hi, Essential tremor can be a very disabling condition and can potentially wreck the quality of life of the person. Some medicines like Propranolol, trihexiphenidyl and Primidone are used in an attempt to control it, but they can at best only control the tremors to an extent. The most promising treatment is deep brain stimulation which is an operation in which an electrode is inserted into the brain and connected to a pacemaker. This can potentially cure the patient. Therefore it would be useful to consult with a Functional neurosurgeon who is trained in deep brain stimulation. The alternative method of surgery is called Thalamotomy in which a small area inside the thalamus is burned to produce the same clinical response. However, the tremors can return after some time. Hope this helps.
