Essential Tremor

Essential tremor (ET) is a neurological condition that causes shaking of the hands, head and voice, but it can also cause legs and trunk to shake. Some people even have a feeling of internal tremor. ET is often confused with Parkinson’s disease although it’s eight times more common, affecting an estimated 10 million Americans and millions more worldwide. The cause of essential tremor is not fully understood, but clinical research has identified the Vim nucleus of the thalamus as the spot in the brain which can be treated to alleviate the tremor. The thalamus is a structure deep in the brain that coordinates and controls motor activity as well as other functions.
