Generalized spike-wave complexes at electroencephalography have been also described as an obligatory symptom. The Unverricht-Lundborg disease is a distinct entity within the group with specific age at manifestation (7 to 13 years), as well as slow cognitive and motor decline with stabilization in the adult age. In 90% of the cases, the diagnosis is confirmed by identification of the expanded nucleotide duplicates in the CSTB gene. An adequately tailored anticonvulsant treatment can stabilize and improve the patient's condition. The anticonvulsant therapy should not include sodium channel blockers. Valproate sodium is considered to be the main agent; it is usually combined with levetiracetam/zonisamide/topiramate/benzodiazepins. In the recent years, perampanel has been also used as a part of the combination treatment.</p></abstract><trans-abstract xml:lang="ru"><p>Синдром прогрессирующих миоклонус-эпилепсий – гетерогенная группа генетических заболеваний, для которых характерны миоклонус, прогрессирующие двигательные и когнитивные нарушения, сенсорные и мозжечковые симптомы, аномальное замедление основной биоэлектрической активности на электроэнцефалограмме, нормальные когнитивные функции и нормальное развитие пациента до начала заболевания. Как облигатный симптом также описываются генерализованные спайк-волновые разряды на электроэнцефалограмме. Болезнь Унферрихта – Лундборга выделяется из этой группы по возрасту дебюта заболевания (от 7 до 13 лет), медленному когнитивному и двигательному регрессу со стабилизацией во взрослом возрасте. Диагноз в 90% всех случаев подтверждается обнаружением экспансии нуклеотидных повторов в гене CSTB. Адекватно подобранная противосудорожная терапия может стабилизировать и улучшить состояние пациента. В противосудорожном лечении следует воздерживаться от назначения блокаторов натриевых препаратов. Базовым препаратом считается вальпроат натрия, который обычно комбинируется с леветирацетамом/зонисамидом/топираматом/бензодиазепинами. В последние годы в комбинированной терапии используется и перампанел.</p></trans-abstract><kwd-group xml:lang="en"><kwd>progressive myoclonic epilepsies</kwd><kwd>diagnostic criteria</kwd><kwd>Unverricht-Lundborg disease</kwd><kwd>anticonvulsant treatment</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>прогрессирующие миоклонус-эпилепсии</kwd><kwd>диагностические критерии</kwd><kwd>болезнь Унферрихта – Лундборга</kwd><kwd>противосудорожная терапия</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Riney K, Bogacz A, Somerville E, Hirsch E, Nabbout R, Scheffer IE, Zuberi SM, Alsaadi T, Jain S, French J, Specchio N, Trinka E, Wiebe S, Auvin S, Cabral-Lim L, Naidoo A, Perucca E, Moshé SL, Wirrell EC, Tinuper P.
