According to the National Institute of Mental Health, "Postpartum psychosis is a psychiatric emergency that requires hospitalization. Women experiencing symptoms of postpartum psychosis should seek immediate help by calling 911 or going to the nearest emergency room."¹ If you or someone close to you may have postpartum psychosis, call 911 or go to the nearest emergency room now.^{1, 2}

A 2017 systematic review found incidence between 0.89 and 2.6 per 1,000 women across five studies and did not pool them.³ NIMH also states, "Recovery is possible with professional help."¹

Symptoms of postpartum psychosis

NIMH lists delusions, hallucinations, mania, paranoia and confusion.¹ The MGH Center for Women's Mental Health describes the earliest signs as "restlessness, irritability, and insomnia", followed by a rapidly shifting depressed or elated mood, disorientation or confusion, and erratic or disorganized behavior. Delusional beliefs are common and often center on the infant.⁴

In a retrospective interview study of women with bipolar affective puerperal psychosis, 73% recalled an onset of symptoms by day 3. The most commonly recalled symptoms were feeling excited, elated or high (52%) and not needing to sleep or not being able to sleep (48%).⁵

When postpartum psychosis starts

MGH describes onset as early as the first 48 to 72 hours after delivery, with the majority of women developing symptoms within the first two postpartum weeks.⁴ In a prospective cohort of first-onset cases, the median onset was 8 days postpartum (interquartile range 5 to 14) and the median episode lasted 40 days (interquartile range 23 to 69).⁶ The NHS states that the most severe symptoms tend to last 2 to 12 weeks and that complete recovery can take 6 to 12 months or more.⁷

How common postpartum psychosis is

First-lifetime onset in register studies of psychiatric admissions varies from 0.25 to 0.6 per 1,000 births.⁸ One population-based study of first-time mothers found that 1.2 per 1,000 births were followed by hospitalization for psychosis within 90 days, and almost 50% of those women had no previous psychiatric hospitalization.⁹

The link with bipolar disorder

A 2026 expert consensus statement reports that in half of cases, first-onset postpartum psychosis is also the first onset of bipolar disorder.¹⁰

For women who already have bipolar disorder, a meta-analysis estimated severe postpartum episodes at 17% (95% CI 13-21).¹¹ Among parous women with bipolar disorder and no previous perinatal mood episode, 7% developed postpartum psychosis after a subsequent pregnancy.¹²

Will postpartum psychosis happen again?

Estimates vary with what was measured. In women with a history of postpartum psychosis, a meta-analysis estimated severe postpartum episodes at 29% (95% CI 20-41).¹¹ A 2016 review put relapse risk after a subsequent pregnancy at 31% (95% CI 22-42) in isolated postpartum psychosis.⁸ In a 2005 study of bipolar affective puerperal psychosis, 31 of 54 women who had further children (57%) had another puerperal psychotic episode, and the NHS describes "about a 1 in 2 chance".^{13, 7}

Preventive medication was associated with fewer relapses. Among women with bipolar disorder, postpartum relapse rates were 66% in those who were medication free during pregnancy and 23% in those who used prophylactic medication.¹¹ In a cohort of 70 high-risk women, none of the 20 women with a history of postpartum psychosis only who used postpartum prophylaxis relapsed, compared with 44.4% of those who declined it.¹⁴ These comparisons were not randomized. A prevention plan is made with the psychiatrist and obstetric team before delivery.

Treatment and the evidence behind it

One treatment cohort included 64 women consecutively admitted with postpartum psychosis and treated in sequence with benzodiazepines, antipsychotics, lithium and ECT. Remission occurred in 98.4% within the first three steps, and no patient required ECT. At 9 months postpartum, 79.7% were in sustained remission, and relapse was significantly less frequent in women treated with lithium than in those on antipsychotic monotherapy.¹⁵

That cohort had no control group. A search on November 12, 2026 found no randomized trial of treatment or prevention for postpartum psychosis.

Long-term outcome

In a meta-analysis of six studies and 645 patients followed for 11 to 26 years, 43.5% (95% CI 37.7% to 49.4%) had no later severe episodes outside the postpartum period.¹⁶ In a prospective cohort of 106 women, over two thirds had no major psychiatric episodes outside the postpartum period during follow-up, and none met criteria for schizophrenia or schizophreniform disorder.¹⁷

How it differs from postpartum depression and postpartum OCD

MedlinePlus sets postpartum psychosis apart from postpartum depression as something that develops very rarely and is "a medical emergency."²

Frightening thoughts about the baby also occur without psychosis. In one study, 57% of women with postpartum-onset major depression reported obsessional thoughts, and the most frequent content of their aggressive thoughts was causing harm to the infant.¹⁸ In a sample of 388 postpartum women, 44.4% reported unwanted intrusive thoughts of intentional infant-related harm, and they were not more likely to report aggression toward their newborn than women who did not report such thoughts.¹⁹

A 2006 review describes postpartum OCD as differentiated from postpartum psychosis "by the preservation of rational judgment and reality testing".²⁰ Postpartum Support International describes the intrusive images as "anxious in nature, not a break from reality."²¹ Telling the two apart is a clinician's assessment. A 2018 clinical guide states that when postpartum psychosis is suspected, "the patient must have a psychiatric evaluation as soon as possible (in the emergency room if necessary)."²³

Risk to mother and infant

MGH states that the risk for infanticide, as well as suicide, is significant in this population.⁴ A 2017 review found that death by suicide is rare during the acute episode and that the rate is high later in the mother's life.²²

The same review traces a 4% filicide figure in recent American papers to a misreading of a 1985 Scottish study. Its own count from the case literature was 4.5% (24 of 535) in depressive psychoses and less than 1% (9 of 1,115) in early-onset psychoses without overt depression, a count that includes accidental cases.²² A search on November 12, 2026 found no population-based rate.

Limitations of the evidence

This evidence has limitations. First, the treatment and prevention findings are observational. Second, the incidence studies defined and assessed cases differently, and a search on November 12, 2026 found no US incidence figure. Nevertheless, the sources agree that onset is early, usually within the first two weeks, and that most women in the treatment cohort reached remission.

For a woman with bipolar disorder or a previous postpartum psychosis, the plan is made with her psychiatrist before delivery, and new confusion, delusions, hallucinations or sleeplessness with elevated mood after a birth is treated as an emergency.

Frequently asked questions

Is postpartum psychosis an emergency?

Yes. NIMH states that postpartum psychosis is a psychiatric emergency that requires hospitalization and that women experiencing symptoms should seek immediate help by calling 911 or going to the nearest emergency room.^{1, 2}

How common is postpartum psychosis?

A 2017 systematic review found incidence between 0.89 and 2.6 per 1,000 women across five studies and did not pool them. First-lifetime onset in register studies varies from 0.25 to 0.6 per 1,000 births.^{3, 8}

When does postpartum psychosis start?

The majority of women develop symptoms within the first two postpartum weeks, and onset can be as early as the first 48 to 72 hours after delivery. In one prospective cohort the median onset was 8 days postpartum.^{4, 6}

Will postpartum psychosis happen again with another baby?

Estimates vary with what was measured: 29% for severe postpartum episodes in women with a history of postpartum psychosis, 31% for relapse after a subsequent pregnancy in isolated postpartum psychosis, and 57% for another puerperal psychotic episode in a 2005 study of bipolar affective puerperal psychosis. The NHS describes about a 1 in 2 chance. A prevention plan is made with the psychiatrist and obstetric team before delivery.^{11, 8, 13, 7}

Are scary thoughts about hurting my baby a sign of postpartum psychosis?

Unwanted intrusive thoughts are common without psychosis: in a sample of 388 postpartum women, 44.4% reported unwanted intrusive thoughts of intentional infant-related harm, and they were not more likely to report aggression toward their newborn than women who did not report such thoughts. Telling these apart from psychosis is a clinician's assessment, and a 2018 clinical guide states that suspected postpartum psychosis needs a psychiatric evaluation as soon as possible, in the emergency room if necessary.^{19, 23}

In a crisis: call or text 988, or go to the nearest emergency department. A first episode of psychosis belongs in a hospital-based or coordinated specialty care program.
