Background One of the most prevalent sleep disorders is obstructive sleep apnea (OSA). Patients with OSA have increased risk of car and work place accidents which may be attributed to cognitive impairment due to poor sleep quality. Thus, there is an increasing need to implement simple, reliable and rapid screening for cognitive impairment in OSA patients. Objectives To assess auditory event-related potentials (ERPs) and quantitative electroencephalography (QEEG) as screening tools for detection of cognitive impairment in OSA patients taking circadian effects into consideration. Subjects and methods Twenty OSA patients as well as 20 gender- and age-matched volunteers were subjected to trail making test (TMT), auditory ERPs and QEEG before and after at least 6 h polysomnographic recording. Correlating electrophysiological tools with TMT and clinical parameters was done as well Results Statistically significant changes in P300 latency and reaction time, in addition to occipital alpha power were noted in cases; however, TMT failed to detect such changes. Electrophysiological results were not constantly correlated to clinical parameters. Conclusion Auditory ERPs and QEEG before and after polysomnography can be of benefit as cognitive screening test for suspected cognitive impairment in OSA patients.

电生理检查能否用作检测阻塞性睡眠呼吸暂停低通气综合征认知障碍的筛查工具?

背景 阻塞性睡眠呼吸暂停 (OSA) 是最普遍的睡眠障碍之一。OSA 患者发生汽车和工作场所事故的风险增加,这可能是由于睡眠质量差导致的认知障碍。因此,越来越需要对 OSA 患者的认知障碍实施简单、可靠和快速的筛查。目的 评估听觉事件相关电位 (ERP) 和定量脑电图 (QEEG) 作为检测 OSA 患者认知障碍的筛查工具,同时考虑昼夜节律效应。受试者和方法 在至少 6 小时多导睡眠图记录之前和之后,20 名 OSA 患者以及 20 名性别和年龄匹配的志愿者接受了跟踪测试 (TMT)、听觉 ERP 和 QEEG。还完成了将电生理工具与 TMT 和临床参数相关联的工作 结果 除了枕骨 α 功率之外,还注意到 P300 潜伏期和反应时间的统计学显着变化;然而,TMT 未能检测到此类变化。电生理结果并不总是与临床参数相关。结论 多导睡眠监测前后的听觉 ERPs 和 QEEG 可作为 OSA 患者疑似认知障碍的认知筛查试验。
