[Other infant epilepsies beyond the West and Lennox-Gastaut syndromes (author's transl)].

The clinical manifestations and the classification of the epilepsies of infants are briefly reviewed. 207 cases were classified status epilepticus (51 cases), brief partial seizures (57 cases), and brief generalized seizures (99 cases). Lesional factors, especially brain malformations, play a major role in the aetiology, but the importance of genetic factors is suggested by the presence of a positive family history of convulsive disorders in 25% of the cases. The mental and neurological prognosis is grave, as only 22% of the patients developed normally. The prognosis varies with the aetiology of the epilepsies and appears more favorable when familial antecedents of convulsive disorders are present.
