Features of the bioelectrical activity of the brain and cerebral hemodynamics in patients with hypertensive dyscirculatory encephalopathy and hypothyroidism

Encephalopathy is common in people of working age. In the last decade there was an important question the relationship of thyroid and cerebrovascular disease. The aim of the study was to investigate the characteristics of the brain’s elektorogenezis and cerebral hemodynamics in patients with hypertensive encephalopathy and related dyscirculatory hypothyroidism. We examined 97 patients, including 60 people with the HDE and the associated hypothyroidism and 37 - with the HDE without hypothyroidism. The fact, that bioelectrical activity of the brain in patients with hypothyroidism and related HDE was mostly characterized by desynchronization and disorganization of the cortical rhythm, was revealed during the study. Changes revealed by the EEG reflected the presence of metabolic and hemodynamic disturbances of the brain. Also, in patients with GDE and accompanying hypothyroidism, according to the duplex scanning of cerebral vessels, there is a significant decrease in cerebral blood supply and structural changes in vessels with a decrease in the elasticity of the common carotid artery and vertebral arteries and a decrease in cerebral reactivity accordingly. Thus, the comorbidity of HDE and hypothyroidism appears credible changes in the functional activity of the brain and decrease in cerebral reactivity.
