Изучить функциональные изменения таламуса, миндалевидного комплекса и гиппокампальной области методом функциональной МРТ в состоянии покоя и определить их клиническую и прогностическую значимость при различных типах течения РС.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Обследовано 68 пациентов с диагнозом рассеянного склероза (РС): 40 больных с ремиттирующим типом течения (РРС) в стадии ремиссии и 28 — с вторично-прогрессирующим РС без признаков активности и прогрессирования (ВПРС). Группу контроля составили 10 здоровых человек соответствующего возраста и пола без неврологических и соматических заболеваний. Всем пациентам и контрольной группе была выполнена МРТ головного мозга на томографе Siemens Tim Trio с индукцией магнитного поля 3,0 Тл, использованием контрастного усиления, протоколов Т1 градиентного эха, REST-BOLD и последующей обработкой полученных данных при помощи программного обеспечения CONN 19с. Клиническая оценка проводилась по шкалам: EDSS, MSSS, MMSE, FAB, MoCA, SDMT, теста Бека и HADS. Всем пациентам было выполнено МРТ головного мозга и МР-морфометрия с помощью программы Freesurfer 6.0.</p></sec><sec><title>Результаты</title><p>Результаты. В ходе исследования были обнаружены различные паттерны изменения функциональных связей: у пациентов с ВПРС происходит уменьшение интенсивности связей таламуса с другими структурами головного мозга и уменьшение их количества по сравнению с больными с РРС, у которых количество связей существенно выше. Кроме того, у пациентов с ВПРС происходит значительное снижение параметров коннективности гиппокампальной формации слева, а в случае с миндалевидным комплексом — справа, это проявляется в суммарном уменьшении интенсивности связей с другими структурами головного мозга и уменьшении их количества. Нейродегенеративный процесс представлен уменьшением объемов хвостатого ядра и скорлупы, увеличением объема 3-го и боковых желудочков, увеличением объема СМЖ, наличием «черных дыр». От длительности заболевания зависит объем 3-го и боковых желудочков, объем СМЖ (общая нейродегенерация). На степень инвалидизации (EDSS) влияют объемы хвостатого ядра, бледного шара, прилежащего ядра и ствола головного мозга. В свою очередь на когнитивное снижение оказывают влияние объем таламуса, базальных ядер, ствола головного мозга, объем боковых желудочков и уменьшение объемов белого вещества и коры мозжечка.</p></sec><sec><title>Заключение</title><p>Заключение. Таким образом, метод функциональной МРТ в состоянии покоя вносит дополнительный вклад в понимание нейродегенеративных процессов при различных фенотипах рассеянного склероза. А динамическая оценка и наблюдение за объемом подкорковых образований головного мозга с помощью МР-морфометрии может выступать в роли прогностического фактора при переходе ремиттирующе-рецидивирующего фенотипа рассеянного склероза во вторично-прогрессирующий фенотип.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Objective</title><p>Objective. The aim of study: to investigate the functional changes in the thalamus, amygdala, and hippocampal region using functional MRI at rest and determine their clinical significance in various types of MS.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. 68 patients with a diagnosis of multiple sclerosis (MS) were examined: 40 patients with a relapsing-remitting MS (RRMS) in remission and 28 patients with secondary progressive MS without signs of activity and progression (SPMS). The control group consisted of 10 healthy people of the appropriate age and gender without neurological and somatic diseases. All patients and controls underwent MRI of the brain on a Siemens Tim Trio tomograph with a magnetic field induction of 3.0 TL, using contrast enhancement, T1 gradient echo protocols, REST-BOLD, and subsequent processing of the data obtained using CONN 19с software.</p></sec><sec><title>Results and conclusion</title><p>Results and conclusion. In the course of the study, various patterns of changes in functional connections were found: in patients with RRMS, there is a decrease in the intensity of connections of the thalamus with other brain structures and a decrease in their number. In patients with RRMS, a greater number and intensity of connections within the thalamus and other structures of the brain were detected compared to SPMS. In patients with RRMS, there is a significant decrease in the connectivity parameters of the hippocampal formation, which is expressed on the left, and in the case of the amygdala complex – on the right, this is manifested in a total decrease in the intensity of connections with other brain structures and a decrease in their number. Thus, the method of functional MRI at rest makes an additional contribution to the understanding of neurodegenerative processes in various phenotypes of multiple sclerosis.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>вторично-прогрессирующий РС</kwd><kwd>гиппокамп</kwd><kwd>миндалина</kwd><kwd>рассеянный склероз</kwd><kwd>РС</kwd><kwd>таламус</kwd><kwd>функциональная коннективность</kwd><kwd>функциональная МРТ</kwd></kwd-group><kwd-group xml:lang="en"><kwd>amygdala</kwd><kwd>fMRI</kwd><kwd>functional connectivity</kwd><kwd>hippocampus</kwd><kwd>multiple sclerosis</kwd><kwd>MS</kwd><kwd>secondary progressive MS</kwd><kwd>thalamus</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Multiple Sclerosis International Federation.
