Selective epileptic gait disorder.

Two children with an unusual gait disorder, one combined with acquired aphasia, in association with focal epilepsy are reported. Both children also showed paroxysmal "dystonic" phenomena, and a clear therapeutic response to corticosteroids. This newly described condition widens the range of discrete, recoverable defects of cerebral function that are associated with epilepsy in the developing nervous system and suggests that the site of action is at a functionally combined bilateral motor/sensory level of the cerebral cortex.
