Myoclonic absence seizures of the syndrome epilepsy with myoclonic absences (EEG) (2)

The typical myoclonic absence episodes were recorded during video-EEG recordings in an 11-year-old boy when he was assessed following the relapse of three generalized tonic-clonic seizures. During hyperventilation, his head bent down with eyes open, and there was no response to verbal command. The upper limbs jerked rhythmically upward during the generalized spike-wave discharge. Neurologic assessment revealed no lateralizing signs, and the MRI was negative. The episodes were controlled by 80% with a combination of sodium valproate and ethosuximide at optimal daily doses. The family and patient history were noncontributory. (Contributed by Dr. Athanasios Covanis.)
