JAMA Neurol:老年人白天过度嗜睡与Aβ积累相关

2018-03-14 zhangfan MedSci原创

对于无痴呆症状的老年人群,白天睡眠过多与区域性Aβ-淀粉样蛋白积累相关,白天睡眠过多是阿尔茨海默有关的病理变化的表象之一

年龄是白天睡眠过多(EDS)的相关因素,研究发现EDS与老年人认知衰退相关。近日研究人员考察了非痴呆老年人EDS与区域性Aβ-淀粉样蛋白积累的相关性。

283名,70岁以上非痴呆老年志愿者接受PiB-PET随访以及基线睡眠评估。Epworth嗜睡评分10分以上人群定义为EDS,研究期间至少接受2次PiB-PET检查,以评估参与者Aβ积累变化情况。采用多元线性回归模型考察Aβ积累与EDS之间的关系。

参与者平均年龄77.1岁,男性占72.1%。63人(22.3%)存在EDS症状。基线EDS与前扣带、后扣带-前额叶以及顶叶区域的Aβ积累显著相关。基线前扣带和扣带回PiB 阳性患者,EDS与Aβ纵向积累的相关性最为显著。

对于无痴呆症状的老年人群,白天睡眠过多与区域性Aβ-淀粉样蛋白积累相关,白天睡眠过多是阿尔茨海默有关的病理变化的表象之一。
