Mercy's Deep Brain Stimulation Program

As many as one million Americans live with a movement disorder, with another 60,000 patients diagnosed each year. For those living with the disease, relief can come in many forms, including medication and exercise therapy. For many, medical management of their symptoms isn’t enough, and a surgical intervention, known as deep brain stimulation, could be the treatment they need.

What is deep brain stimulation?

This Food and Drug Administration (FDA) approved procedure is made up of two separate surgical stages. In the first, the patient has a very thin electrode, or lead, implanted into a specific region of the brain. This is done using incredibly sophisticated equipment to allow for precise placement. At the end of the lead are four contacts, which provide adjustable electrical pulses to areas of the brain. Generally, patients will be kept awake for portions of this procedure in order to provide important information and feedback regarding lead placement.

In a separate procedure, the patient is put to sleep to have the lead connected to a wire called an extension and attached to a neurostimulator generator which has been implanted under the patient’s collar bone or in the abdominal area. A neurostimulator is essentially a brain pacemaker. Its job is to control the release of electrical signals to the region of the brain where the lead is implanted and allows for adjustment in the electrical signals long after surgery.

Mercy's deep brain stimulation program focuses on each half, or hemisphere, of the brain at a time in order to monitor patients more closely. Patients will undergo the procedures described above twice; once for each half of their brain.

What to expect at Mercy Neurosurgery

Patients with the following disorders will undergo a series of consultations to determine if deep brain stimulation is an option for them:

  • Parkinson’s disease
  • Essential Tremor
  • Dystonia
  • Movement disorders
  • Affective disorders, such as treatment resistant obsessive-compulsive disorder

Patients will work closely with Dr. Randall Hamilton, neurologist, and Dr. Jim Androkopolous, neuropsychologist, out of Mercy's Ruan Neuroscience Center to monitor their progress and help adjust the electrical pulses from the lead.
