Carbamazepine responsive epileptic oral motor and ocular motor apraxia

We evaluated seven patients with oral motor apraxia and ocular motor apraxia. Apraxia in three patients (Group 1) with new-onset partial seizures and epileptiform discharges on EEG improved with carbamazepine. Four patients (Group 2) without seizures and nonepileptiform EEG findings had no change in apraxia after a trial of carbamazepine. Epileptic apraxia may precede clinical seizures and can respond to antiepileptic drugs.
