All patients underwent brain MRI according to an epilepsy protocol and diffusion MRI (3 Tesla). Voxel-based morphometry was performed using the CAT12 module in MATLAB 2018. Modeling of 32 white matter tracts was conducted automatically in DSI Studio 2022 using the HCP842 atlas-based algorithm.</p> <p><bold>Results.</bold> Patients with TLE showed significant gray matter volume reduction in 54 regions and white matter volume reduction in 23 regions. Conversely, white matter volume increase was observed in 6 regions. Subgroup analysis of different structural abnormalities (hippocampal sclerosis, focal cortical dysplasia, low-grade glioneuronal tumor, cavernoma, encephalocele) revealed gray matter volume increase in 9 regions and white matter increase in 1 region. Additionally, white matter volume increase was documented in 3 regions in patients with bitemporal discharges and in 2 regions with hippocampal sclerosis. Microstructural changes were detected bilaterally — both ipsilateral and contralateral to the epileptogenic focus. Some changes indicated enhanced microstructural integrity and compaction of myelin fibers.</p> <p><bold>Conclusion. </bold>Patients with TLE exhibit not only morphometric and microstructural signs of degenerative changes in cerebral gray and white matter, but also markers of compensatory neuroplastic mechanism activation.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Введение.</bold> Исследование морфометрических и микроструктурных характеристик мозга у пациентов с височной эпилепсией (ВЭ) представляет собой одно из наиболее активно развивающихся направлений в области нейровизуализации.</p> <p><bold>Цель</bold> исследования: количественно оценить изменения морфометрических и микроструктурных параметров серого и белого вещества головного мозга у пациентов с ВЭ.</p> <p><bold>Материалы и методы.</bold> В исследование были включены 29 пациентов с ВЭ и 26 здоровых лиц в возрасте 22–64 лет. Всем пациентам были проведены МРТ головного мозга по эпилептологическому протоколу и диффузионная МРТ (3 Тл). Для воксель-ориентированной морфометрии использовали модуль CAT12 в среде MATLAB 2018. Моделирование 32 трактов белого вещества выполняли в автоматическом режиме в программе «DSI Studio 2022» с использованием алгоритма, основанного на атласе HCP842.</p> <p><bold>Результаты.</bold> У пациентов с ВЭ обнаружено значительное снижение объёма серого вещества в 54 областях и объёма белого вещества — в 23 областях. При этом в 6 областях наблюдалось увеличение объёма белого вещества. Анализ подгрупп с различными видами структурной патологии (склероз гиппокампа, фокальная корковая дисплазия, глионейрональная опухоль низкой степени злокачественности, кавернома, энцефалоцеле) показал увеличение объёма серого вещества в 9 областях и белого вещества — в 1 области. Кроме того, увеличение объёма белого вещества было зафиксировано в 3 областях у пациентов с битемпоральными разрядами и в 2 областях при склерозе гиппокампа. Микроструктурные изменения выявлены в обоих полушариях — как на стороне эпилептогенного очага, так и на противоположной. Часть этих изменений указывала на повышение микроструктурной целостности и уплотнение миелиновых волокон.</p> <p><bold>Заключение. </bold>У пациентов с ВЭ выявляются не только морфометрические и микроструктурные признаки дегенеративных изменений серого и белого вещества головного мозга, но и маркеры активации компенсаторных нейропластических механизмов.</p></trans-abstract><kwd-group xml:lang="en"><kwd>temporal lobe epilepsy</kwd><kwd>hippocampal sclerosis</kwd><kwd>white matter</kwd><kwd>epileptogenic network</kwd><kwd>voxel-based morphometry</kwd><kwd>tractography</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>височная эпилепсия</kwd><kwd>склероз гиппокампа</kwd><kwd>белое вещество</kwd><kwd>эпилептогенная сеть</kwd><kwd>воксель-ориентированная морфометрия</kwd><kwd>трактография</kwd></kwd-group><funding-group><award-group><funding-source><institution-wrap><institution xml:lang="en">Ministry of Science and Higher Education of the Russian Federation</institution></institution-wrap><institution-wrap><institution xml:lang="ru">Министерство науки и высшего образования Российской Федерации</institution></institution-wrap></funding-source><award-id>075-01384-23-04</award-id></award-group><funding-statement xml:lang="en">The study was performed as part of the state assignment of the Russian Center of Neurology and Neurosciences (No. 123120100066-8).</funding-statement><funding-statement xml:lang="ru">Работа выполнена в рамках государственного задания Российского центра неврологии и нейронаук (№ 123120100066-8).</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Hainc N, McAndrews MP, Valiante T, et al.
