Materials and methods. The study included 196 patients, aged from 65 to 99 years with the arterial hypertension, but with no evidence of hemodynamically significant stenosis of the brachiocephalic system. Patients were divided into four groups: one group included patients aged 90-99 years, the second group included patients aged 85-89 years, in the third group there were 75-84 years old patients, and the fourth one - 65-74 years old patients. All patients underwent neuropsychological testing to detect cognitive impairment by the geriatrician. Brachiocephalic arteries of patients were examined on the ultrasonic device Aplio ™ 500 by Toshiba. The study of brain structures was carried out using the magnetic resonance scanner GE Signa Infinity HD 1.5T. Results. Changes in the parameters of cerebral hemodynamics may be due not only to the presence of hemodynamically significant stenosis, but also to hemodynamically signif-icant tortuosity of MAH, that develop within long-term arterial hypertension. The results of this study indicated the rationality of using a comprehensive application of instrumental research methods, such as ultrasound examination of brachiocephalic vessels and magnetic resonance imaging of brain structures. Conclusions. Pathological deformations of ССА and ICС, which develop as a result of long-term non-correctable arterial hypertension, can be considered as one of the possible pathogenic mechanisms of cognitive deficits development. Complex use of ultrasound exam-ination of carotid arteries and magnetic resonance imaging of the brain allows one to register and differentiate patterns specific for each method of study among older age group patients with predementia and dementia state to exclude other causes of cognitive decline. The need for early detection of the cognitive decline causes is provoked by the necessity and im-portance of timely treatment of these conditions.
