摘要
目的:探讨脑梗死患者记忆减退与快速眼动(REM)睡眠的关系。方法:对40例脑梗死患者进行记忆测定和多导睡眠图通宵描记,分析有关睡眠参数并与22名正常人比较。结果:脑梗死患者睡眠潜伏期长,醒转次数增多,总睡眠时间减少,睡眠效率低,REM时间减少,REM活动度和密度均降低(P<001),其记忆减退与REM减少具有相关性(r=068,P<001)。结论:脑梗死患者不但有睡眠量的减少而且有睡眠质的改变,尤其REM睡眠减少与记忆减退有密切关系。
Objectives: To explore the relation between hypomnesis of patients with cerebral infarction and rapid eye movement (REM) sleep.Methods: Polysomnography and memory test were performed in 40 patients with cerebral infarction and 22 normal subjects were served as controls. The parameters of sleep were analysed.Results: The sleep latency was prolonged, the frequency of wakening increased, the total sleeping time decreased, the sleeping efficiency reduced and REM sleep density and activity decreased as compared with the controls. A correlation was noted between hypomsesis and a decrease in REM sleep ( r =0.68, P <0.01). Conclusions: A decrease in sleeping amount as well as a change of sleeping quality was noted in patients with cerebral infarction, and there might be a close relation between a decrease in REM sleep and hypomnesis.
