Deep brain stimulation

Deep brain stimulation - or thalamic stimulation - is a type of surgery that is sometimes used to treat severe tremor if other treatment options haven't worked. It involves placing electrodes in a part of the brain called the thalamus. They deliver a small electric current which can help calm the tremor. The technique was originally developed to treat tremor in people with Parkinson's and is less successful at treating MS tremor. However, it can help some people.
