Psychotic states with acute onset and short duration have long been recognized as clinical entities, and several researchers have attempted to classify them under terms such as cycloid psychosis, bouffee delirante, and reactive psychosis. However, descriptive and predictive validities of the diagnostic categories have not been fully established. In the last decade, there has been a renewed interest in studying these groups of psychoses. It is reflected in the tenth revision of the International Classification of Diseases and Related Health Problems (ICD-10) that has introduced a group entitled 'acute and transient psychotic disorder' (ATPD). Susser and Wanderling in 1994 introduced a group of non-affective psychoses that are characterized by very acute onset and full remission under the rubric of 'Non affective Acute Remitting Psychosis' (NARP). Studies have suggested that acute brief psychoses, may exhibit distinctive biological associates, temporal stability, duration criterion, and excellent long term course and outcome, especially in developing countries.
