What are the results of thalamic deep brain stimulation for tremor?
Deep brain stimulation can dramatically reduce hand tremor in those people with essential tremor. In many cases, the tremor can be eliminated. Most people acquire at least 75% relief. This may last for many years, with occasional programming adjustments needed to maintain the effects. Tremor due to other causes (multiple sclerosis, brain trauma) is more difficult to control, requires more frequent programming adjustments, and may only provide 50% tremor relief. However, this may be a significant aid to someone who is disabled by tremor.
