Concomitance of Childhood Absence Epilepsy and Benign Rolandic Spikes / 대한간질학회지

ABSTRACT

Childhood absence epilepsy (CAE) and benign epilepsy of childhood with centro-temporal spikes (BECT) are common forms of idiopathic epilepsy of childhood onset and share many features such as the marked age dependence of onset. The occurrence of generalized 3 Hz spike and waves in BECT or rolandic spikes in CAE has rarely been reported. We report 2 cases of concomitance of CAE and benign rolandic spikes. All of the two patients were female and had clinically absence seizure only. On EEG the two patients simultaneously showed centro-temporal spikes as well as ictal onset of absence seizure consisting of generalized 3 Hz spike and waves. All of the two patients have become seizure-free with valporic acid. It is rare but not impossible that (Rolandic spikes can concur with CAE rather than as a continuum between CAE and BECT), because all of the two patients have not shown BECT so far.
