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。
Objective: To investigate the relationship between memory loss and REM sleep in patients with cerebral infarction. METHODS: Memory measurements and polysomnography were performed in 40 patients with cerebral infarction. Traces were recorded overnight and the sleep parameters were analyzed and compared with 22 normal controls. Results: Patients with cerebral infarction had longer sleep latency, more awake times, less total sleep time, lower sleep efficiency, decreased REM duration, decreased REM activity and density (P <001), and decreased memory loss correlated with REM reduction (R = 068, P <001). Conclusion: Patients with cerebral infarction not only reduce the amount of sleep and sleep quality changes, especially the reduction of REM sleep and memory are closely related.
