Introduction

If you're an older adult, you may have dismissed trembling hands or a shaking head as a normal part of the aging process. But it's more likely your shakiness is a sign of a movement disorder called essential tremor.

Although essential tremor can affect almost any part of your body, trembling occurs most often in your hands, especially when you try to do simple tasks such as drinking a glass of water, tying your shoelaces, writing or shaving. Sometimes, you may also have trembling of your head, voice or arms.

Essential tremor is the most common of the many movement disorders. It's far more common than Parkinson's disease, with which it may sometimes be confused. Unlike Parkinson's disease, however, essential tremor doesn't lead to serious complications. In fact, the word "essential" in essential tremor means the disorder isn't linked to other diseases.

For some people, essential tremor may be distressing but not debilitating. Others may find that their tremors make it difficult to work, perform everyday tasks that require fine-motor skills or do the things they enjoy. Severe tremors can lead to social withdrawal and isolation. Fortunately, a variety of treatments exist that may help bring your tremors under control.
