Postpartum Psychosis

Postpartum depression is a depressive illness after childbirth, marked mainly by persistent low mood or loss of interest. Postpartum psychosis is a rarer, acute psychiatric condition in which contact with reality is impaired, often alongside severe mood disturbance, confusion or behavioural change.

Core clinical distinction

The decisive distinction is the presence or absence of psychosis, rather than the intensity of ordinary postpartum distress alone.

• Postpartum depression typically causes persistent sadness, loss of interest, guilt, hopelessness, anxiety and disturbances of sleep or appetite, while reality testing usually remains intact.
• Postpartum psychosis may involve delusions, hallucinations, disorganised behaviour, severe agitation, mania, rapidly changing mood or confusion.
• Depression can occasionally include psychotic symptoms. Such a presentation requires urgent assessment and is not treated as uncomplicated postpartum depression.

Onset and clinical assessment

Postpartum psychosis usually has a sudden onset, commonly within the first two weeks after childbirth. Postpartum depression often develops more gradually, but timing can overlap and therefore cannot by itself establish the diagnosis.

• Diagnosis requires a clinical assessment of mood, thought content, perception, cognition, behaviour and the mother's ability to care safely for herself and the infant.
• Clinicians also assess previous bipolar or psychotic illness and exclude medical, neurological or substance-related causes of an altered mental state.
• Depression screening questionnaires can identify depressive symptoms, but they do not replace assessment for psychosis, mania or immediate risk.

Difference in urgency

Postpartum psychosis is a psychiatric emergency because impaired judgement, delusions or hallucinations may create an immediate risk of suicide, accidental harm or harm to the infant. It requires urgent specialist assessment and often hospital care, whereas postpartum depression is managed according to severity but also needs emergency intervention when suicidal intent or risk to the infant is present.
