Overview

Epilepsy surgery is a procedure that removes or alters an area of your brain where seizures originate.

Epilepsy surgery is most effective when seizures always originate in a single location in the brain. Epilepsy surgery is not the first line of treatment but is considered when at least two anti-seizure medications have failed to control seizures.

A number of pre-surgical assessments are necessary to determine whether you’re eligible for epilepsy surgery and how the procedure is performed.

Why it’s done

Epilepsy surgery may be an option when medications do not control seizures, a condition known as medically refractory epilepsy or drug-resistant epilepsy. The goal of epilepsy surgery is to eliminate seizures or limit their severity with or without the use of medications.

Poorly controlled epilepsy can result in a number of complications and health risks, including the following:

  • Physical injuries during a seizure
  • Drowning, if the seizure occurs during a bath or swimming
  • Depression and anxiety
  • Decline in memory or other thinking skills
  • Developmental delays in children
  • Sudden death, a rare complication of epilepsy
