Infantile epilepsy with occipital focus and good prognosis.

The authors studied 18 cases of infantile epilepsy with occipital focus and good prognosis. The patients were selected according to clinical and EEG criteria. Those criteria are: neurological and neuroradiological examinations must not show any abnormality; the patients must be free from seizures for at least 3 years and 6 months; the fundamental EEG activities must be normal, and a spike and/or spike and wave occipital focus has to be present. The medical story, the clinical and EEG follow-up, the seizures semiology (clinical and EEG) during the awake and sleep stages are described. The data show a new primary benign epileptic entity which is probably associated to maturation disturbances.
