Brief psychotic disorder (BPD) is a mental health condition characterized by the presence of at least one psychotic symptom — such as delusions, hallucinations, incoherent speech, or behavioral disturbances — which lasts from one day to one month in duration and which is often accompanied by significant distress.
BPD is usually preceded by a significant stressor such as bereavement or childbirth.
The male to female ratio of BPD is 1:2, and the condition is more common in people with personality disorder. The onset of symptoms of BPD is usually in the late 30s and early 40s. The rates of BPD are higher in the developing world than in the developed world.
