In most patients with essential tremor, handwriting is impossible
or at best illegible. Drinking from a cup, cutting with a knife,
or bringing a forkful of food up to one’s mouth is impossible.
Some medications may be helpful in controlling essential tremor
early on but as the tremor worsens medications are not usually
effective.
Conventional open stereotactic neurosurgery or non-invasive Gamma
Knife Radiosurgery can be performed to relieve symptoms of essential
tremor. While conventional open neurosurgery requires the use
of a needle or an external guiding device, the Gamma Knife uses
201 narrow beams of gamma radiation to treat a small, critically
located target in the brain non-invasively.
