In case of some epileptic syndromes seizures occur predominantly or solely in sleep. Epilepsy can modify normal sleep patterns; on the other hand, sleep influences interictal epileptiform discharges, increasing their number and changing their morphology and spreading depending on sleep stage. Although interictal discharges in focal epilepsy are more common in sleep than in wakefulness, discharge distribution in generalized epilepsy is more variable. For some epileptic syndromes there is a strong correlation between time of onset, frequency, severity of attacks and stage of sleep cycle or wakefulness. Further research in this area can shed light not only on mechanisms of epileptic networks functioning, but also on the sleep-wake cycle regulatory systems.</p></abstract><trans-abstract xml:lang="ru"><p>Настоящий обзор посвящен взаимосвязи между клинико-электрофизиологическими проявлениями различных форм эпилепсии и уровнем бодрствования, глубиной сна. При некоторых эпилептических синдромах приступы возникают преимущественно или исключительно во сне. Многочисленные данные свидетельствуют о том, что эпилепсия может модифицировать нормальные паттерны сна. С другой стороны, сон влияет на интериктальную эпилептиформную активность, усиливая ее, а также изменяя морфологию и распространение разрядов в зависимости от глубины сна. Если для фокальной эпилепсии характерно нарастание интериктальной активности во сне, то при генерализованных формах паттерны распределения во время сна и бодрствования более разнообразны, что отражает, вероятно, различия в патофизиологических механизмах этих эпилептических феноменов. Дальнейшие исследования могут пролить свет на механизмы формирования эпилептических нейрональных сетей, а также характер их взаимосвязи с функционированием систем, регулирующих цикл сон–бодрствование.</p></trans-abstract><kwd-group xml:lang="en"><kwd>epilepsy</kwd><kwd>sleep</kwd><kwd>electroencephalography</kwd><kwd>epileptic seizures</kwd><kwd>sleep stages</kwd><kwd>cyclic alternating patterns</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>эпилепсия</kwd><kwd>сон</kwd><kwd>электроэнцефалография</kwd><kwd>эпилептические приступы</kwd><kwd>стадии сна</kwd><kwd>циклические альтернирующие паттерны</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Carreño M., Fernández S.
