title: Landau-Kleffner syndrome responsive to levetiracetam.
abstract: A 5-year-old girl with Landau-Kleffner syndrome is discussed. The child began having seizures at age 4 associated with language deterioration despite anticonvulsant therapy. With levetiracetam monotherapy to a dose of 60 mg/kg/day and discontinuation of carbamazepine and valproic acid, her language has improved and seizures are controlled. Levetiracetam should be considered as therapy for Landau-Kleffner syndrome.
