Thus, it could be multifocal epilepsy with an extremely rapid, sometimes simultaneous, burning of the different foci, because of a very low convulsive threshold.

GEFS+ is an autosomal-dominant disorder in which the seizures start early and persist beyond 6 years of age. The prognosis is relatively benign without severe neurologic impairment.
