The akinetic-rigid (AR) and tremor-dominant (TD) types of PD differ not only in motor manifestations, but also in the severity of non-motor symptoms, including cognitive impairment (CI). It is the PD heterogeneity study that can achieve the task of creating a modern personalized therapy for this disease.</p><sec><title>Objective</title><p>Objective: to study the characteristics of cerebral glucose metabolism in CI in patients with AR and TD PD.</p></sec><sec><title>Patients and methods</title><p>Patients and methods. Examinations were made in 69 patients with PD (the TD and AR subtypes were in 23 and 46 patients, respectively). Their cognitive status was assessed using the Mini-mental State Examination, the Montreal Cognitive Assessment, the Frontal Assessment Battery, and the Clock Drawing Test. 18F-fluorodeoxyglucose positron emission tomography was performed according to the standard procedure; glucose metabolism rate (GMR) was determined in different Brodmann areas (BA).</p></sec><sec><title>Results and discussion</title><p>Results and discussion. GMR in the frontal areas (right BA 6, 8, 9, 46 and left BA 46) was lower in the AR group that in the TD one (p&lt; 0.05). The severity of CI in the AR group correlated with GMR in the parietal and posterior cingulate cortex (BA 7, 23, 26, 29, 30, and 31). The TD group showed correlations of the values of cognitive tests mainly with GMR in the frontal and anterior cingulate cortex (BA 6, 8–11, 24), and in the parietal (BA 7) and temporal cortices (BA 22). The only area, in which GMR correlated with cognitive performance in both groups, was BA 7.</p></sec><sec><title>Conclusion</title><p>Conclusion. Two distinct patterns of GMR were identified in AR and TD within the general pattern of decreased cerebral glucose metabolism, which was specific for CI in PD. The findings may suggest that there are two different CI pathogenetic mechanisms associated with the clinical subtypes of PD.</p></sec></abstract><trans-abstract xml:lang="ru"><p>Болезнь Паркинсона (БП) — заболевание, характеризующееся выраженной фенотипической гетерогенностью. Акинетико-ригидная (АРФ) и дрожательная (ДФ) формы БП различаются не только двигательными проявлениями, но и выраженностью немоторных симптомов, в том числе когнитивных нарушений (КН). Именно в изучении проблемы гетерогенности БП кроется решение задачи создания современной персонализированной терапии этого заболевания.</p><p>Цель исследования – изучение особенностей церебрального метаболизма глюкозы при КН у больных с АРФ и ДФ БП.</p><sec><title>Пациенты и методы</title><p>Пациенты и методы. Были обследованы 69 пациентов с БП, из них 23 – с ДФ и 46 – с АРФ. Когнитивный статус оценивался с помощью краткой шкалы оценки психического статуса, Монреальской шкалы оценки когнитивных функций, батареи тестов лобной дисфункции, теста рисования часов. Позитронно-эмиссионная томография с [18F]-фтордезоксиглюкозой выполнялась по стандартной методике; определялась скорость метаболизма глюкозы (СМГ) в разных полях Бродмана (ПБ).</p></sec><sec><title>Результаты и обсуждение</title><p>Результаты и обсуждение. В группе АРФ, по сравнению с ДФ, наблюдалась меньшая СМГ в лобных областях – ПБ 6, 8, 9, 46 в правом полушарии и ПБ 46 в левом полушарии (p&lt; 0,05). Выраженность КН в группе АРФ коррелировала с СМГ в теменной и задней поясной коре (ПБ 7, 23, 26, 29, 30, 31). В группе ДФ наблюдались корреляции показателей когнитивных тестов преимущественно с СМГ в лобной и передней поясной коре (ПБ 6, 8–11, 24), а также теменной (ПБ 7) и височной коре (ПБ 22). Единственная область, СМГ в которой коррелировала с когнитивными показателями в обеих группах, – ПБ 7.</p></sec><sec><title>Заключение</title><p>Заключение. В рамках общего паттерна снижения церебрального метаболизма глюкозы, характерного для КН при БП, выявлены два разных паттерна СМГ при АРФ и ДФ. Полученные результаты позволяют предположить существование разных механизмов патогенеза КН, ассоциированных с клиническим подтипом БП.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>болезнь Паркинсона</kwd><kwd>акинетико-ригидная форма</kwd><kwd>дрожательная форма</kwd><kwd>когнитивные нарушения</kwd><kwd>позитронноэмиссионная томография</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Parkinson’s disease</kwd><kwd>akinetic-rigid type</kwd><kwd>tremor-dominant type</kwd><kwd>cognitive impairment</kwd><kwd>positron emission tomography</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">Милюхина ИВ, Карпенко МН, Тимофеева АА, Скоромец АА.
