We examined whether neuropsychiatric symptoms (NPS) interact with cerebrospinal fluid (CSF) biomarkers (amyloid-β42 [Aβ42], tau, phosphorylated tau181 [ptau181], tau/Aβ42, and ptau181/Aβ42) of Alzheimer's disease pathology to predict driving decline among cognitively-normal older adults (N = 116) aged ≥65. Cox proportional hazards models examined time to receiving a rating of marginal or fail on the driving test. Age, education, and gender were adjusted in the models. Participants with more abnormal CSF (Aβ42, tau/Aβ42, ptau181/Aβ42) and NPS were faster to receive a marginal/fail on the road test compared to those without NPS. NPS interact with abnormal CSF biomarkers to impact driving performance among cognitively-normal older adults.
我们研究了神经精神症状(NPS)是否与阿尔茨海默病病理的脑脊液(CSF)生物标志物(淀粉样蛋白β42 [Aβ42]、tau、磷酸化tau181 [ptau181]、tau/Aβ42和ptau181/Aβ42)相互作用,以预测65岁及以上认知正常的老年人(N = 116)的驾驶能力下降情况。Cox比例风险模型检验了在驾驶测试中获得边缘评分或不及格评分的时间。模型中对年龄、教育程度和性别进行了调整。与没有NPS的参与者相比,脑脊液(Aβ42、tau/Aβ42、ptau181/Aβ42)异常且有NPS的参与者在路考中更快获得边缘/不及格评分。NPS与异常的脑脊液生物标志物相互作用,影响认知正常的老年人的驾驶性能。
