Acute psychosis, although not recognized as a diagnostic term in DSM-5 is commonly used to describe a rapid deterioration of behavior associated with hallucinations and delusions. Schizophreniform disorder, brief psychotic disorder, and organic psychoses fall under this rubric. The DSM-5 diagnosis of schizophreniform disorder depends on the persistence of schizophrenia-like symptoms for at least 1 month and exclusion of other causes of acute psychosis. Brief psychotic disorder (often referred to as brief reactive psychosis) lasts less than 1 month, but more than 1 day. It is typically regarded as a reaction to marked stress in persons with borderline or antisocial personality disorders.
