To evaluate the relationship between sleep and sleepiness with memory complaints. Patients who were submitted to polysomnography between May and September of 2022 and answered the prospective and retrospective memory questionnaire and the Epworth sleepiness scale were included, respectively. Data were entered into an Excel spreadsheet and converted to a file compatible with the SPSS software. The sample consisted of 98 subjects, 62.2% male, mean age of 45.9 years, 73.4% overweight, 54.1% with comorbidities, and 51% with excessive sleepiness. There was a significant difference in sleep efficiency, respiratory disturbance index (RDI), slow wave sleep (SWS), and rapid eye movement (REM) sleep for the group with comorbidities; in latency to sleep and SWS between genders; and in RDI for the body mass index group. No correlation between RDI and memory could be identified, but there were statistically significant correlations between REM and sleep efficiency; RDI and REM sleep; RDI and SWS; SWS and sleep efficiency; and sleep efficiency and latency to sleep onset. Older adults performed better on memory tests when total sleep time (TST) is longer than 5 hours and excessive daytime sleepiness is related to complaints of prospective, retrospective, and total memory. Elderly people with TST longer than 5 hours have a better memory. Although a correlation between RDI and memory was not observed, a correlation between excessive daytime sleepiness-one of the main symptoms of patients with sleep disorders-and memory was.
评估睡眠及嗜睡与记忆障碍之间的关系。纳入了2022年5月至9月期间接受多导睡眠监测，并分别回答前瞻性和回顾性记忆问卷以及爱泼华嗜睡量表的患者。数据录入Excel电子表格，并转换为与SPSS软件兼容的文件。样本包括98名受试者，男性占62.2%，平均年龄45.9岁，73.4%超重，54.1%患有合并症，51%存在过度嗜睡。合并症组在睡眠效率、呼吸紊乱指数（RDI）、慢波睡眠（SWS）和快速眼动（REM）睡眠方面存在显著差异；性别之间在入睡潜伏期和慢波睡眠方面存在差异；体重指数组在呼吸紊乱指数方面存在差异。未发现呼吸紊乱指数与记忆之间存在相关性，但快速眼动睡眠与睡眠效率之间、呼吸紊乱指数与快速眼动睡眠之间、呼吸紊乱指数与慢波睡眠之间、慢波睡眠与睡眠效率之间以及睡眠效率与入睡潜伏期之间存在统计学显著相关性。当总睡眠时间（TST）超过5小时时，老年人在记忆测试中的表现更好，且白天过度嗜睡与前瞻性、回顾性和总体记忆障碍有关。总睡眠时间超过5小时的老年人记忆力更好。虽然未观察到呼吸紊乱指数与记忆之间的相关性，但睡眠障碍患者的主要症状之一白天过度嗜睡与记忆之间存在相关性。
