Spontaneous, eye-closure, and IPS-induced generalized discharges associated with myoclonic jerks

A girl aged 15 years with Jeavons syndrome had epileptic seizures that were spontaneous or elicited by eye closure and photic stimulation. Ictal clinical manifestations consist of eyelid myoclonia with or without jerks of the hands, head, and eyelids. Cognition was usually intact or only slightly impaired during the discharges. Ictal EEG manifested with frequent generalized discharges of spike or multiple spikes and slow waves, mainly on eye closure and intermittent photic stimulation.
