Objective:
Comparative assessment of the cognitive status of persons over 60, depending on the presence or absence of type 2 diabetes mellitus (T2DM).
Material And Methods:
The study included 193 patients, of which 93 had no T2DM and 100 had T2DM. The mean age of patients with T2DM was 73 [68; 78] years vs. 69.2 [64; 75] years in patients without T2DM. The cognitive function was assessed using the McNair and Kahn scale, with scores over 42 indicating cognitive dysfunction and Kahn scale: in the group with T2DM, the average score was 27.0±9.36; in the group without T2DM, it was 22.0±9.60 (p<0.043). The absence of T2DM was negatively correlated with the total score on the scale for assessing the risk of cognitive impairment (p=-0.264, p<0.001). In addition, it was found that age over 75 years was significantly associated with the development of cognitive impairment, regardless of the presence of concomitant T2DM (OR=1.247, CI=95%, 1.112-1.40, p<0.001).
Conclusion:
T2DM increases the risk of developing cognitive dysfunction, which should be taken into account in older patients for the timely detection and prevention of its progression.
