Epilepsy that causes generalized seizures is more common in children than in adults. Partial seizures start in a specific, often damaged area in the brain. But generalized seizures can't be traced to a specific location or focus. The abnormal electrical activity that causes the seizures begins over the entire surface of the brain. And these seizures tend to affect the entire body.
Epilepsy that causes these seizures may have no known cause (idiopathic). Or it may be caused by another condition (symptomatic). It is most often treated with medicine. But surgery may help in some cases.
Benign rolandic epilepsy is one form of epilepsy. With this condition, seizures affect the face and sometimes the body. As a result, the disorder causes problems for some children. It almost always disappears, though, by adolescence.
