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.

AbstractOur thoughts alter our sleep, but the underlying mechanisms are still unknown. We propose that mental processes are active to a greater or lesser extent during sleep and that this degree of activation affects our sleep depth. We examined this notion by activating the concept of “relaxation” during sleep using relaxation-related words in 50 healthy participants. In support of our hypothesis, playing relaxing words during non-rapid eye movement sleep extended the time spent in slow-wave sleep, increased power in the slow-wave activity band after the word cue, and abolished an asymmetrical sleep depth during the word presentation period. On the subjective level, participants reported a higher sleep quality and elevated alertness ratings. Our results support the notion that the activation of mental concepts during sleep can influence sleep depth and provide a basis for interventions using targeted activations to promote sleep depth and sleep quality to foster well-being and health.

Abstract Introduction Cognitive processes (e.g., rumination, perception of an unfamiliar sleeping environment, relaxation techniques) alter our sleep, but the underlying mechanisms are still unknown. Theories of embodied or grounded cognition assume that semantic meaning is stored in multimodal neuronal networks. We therefore assume that cognitive concepts are closely linked to related bodily functions. We propose that mental processes are active to a greater or lesser extent during sleep and that this degree of activation affects our sleep depth. Methods We examined this notion by activating the concept of “relaxation” during sleep using relaxation-related words in 50 healthy participants. After an adaption night, subjects slept in the sleep laboratory for two experimental nights according to a within-subject cross-over design. During one experimental night, relaxing words (e.g., “sea”, “relax”) were presented to promote sleep depth. During the other experimental night, control words were presented (e.g., “produce”, “materials”). As the amount of SWS peaks within the first sleep cycle, words were presented during NREM sleep starting with the second sleep cycle (at the latest 120 min after sleep onset). In addition, a mood and a subjective sleep quality questionnaire was conducted. Results In support of our hypothesis, playing relaxing words during non-rapid eye movement sleep extended the time spent in slow-wave sleep during the period, when words were presented. Furthermore, power in the slow-wave activity band was increased several seconds after the cue for relaxing compared with control words. The increased sleep depth by means of relaxing words was accompanied by a reduced interhemispheric asymmetry of SWA and slow-wave density in the during-cueing period. The changes observed in objective sleep translated to the subjective level with an increase in subjective sleep quality and alertness ratings. Conclusion The present study showed that the semantic meaning of words presented during NREM sleep is capable of affecting sleep physiology, SWS maintenance and the subjective evaluation of sleep quality. Our results support the notion that the activation of mental concepts during sleep can influence sleep depth and provide a basis for interventions using targeted activations to promote sleep depth and sleep quality to foster well-being and health.

Hypnotic Suggestions

AbstractSlow-wave sleep (SWS) is fundamental for maintaining our health and well-being, and SWS is typically reduced in stress-related sleep disturbances and age-related sleep disorders. We have previously reported that exposure to hypnotic suggestions before sleep effectively increases the duration of SWS during a midday nap in younger and older women suggestible for hypnosis.However, it remains unclear whether this beneficial effect of hypnosis on SWS can be generalized to night-time sleep and men. Therefore, we tested the effect of the hypnotic suggestions on SWS across an 8 hours night-time sleeping interval in 43 healthy young French-speaking subjects (19 males) of high and low suggestibility. In accordance with our previous results, listening to hypnotic suggestions before sleep increased the amount of SWS in highly suggestible subjects significantly by 13 min compared to a control condition in both genders. Particularly in the first hour, slow-wave activity was significantly increased after hypnosis as compared to the control night in high suggestible. The hypnosis-induced benefits on objective sleep parameters were also reflected in increased subjective sleep quality ratings. Our results demonstrate that hypnotic suggestions are an effective tool to deepen sleep and improve sleep quality also across a whole night of sleep in young healthy men and women. Our findings provide an important basis for the examination and potential application of hypnosis to improve deep sleep in populations with sleep disturbances.

Subjective Sleep

IntroductionEarlier studies reported that subjective sleep quality correlates with objective polysomnographically measured sleep initiation and continuity, but less with sleep architecture.AimsThis study aimed to investigate relations between subjective and objective sleep in normals (N), insomnia comorbid with generalized anxiety disorder (G) and apnea (A).MethodsOne hundred and seventy-seven normals (50.9±19.6a), 100 insomniac G patients (37.9±10.6a) and 51 A patients (51.3±9.7a) completed the self-rating scale for sleep and awakening quality (Saletu et al. 1997) regarding two polysomnographic nights analyzed by the Somnolyzer (Anderer et al. 2005). Correlations were calculated based on changes between the first (adaptation) and second polysomnographic night to diminish inter-individual variances of sleep perception.ResultsIn N, subjective sleep quality (S-QUA) demonstrated correlations (p < 0.01) with sleep efficiency (EFF), wake after sleep onset (WASO), S2, S1%, REM, S1, frequency of awakenings (FW), latency to continuous sleep (L-CONT), sleep latency (S-LAT) and slow-wave sleep, while awakening quality (A-QUA) showed weak (p < 0.05) correlations with EFF and WASO. Somatic complaints (S-COM) correlated (p < 0.05) with WASO and REM. In G, correlations (p < 0.01) were obtained between S-QUA and EFF, WASO, S2, L-CONT and S-LAT (p < 0.05), while A-QUA correlated with S2, WASO and EFF. In A, S-QUA correlated (p < 0.01) with EFF, S2, S1%, S2%, L-CONT, WASO and less (p < 0.05) with S-LAT and S1. A-QUA correlated with S2, S2% (p < 0.01), L-CONT and EFF (p < 0.05). S-COM correlated with S-CONT (p < 0.01) and S-LAT (p < 0.05).ConclusionEFF, WASO, S2 and less S-LAT determine good S-QUA in all groups.

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.

The Relationship

Objectives: the current study aimed to investigate the relationship between physical activity (PA) level and inhibitory control performance and then to determine whether this association was mediated by multiple sleep parameters (i.e., subjective sleep quality, sleep duration, sleep efficiency, and sleep disturbance). Methods: 180 healthy university students (age: 20.15 ± 1.92 years) from the East China Normal University were recruited for the present study. PA level, sleep parameters, and inhibitory control performance were assessed using the International Physical Activity Questionnaire (IPAQ), the Pittsburgh Sleep Quality Index Scale (PSQI), and a Stroop test, respectively. The data were analyzed using structural equation modeling. Results: A higher level of PA was linked to better cognitive performance. Furthermore, higher subjective sleep quality and sleep efficiency were associated with better inhibitory control performance. The mediation analysis revealed that subjective sleep quality and sleep efficiency mediated the relationship between PA level and inhibitory control performance. Conclusion: our results are in accordance with the literature and buttress the idea that a healthy lifestyle that involves a relatively high level of regular PA and adequate sleep patterns is beneficial for cognition (e.g., inhibitory control performance). Furthermore, our study adds to the literature that sleep quality and sleep efficiency mediates the relationship between PA and inhibitory control performance, expanding our knowledge in the field of exercise cognition.
