Myoclonic absence seizure of idiopathic (unknown) cause (1)

The video-EEG recorded typical myoclonic absence seizures in this 11-year-old boy. Notice that during hyperventilation, his head bends down, his eyes open, and there is no response to verbal command, concomitant with rhythmic upward jerking of upper limbs during the generalized spike-wave discharge. Seizure onset was at 12 months old. (Contributed by Dr. Athanasios Covanis.)
