What is DBS used to treat?
Deep brain stimulation (DBS) is a surgical procedure used to treat several disabling neurological symptoms—most commonly the debilitating motor symptoms of Parkinson's disease (PD), such as tremor, rigidity, stiffness, slowed movement, and walking problems.
How is DBS performed?
DBS is a surgical procedure that delivers high-frequency electrical stimulation to precise areas of the brain. This is done by implanting a thin wire with electrodes at the tip. The electrodes are precisely placed into a brain site that carries the abnormal signals producing the symptoms.
How long does DBS treatment last?
Associated with several positive outcomes in patients with PD, including decreasing risk of disease progression, researchers say that STN-DBS has been shown to maintain efficacy in patients up to 11 years after surgery. However, conflicting reports have indicated DBS may lose efficacy over time.
How successful is DBS surgery?
“It's not investigational or experimental.” Around the world, more than 150,000 patients have had DBS for Parkinson's or tremor with a success rate of 95%.
How painful is DBS surgery?
Expect some side effects, but the procedure is not very painful. In the weeks and months following a DBS procedure, patients may experience some side effects, depending on medications and the initial programming. The side effects can include abnormal sensations, numbness, tingling, and involuntary muscle contractions.

Doctors may use DBS for movement disorders or neuropsychiatric conditions when medications have ...
What is stereotactic DBS surgery?
Stereotactic DBS surgery requires the patient to be off their medication. During the procedure, a frame stabilizes the head and provides coordinates to help the surgeons guide the lead to the correct location in the brain. The patient gets local anesthesia (numbing medicine) to keep them comfortable throughout each step along with a mild sedative to help them relax.
How long after a lead implant can a neurostimulator be used?
In some cases the surgeon will insert both the lead and the neurostimulator; in other instances the two surgeries may be performed separately, with the neurostimulator implanted days or weeks after the lead is placed.
What is the importance of pulse generators in DBS?
Proper patient selection, precise placement of the electrodes and adjustment of the pulse generator are essential for successful DBS surgery. DBS does not fully resolve the symptoms of PD or other conditions, but it can decrease a patient’s need for medications and improve quality of life.
How does electrical stimulation work?
Electrical stimulation administered through the lead for a short period helps the doctors see if symptoms improve or if side effects (such as muscle contractions or visual phenomena) appear. An extension wire is attached to the lead and placed under the scalp, connecting the lead to the neurostimulator.

The DBS System Consists of Three Components. The lead (also called an electrode) is a thin, insulated wire inserted through a small opening in the skull and implanted in the brain. The tip of the electrode is positioned within the targeted brain area. The extension is an insulated wire passed under the skin of the head, neck and shoulder, ...
How long does DBS last?
It is most effective for people who experience disabling tremors, wearing-off spells and medication-induced dyskinesias, with studies showing benefits lasting at least five years.
What happens if you reduce your dose of anesthesia?
The reduction in dose of medication leads to decreased risk of side effects such as dyskinesia (involuntary movements of the arms, legs and head). There is a one to three percent chance of infection, stroke, cranial bleeding or other complications associated with anesthesia, per side that is done.

What is deep brain stimulation?
DBS uses electrical impulses to change or block the brain’s electrical signals that are causing your symptoms. These impulses are delivered by electrodes surgically implanted in specific areas of your brain.
Placing and programming your device
Our team will first do some tests to determine if DBS is likely to be safe and helpful. They’ll talk about the potential risks and benefits and answer any questions you might have. If you decide to proceed, they’ll do more tests to determine the area of your brain to target.

The types of pulses used (called the waveform and frequency) and the location of the lead (and so electrodes) is determined for each patient based on the on a symptomatic basis, with the help of anatomical brain scans collected by a MRI or CT, and following the advice of the medical team. There are different theories of how DBS works, but what is for certain is that the electrical pulses stimulate neurons around the electrodes, which changes brain function in a way that reduces symptoms.
What is a DBS device?

Deep brain stimulation. Deep brain stimulation ( DBS) is a neurosurgical procedure involving the placement of a medical device called a neurostimulator (sometimes referred to as a "brain pacemaker"), which sends electrical impulses, through implanted electrodes, to specific targets in the brain ...
What is the DBS system?
The DBS system consists of three components: the implanted pulse generator (IPG), the lead, and an extension. The IPG is a battery -powered neurostimulator encased in a titanium housing, which sends electrical pulses to the brain that interfere with neural activity at the target site. The lead is a coiled wire insulated in polyurethane with four platinum-iridium electrodes and is placed in one or two different nuclei of the brain. The lead is connected to the IPG by an extension, an insulated wire that runs below the skin, from the head, down the side of the neck, behind the ear, to the IPG, which is placed subcutaneously below the clavicle, or in some cases, the abdomen. The IPG can be calibrated by a neurologist, nurse, or trained technician to optimize symptom suppression and control side effects.
What areas of the brain are treated with neural stimulators?
Four areas of the brain have been treated with neural stimulators in PD. These are the globus pallidus internus, thalamus, subthalamic nucleus and the pedunculopontine nucleus. However, most DBS surgeries in routine practice target either the globus pallidus internus, or the Subthalamic nucleus.

Is DBS a good treatment for Tourette syndrome?
DBS has been used experimentally in treating adults with severe Tourette syndrome that does not respond to conventional treatment. Despite widely publicized early successes, DBS remains a highly experimental procedure for the treatment of Tourette's, and more study is needed to determine whether long-term benefits outweigh the risks. The procedure is well tolerated, but complications include "short battery life, abrupt symptom worsening upon cessation of stimulation, hypomanic or manic conversion, and the significant time and effort involved in optimizing stimulation parameters". As of 2006, five people with TS had been reported on; all experienced reduction in tics and the disappearance of obsessive-compulsive behaviors.
