Myoclonic absence seizures of a boy with normal development (idiopathic)

Video-EEG at eight years of age showed numerous spontaneous and hyperventilation-induced typical absence seizures. These were characterized by rhythmic myoclonic jerks of the head and arms, though in all other respects, such as impairment of consciousness, opening of the eyes, and automatisms, were similar to those of childhood absence epilepsy. In addition, some absences occurred during sleep and were again characterized by rhythmic myoclonic jerks. There were no differences between absences occurring in wakefulness or sleep.
