It is difficult to determine the nature of myoclonus without video electroencephalography (VEEG) monitoring.</p><sec><title>Objective</title><p>Objective: to present the clinical and electroencephalographic characteristics of new cases of benign nonepileptic myoclonus of infancy and early childhood.</p></sec><sec><title>Patients and methods</title><p>Patients and methods. The data of 33 children (19 boys and 14 girls) aged 5 months to 3 years with BNMI, who had been followed in 2011 to 2017, were analyzed.</p></sec><sec><title>Results and discussion</title><p>Results and discussion. The age at onset of paroxysms ranged from 4 to 24 months and that was 5–8 months in most cases. The most common movements were extensor muscle jerks (30.3%), head titubation with rotation (27.3%), axial spasms (27.3%), and nods (24.2%). The same child may have different types of paroxysms. Motor paroxysms were sporadic in all the patients and formed into clusters in 33.3% of cases. The frequency of clusters was up to 10 times daily. There were 2 to 50 paroxysms in the cluster. There was delayed psychomotor development in 5 of the 33 children and hyperexcitability was present in 10. VEEG monitoring indicated that the brain bioelectrical activity conformed to the age in 97% of cases; none of the children showed abnormal movements accompanied by EEG pathological activity. The duration of the disease was 2 to 19 months, averaging 7 months. In all cases paroxysms were stopped without using antiepileptic drugs.</p></sec></abstract><trans-abstract xml:lang="ru"><p>Синдром Феджермана – доброкачественный неэпилептический миоклонус младенчества (ДНММ) – редкий тип пароксизмальных состояний, имитирующий эпилептические спазмы. Без проведения электроэнцефалографии (ЭЭГ), в том числе видео-ЭЭГмониторинга (ВЭЭГ). сложно определить характер миоклонуса.</p><p>Цель исследования – представить клинико-электроэнцефалографическую характеристику новых случаев неэпилептического миоклонуса младенчества и раннего детства.</p><sec><title>Пациенты и методы</title><p>Пациенты и методы. Проанализированы данные 33 детей с ДНММ в возрасте от 5 мес до 3 лет (19 мальчиков и 14 девочек), наблюдавшихся с 2011 по 2017 г.</p></sec><sec><title>Результаты и обсуждение</title><p>Результаты и обсуждение. Возраст дебюта пароксизмов варьировался от 4 до 24 мес и в большинстве случаев составлял 5–8 мес. Наиболее частыми движениями являлись подергивания в разгибателях (30,3%), дрожание головы с ротацией (27,3%), аксиальные спазмы (27,3%) и кивки (24,2%). У одного ребенка могли встречаться различные виды пароксизмов. Двигательные пароксизмы были единичными у всех пациентов и формировались в кластеры в 33,3% случаев. Частота кластеров – до 10 раз в сутки. Количество пароксизмов в кластере – от 2 до 50. Задержка психомоторного развития наблюдалась у 5 из 33 детей, синдром гипервозбудимости – у 10. При ВЭЭГ биоэлектрическая активность мозга соответствовала возрасту в 97% случаев, ни у одного ребенка двигательные пароксизмы не сопровождались патологической активностью на электроэнцефалограммах. Длительность заболевания составляла от 2 до 19 мес, в среднем – 7 мес. У всех пациентов пароксизмы купировались без применения антиэпилептических препаратов.</p></sec><sec><title>Заключение</title><p>Заключение. Своевременное распознавание ДНММ крайне важно, так как в случаях ошибочного диагноза возможно необоснованное назначение антиэпилептической терапии. Решающую роль в диагностике неэпилептического и эпилептического миоклонуса играет ВЭЭГ.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>доброкачественный неэпилептический миоклонус младенчества и раннего детства</kwd><kwd>синдром Феджермана</kwd></kwd-group><kwd-group xml:lang="en"><kwd>benign nonepileptic myoclonus of infancy and early childhood</kwd><kwd>Fejerman syndrome</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">Shibaki H, Hallet M.
