Late-Onset Generalized Myoclonic Seizure: Case Report

Abstract

Most of the epileptic seizures that begin at an advanced age are focal onset seizures due to an underlying structural lesion. Generalized myoclonic seizures, usually seen in adolescence, are very rare in elderly patients without a history of epilepsy. In this study, we present a 60-year-old patient with generalized myoclonic seizures with electrophysiological findings. Because of the late-onset, myoclonic jerks were first evaluated with the diagnosis of non-epileptic psychogenic attack in an external health center. The patient was diagnosed with seizure recordings in Electroencephalography-video monitoring. The patient responded well to the antiepileptic treatment and became seizure-free.
