Aim. To assess cognitive functions in elderly patients with arterial hypertension (AH) depending on the presence/absence of atrial fibrillation (AF).Methods. Two groups were formed according to medical records data: 1) patients with AH and AF (n=165, median age 82 [76; 85] years), 2) patients with AH without AF (n=165, median age 75 [69; 82] years). Cognitive assessment included MMSE, MoCA, Boston naming test, ADAS-Cog.
Findings. MMSE и MoCA did not show any significant differences between the groups. Group 1 had significantly lower BNT score (28 [26;31,5]), compared to group 2 (30 [27;33]; p=0.002). Similarly, group 1 had significantly higher ADAS-Cog score, compared to group 2 - 14 [11;18] and 13 [9;17] points, respectively(p=0.024). Results. Multimorbidity in patients with AH and AF may contribute to the development of more prominent cognitive impairment, deterioration of executive function, semantic memory, as well as attention, visual-spatial ability, and working memory
