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 (brain nuclei) for the treatment of movement disorders, including Parkinson's disease, essential tremor, and dystonia. While its underlying principles and mechanisms are not fully understood, DBS directly changes brain activity in a controlled manner.

What are the benefits of deep brain stimulation?

Pros of Deep Brain Stimulation. Symptom Reduction: DBS often reduces symptoms significantly. These include motor symptoms like stiffness, tremor, slowness and dyskinesia. DBS has also been shown to aid in on/off fluctuations, improve mood and quality of life, and increase overall energy level.

Is deep brain stimulation dangerous?

The risk of serious or permanent complications from DBS therapy is very low. Stroke from bleeding in the brain constitutes a very small risk, and some patients may experience long-term challenges like numbness, slurred speech, and problems with vision.

WIs deep brain stimulation permanent?

The time to consider Deep Brain Stimulation (DBS) surgery is when quality of life is no longer acceptable on optimal medical therapy as administered by a movement disorders neurologist. The major risks are a 1% risk of stroke causing a permanent deficit, due to bleeding in the brain, and a 2-5% chance of infection.

What are the side effects of deep brain stimulation?

Side effects associated with deep brain stimulation may include:
• Seizure
• Infection
• Headache
• Confusion
• Difficulty concentrating
• Stroke
• Hardware complications, such as an eroded lead wire
• Temporary pain and swelling at the implantation site

What is the success rate of DBS surgery?

One analysis has suggested that DBS must achieve a success rate of 83% to be equivalent to bariatric surgery
