Types of Brain Surgery for Epilepsy
More than three million people in the U.S. suffer from epilepsy, according to the Centers for Disease Control and Prevention. About one-third of people with epilepsy don't respond to medications used to treat seizures. For those people, surgery may be an option to eliminate or reduce seizures in the future.
There are two types of epilepsy surgery:
- Traditional or "open" surgeries that require manually removing the portion of the brain causing seizures. The most common is a resection, which removes part of the temporal lobe (the section of the brain involved in vision, memory, language, comprehension, and more).
- Minimally invasive surgeries that do not require opening the skull such as laser ablation. Other minimally invasive options that do not involve brain surgery, but use neurostimulation device implantations include:
Choosing the Best Epilepsy Surgery for You
If you and your doctor have decided that surgery is the best treatment for your epilepsy, your doctor will discuss your options based on the following factors:
- where the seizures occur in your brain,
- how well you respond to treatment, and
- many other factors.
It is safe for both adults and children to have brain surgery for seizures. Your doctor will help you understand any additional risks for children and may not recommend surgery until your child reaches a certain age.
Preparing for Surgery
To prepare for surgery, your doctor will do some tests and evaluations. The most common are EEGs (electroencelphalograms used to find electrical activity problems in the brain), including overnight monitored EEGs in an epilepsy unit, and any other imaging tests.
Your doctor may also order other imaging tests such as MRI (magnetic resonance imaging) or PET (positron-emission tomography) scans, if necessary. You will also get a neuropsychological evaluation, which includes a variety of tests done by a neuropsychologist to get a baseline for your cognitive function prior to surgery. If the surgery is for a child under three years old, the doctor will order a developmental evaluation.
Make sure you talk to your doctor about your test results including the reasons why surgery is the best treatment option. You should also schedule an appointment with your primary care doctor and notify your other specialists to let them know you are having neurosurgery.
In the six to eight weeks before your surgery, you should:
- Eat a healthy diet.
- Continue to exercise or remain as active as possible.
- Stay hydrated.
- Keep taking your regular seizure medications as instructed by your doctor.
- Follow your doctor’s instructions for stopping other medications.
- Talk to your family and friends about your upcoming surgery.
- Discuss any concerns or feelings about the surgery with your doctor.
- Work with your care team to determine what kind of support you will need after surgery.
Before the surgery begins, you will meet with your surgical team and neurosurgeon to discuss the procedure and go over any questions or concerns you might have.
