Objectives: To explore the relationship between cognitive function and white matter lesions (WML) in patients with T2DM complicated with post-stroke cognitive impairment (PSCI). Methods: A total of 188 patients with T2DM complicated with ischemic stroke hospitalized in the department of neurology in Hebei general hospital from January 2018 to June 2020 were chosen in our study. According to the scores of montreal cognitive assessment scale (MoCA), the patients were divided into cognitive impairment group and cognitive normal group. The demographic, serological and imaging data of the subjects were collected to analyze the risk factors of cognitive impairment in patients with T2DM complicated with ischemic stroke and the relationship between cognitive function and different degree and different parts of WML in patients with T2DM complicated with PSCI. Results: The years of education (OR=0.770, 95%CI: 0.691-0.858, P<0.05), fibrinogen (OR=1.983, 95%CI: 1.180-3.335, P<0.05)and WML (OR=1.465, 95%CI: 1.017-2.109, P<0.05) were independent risk factors for patients with T2DM complicated with PSCI. Spearman rank correlation analysis showed that in the patients with T2DM complicated with PSCI, the total score of WML was negatively correlated with the score of MoCA, visual space ability, executive function, attention and orientation. In addition, PWML has a wider range of cognitive impairment than DWML. Conclusions: WML, especially PWML, can be used as an indicator to evaluate cognitive function of the patients with T2DM complicated with PSCI.
