Do they still use a gamma knife to treat essential tremors?
There have been published descriptions of using stereotactic radiosurgery (of which Gamma Knife is one subtype) to create a lesion in the thalamus for essential tremor, although I have not found reason to offer this to patients myself. One major drawback of the therapy is that it is challeging to be sure about the size of the lesion being created, and that once created, the lesion cannot be adjusted (i.e. in case of side effects).
