New approaches in the study of the CM1 symptom complex include cognitive dysfunction and the mechanisms of its formation. Of great research interest is the previously unexplored relationship of cognitive dysfunction in patients with CM1 with different degree of tonsils ectopia.Objective: to identify the features of the cognitive status in patients with CM1 and to assess the relationship of CM1 with the degree of cerebellar tonsil ectopia.Patients and methods. The study included 110 adult patients with CM1 aged 25.61±6.9 years. The control group consisted of 50 people aged 26.36±5.0 years without signs of CM1 and other organic brain pathology. The assessment of neuroimaging parameters was carried out on a magnetic resonance tomograph with a magnetic field induction of 1.5 T. Cognitive status was assessed using the Mini-Mental State Examination (MMSE), the Montreal Cognitive Assessment (MoCA) and the Trail Making Test (TMT; subtests A and B – TMTA, TMTB).Results and discussion. When assessing the cognitive status of patients with СM1 and those of the control group, statistically significant differences were determined in the domains of executive functioning, visuospatial skills, attention, delayed recall, and speech. All patients, regardless of the degree of cerebellar tonsil ectopia, had lower cognitive performance compared to the control group. There was a trend towards an increase in cognitive deficit with an increase in the degree of ectopia of the cerebellar tonsils. The most pronounced cognitive deficit with a significant decrease in the domains of executive functioning, visuospatial skills, attention, delayed recall and speech was noted in a subgroup of patients with a high degree of tonsil ectopia.Conclusion. The presence of a specific cognitive deficit in patients with СM1 was revealed, and a significant relationship between cognitive dysfunction and the degree of cerebellar tonsil ectopia was established.</p></abstract><trans-abstract xml:lang="ru"><p>Использование нейровизуализационной диагностики мальформации Киари 1-го типа (МК1) позволяет расширить представления как о спектре клинических проявлений аномалии, так и о ее радиологических характеристиках. К новым направлениям в изучении симптомокомплекса МК1 относятся когнитивная дисфункция и механизмы ее формирования. Большой исследовательский интерес представляет ранее не изучавшаяся связь когнитивной дисфункции у пациентов с МК1 с эктопией миндалин мозжечка той или иной степени.Цель исследования – выявить особенности когнитивного статуса у пациентов с МК1 и оценить взаимосвязь МК1 со степенью эктопии миндалин мозжечка.Пациенты и методы. В исследование было включено 110 взрослых пациентов с МК1 в возрасте 25,61±6,9 года. Контрольную группу составили 50 человек в возрасте 26,36±5,0 года без признаков МК1 и иной органической патологии мозга. Оценка нейровизуализационных показателей проводилась на магнитно-резонансном томографе с индукцией магнитного поля 1,5 Тл. Когнитивный статус оценивали при помощи Краткой шкалы оценки психического статуса (Mini-Mental State Examination, MMSE), Монреальской когнитивной шкалы (Montreal Cognitive Assessment, MоCA) и теста прокладывания пути (Trail Making Test, TMT; субтесты А и В – TMTA, TMTB).Результаты и обсуждение. При оценке когнитивного статуса пациентов с МК1 и лиц контрольной группы были получены статистически значимые различия в доменах исполнительного функционирования, зрительно-пространственных навыков, внимания, отсроченного воспроизведения и речи. Все пациенты, вне зависимости от степени эктопии миндалин мозжечка, имели более низкие когнитивные показатели по сравнению с контрольной группой. Была отмечена тенденция к нарастанию когнитивного дефицита с увеличением степени эктопии миндалин мозжечка. Наиболее выраженный когнитивный дефицит со значимым снижением в доменах исполнительного функционирования, зрительно-пространственных навыков, внимания, отсроченного воспроизведения и речи был отмечен в подгруппе пациентов с высокой степенью эктопии миндалин.Заключение. Выявлено наличие специфического когнитивного дефицита у пациентов с МК1, а также установлена значимая связь когнитивной дисфункции со степенью эктопии миндалин мозжечка.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>мальформация Киари 1-го типа</kwd><kwd>когнитивная дисфункция</kwd><kwd>степень эктопии миндалин мозжечка</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Chiari malformation type 1</kwd><kwd>cognitive dysfunction</kwd><kwd>the degree of ectopia of the tonsils of the cerebellum</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">McVige JW, Leonardo J.
