Postpartum Psychosis Is a Medical Emergency. One in a Thousand Mothers Experiences It. Every Family Should Know the Signs.

Postpartum psychosis affects approximately one to two women per 1,000 births. It is the most severe form of perinatal mental illness and is a psychiatric emergency — one that requires immediate hospital admission and treatment. Unlike postpartum depression and anxiety, which typically develop gradually over days to weeks, postpartum psychosis begins suddenly, most often within the first two weeks after birth and frequently within the first three days, and can escalate from initial symptoms to full psychosis within hours.

Every family who has had a baby should know the signs of postpartum psychosis — because in an acute episode, the mother herself may not be able to recognise that something is wrong.

The signs — what to watch for and why they are easy to miss

The signs of postpartum psychosis can be missed or dismissed in the early stages because some of them superficially resemble ordinary postpartum experiences. The signs include: rapid and extreme mood swings that go far beyond normal postpartum emotional variability; grandiosity or unusual elation — importantly, postpartum psychosis does not always look like sadness, and a new mother who seems unusually, inexplicably euphoric, talking very rapidly, not needing sleep, and making very little sense may be in the early stages; confusion or disorientation that cannot be explained by sleep deprivation alone; paranoid beliefs — that the baby or mother is in danger, that people are trying to harm them; hallucinations, hearing or seeing things that are not there; severely disrupted or absent sleep despite opportunities to rest; and disorganised, incoherent speech or behaviour.

Who is at risk — and why advance planning matters

Risk factors for postpartum psychosis include: personal or family history of bipolar disorder — this is the strongest risk factor, with approximately 25% of women with bipolar disorder developing postpartum psychosis after a birth; previous episode of postpartum psychosis, which carries approximately a 50% recurrence risk in subsequent pregnancies; and first-time motherhood.

Women with a known diagnosis of bipolar disorder should have a specific perinatal mental health care plan created during pregnancy, before delivery, outlining the monitoring plan, early warning signs to watch for, and the emergency action plan. This is not catastrophising. It is preparation that can save a life.

What to do if you suspect postpartum psychosis

If you are a family member who suspects that a new mother may have postpartum psychosis, do not wait and do not go to a general emergency service if a psychiatric emergency service is available. Take her to the nearest hospital emergency department immediately and use the specific words 'postpartum psychosis' — this communicates the nature of the emergency and the need for psychiatric assessment rather than general medical assessment. Do not leave her alone with the baby until she has been assessed.

With appropriate treatment — which typically includes mood stabilisers and antipsychotic medications, and in some cases electroconvulsive therapy — the vast majority of women with postpartum psychosis make a full recovery. The condition is serious. It is also treatable. Speed of response is the critical variable.
