Deep brain stimulation, more commonly known as DBS, is a procedure in which electrical impulses are sent to certain parts of the brain to regulate abnormal impulses. These electrical impulses are carefully administered so there is no permanent damage to healthy brain tissue. Typically, the areas of the brain targeted during treatment are the globus pallidus, subthamatic nucleus and the thalmus.
Some of the conditions deep brain stimulation can treat include:
- Essential tremor
- Parkinson's disease
Currently, there are some studies that suggest deep brain stimulation may be used to treat other conditions like major depression and Tourette syndrome.
Only patients whose symptoms are not responding to medications are considered for deep brain stimulation.
