Myoclonic absence seizures of structural cause

Myoclonic absence seizures of structural cause (video-EEG)

Video EEG recorded typical myoclonic absence seizures in a patient aged 15 months. Clinically, there were rhythmic and symmetrical violent myoclonic jerks, mainly of the arms, coinciding with the multiple spike components. Note the regular 3.5-Hz multiple spike-and-slow wave discharge smoothly slowing down to 2.5 Hz. There is also a discharge discontinuation that is rare in childhood absence epilepsy.
