Patients
Our cohort comprised 125 individuals: 100 with JME, 10 with juvenile absence epilepsy (JAE), 7 with GTCS on awakening, 3 with childhood absence epilepsy (CAE), and 5 with unclassified GGE. These patients were regularly followed in the outpatient epilepsy clinic of the university hospitals at the University of Campinas and the Federal University of Alagoas, Brazil. They fulfilled the clinical criteria for GGEs, according to the International League Against Epilepsy (ILAE) guidelines (Fisher et al., 2017; Scheffer et al., 2017; Wilmshurst et al., 2015). Clinical and demographic features of these patients have been previously published (Betting et al., 2006; Gitai et al., 2012).
