Ictal characteristics of cryptogenic partial epilepsies in infancy.
Twenty-three patients with onset of partial seizures (PS) during the first 2 years of life were collected in a single neuropediatric center and ictal events were analyzed. All patients initially had normal developmental and neurologic examinations, negative etiologic investigations, and at least two nonfebrile PS of a single type. Mean follow-up from first seizure to the last contact with the patient was 51 months (SEM 8.17 months). Ictal semiology was characterized by three types of seizures: simple PS with motor signs, complex partial seizures (CPS) with impairment of consciousness at onset followed by motor manifestations, and CPS with motor activity at onset. Versive phenomena, oroalimentary automatisms, and vegetative manifestations were frequently associated. The topography of the ictal discharges and the elementary ictal events, suggested involvement of the temporal lobe and somatomotor area. The diagnosis of PS can be difficult during the first year of life since some patients beginning with generalized seizures may evolve into partial seizures. The prognosis is guarded with regard to seizure persistence, but the neurologic outcome is better as a whole than is reported for infancy-onset epilepsies.
