What is essential tremor?

Essential tremor is one of the most common neurological movement disorders. With essential tremor, the hands, arms, legs and head are usually quiet at rest, but performing a simple task, such as picking up a glass of water, can be difficult. Essential tremor can interfere with many normal activities including signing checks, buttoning clothes, combing hair and cutting food with a knife and fork. In essential tremor, the movement disorder is the only aspect of the disease.
