Longitudinal study of the course and outcome of first-episode psychosis

Abstract

BackgroundStudy of first episode psychosis (FEP), an episode of psychotic nature, which manifests for the first time in an individual in the longitudinal continuum of his/her illness, has been a matter of research interest in recent years, as this may give more insight to the overall phenomenology and course of psychotic illnesses. MethodsA study was undertaken to evaluate course and outcome of first episode psychosis. A total of 100 consecutive inpatients were selected for the study. Informed consent was obtained. Structured Proforma was used for recording psychosocial profiles and relevant medical history. Brief Psychiatric Rating Scale (BPRS) was given to assess the severity of psychopathology; Positive and Negative Symptom Scale (PANSS) to assess the severity of psychosis; Becks Suicidal Ideation Scale (BSI) to assess the extent of suicidality and Global Assessment of Functioning (GAF) to assess global functioning of the individual. The assessment was done at baseline, at six months, and at one year. ResultsFirst episode psychosis constituted around a tenth of the caseload. It commonly affected people in the third decade of life. There was an improvement in 92% of the cases over a year of study. Schizophrenia constituted the majority of first episode psychosis. The history of smoking was relatively higher in acute and transient psychotic disorders. Age inversely correlated with the severity of psychopathology. There was no difference in improvement in psychopathology over time in patients of schizophrenia and related disorder vis--vis other psychotic disorders. ConclusionOur study did not find any significantly varied sociodemographic factors in the course and outcome of the illness. It also refuted the schism between various types of psychosis based on the current classificatory system. It draws our attention toward the unitary concept of psychosis and is a call to re-think our strategies in the management of psychosis.
