Epilepsy occurs in approximately 50 % of patients. A description of long-term follow-up of a patient with this syndrome and epilepsy in the form of development and epileptic encephalopathy with spike-wave activation in sleep is given. Epilepsy onset was at the age of 5 years with focal, bilateral tonic-clonic seizures and status epilepticus. On the electroencephalogram of nocturnal sleep, spike-wave activity was detected in the centrotemporal regions on both hemispheres, with an index of up to 100 %. The patient was able to choose antiepileptic therapy, a long-term remission was achieved, the seizures were stopped.</p></abstract><trans-abstract xml:lang="ru"><p>Представлена краткая литературная справка о редком генетическом синдроме Смит–Магенис, который проявляется умственной отсталостью, диссомнией и специфическими нарушениями поведения. Эпилепсия встречается примерно у 50 % пациентов. Авторы представляют описание многолетнего наблюдения за пациентом с синдромом Смит– Магенис и эпилепсией, проявляющейся в форме энцефалопатии развития и эпилептической со спайк-волновой активацией во сне. Эпилепсия дебютировала в возрасте 5 лет с фокальных приступов с переходом в билатеральные тонико-клонические приступы со статусным течением. На электроэнцефалограмме ночного сна выявлялась спайкволновая активность в центро-темпоральных отделах с обеих сторон, с индексом, достигающим 100 %. После подбора эффективной антиэпилептической терапии достигнута длительная ремиссия, приступы отсутствуют. Одновременно отмечается снижение индекса представленности эпилептиформной активности на электроэнцефалограмме. Нарушения развития, поведения и сна не претерпевали изменения в зависимости от тяжести течения эпилепсии (в том числе в активной фазе и в ремиссии эпилепсии).</p></trans-abstract><kwd-group xml:lang="en"><kwd>Smith–Magenis syndrome</kwd><kwd>17p11.2 deletion syndrome</kwd><kwd>RAI1 gene</kwd><kwd>epilepsy</kwd><kwd>sleep disorder</kwd><kwd>behavioral phenotype</kwd><kwd>videoelectroencephalographic monitoring</kwd><kwd>developmental and epileptic encephalopathies with spike-wave activation in sleep</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>синдром Смит–Магенис</kwd><kwd>синдром делеции 17p11.2</kwd><kwd>ген RAI1</kwd><kwd>эпилепсия</kwd><kwd>нарушение сна</kwd><kwd>поведенческий фенотип</kwd><kwd>видеоэлектроэнцефалографический мониторинг</kwd><kwd>энцефалопатия развития и эпилептическая со спайк-волновой активацией во сне</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Proposed Classification &amp; Definition of Epilepsy Syndromes 2021 with discussion.
