越来越多的证据表明睡眠时间与阿尔茨海默病(AD)之间存在关联,但尚不清楚睡眠时间是否是AD疾病过程的表现。我们研究了AD的遗传易感性是否使用AD的遗传风险评分(GRS)预测睡眠时间(AD-GRS),在406,536名具有欧洲血统且在登记时没有痴呆症的英国生物库参与者中。较高的AD-GRS评分与较短的睡眠时间相关(B =-0.014,95%置信区间[CI] =-0.022至-0.006),尤其是在55岁以上的人群中。使用AD-GRS作为AD诊断的工具变量,早期AD使睡眠持续时间减少1.87小时(95%CI = 0.96,2.78)。睡眠时间短可能是AD的早期标志。
Growing evidence has suggested an association between sleep duration and Alzheimer’s disease (AD), but it is unclear if sleep duration is a manifestation of the AD disease process. We studied whether genetic liability for AD predicts sleep duration using a genetic risk score (GRS) for AD (AD-GRS), in 406,536 UK Biobank participants with European ancestry and without dementia at enrollment. Higher AD-GRS score was associated with shorter sleep (b = −0.014, 95% confidence interval [CI] = −0.022 to −0.006), especially in those aged 55+. Using AD-GRS as an instrumental variable for AD diagnosis, incipient AD reduced sleep duration by 1.87 hours (95% CI = 0.96, 2.78). Short sleep duration might be an early marker of AD.
