[Psychomotor performance of schizophrenic patients and long-term neuroleptic therapy]

15 patients diagnosed as schizophrenics (ICD 295) under long-term neuroleptic treatment were compared with 15 neurotic and normal persons concerning their ability at a psychomotor task. There was no difference between both groups; no correlation between performance and neuroleptic dosage was found. However, motoric coordination of a small group was impaired. The authors discuss several hypotheses referring to these findings.
