Summary This article examines the clinical, epidemiological and nosological aspects of short-lived psychotic disorders as currently classified under ‘acute and transient psychotic disorders' in ICD-10 and ‘brief psychotic disorder’ in DSM-5. After describing earlier diagnostic concepts such as bouffée délirante , cycloid psychosis, reactive psychosis and schizophreniform psychosis, we present an overview of the literature and discuss implications for classification, diagnosis and treatment of these conditions, pointing out differences from longer-lasting psychotic disorders.
