Abstract：
:The validity of previously hypothesized predictors of elapse following neuroleptic discontinuation was examined. One hundred sixty-two outpatients, with either Research Diagnostic Criteria schizophrenia or schizoaffective disorder, were discontinued from neuroleptic medication for a 28-day period or until judged to be relapsed. Pre-discontinuation neuroleptic dosage level, the severity of psychotic symptoms, and the presence of dyskinetic movements prior to neuroleptic discontinuation were the predictor variables. Of the 162 patients, 62.7% did not relapse during the study period. There were no differences in the survival rates between the patients withdrawn from oral versus depot neuroleptics. Neuroleptic dosage, but not severity of psychotic symptoms or dyskinetic movements, predicted relapse. These results support the hypothesis that pre-withdrawal neuroleptic dosage level predicts relapse, but fail to validate either severity of psychotic symptoms or presence of dyskinetic movements as predictors of relapse.
