Eating Epilepsy Characterized by Periodic Spasms

Abstract

Seizures induced by eating are generally considered rare. Eating epilepsy is a kind of reflex epilepsy. We report two patients aged 11 and 16, with seizures provoked by eating. The eating-provoked seizures in both patients were a series of tonic spasms. Both ictal EEGs showed a periodic pattern characterized by diffuse high voltage slow wave. These findings were consistent with periodic spasms described by Gobbi et al. The ECD were widely distributed in both patients, although that of Patient 1 was partially clustered in the right frontal region. This is the first report of patients with periodic spasms induced by eating.
