Restless legs with antiepileptic drug therapy.
The restless legs syndrome is generally benign but is occasionally associated with anemia, metabolic disorder, or polyneuropathy. Leg restlessness with disruptive nocturnal myoclonus has been described as a sleep disorder. We report two patients with complex partial and secondarily generalized seizures, who developed restless legs while taking methsuximide and phenytoin. They had no evidence of metabolic disturbance or neuromuscular disease, although one patient had fragmented sleep and disruptive myoclonus on polysomnography, and leg restlessness subsided with change of antiepileptic drugs. These symptoms could reflect transient alteration in peripheral nerve function not evident by examination or electrophysiologic studies, sleep disturbance by antiepileptic drugs or the effects of temporal lobe seizure foci on perception of the physiologic state of nerves and muscles.
