Myoclonic absence seizure of unknown (idiopathic) cause while standing

This boy demonstrated a variability of typical myoclonic absence seizure while standing: synchronous with the generalized spike-wave discharge, the upper part of his body, upper limbs, and right leg rhythmically jerk with concomitant unsteadiness, but he does not fall. During the event, the body slightly turned right and the head left. (Contributed by Dr Athanasios Covanis.)
