Idiopathic generalized epilepsies (EIG) are the most common types of epilepsy in childhood and adolescence. Based on the main seizure type and age at onset, four classic subsyndromes exist: childhood absence epilepsy, juvenile absence epilepsy, juvenile myoclonic epilepsy, and epilepsy with generalized tonic-clonic seizures alone. Although autosomal dominant inheritance occurs in rare families, clinical genetic data indicate that complex inheritance involving two or more genes is likely in the majority of families.
The International League Against Epilepsy (ILAE) Commission on Classification and Terminology has revised concepts, terminology, and approaches for classifying seizures and forms of epilepsy. Genetic, structural-metabolic, and unknown represent modified concepts to replace idiopathic, symptomatic, and cryptogenic.
