New Delhi, Sept. 19 -- The recent trial of Lindsay Clancy, the American mother accused of killing her three children, has brought an unsettling psychiatric condition into the public conversation: postpartum psychosis.
Her defence argued that she was experiencing postpartum psychosis at the time of the deaths when the heinous crimes were carried out by her. The trial ended in a mistrial in September 2026 after the jury could not reach a unanimous verdict.
What is postpartum psychosis?
Postpartum psychosis is rare, but it is one of the most serious psychiatric emergencies associated with childbirth. Unlike the relatively common "baby blues" or next in time, postpartum depression; psychosis involves a loss of contact with reality. Postpartum psychosis is characterised by a sudden loss of contact with reality. A woman may develop hallucinations, delusions, severe confusion, extreme agitation, mania, profound mood changes or rapidly fluctuating behaviour. It often begins suddenly, frequently within the first few weeks after childbirth.
Why does it happen? The causes are not completely understood. Hormonal changes, sleep deprivation, biological vulnerability and underlying illnesses such as bipolar disorder can all contribute. A previous episode of postpartum psychosis or a history of bipolar disorder substantially increases risk.
Most importantly, postpartum psychosis does not automatically mean a mother will become violent, but there are higher chances. Because impaired reality testing can sometimes produce dangerous behaviour, it must be treated as an emergency.
What should happen to the mother and baby?
The first priority is safety. A woman suspected of having postpartum psychosis needs urgent psychiatric assessment and usually hospital admission. If possible, a specialised mother and baby unit allows the mother to receive intensive treatment while remaining with her infant, with appropriate supervision.
The two must be separated if the mother is acutely confused, suicidal, aggressive or unable to safely care for the baby, the infant may need to be cared for temporarily by another trusted adult or the appropriate hospital team.
How is it treated?
Treatment usually involves antipsychotic medication, restoration of sleep and, depending on the clinical picture, mood stabilisers such as lithium. Breastfeeding decisions require individual assessment of medication risks and benefits.
ECT, or electroconvulsive therapy, is another important option. It can produce rapid improvement and may be particularly useful when symptoms are severe, treatment-resistant, accompanied by catatonia, severe depression or significant suicidal risk.
What happens when a crime is committed?
This is where psychiatry and law intersect as a part of Forensic psychiatry.
A diagnosis of postpartum psychosis does not automatically make someone legally insane. The legal question is what the person's mental state was at the time of the offence, and whether the illness impaired the specific capacities recognised by law.
In India, the relevant provision is Section 22 of the Bharatiya Nyaya Sanhita, 2023, corresponding to the former Section 84 of the Indian Penal Code. It concerns acts committed by a person of unsound mind who, because of that mental state, was incapable of understanding the nature of the act or that it was wrong or contrary to law.
This is why forensic psychiatric assessment matters. The psychiatrist is not deciding whether someone is "good" or "bad", guilty or innocent. The task is to reconstruct the person's mental state at the time of the alleged offence and provide an expert opinion to the court.
Postpartum psychosis is not synonymous with violence, and a diagnosis is not a legal defence by itself. But when psychosis occurs, recognising it early can protect both mother and baby and, in rare cases, become crucial to understanding criminal responsibility.
Postnatal mother care is still a growing field in our country and needs more awareness.
