Abstract:
Zonisamide (ZNS) has been proven as a safe, effective, and well-tolerated antiepileptic drug. We report an epilepsy patient who had a severe, dose-dependent, memory deficit after ZNS administration. A 65-year-old man visited our epilepsy clinic due to the occurrence of nocturnal convulsions. Despite the absence of seizures, he developed a severe impairment of verbal and visual memory functions after the increment of ZNS dosage from 200 mg/day to 300 mg/day. We substituted 1,000 mg/day valproic acid for ZNS. His cognitive performances were returned to original levels.
