Acute non-organic psychosis-outcome after 10 years.

62 out of 68 acute psychosis patients who were initially recruited from the Bikaner Centre in 1982 for the Indian Council of Medical Research (ICMR) study on "phenomenology and natural history of acute psychosis" were assessed after completion of 10 years in 1992-93 on SCAAPS and PSE with the objective of studying the long term course and outcome of acute psychosis. The results show that 35 (56.45%) patients of acute brief episode of psychosis never had any psychotic illness during the course of follow-up. Remission was significantly better in the young, the unmarried, in those who belonged to the Hindu religion and in those who developed the full blown psychosis abruptly within 48 hours. Other sociodemographic, personal history variables, and symptomatology could not distinguish this remitted group from the rest of the patients.
