Benign familial infantile epilepsy.

We report 23 subjects with afebrile seizures. The subjects, from 11 families, were between the ages of 3 and 19 months and had normal neurodevelopmental status, a normal interictal electroencephalogram, a family history of similar seizures, and an excellent prognosis. Benign familial infantile epilepsy is a clinical syndrome that may be more common than is presently recognized.
