Description: Brain surgeryBrain surgery to treat epilepsy can provide relief from seizures for up to 30 years, a new study suggests. "Few studies have looked at the long-term prognosis for epilepsy surgery," says researcher William H. Theodore, MD, of the National Institute of Neurological Disorders and Stroke, in a news release. "We found that 50 percent of the patients were free of seizures 30 years after the surgery."
