Objective To study the assessment implement and its related factors in type 2 diabetic patients with mild cognitive impairment(MCI).Methods Montreal Cognitive Assessment(MoCA)(Beijing Version)was chosen as cognition assessment implement.58 type 2 diabetic patients with MCI were enrolled as the research group and 30 type 2 diabetic patients with normal cognitive function as control.HbA_(1C),blood lipid,urine microalbumin,liver and renal functions were measured in all subjects.Results Compared with control group,the blood levels of HbA_(1C)[(10.48±2.38 vs 9.28±2.19)%,P<0.05],total cholesterol[(4.87±1.18 vs 4.18±1.04)mmol/L,P<0.01],and low-density lipeprotein-cholesterol[LDL-C,(2.97±0.87 vs 2.37±0.61)mmol/L,P<0.01]increased,and high-density lipoprotein-cholesterol decreased[(1.084±0.34 vs 1.25±0.33)mmoL/L,P<0.05]in MCI group.There were significant differences in the duration of diabetes mellitus,diabetic retinopathy,body mass index,and abdominal circumference between MCI group and control group(all P<0.05).There were no significant differences in blood triglycerides,alanine aminotransferase(ALT),aspartate aminotransferase(AST),creatinine,and urine microalbumin between the two groups.MoCA scores were negatively correlated with HbA_(1C)(r=-0.396,P=0.002)and LDL-C(r=-0.275,P=0.036)in MCI group.Multiple regression analysis showed that HbA_(1C) was a significantly independent determinant for the MoCA scores.Conclusion The risk factors such as longer duration of diabetes mellitus.more diabetea mellitus complications,obesity,dyslipidemia,and inefficient control of blood glucoge all contribute to the development and aggravation of cognitive impairment.Therefore,good control of blood glucose and lipids,and reduction of complication and body weight may help to improve the cognitive function.

Montreal cognitive assessment(MoCA, Beijing Version) was chosen as cognition assessment implement. 63 patients suffering from type 2 diabetes mellitus with mild cognitive impairment (MCI) were chosen to form a research group, and 27 patients with type 2 diabetes mellitus and normal cognitive function served as a control group. It was found that atherosclerosis played an important role in the pathogenesis of MCI in type 2diabetes, therefore, early prevention and management of atherosclerosis may help to improve the cognitive function.
