WHAT TO EXPECT DEEP BRAIN STIMULATION FOR ESSENTIAL TREMOR

EVALUATION — DETERMINING IF YOU ARE A CANDIDATE

Your neurologist — typically a movement disorder specialist  — will evaluate you to see if DBS is a good option for you. The evaluation usually includes:

• Medical history
• Neurological exam of your movements, both on and off medications
• MRI of the brain to check whether there are any issues that would pose a risk during the surgery
• Lab tests, such as a blood test to make sure your blood clots properly
• Neuropsychological tests

The doctor will share the results with you, and together you will decide whether or not to go forward with the therapy.

PLANNING — PREPARING FOR SURGERY

Your doctor will create images and maps of your brain to help guide the placement of leads during the surgery. You will have an MRI or CT scan to capture images of your brain.

SURGERY — PLACING THE SYSTEM

There are two parts to the DBS surgery: implanting a thin wire (lead) in the brain and placing the pacemaker-like device, called the neurostimulator, under the skin of the chest. The two parts may be done on the same day, or two different days. 

PROGRAMMING — GETTING THE INITIAL SETTINGS RIGHT

A few weeks later, your doctor will turn on the neurostimulator and adjust the stimulation to best control your symptoms while minimizing side effects.

• Most people don't feel the stimulation at all when it’s first turned on, but some feel a brief tingling.
• It will take a few programming sessions to find the stimulation levels that work best for you — don't get discouraged.
• You'll have follow-up visits to check your results and adjust as needed. These appointments are key to getting the results you want over time.

CONTINUOUS THERAPY — RETURNING TO REGULAR ACTIVITIES

Then it's time to get back to your life!

• Return to your usual activities, always following your doctor's guidance on what's okay and what to avoid.
• DBS delivers therapy 24 hours a day, so it's working to control your symptoms when you wake up first thing in the morning.
• DBS doesn’t require any maintenance from you (except for recharging if you have a rechargeable system).

CHECKUPS — ONGOING CARE

It's extremely important to attend all of your checkups with the doctor who manages your DBS therapy. Your doctor will:

• Make sure that your DBS system is working properly.
• Adjust your stimulation to best control your symptoms.
• Check the battery of your neurostimulator to see when you may need a device replacement.
