A neurologist with special training in Parkinson's disease is most often the best kind of doctor to make a decision about deep brain stimulation. If you might benefit from the operation, your neurologist can refer you to a brain surgeon with experience doing the surgery.
Deep brain stimulation may be considered as an addition to levodopa therapy, not a replacement for it. It does not cure Parkinson's disease and does not eliminate the need for medicine. The surgery can help maintain and extend the benefits of levodopa therapy. But it should not be considered for people with Parkinson's disease who also respond poorly to levodopa therapy.
Because of an increased risk of falling in people who have DBS, it's a good idea to understand the ways you can prevent falls after the surgery.
One of the possible advantages of deep brain stimulation over "lesional" surgery for Parkinson's disease (such as pallidotomy) is that it can be changed or reversed. The effects of lesional surgery, which involves creating a lesion or intentionally destroying a small portion of the brain, are permanent, but the electrodes used in deep brain stimulation can be adjusted, turned off or removed if they cause problems.
Deep brain stimulation for tremor caused by multiple sclerosis (MS) is still experimental, expensive and not widely available.
