Patients with acute onset, non-organic psychotic states are frequently reported from India and certain other developing countries. This paper relates to an investigation of such cases in terms of their clinical history and their symptomatology examining the extent to which these are similar /dissimilar to schizophrenia and affective psychosis. 109 cases of acute psychosis fulfilling specified screening criteria were assessed on the Schedule for Clinical Assessment Acute Psychotic States (SCAAPS) and Present Slate Examination (PSE). Vie findings revealed that about 34% of all patients experienced significant strees before the onset of psychosis. About 40% of all cases presented with Catego subtype which was not indicative clearly of a specific diagnostic category. This subgroup of patients differed from the remaining 60% of patient in having greater frequency of stress before the onset of psychosis. On the whole the delusions were more commonly seen in patients from upper socioeconomic status & urban background. Limitations of classificatory provisions in the ICD-9 and catego in dealing with acute psychotic state are highlighted.
