Epilepsy syndromes represent a specific set of seizure types and electroencephalographic and imaging features that tend to have age-dependent features, triggers, and prognosis. Epilepsy syndromes are the third and final level of epilepsy diagnosis, after classification of seizure and epilepsy types. Some epilepsy syndromes are self-limiting and pharmacoresponsive and others are pharmacoresistant and associated with poor developmental outcomes (epileptic and developmental encephalopathy). Features and management of 7 common age-dependent pediatric epilepsy syndromes are described.
