摘要
运用多导睡眠描记对12例青壮年和8例中老年慢性失眠症患者的睡眠状况进行了研究,并与同年龄组正常人进行比较,发现两个年龄组失眠症患者的慢波睡眠(SWS)、快波睡眠(PS)和总睡眠时间(TST)均减少,其中以深睡(S_3+S_4)减少尤为明显。觉醒次数(Wn)和觉醒持续时间(Wt)均增加,睡眠潜伏期(Lsws)延长,睡眠效率降低。提示慢性失眠症患者不仅睡眠量减少,而且睡眠质量也明显降低。
Polysomnography of two groups of chronic insomnia with age ranging from 20 to 40 years and above 40 years were analyzed and compared with corresponding normal groups. In both insomnia groups, slow wave sleep, paradoxical sleep, total sleep time and the sleep effcificy especially the deeper sleep (S_3+S_4) decreased, the number of arousals and the total time of wake after sleep onset increased, and the sleep latency prolonged. These results suggest that chronic insomnia not only decrease the time of sleep, but also the quality of sleep.
