Such psychosis (when diagnosed as such), is often considered "premenstrual exacerbation" or "menstrual psychosis", or postpartum psychosis. Childbirth may trigger the disorder in some women. Approximately 1 in 10,000 women experience brief psychotic disorder shortly after childbirth. Diagnosis
The symptoms must not be caused by schizophrenia, schizoaffective disorder, delusional disorder, or mania in bipolar disorder. They must also not be caused by a drug (such as amphetamines) or medical condition (such as a brain tumor). Differential diagnosis
There are general medical causes of brief psychosis that should be considered during evaluation, including postnatal depression, HIV and AIDS, malaria, syphilis, Alzheimers disease, Parkinsons disease, hypoglycaemia (an abnormally low level of glucose in the blood), lupus, multiple sclerosis, brain tumor, SARS-CoV-2 (COVID-19) infection and pediatric autoimmune neuropsychiatric disorders (PANS). Epidemiology
The exact incidence and prevalence of brief psychotic disorder is not known, but it is generally considered uncommon. Internationally, it occurs twice as often in women than men, and even more often in women in the United States. It typically occurs in the late 30s and early 40s. Approximately 1 in 10,000 women experience brief psychotic disorder shortly after childbirth. History
Otto Fenichel noted how such short psychotic breaks were more common in World War II than in World War I, in the wake of traumatic shocks: he considered in such cases that "enough preconscious attention remains to re-establish the contact with reality as soon as it becomes bearable again".
