Mild cognitive impairment among type 2 diabetic patients attending Zagazig University outpatient clinics

Abstract Objective The incidence of mild cognitive impairment increases with age, so this study is conducted to assess the relation between mild cognitive impairment and type 2 diabetes. Methods 100 type 2 diabetic patients attending Zagazig University outpatient clinics with age range from 40-60 years old was included in the study. These patients were matched with 100 non-diabetic controls regarding age, sex and educational class. Patients with important risk factors for cognitive disorders (cerebro-vascular stroke, organ failure, mental disorders, etc.) were not included in the study. Montreal cognitive assessment (MoCA) was done for all participants by an expert examiner using MoCA tool. Results Mild cognitive impairment was confirmed in 22% of diabetic patients and in 9% of control group (p < 0.05) with total MoCA score lower in diabetic group than control one (p < 0.01). Conclusion Type 2 diabetes may be associated with lower levels of cognitive function.
