摘要
2型糖尿病患者因长期代谢紊乱造成的认知功能障碍已经成为当前关注的重点。本文利用多通道同步方法——基于相位同步的S估计器对脑电信号进行同步分析,以期发现与糖尿病轻度认知障碍有关的脑电特性。结果显示:糖尿病轻度认知障碍患者与正常对照组相比各脑区各频段的S值均减小,尤其是δ和α频段显著降低,表明脑电同步值降低;患者MoCA得分与S值在α频段具有显著的正相关性。
The cognitive impairment of type 2diabetes patients caused by long-term metabolic disorders has been the current focus of attention.In order to find the related electroencephalogram（EEG）characteristics to the mild cognitive impairment（MCI）of diabetes patients,this study analyses the EEG synchronization with the method of multichannel synchronization analysis--S estimator based on phase synchronization.The results showed that the S estimator values in each frequency band of diabetes patients with MCI were almost lower than that of control group.Especially,the S estimator values decreased significantly in the delta and alpha band,which indicated the EEG synchronization decrease.The MoCA scores and S value had a significant positive correlation in alpha band.
