Effective therapy of these patients is one of the most urgent problems of outpatient neurological practice.</p><sec><title>Objective</title><p>Objective: to evaluate the efficiency and safety of long-term administration of vinpocetine (Cavinton Comforte) in the treatment of dizziness in patients with CCVI.</p></sec><sec><title>Patients and methods</title><p>Patients and methods. A total of 139 patients took part in an open-label parallel-group clinical study. Vinpocetine (Cavinton Comforte) and vestibular exercises were prescribed in Group 1 (n=69); vestibular exercises were used in Group 2 (n=70). The efficiency of treatment was evaluated using a visual analog scale (VAS) in assessing vertigo and dizziness, the Dizziness Handicap Inventory (DHI), the Drug Attitude Inventory (DAI), the Montreal Cognitive Assessment (MoCA), the 5-point Likert scale, and videonystagmographic tests. Plasma brain-derived neurotrophic factor (BDNF) concentrations were analyzed before and after treatment. The total duration of the investigation was 8 months (6 months of therapy and 2 months of follow-up after therapy discontinuation).</p></sec><sec><title>Results and discussion</title><p>Results and discussion. The administration of vinpocetine significantly decreased the subjective intensity of vertigo and dizziness (on the VAS) and improved daily activities in patients (on the DHI) and a number of parameters according to the video nystagmographic tests: pursuit and saccadic eye movement tests. According to the DNI scores, the improvement changes in the patients' condition significantly correlated with increased plasma BDNF expression throughout the follow-up (Pearson's correlation coefficient&gt;0.5). The use of vinpocetine could improve cognitive functions (on the MoCA and the 5-point Likert scale) and increase patient adherence to the therapy performed (on the DAI). The clinically significant effect in improving the statodynamic function was shown by vinpocetine at 2 months of its administration and was highest at 5 months; there was a significant improvement in cognitive function at 6 months. The long-term use of vinpocetine was not associated with the risk of serious adverse events.</p></sec><sec><title>Conclusion</title><p>Conclusion. The findings allow vinpocetine to be recommended for long-term (at least 5 months) treatment of vertigo, dizziness, and cognitive impairment in patients with CCVI, in this case, the clinical effect is achieved through stimulating neuroplasticity, inducing BDNF synthesis in particular.</p></sec></abstract><trans-abstract xml:lang="ru"><p>Жалобы на головокружение часто встречаются у больных с диагнозом хронической недостаточности мозгового кровообращения (ХНМК). Эффективная терапия таких пациентов является одной из наиболее актуальных проблем амбулаторной неврологической практики.</p><p>Цель исследования – оценка эффективности и безопасности длительного приема винпоцетина (Кавинтон Комфорте) при лечении головокружения у пациентов с ХНМК.</p><sec><title>Пациенты и методы</title><p>Пациенты и методы. В открытом клиническом исследовании в параллельных группах приняли участие 139 пациентов. В 1-й группе (n=69) пациентам назначали винпоцетин (Кавинтон Комфорте) и вестибулярную гимнастику, во 2-й группе (n=70) – вестибулярную гимнастику. Эффективность лечения оценивали с помощью визуальной аналоговой шкалы головокружения (ВАШ-Г), шкалы влияния головокружения на повседневную активность (Dizziness Handicap Inventory, DHI), шкалы приверженности лечению (Drug Attitude Inventory, DAI), монреальской шкалы оценки когнитивных функций (Montreal Cognitive Assessment, МоСА), 5-балльной шкалы Лайкерта, а также видеонистагмографических тестов. Анализировали концентрацию нейротрофического фактора головного мозга (BDNF) в плазме крови до и после завершения лечения. Общая длительность исследования составила 8 мес (6 мес терапии и 2 мес наблюдения после ее отмены).</p></sec><sec><title>Результаты и обсуждение</title><p>Результаты и обсуждение. Применение винпоцетина значимо снизило субъективную выраженность головокружения (по шкале ВАШ-Г), а также улучшило повседневную активность больных (по шкале DHI) и ряд параметров по данным видеонистагмографических тестов – теста плавных следящих движений и исследования саккад. Динамика улучшения состояния больных по данным шкалы DНI значимо коррелировала с увеличением экспрессии BDNF в плазме крови в течение всего наблюдения (коэффициент корреляции Пирсона &gt;0,5). Применение винпоцетина позволило улучшить когнитивные функции больных (по тесту МоСА и 5-балльной шкале Лайкерта) и повысить приверженность проводимой терапии (по шкале DAI). Клинически значимый эффект улучшения статодинамической функции на фоне приема винпоцетина отмечался через 2 мес и был максимальным через 5 мес терапии, значимое улучшение когнитивных функций наблюдалось через 6 мес. Длительный прием винпоцетина не ассоциировался с риском развития серьезных нежелательных явлений.</p></sec><sec><title>Заключение</title><p>Заключение. Полученные результаты позволяют рекомендовать винпоцетин для длительного (не менее 5 мес) лечения головокружения и когнитивных нарушений (не менее 6 мес) у пациентов с ХНМК, при этом клинический эффект реализуется за счет стимуляции нейропластичности, в частности индукции синтеза BDNF.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>хроническая недостаточность мозгового кровообращения</kwd><kwd>головокружение</kwd><kwd>постуральная неустойчивость</kwd><kwd>винпоцетин (Кавинтон Комфорте)</kwd><kwd>нейротрофический фактор головного мозга</kwd><kwd>нейропластичность</kwd><kwd>безопасность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>chronic cerebrovascular insufficiency</kwd><kwd>dizziness</kwd><kwd>postural instability</kwd><kwd>vinpocetine (Cavinton Comforte)</kwd><kwd>brain-derived neurotrophic factor</kwd><kwd>neuroplasticity</kwd><kwd>safety</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">Barin K, Dodson EE.
