TY - CHAP M1 - Book, Section TI - Etiologies of Epilepsy A1 - Coorg, Rohini A2 - Kline, Mark W. Y1 - 2018 N1 - T2 - Rudolph's Pediatrics, 23e AB - Epilepsy is not a single disease. Epilepsy may represent a primary disorder, often with an identified genetic cause, or it may be a symptom or result of another disease. Understanding the etiology of a patient’s epilepsy has important implications for management and prognosis. In 1989, the International League Against Epilepsy (ILAE) classified etiologies of epilepsy into 3 main categories: symptomatic, cryptogenic, and idiopathic. In 2010, the ILAE reorganized the epilepsies into having a structural/metabolic (previously “symptomatic”), unknown (previously “cryptogenic”), or genetic (previously “idiopathic”) cause. The ILAE classification systems of epilepsy are discussed in more detail in Chapter 549.
