Brief psychotic disorder ⁠— according to the classifications of mental disorders DSM-IV-TR and DSM-5 ⁠— is a psychotic condition involving the sudden onset of at least one psychotic symptom (such as disorganized thought/speech, delusions, hallucinations, or grossly disorganized or catatonic behavior) lasting 1 day to 1 month, often accompanied by emotional turmoil. Remission of all symptoms is complete with patients returning to the previous level of functioning. It may follow a period of extreme stress including the loss of a loved one. Most patients with this condition under DSM-5 would be classified as having acute and transient psychotic disorders under ICD-10. Prior to DSM-IV, this condition was called "brief reactive psychosis." This condition may or may not be recurrent, and it should not be caused by another condition. The term bouffée délirante describes an acute non-affective and non-schizophrenic psychotic disorder, which is largely similar to DSM-III-R and DSM-IV brief psychotic and schizophreniform disorders. Presentation

BPD may occur in response to a significant stressor in ones life, or in other situations where a stressor is not apparent, including in the weeks following birth.In diagnosis, a careful distinction is considered for culturally appropriate behaviors, such as religious beliefs and activities.
