Abstract:

目的:研究2型糖尿病(T2DM)的认知功能域损害特征及其与糖尿病相关指标的关系。方法:对44名T2DM及37名非糖尿病对照组(ND)进行全面的神经心理测量,并检测糖尿病相关指标[糖化血红蛋白(HbA1c)、空腹血糖、空腹胰岛素、稳态胰岛素评价指数(HOMA-IR)],并分析两者关系。结果:与ND相比,T2DM在全脑认知,语言功能,注意力和即刻记忆上无显著差异,但在执行功能(P=0.035)和延迟记忆(P=0.003)上明显受损。HbA1c和HOMA-IR与执行功能和延迟记忆呈显著性负相关(P<0.05)。多元回归分析显示,高龄(P=0.015)、高HbA1c(P=0.009)和受教育程度低(P=0.000)是认知功能障碍的独立危险因素。结论:T2DM患者选择性损害执行功能和延迟记忆,而HbA1c作为认知功能障碍的可控的独立危险因素需要引起高度重视
