Essential tremor is a disorder of the nervous system that causes involuntary, rhythmic shaking (tremor), especially in the hands. It involves tremor without any other signs or symptoms, and is distinguished from tremor that results from other disorders or known causes, such as tremors seen with Parkinson disease or head trauma. Essential tremor (sometimes called benign essential tremor) is the most common of the more than 20 types of tremor. Essential tremor is a complex disorder. Several genes are believed to help determine an individual's risk of developing this condition. Environmental factors may also be involved. In mild cases, treatment may not be necessary. In cases where symptoms interfere with daily living, medications may help to relieve symptoms.
