Современные нейровизуализационные исследования показывают, что кататония связана со специфическими формами дисфункции кортико-стриатально-таламических систем, с особым вовлечением фронто-стриатальных структур, регулирующих двигательный контроль и исполнительные функции.</p></sec><sec><title>Цель</title><p>Цель. Охарактеризовать структуру нейрокогнитивного дефицита при эндогенных расстройствах с кататонической симптоматикой с помощью факторного анализа, выявив различные когнитивные профили, связанные с дисфункцией кортико-стриарной и височно-теменной систем, и оценить модифицирующее влияние сопутствующей аффективной (преимущественно депрессивной) патологии.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Исследованы 139 пациентов: основная группа (n = 69) с эндогенными расстройствами, включая кататоническую симптоматику, разделенная на подгруппы без (n = 35) и с выраженной депрессивной симптоматикой (n = 34), и контрольная группа (n = 70). Кататонию оценивали с помощью шкалы Буша–Фрэнсиса (BFCRS). Нейрокогнитивная оценка включала шкалы BACS, MoCA и FAB. Применен факторный анализ с чередованием переменных. Результаты. Факторный анализ выявил различные когнитивные структуры. При кататонии без аффективной симптоматики выявлялись три фактора: фронто-стриатный (47,2 % дисперсии), темпоро-париетальный (26,3 %) и гиппокампальный (19,8 %). При сопутствующей аффективной патологии – два фактора: фронто-лимбический (53,7 %) и фронто-стриатный (30,1 %). MANOVA выявил значимые групповые различия во всех когнитивных областях (d = 0,52–1,31, p &lt; 0,001).</p></sec><sec><title>Заключение</title><p>Заключение. Кататонические расстройства демонстрируют различные факторно-аналитические когнитивные профили, отражающие специфическую дисфункцию кортико-стриарных и темпоро-париетальных систем. Сопутствующая аффективная патология трансформирует структуру когнитивных нарушений в сторону фронто-лимбической дисфункции, что указывает на необходимость дифференцированной реабилитации.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. Contemporary neuroimaging studies reveal that catatonia is associated with specific dysfunction patterns in cortico-striatal-thalamic networks, with particular involvement of fronto-striatal circuits regulating motor control and executive functions. Factor-analytic approaches to cognitive assessment can identify distinct neuropsychological profiles reflecting underlying neural network alterations in catatonic disorders.</p></sec><sec><title>Objective</title><p>Objective. To characterize the structure of neurocognitive deficits in endogenous disorders with catatonic symptomatology through factor analysis, identifying distinct cognitive profiles associated with cortico-striatal and temporo-parietal network dysfunction, and to evaluate the modifying effect of affective comorbidity on these patterns.</p></sec><sec><title>Material and Methods</title><p>Material and Methods. The study included 139 patients: main group (n = 69) with endogenous disorders including catatonic symptomatology, divided into subgroups without (n = 35) and with pronounced depressive symptomatology (n = 34), and control group (n = 70) with similar subdivision. Catatonia was assessed using Bush-Francis Scale (BFCRS). Neurocognitive evaluation included BACS battery, MoCA and FAB scales. Factor analysis with varimax rotation was applied to identify cognitive deficit structure. Statistical analysis included MANOVA with Bonferroni correction.</p></sec><sec><title>Results</title><p>Results. Factor analysis revealed distinct cognitive structures. In catatonia without affective symptomatology, three factors emerged: (1) a fronto-striatal factor (47.2 % of variance), comprising executive functions, psychomotor speed, and inhibitory control; (2) a temporo-parietal factor (26.3 % of variance), including visuospatial functions and constructive praxis; and (3) a hippocampal factor (19.8 % of variance), associated with episodic memory and delayed recall. In the presence of affective comorbidity, two factors were identified: (1) a fronto-limbic factor, accounting for 53.7% of the variance and encompassing attention, working memory, and emotional regulation; and (2) a fronto-striatal factor, accounting for 30.1 % of the variance and encompassing psychomotor speed and executive functions. MANOVA revealed significant group differences across all cognitive domains (d = 0.52–1.31, p &lt; 0.001). Two-factor analysis showed main effect of catatonia (F = 31.2, p &lt; 0.001, η² = 0.19), moderate effect of affectivity (F = 12.4, p &lt; 0.01, η² = 0.08) and their interaction (F = 7.8, p &lt; 0.01, η² = 0.05).</p></sec><sec><title>Conclusion</title><p>Conclusion. Catatonic disorders demonstrate distinct cognitive profiles on factor analysis, reflecting specific cortico-striatal and temporo-parietal network dysfunction. Affective comorbidity transforms the cognitive structure toward fronto-limbic involvement, indicating the need for differentiated rehabilitation targeting specific neural networks.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>кататония</kwd><kwd>кортико-стриарная система</kwd><kwd>когнитивный факторный анализ</kwd><kwd>нейропсихологические профили</kwd><kwd>фронто-лимбическая дисфункция</kwd></kwd-group><kwd-group xml:lang="en"><kwd>catatonia</kwd><kwd>cortico-striatal networks</kwd><kwd>cognitive factor analysis</kwd><kwd>neuropsychological profiles</kwd><kwd>fronto-limbic dysfunction</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">Hirjak D, Rogers JP, Wolf RC, Kubera KM, Fritze S, Wilson JE, et al.
