Focal Electroencephalographic Abnormalities in Juvenile Myoclonic Epilepsy

Abstract

A detailed study of EEGs of patients with an unequivocal diagnosis of juvenile myoclonic epilepsy (JME) showed a high prevalence of focal EEG abnormalities. Focal slow waves, spikes, and sharp waves and focal onset of the generalized discharge were present in 36.7% of EEGs in our patients with JME. In more than half of the patients, at least one EEG showed focal abnormalities. These features should not be misconstrued as indicative of partial epilepsy.
