【摘要】 目的探索社区老年人脑电图特征及其与认知功能的关系。方法对太原市4个社区60岁以上志愿接受调查的老年人,进行脑电图测查、认知功能测验及一般情况问卷调查,共获得合格研究对象542人。结果老年人各年龄组间脑电功率无显著差别(P>0.05)。脑电图慢波(特别是θ波)功率与MMSE得分呈负相关(P<0.05)。轻度认知障碍者相比认知功能正常者θ波功率较强(P<0.05)。结论一般人群的脑电图并不必然出现增龄性改变,脑电图慢波增强与认知测验得分偏低、轻度认知障碍有关。更多还原

【Abstract】 Objective To explore the characteristics of EEG of aged people in community and its relationship with cognitive ability.Methods A total of 542 eligible people who were aged more than sixty and willing to participate in the study were investigated by EEG,cognitive and questionnaire.Results EEG powers were not significantly different among the age groups (P>0.05),the power of slow waves was negatively correlated with MMSE score (P<0.05),especially θ wave,and was elevated in mild cognitive impairment (MCI) population (P<0.05).Conclusions EEG doesn′t change necessarily with aging.The elevation of slow wave power may be related to the MMSE decline and MCI.更多还原
