reorganization of resting-state neural networks in patients with cognitive decline secondary to vascular encephalopathy (VE). Quantitative cognitive functions were evaluated using the Montreal Cognitive Assessment (MoCA) scale and compared with the organization of resting-state neural networks recorded using functional magnetic resonance imaging (fMRI).</p> <p>The <bold>aim</bold> of this work was to assess the relationship between various resting-state neural networks and cognitive function.</p> <p><bold>Materials and methods. </bold>The study involved 29 people with VE, divided into two groups: without cognitive decline (≥ 26 points on the MoCA) and with cognitive impairment (24–18 points on the MoCA). Connectivity between different brain regions was evaluated in all patients using resting-state fMRI, with SPM-12 and CONN18b software applications in Matlab.</p> <p><bold>Results and conclusion.</bold> Statistically significant differences in connectivity were found between groups in the dorsal attention network, visual network, and sensorimotor networks, as well as in the left parahippocampal cortex. New, negative connectivity was observed alongside cognitive decline, which, together with reduced connectivity in resting-state neural networks, can be considered an obligatory sign accompanying cognitive impairment in VE.</p></abstract><trans-abstract xml:lang="ru"><p>Оценивали реорганизацию коннективности нейросетей покоя при когнитивном снижении у больных дисциркуляторной энцефалопатией (ДЭ). Количественно когнитивные функции исследовали с помощью Монреальской шкалы оценки когнитивных функций (МоСА) и сопоставляли с организацией нейросетей покоя, зарегистрированных с помощью функциональной магнитно-резонансной томографии покоя.</p> <p><bold>Цель</bold> работы — оценка взаимосвязи различных нейросетей покоя с когнитивными функциями.</p> <p><bold>Материалы и методы. </bold>В исследовании участвовали 29 человек с ДЭ, разделенных на две группы: без когнитивного снижения (≥ 26 баллов по шкале МоСА) и с когнитивными расстройствами (24–18 баллов по шкале МоСА).

При когнитивном снижении наблюдалось появление новых, негативных коннективностей, что наряду с сокращением коннективности в нейросетях покоя может рассматриваться как облигатный признак, сопровождающий когнитивные дисфункции при ДЭ.</p></trans-abstract><kwd-group xml:lang="en"><kwd>vascular encephalopathy</kwd><kwd>neuroimaging</kwd><kwd>functional resting-state MRI</kwd><kwd>Montreal Cognitive Assessment scale</kwd><kwd>connectivity</kwd><kwd>cognitive function</kwd><kwd>resting-state neural networks</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>дисциркуляторная энцефалопатия</kwd><kwd>нейровизуализация</kwd><kwd>функциональная МРТ покоя</kwd><kwd>Монреальская шкала оценки когнитивных функций</kwd><kwd>коннективность</kwd><kwd>когнитивные функции</kwd><kwd>нейросети покоя</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Suslina Z.A., Illarioshkin S.N., Piradov M.A. [Neurology and neuroscience - development prognosis].
