Epilepsy surgery : Epilepsy surgery is a treatment option for patients with epilepsy who do not respond to medication or who experience severe, uncontrolled seizures. The goal of surgery is to remove or alter the brain tissue where seizures originate, thereby reducing or eliminating seizure activity. Types of epilepsy surgery include resection, where the area of the brain responsible for seizures is surgically removed, and disconnective procedures, which involve cutting connections between the seizure focus and other brain areas. Candidates for epilepsy surgery typically undergo extensive evaluation, including brain imaging and electroencephalography (EEG), to determine the precise location of seizure activity. Successful surgery can significantly improve quality of life and seizure control for many patients.
