Benign focal epilepsy of childhood. A follow-up study of 100 recovered patients.

Benign focal epilepsy of childhood is an entity that includes characteristic clinical and electroencephalographic manifestations. Clinically, it consists of typical brief, hemifacial seizures that tend to become generalized when they occur nocturnally. The EEG findings include slow, diphasic, high-voltage, centro-temporal spikes, often followed by slow waves. Retrospective and prospective studies were carried out on 100 such patients, all of whom recovered before reaching adulthood, with the disappearance of both the clinical manifestations and the EEG findings.
