Abstract

Introduction: Electroencephalogram (EEG) has the potentials to decipher the neural underpinnings of cognitive processes in clinical and healthy populations. Objective: The current systematic review is intended to examine the functional brain changes underlying cognitive dysfunctions in T2DM patients. Methods: The review was conducted on studies published in the PubMed, WebofScience, Cochrane, PsycInfo database till June 2021. The keywords used were electroencephalogram, T2DM, cognitive impairment/dysfunction. We considered studies using resting-state EEG and ERP. The preferred reporting items for systematic reviews and meta-analysis (PRISMA) guidelines were followed to compile the studies. Results: The search yielded a total of 2384 studies. Finally, 16 independent studies were included. There was a pattern of a shift in EEG power observed from higher to lower frequencies in T2DM patients, though to a lesser degree than Alzheimer's disease patients. P300 latency was increased in T2DM patients mainly over frontal, parietal, and posterior regions. P300 and N100 amplitudes were decreased in T2DM patients than in healthy controls. Conclusion: The results indicate that T2DM has consequences for cognitive functions, and it finds a place in the continuum of healthy cognition to dementia.

2型糖尿病患者与认知功能相关的脑电活动变化:一项系统综述
脑电图(EEG)有潜力破译临床和健康人群认知过程的神经基础。目的:本系统综述旨在探讨T2DM患者认知功能障碍背后的脑功能改变。方法:对截至2021年6月在PubMed、WebofScience、Cochrane、PsycInfo数据库中发表的研究进行综述。关键词:脑电图、T2DM、认知功能障碍。我们考虑了使用静息状态EEG和ERP的研究。按照系统评价和荟萃分析(PRISMA)指南的首选报告项目进行研究。结果:共检索到2384项研究。最后,纳入了16项独立研究。在2型糖尿病患者中观察到脑电图功率从高频率到低频率的变化模式,尽管这种变化程度低于阿尔茨海默病患者。T2DM患者P300潜伏期增加主要发生在额、顶叶和后叶区域。T2DM患者的P300和N100波幅较健康对照降低。结论:T2DM对认知功能有影响,并在健康认知到痴呆的连续过程中占有一席之地。
