Malignant migrating partial seizures in a 4‐month‐old boy

ABSTRACT Malignant migrating partial seizures in infancy is an epilepsy syndrome characterised by an onset before the age of six months, multifocal seizures and an EEG pattern consisting of seizures which occur independently and sequentially from both hemispheres. The clinical course of a four‐month‐old boy with this syndrome, illustrated by video material of the seizures and EEG recordings, is described. The possible neurophysiological mechanism of epileptogenic activity alternating or ‘migrating’ from one hemisphere to the other is discussed.
