Abstract

Childhood Absence Epilepsy(CAE) and Benign Epilepsy of Childhood with Centrotemporal Spikes(BECTS, Rolandic Epilepsy) are the most common forms of epilepsy occurring in previously neurologically normal children. Both epilepsy syndromes appear in the first decade of life and their prognosis is ususally good. The EEG of CAE typically has generalized synchronous 3/sec spike and wave complexes as a sign of generalized hyperexcitability of the cortex. The BECTS shows centrotemporal foci as a sign of hyperexcitability of the motor cortex. A concomitance of these two epilepsy syndromes in a patient is very rare, and has not been frequently reported. We experienced a 5 year old boy who had absence seizure, with EEG features of centrotemporal spikes. The first EEG showed generalized synchronous 3/sec spike and wave complexes at the age of 5, and the follow-up EEG showed centrotemporal spikes. We report a case of CAE, which showed features of centrotemporal spikes in the follow-up EEG.
