When the doctor has made a diagnosis of seizures or epilepsy, the next step is to select the best form of treatment. If the seizure was caused by an underlying correctable brain condition, surgery may stop seizures. If epilepsy -- that is, a continuing tendency to have seizures -- is diagnosed, the doctor will usually prescribe regular use of seizure-preventing drugs. If drugs are not successful, other methods may be tried, including surgery, a special diet or vagus nerve stimulation (VNS). The goal of all epilepsy treatment is to prevent further seizures, avoid side effects, and make it possible for people to lead active lives.
