OBJECTIVE: Diabetes mellitus is a highly challenging worldwide epidemic affecting the health of millions of people. This study investigates the impact of glycated hemoglobin (HbA1c) and duration of diabetes on cognitive functions in type 2 diabetic patients and evaluates whether high HbA1c or duration is more harmful to impair cognitive functions.
PATIENTS AND METHODS: In this study, 202 participants, 101 patients with type 2 diabetes mellitus (T2DM), and 101 age, gender, height, and weight-matched controlled subjects were enlisted. The HbA1c was determined using a clover analyzer, and cognitive functions were evaluated using “Cambridge Neuropsychological Test Automated Battery (CANTAB).
RESULTS: The results revealed that AST Mean correct latency, AST Mean correct latency (congruent), AST Mean correct latency (incongruent), CRT Mean correct latency, MOT Mean latency, SWM Between errors, SWM Strategy, PRM Percent correct responses were meaningly delayed in the diabetic group as compared to the control group (p < 0.0001).
CONCLUSIONS: High HbA1c or uncontrolled DM and duration of diabetes cause cognitive function impairment. Moreover, the cognitive functions declined were significantly linked with the duration of the disease and high HbA1c. While treating diabetic patients, physicians must monitor the HbA1c level as reasonable glycemic control is vital to curtail the complications of DM, including cognitive function impairment.Free PDF Download
