We present the clinical case of the patient with generalized seizures. Routine electroencephalography (EEG) data registered diffuse epileptiform activity that allowed to diagnose genetic  eneralized epilepsy and pharmacoresistant course of seizures.After performing magnetic resonance imaging using the epileptological program and video-EEG-monitoring, the diagnosis was revised: structural focal epilepsy with seizures with  focal onset with oroalimentary, gesture automatisms in the right hand, bilateral tonic-clonic, uncompensated by levetiracetam monotherapy (1500 mg/day). Background disease: congenital  malformation of the brain: FCD in the basal parts of the left temporal lobe. Lacosamide was added to the therapy in the drug dose 300 mg/day, and the frequency of epileptic seizures decreased. Differential diagnosis between genetic generalized  epilepsy and structural epilepsy with FCD usually poses no  obstacles. However, in some cases, structural epilepsy occurs  under the “mask” of generalized epilepsy. Hence, this clinical  case demonstrates the importance of diagnostic measures in the  differential diagnostics of various forms of epilepsy to determine  further tactics of patient management. </p></abstract><trans-abstract xml:lang="ru"><p>Фокальная кортикальная дисплазия (ФКД) в течение последних лет признана одной из наиболее распространенных патологий, лежащих в основе  фармакорезистентных структурных эпилепсий. Мы  представляем клиническое наблюдение пациента с  генерализованными судорожными приступами. По данным  рутинных электроэнцефалографий (ЭЭГ) регистрировалась  диффузная эпилептиформная активность, что привело к постановке диагноза генетической генерализованной  эпилепсии с фармакорезистентным течением приступов.После выполнения магнитно-резонансного томографического исследования по эпилептологической  программе и видео-ЭЭГ-мониторинга диагноз был  пересмотрен: структурная фокальная эпилепсия с приступами  с фокальным началом с ороалиментарными,  жестовыми автоматизмами в правой руке, билатеральными тоникоклоническими, не компенсированными на фоне монотерапии леветирацетамом 1500 мг/сут. Фоновое заболевание: врожденный порок развития головного мозга –  ФКД в базальных отделах левой височной доли. Проведена коррекция противоэпилептической терапии: добавлен лакосамид 300 мг/сут, после чего частота эпилептических приступов уменьшилась. Дифференциальный диагноз между генетической генерализованной эпилепсией и структурной эпилепсией на фоне ФКД, как правило, не представляет трудностей. Однако в отдельных случаях структурная  эпилепсия протекает под «маской» генерализованной эпилепсии. Представленный нами клинический случай демонстрирует значимость диагностических мероприятий в проведении дифференциальной диагностики различных форм эпилепсии для определения дальнейшей тактики ведения пациента.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Фокальная кортикальная дисплазия</kwd><kwd>магнитно-резонансная томография</kwd><kwd>видео-ЭЭГ-мониторинг</kwd><kwd>генерализо- ванные судорожные приступы</kwd><kwd>генерализованная эпилептиформная активность.</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Focal cortical dysplasia</kwd><kwd>magnetic resonance imaging</kwd><kwd>video-EEG monitoring</kwd><kwd>generalized seizures</kwd><kwd>generalized epileptiform activity</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">Epitashvili N., San Antonio-Arce V., Brandt A., Schulze-Bonhage А.
