Эндокринно-метаболические изменения в детском и подростковом возрасте оказывают влияние на когнитивный статус, что сопровождается изменениями перфузии серого и белого вещества головного мозга, а также его архитектоники.</p></sec><sec><title>Цель</title><p>Цель. Верификация уровней жирных кислот (ЖК) с учетом когнитивных функций и данных нейровизуализации головного мозга у подростков с ожирением.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Исследование одноцентровое обсервационное одномоментное сравнительное. Для участия были отобраны 60 подростков в возрасте 10–16 лет. Основная исследуемая группа была сформирована из 34 человек с ожирением (SDS ИМТ≥+2,0), 26 исследуемых с нормальным весом составили контрольную группу. Расчет SDS ИМТ производился на калькуляторе Всемирной организации здравоохранения «Anthroplus». Для получения антропометрических данных использовали вертикальный ростомер МСК-233, весы и мягкую сантиметровую ленту. Уровни свободных жирных кислот в сыворотке крови определяли методом хроматомасс-спектрометрии на детекторе Agilent 7000 B. Для нейрокогнитивного тестирования использовали Монреальскую шкалу оценки когнитивных функций и тест Рея. Бесконтрастную перфузионную магнитно-резонансную томографию головного мозга выполняли на магнитно-резонасном (МР) томографе Signa Creator “Е” фирмы GE Healthcare, 1,5 Тл, China, методом маркировки артериальных спинов (Arterial Spin Labeling). Для трактографии использовали аппарат GE Sygna Creaton 1,5 Тл с использованием метода диффузионной визуализации с высоким угловым разрешением HARDI (High Angular Resolution Diffusion Imaging). Статистическая обработка полученных результатов проводилась с использованием программного обеспечения IBM SPSS Statistics.</p></sec><sec><title>Результаты</title><p>Результаты. По результатам сравнительного анализа, подростки с ожирением отличались повышенным содержанием свободных ЖК и снижением когнитивных функций (p&lt;0,05). Также получено множество статистически значимых корреляций разных групп ЖК с изменениями когнитивных характеристик, церебрального кровотока и проводящих путей.</p></sec><sec><title>Заключение</title><p>Заключение. Полученные результаты подтверждают значимую роль свободных жирных кислот в патогенезе ожирения и свидетельствуют о влиянии липотоксичности на морфологические изменения структур центральной нервной системы, что может приводить к формированию когнитивных нарушений.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>BACKGROUND</title><p>BACKGROUND: Obesity is a progressive health and economic problem of modern society. Endocrine-metabolic changes in childhood and adolescence have an impact on cognitive status, which is accompanied by changes in the perfusion of gray and white matter of the brain, as well as its architectonics.</p></sec><sec><title>AIM</title><p>AIM: Verification of fatty acid (FA) levels in relation to cognitive function and brain neuroimaging data in adolescents with obesity.</p></sec><sec><title>MATERIALS AND METHODS</title><p>MATERIALS AND METHODS: The study is a single-center observational one-stage comparative. 60 teenagers aged 10–16 years were selected to participate. The main study group was formed of 34 adolescents with obesity (SDS BMI ≥+2.0), 26 subjects with normal weight made up the control group. The calculation of SDS BMI was performed on the WHO «Anthroplus» calculator. To obtain anthropometric data, a vertical height meter MSK — 233, scales and a soft centimeter tape were used. The levels of free fatty acids in the blood serum were determined by chromatomass spectrometry on the Agilent 7000B detector. For neurocognitive testing, the Montreal Cognitive Function Assessment Scale and the Ray test were used. Contrast-free perfusion magnetic resonance imaging of the brain was performed on a Signa Creator “E” MR tomograph by GE Healthcare, 1.5 Tl, China, by Arterial Spin Labeling. For MR tractography, the GE Sygna Creaton 1.5 Tesla apparatus was used using the method of diffusion imaging with high angular resolution HARDI (High Angular Resolution Diffusion Imaging). Statistical processing of the obtained results was carried out using IBM SPSS Statistics software.</p></sec><sec><title>RESULTS</title><p>RESULTS: According to the results of a comparative analysis, adolescents with obesity were distinguished by an increased content of free LC and a decrease in cognitive functions (p &lt;0.05). A lot of statistically significant correlations of different groups of LC with changes in cognitive characteristics, cerebral blood flow and pathways were also obtained.</p></sec><sec><title>CONCLUSION</title><p>CONCLUSION: The results obtained confirm the significant role of free fatty acids in the pathogenesis of obesity and indicate the effect of lipotoxicity on morphological changes in the structures of the central nervous system, which can lead to the formation of cognitive disorders.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>жирные кислоты</kwd><kwd>дети</kwd><kwd>ожирение</kwd><kwd>церебральная  перфузия</kwd><kwd>трактография</kwd><kwd>когнитивные функции.</kwd></kwd-group><kwd-group xml:lang="en"><kwd>fatty acids</kwd><kwd>children</kwd><kwd>obesity</kwd><kwd>cerebral perfusion of the brain</kwd><kwd>tractography</kwd><kwd>cognitive functions</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа поддержана грантом Российского научного фонда в рамках конкурса 2023 г. «Проведение инициативных исследований молодыми учеными» президентской программы исследовательских проектов, реализуемых ведущими учеными, в том числе молодыми учеными: по соглашению №23-75-01034 от 14.08.2023 г.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Савина А.А., Фейгинова С.И.
