Background:Sleep disorders are widespread among patients with schizophrenia and contribute to adverse clinical outcomes. Antipsychotic drugs exert varying effects on sleep, and the effects of atypical agents may differ from those of conventional neuroleptics.Objective:To review the literature on the effects of atypical medication on subjective and objective sleep quality in patients with schizophrenia.Methods:A non-systematic literature review of Medline was performed in August 2003 searching the period from January 1985 to August 2003 for studies of the effects of atypical antipsychotics on sleep.Results:We found published studies of clozapine, olanzapine, and risperidone, but none on quetiapine or ziprasidone. Studies with clozapine showed that it increased total sleep time, sleep efficiency, stage-2 non-rapid eye movement sleep and rapid eye movement (REM) sleep density, and decreased stage-4 sleep, slow wave sleep (SWS) and stage-1 sleep. Single-dose studies with olanzapine have shown that it increases SWS, sleep continuity, total sleeping time, subjective sleep quality, and delta sleep. Long-term studies with risperidone have shown improvements in total sleep, sleep efficiency, sleep continuity, SWS, and stage-2 sleep, and reductions in sleep latency, number of awakenings, and proportion of time awake. These benefits were paralleled by improvements in subjective sleep assessment and psychopathology, and psychosocial functioning.Conclusions:The evidence presented in this review suggests that atypical antipsychotics exert favorable effects on sleep profile compared with conventional agents, including improvement of subjective sleep quality and modification of specific sleep stages known to be associated with better clinical outcome.

Slow-wave sleep (SWS) and rapid-eye-movement sleep (REM) were recorded in cats for 32 h a) under control conditions, b) following intraventricular infusions of artificial cerebrospinal fluid (CSF), and c) following infusions of sleep-promoting factor S prepared from human urine (SPU). During the first 12 h after receiving artificial CSF, the cats slept 4.9 +/- 0.2 h in slow-wave sleep (SWS) and 1.4 +/- 0.1 h in REM. Similar values were obtained from the same cats under control conditions. After infusions of SPU, the duration of SWS in the same cats increased to an average of 6.9 +/- 0.5 h with no significant change in REM averaged over 12 h; a transient decrease of REM in the first 4 h was fully compensated in subsequent hours. The increased SWS induced by the sleep-promoting factor from human urine subsided after 12 h, and there was no compensatory increase in wakefulness during the subsequent 20 h. The normal sleep cycle was not affected. In cats, therefore, the primary effect of SPU is to increase normal SWS, with little effect on REM.

Transcranial Alternating Current Stimulation

Background: Poor sleep quality is a common complaint, affecting over one third of people in the United States. While sleep quality is thought to be related to slow-wave sleep (SWS), there has been little investigation to address whether modulating slow-wave oscillations (SWOs) that characterize SWS could impact sleep quality. Here we examined whether closed-loop transcranial alternating current stimulation (CL-tACS) applied during sleep impacts sleep quality and efficiency. Methods: CL-tACS was used in 21 participants delivered at the same frequency and in phase with endogenous SWOs during sleep. Sleep quality was assessed in the morning following either verum or sham control stimulation during sleep, with order counterbalanced within participants. Results: Higher sleep quality and efficiency were found after verum stimulation nights compared to control. The largest effects on sleep quality were found immediately following an adaptation night in the laboratory for which sleep quality was reduced. Conclusions: Applying CL-tACS at the same frequency and phase as endogenous SWOs may offer a novel method to improve subjective sleep quality after a night with poor quality sleep. CL-tACS might be helpful for increasing sleep quality and efficiency in otherwise healthy people, and in patients with clinical disorders that involve sleep deficits.
