Clarification of the brain changes and the mechanisms of their development during the asymptomatic stage will ensure better results in the prevention of AH complications.<bold>Objective</bold>. The study purpose was to evaluate specific changes in the brain MRI picture, associated with AH of varying severity.<bold>Materials and methods</bold>. The study involved 82 patients with newly diagnosed asymptomatic AH, aged 45–59 years. The patients underwent MRI of the brain (T1 and T2 weighted images, FLAIR, diffusion weighted imaging with calculation of an apparent diffusion coefficient (ADC) map). We evaluated the localization and severity of white matter hyperintensity (WMH), lacunar infarcts, and dilated perivascular spaces as well as the white matter microstructure based on ADC in a visually intact white matter in areas of its potential vulnerability.<bold>Results</bold>. The earliest and most typical change is the formation of hyperintensity lesions in the juxtacortical areas of the frontal lobes. AH worsening is associated with an increase in the number of hyperintensity lesions from the frontal to occipital areas of the white brain matter and from the surface to deep brain regions as well as microstructural changes in the intact white matter in potential vulnerability areas.<bold>Conclusion</bold>. The observed high correlations between WMH and dilated semioval perivascular spaces and increased diffusion in the intact white matter as well as the absence of similar correlations for lacunar infarcts suggest that the pathophysiological basis of early brain changes in AH is increased vascular permeability, but not ischemia. The factors of a high risk of clinical symptoms include lesion extension to the posterior brain structures, multiple foci of hyperintensity in the periventricular white matter of the frontal lobes, and an increasing number of lacunar infarcts. These findings are significant for evaluating potential risk of clinical symptoms and for understanding the mechanisms of early brain injury in AH.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Введение.</bold> Артериальная гипертензия (АГ) является ведущим модифицируемым фактором риска поражения головного мозга. Уточнение закономерностей изменений в мозге и механизмов их развития на асимптомной стадии позволит добиться лучших результатов в профилактике осложнений АГ.<bold>Цель исследования</bold>. Оценить особенности МРТ изменений головного мозга при АГ разной степени тяжести.<bold>Материалы и методы.</bold> Обследовано 82 больных с асимптомной впервые диагностированной АГ (40–59 лет), проведена МРТ головного мозга (Т1 и Т2-ВИ, FLAIR, ДВИ с расчетом карт измеряемого коэффициента диффузии – ИКД). Оценивались локализация и выраженность гиперинтенсивности белого вещества (ГИБВ), лакунарных инфарктов, расширенных периваскулярных пространств, микроструктура белого вещества по ИКД в визуально неизмененном белом веществе зон его потенциальной уязвимости.<bold>Результаты</bold>. Выявлены закономерности поражения вещества головного мозга при асимптомной АГ. Наиболее ранними и типичными изменениями является образование очагов гиперинтенсивности в юкстакортикальных отделах лобных долей. С утяжелением АГ отмечается нарастание очагов гиперинтенсивности от лобных к затылочным областям белого вещества полушарий головного мозга, от поверхностных к глубоким его отделам, а также микроструктурных изменений в визуально неизмененном белом веществе зон потенциальной уязвимости.<bold>Заключение.</bold> Полученные высокие корреляции ГИБВ с расширенными семиовальными периваскулярными пространствами и повышенной диффузией в визуально неизмененном белом веществе и отсутствие таковых с развитием лакунарных инфарктов позволяют предполагать, что патофизиологической основой ранних изменений мозга при АГ является повышенная сосудистая проницаемость, а не ишемия. К факторам, указывающим на высокую вероятность развития клинических проявлений, следует отнести распространение поражения на задние отделы мозга, множественные очаги гиперинтенсивности в перивентрикулярном белом веществе лобных долей, нарастание числа лакунарных инфарктов. Полученные результаты значимы дляоценки потенциального риска развития клинических проявлений и понимания механизмов раннего повреждения головного мозга при АГ.</p></trans-abstract><kwd-group xml:lang="en"><kwd>asymptomatic hypertension</kwd><kwd>white matter hyperintensity</kwd><kwd>lacunar infarcts</kwd><kwd>intact white matter apparent diffusion coefficient</kwd><kwd>small vessel disease</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>асимптомная гипертензия</kwd><kwd>гиперинтенсивность белого вещества</kwd><kwd>лакунарные инфаркты</kwd><kwd>визуально неизмененное белое вещество</kwd><kwd>измеряемый коэффициент диффузии</kwd><kwd>болезнь малых сосудов</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Ганнушкина И.В.
