A Case of Reflex Epilepsy Induced by Higher Mental Activities, Mainly by Arithmetices

Abstract

We experienced a right handed case of reflex epilepsy induced by higher mental activity under a high mental tension, mainly by mental arithmetic and Soroban calculation.Clinical seizure induced by mental arithmetic was atypical absence without myoclonic jerk and that by Soroban calculation was myoclonic jerk on the right arm and fingers without loss of consciousness. On the EEG, a similar epileptic discharge which was generalized spike and wave discharge arising predominantly from left centro-parietal area occurred in both situations.
