Summary. The aim — to analyze the state of cognitive functions in hypertensive patients and evaluate the role of risk factors in their occurrence. Object and methods of research. We examined 90 patients with hypertension stage 1–2 (mean age 49.66±8.74 years). All patients underwent clinical and anamnestic examination, laboratory and instrumental investigation were used. Mini-Mental State Examination (MMSE) was used to objectify cognitive impairment. Results. All patients were divided into two groups depending on the presence of cognitive impairment (MMSE ≤26 and >26 points). Cognitive disorders were found in 36 (40%) patients. The most severe inverse correlation was established between the MMSE index and high levels of low-density lipoprotein cholesterol (r=–0.72; p=0.001). Risk factors that negatively affect cognitive function also turned out to be the age of the patients (r=–0.52; p=0.001), duration of hypertension (r=–0.65; p=0.001), increased body mass index (r=–0.45; p=0.001), smoking (r=–0.32; p=0.001) and male gender (r=–0.22; p=0.03). Conclusions. Timely diagnosis of cognitive impairment, detection and correction of risk factors are very important and will improve cognitive status and prevent dementia.
