugandan treatment algorithms/guidelines. Combination of antipsychotic + mood stabilizer often used.
Monitoring
Close monitoring of mental state, mood, psychotic symptoms, behavior, sleep. Monitor for risk of harm to self or infant. Monitor vital signs. Monitor for side effects of medications (EPS, sedation). Monitor mother-infant interaction.
Complications
- Suicide
- Infanticide
- Impaired mother-infant bonding
- Relapse of underlying psychiatric disorder
- Long-term functional impairment if not treated effectively
- Stigma
Prevention
- Identify women at high risk during pregnancy (history of bipolar disorder, previous PP psychosis).
- Close monitoring postpartum for high-risk women.
- Consider prophylactic mood stabilizer treatment immediately postpartum for women with bipolar disorder (specialist decision).
- Ensure adequate sleep and psychosocial support postpartum.
- Early detection and prompt treatment of symptoms.
Patient education
- Explain the condition as a severe but treatable postpartum illness.
- Reassure that it is not the mother's fault.
- Explain the need for hospitalization and medication.
- Discuss safety concerns regarding infant care initially.
- Involve family heavily in education and support.
- Discuss long-term treatment and risk of recurrence in future pregnancies.
Uganda-specific notes
Postpartum psychosis may be attributed to spiritual causes, delaying appropriate care. High risk of harm if not recognized and managed urgently. Access to inpatient psychiatric care is limited. Haloperidol, Chlorpromazine, Diazepam are more likely available than atypicals or mood stabilizers like Lithium/Valproate. Careful consideration needed regarding breastfeeding and medication safety.
