What are risks of epilepsy surgery?

Several types of brain surgery can prevent or reduce epileptic seizures. Operations can carry risks, like:

If you have a seizure right after surgery, your doctor may suggest a second surgery. It usually isn’t a sign of failure, but that your surgeon didn’t remove all the brain tissue that causes seizures.

• Infection and bleeding, as well as the chance of an allergic reaction to the anesthesia.
• Making existing problems worse or creating new problems with your brain. You could lose vision, speech, memory, or movement.
• A return of seizures.
