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。
Patients with type 2 diabetes due to long-term metabolic disorders caused by cognitive dysfunction has become the current focus of attention. In this paper, we use the multi-channel synchronization method - S phase estimator based on phase synchronization to synchronously analyze the EEG signals, in order to find the EEG characteristics related to mild cognitive impairment in diabetes. The results showed that compared with the normal control group, the S values of all the brain regions decreased in patients with mild cognitive impairment of diabetes, especially in the δ and α bands, indicating that the EEG synchronization value decreased. The MoCA score and S value There is a significant positive correlation in the alpha frequency band.
