Eight individuals in two generations of a family experienced seizures neonatally or in early infancy. Evaluation in two of these infants documented an EEG pattern suggestive of seizure activity without discernible pathogenesis of their seizures. Subsequently, affected individuals had a normal neurodevelopmental outcome, although one person had later epilepsy. The benign course of this disorder and its association with adult epilepsy agree with previously reported cases from the literature.
