Epilepsy is a common phenotypic sign of both syndromic and non-syndromic mitochondrial diseases. Epilepsy in mitochondrial diseases is poorly treatable and is often an unfavorable prognostic sign. Patients with mitochondrial epilepsy are prescribed various anti-seizure medications. Mitochondriotoxic drugs should be avoided. Descriptions of MELAS-syndrome, MERRF-syndrome, Leigh-syndrome, NARP-syndrome are given.</p></abstract><trans-abstract xml:lang="ru"><p>   При дисфункции митохондрий преимущественно поражаются органы с высокой метаболической потребностью, в первую очередь – головной мозг. Эпилепсия является распространенным фенотипическим признаком как синдромных, так и несиндромных митохондриальных заболеваний. Эпилепсия при митохондриальных заболеваниях плохо поддается лечению и часто является неблагоприятным прогностическим признаком. Пациентам с митохондриальной эпилепсией назначают различные антиэпилептические препараты, однако следует избегать митохондриотоксичных препаратов. Представлены описания синдромов MELAS, MERRF, Leigh и NARP.</p></trans-abstract><kwd-group xml:lang="en"><kwd>epilepsy</kwd><kwd>seizure</kwd><kwd>mitochondria</kwd><kwd>MELAS</kwd><kwd>MERRF</kwd><kwd>Leigh</kwd><kwd>NARP</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>эпилепсия</kwd><kwd>эпилептический приступ</kwd><kwd>митохондрии</kwd><kwd>MELAS</kwd><kwd>MERRF</kwd><kwd>Leigh</kwd><kwd>NARP</kwd></kwd-group><funding-group><funding-statement xml:lang="en">The work was performed without external funding</funding-statement><funding-statement xml:lang="ru">Работа выполнена без спонсорской поддержки</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Batysheva T.
