Narcolepsy is a chronic disease that causes excessive daytime sleepiness. Some narcolepsy symptoms, especially cataplexy, can be mistakenly interpreted as epileptic seizures. The clinical case demonstrates an importance for interdisciplinary approach to differential diagnosis of epileptic seizures. Clinical markers of typical and atypical cataplexy manifestations are presented.</p></abstract><trans-abstract xml:lang="ru"><p>Особенную сложность на приеме врача-невролога представляет дифференциальная диагностика эпилептических и неэпилептических пароксизмов. Нарколепсия – это хроническое заболевание, одним из проявлений которого является чрезмерная дневная сонливость. Некоторые симптомы нарколепсии, особенно катаплексия, могут быть очень похожи на эпилептические приступы. Представленное наблюдение демонстрирует важность междисциплинарного подхода при проведении дифференциальной диагностики эпилептических приступов. Приведены клинические маркеры типичных и атипичных проявлений катаплексии, критерии диагностики нарколепсии.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Эпилепсия</kwd><kwd>нарколепсия</kwd><kwd>катаплексия</kwd><kwd>потеря мышечного тонуса</kwd><kwd>диагностика</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Epilepsy</kwd><kwd>narcolepsy</kwd><kwd>cataplexy</kwd><kwd>loss of muscle tone</kwd><kwd>diagnosis</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">Dmitrenko D.V., Strotskaya I.G., Artyukhov I.P., et al.
