title: Can chronic neuroleptic treatment promote sleep disturbances in elderly schizophrenic patients?
abstract: It has been proposed that sleep disturbances, especially reduced delta sleep, are related to a poor outcome in schizophrenia. To determine whether long-term treatment with neuroleptics can promote sleep disturbances by increasing the risk of a nocturnal myoclonus syndrome (NMS) (=periodic movements in sleep) related insomnia, we performed all-night polysomnography in 10 chronically ill schizophrenic patients who had been under neuroleptic therapy for a mean of 27 years. NMS-related insomnia was detected in all 10 patients. Potential pathophysiological relationships between long-term neuroleptic therapy and NMS occurrence are discussed. Our findings suggest that long-term administration of neuroleptics favours the appearance of insomnia.
