Asymptomatic generalized discharges in epilepsy with GTCS alone (video-EEG)

Generalized discharges of 3 to 4 Hz spike/polyspike-wave in a patient with epilepsy with GTCS alone. There were not any clinical manifestations during these discharges, and breath-counting during hyperventilation was entirely undisturbed. Note that the discharges may start from right or left. Also note focal spikes at various locations. (Modified with permission from: Panayiotopoulos CP. A clinical guide to epileptic syndromes and their treatment. Rev. 2nd ed. London: Springer, 2010.)
