According to neuroimaging data, in patients with hemichorea/hemiballismus, the foci were located in the anterior parts of the corona radiata in the projection of the descending pathways from the cortex to the striatum and in the putamen. In a patient with spastic torticollis, the focus was in the thalamus. In a patient with recurrent myoclonic hyperkinesis, no changes in perfusion (CBV and Tmax) were found during hyperkinesis, but computed tomography revealed post-stroke cysts in the right somatosensory area and in the right hemisphere of the cerebellum.</p><p>The occurrence of HM may be caused not only by structural changes, but also by functional disorders of the neural networks involved in the integration of motor activity.</p></abstract><trans-abstract xml:lang="ru"><p>Гиперкинезы как единственный или ведущий синдром в дебюте острых нарушений мозгового кровообращения (ОНМК) наблюдаются менее чем в 1% случаев ОНМК и могут приводить к диагностическим сложностям, нарушая маршрутизацию и откладывая проведение реперфузионной терапии.</p><p>Приведены четыре наблюдения: два – с острым развитием гемихореи/гемибаллизма и по одному – с повторными преходящими эпизодами миоклонии и со спастической кривошеей. По данным нейровизуализации, у пациентов с гемихореей/гемибаллизмом очаги локализовались в передних отделах лучистого венца в проекции нисходящих путей от коры к полосатому телу и в скорлупе. У пациента со спастической кривошеей очаг был в зрительном бугре. У пациента с повторяющимся миоклоническим гиперкинезом изменений перфузии (CBV и Tmax) во время гиперкинеза не установлено, но при компьютерной томографии выявлены постинсультные кисты в правой соматосенсорной области и в правом полушарии мозжечка.</p><p>Возникновение гиперкинезов может быть обусловлено не только структурными изменениями, но и функциональным нарушением нейронных сетей, участвующих в интеграции двигательного акта.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>инсульт</kwd><kwd>экстрапирамидная система</kwd><kwd>гиперкинезы</kwd><kwd>хорея</kwd><kwd>баллизм</kwd><kwd>миоклония</kwd><kwd>спастическая кривошея</kwd><kwd>нейронные сети</kwd></kwd-group><kwd-group xml:lang="en"><kwd>stroke</kwd><kwd>extrapyramidal system</kwd><kwd>hyperkinesis</kwd><kwd>chorea</kwd><kwd>ballism</kwd><kwd>myoclonus</kwd><kwd>spastic torticollis</kwd><kwd>neural networks</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование не имело спонсорской поддержки</funding-statement><funding-statement xml:lang="en">The investigation has not been sponsored</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Edlow JA, Selim MH.
