Long term functioning in early onset psychosis: two years prospective follow-up study.

Background: There were few studies on the outcome of schizophrenia in developing countries. Whether the outcome is similar to or different from developed world is still a point for research. The main aim of the current study was to know if patients with early onset non affective psychosis can behave and function properly after few years from start of the illness or not. Other aims included investigation of possible predictors and associated factors with remission and outcome.

Method: The study prospectively investigated a group of 56 patients with onset of psychosis during childhood or adolescence. Diagnosis made according to DSM-IV criteria and included; schizophrenia, psychotic disorder not otherwise specified and acute psychosis. Severity of psychosis was measured by PANSS. Measures of the outcome included; remission criteria of Andreasen et al 2005, the children's global assessment scale and educational level.

Results: Analysis of data was done for only 37 patients. Thirty patients diagnosed as schizophrenia and 7 with Psychotic disorder not otherwise specified. Mean duration of follow up was 38.4 +/- 16.9 months. At the end of the study, 6 patients (16.2%) had one episode, 23 (62.1%) had multiple episodes and 8 (21.6%) continuous course. Nineteen patients (51.4%) achieved full remission, and only 11 (29.7%) achieved their average educational level for their age. Twenty seven percent of the sample had good outcome and 24.3% had poor outcome. Factors associated with non remission and poor outcome included gradual onset, low IQ, poor premorbid adjustment, negative symptoms at onset of the illness and poor adherence to drugs. Moreover, there was tendency of negative symptoms at illness start to predict poor outcome.

Conclusion: Some patients with early onset non affective psychosis can behave and function properly after few years from the start of the illness. Although remission is a difficult target in childhood psychosis, it is still achievable.
