Abstract
Until relatively recently, genetic influences in partial seizures were thought to be of minimal importance. However, with further identification of childhood benign partial seizures it is becoming clear that inheritance plays a major role in the pathogenesis of these seizures. Diagnostic criteria proposed for benign partial seizures include absence of neurologic or intellectual deficits, family history of epilepsy, onset of seizures after age 2 years, stereotyped brief seizures, frequent nocturnal occurrence, spontaneous remission in adolescence, and electroencephalograms (EEGs) demonstrating spikes with a distinctive morphology and localization superimposed on normal background activity. The two most commonly described benign partial epilepsies of childhood are benign Rolandic epilepsy (BRE) and benign occipital epilepsy (BOE). Both disorders begin in childhood, are associated with characteristic EEG patterns, have seizures that are easily controlled with medication, often are familial, and have an excellent prognosis. The other benign partial seizure disorders in children that have been described are not as well studied as BOE and BRE, and the role of inheritance pattern, if any, is less clear.
