Idiopathic Generalized Epilepsy Syndromes

The idiopathic generalized epilepsies (IGEs) have historically included the syndromes childhood absence epilepsy (CAE), juvenile absence epilepsy (JAE), juvenile myoclonic epilepsy (JME), and epilepsy with generalized tonic-clonic seizures alone (GTCA). Recognition of the IGEs is important for clinical care, as it informs diagnosis, prevents unnecessary investigation, allows optimal selection of anti-seizure medications (ASMs), and provides prognostic guidance. According to the new ILAE definition in 2022, the study aims to describe the clinical features, electroencephalographic, imaging findings and long-term prognosis.
