Abstract
Benign occipital epilepsy is a newly recognized form of partial epilepsy in children. It is characterized by motor seizures preceded in some cases by visual symptoms and a relatively benign course. We present three siblings with this condition and a fourth with the EEG abnormalities. A family study including 25 relatives demonstrated a typical EEG abnormality in 26% of relatives. These EEG changes were more evident in younger members. These findings suggest an autosomal dominant pattern for the EEG abnormalities with age-dependent expression and variable penetrance of the seizure disorder.
