Изучить показатели нейродинамики как маркера когнитивных нарушений при неалкогольной жировой болезни печени (НАЖБП). Материалы и методы. Пациентам с диагнозом НАЖБП (n = 40), установленном на основании ультразвукового исследования печени, наличия одного из факторов кардиометаболического риска (ожирение и дислипидемия) и исключения других причин развития стеатоза печени (алкогольное, лекарственное поражение, воздействие токсинов окружающей среды, причины, связанные с питанием/проблемами со стороны кишечника, эндокринные нарушения, моногенные заболевания), проводилось лабораторное обследование, включающее общий анализ крови, биохимический анализ крови (билирубин, аспартатаминотрансфераза (АСТ), аланинаминотрансфераза (АЛТ), щелочная фосфатаза (ЩФ), гамма-глутамилтранспептидаза (ГГТ), липидограмма, глюкоза, креатинин, мочевина, общий белок и белковые фракции сыворотки крови, протромбиновый индекс (ПТИ). С целью уточнения степени фиброза использовался неинвазивный индекс фиброза-4 (FIB-4, Fibrosis-4 index). Для исключения злоупотребления алкоголем проведено тестирование c помощью опросника «The Alcohol Use Disorders Identification Test» (AUDIT). Кроме этого, для исключения наличия печеночной энцефалопатии проведен тест Рейтана (тест на цифровую последовательность). Все пациенты были протестированы по опроснику MMSE («Mini-Mental State Examination») c целью выявления деменции и преддементных когнитивных нарушений. Для исследования когнитивных функций использовался программно-аппаратный комплекс Status PF для персонального компьютера типа IBM, совместимый с адаптером регистрации реакций, разработанный на базе Кемеровского государственного университета. Изучались показатели нейродинамики, включающие определение времени сложной зрительно-моторной реакции (СЗМР) и реакцию на движущийся объект (РДО). Контрольную группу составили 30 практически здоровых добровольцев, сопоставимых по полу и возрасту. Результаты. Выявлено, что у пациентов с НАЖБП без значимого фиброза и биохимических маркеров воспаления имеются изменения показателей нейродинамики, по сравнению с контрольной группой, преобладают процессы торможения в центральной нервной системе. Заключение. Пациенты с НАЖБП имеют когнитивный дефицит, не обусловленный синдромом цитолиза и печеночной энцефалопатией. Изменения в функционировании центральной нервной системы при стеатозе печени являются отражением сложного многофакторного патогенеза основного заболевания и требуют дальнейшего изучения</p></abstract><trans-abstract xml:lang="en"><p>Aim. To investigate neurodynamic parameters as markers of cognitive impairment in non-alcoholic fatty liver disease (NAFLD). Materials and Methods. Here we enrolled forty patients with NAFLD diagnosed by liver ultrasound findings, the presence of obesity or dyslipidemia, and absence of other causes of hepatic steatosis (i.e., alcohol use, drug-induced liver injury, environmental toxins, nutritional or intestinal disorders, endocrine diseases, and monogenic conditions). The laboratory investigation included a complete blood count, comprehensive biochemical panel (bilirubin, aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, gammaglutamyl transferase, lipid profile, glucose, creatinine, urea, total protein and protein fractions, and prothrombin index). The non-invasive Fibrosis-4 (FIB-4) index was used to assess fibrosis severity. Alcohol misuse was screened using the Alcohol Use Disorders Identification Test (AUDIT). To exclude hepatic encephalopathy, the Reitan number connection test was performed. All patients were also evaluated using the Mini- Mental State Examination (MMSE) to detect dementia and pre-dementia cognitive impairments. Cognitive functions were assessed using the Status PF software with a reaction registration adapter developed at Kemerovo State University. Neurodynamic parameters included the complex visual-motor reaction time and response to a moving object. The control group consisted of 30 healthy volunteers matched by age and sex. Results. Patients with NAFLD, even in the absence of significant fibrosis or biochemical markers of inflammation, demonstrated altered neurodynamic parameters compared to the control group, and inhibition processes in the central nervous system prevailed. Conclusion. Patients with NAFLD exhibit cognitive deficits not associated with hepatocellular injury or hepatic encephalopathy. Central nervous dysfunction in hepatic steatosis reflects the complex multifactorial pathogenesis of the underlying disease and warrants further investigation</p></trans-abstract><kwd-group xml:lang="ru"><kwd>неалкогольная жировая болезнь печени</kwd><kwd>когнитивная дисфункция</kwd><kwd>метаболическая дисфункция</kwd><kwd>нейровоспаление</kwd></kwd-group><kwd-group xml:lang="en"><kwd>non-alcoholic fatty liver disease</kwd><kwd>cognitive dysfunction</kwd><kwd>metabolic dysfunction</kwd><kwd>neuroinflammation</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">Российское общество по изучению печени.
