Definition of awake brain surgery
Awake brain surgery is a type of procedure performed while you’re awake to treat some brain (neurological) conditions, including some brain tumors or epileptic seizures.
If your tumor or seizure center (epilepsy focus) is near the parts of your brain that control vision, movement or speech, you may be awake during surgery to respond to your surgeon.
Your responses help your surgeon to ensure that he or she treats the precise area of your brain needing surgery. In addition, the procedure lowers the risk of damage to functional areas of your brain.
