Abstract
-
Activation of epileptic seizure or electroencephalographic epileptiform discharges by mental calculation is rare, not reported in Korea. We report a 10-year-old right handed school girl without previous seizure history who showed clinically absence seizures and generalized synchronous 3 to 3.5Hz spike-and-wave dlscharges only when she attempted to perform difficult mental arithmetic. No further seizure was provoked after Valproic acid intake.
