What is Essential Tremor?
Essential tremor is a movement disorder, meaning it affects parts of the brain that control body movement (motor function).
The tremor, or involuntary shaking, is very rapid, generally more than five times a second.
Essential tremor is the most common type of tremor and is mainly found in people over age 65. An Eessential tremor is not dangerous or life-threatening, but it can be annoying and embarrassing for many people.
In some cases, it may be dramatic enough to interfere with:
- Writing
- Eating
- Drinking
- Speaking
Several treatment options can help control symptoms of essential tremor. People whose symptoms have not responded well to medication alone may be candidates for deep brain stimulation at UPMC.
Causes of essential tremor
The cause of essential tremor has not been identified.
Essential tremor might be caused by abnormal electrical fluctuations in the brain. These fluctuations send incorrect signals to the muscles, causing the body to contract.
There are several regions of the brain linked to essential tumor, including the cerebellum, globus pallidus, thalamus, and cortex.
Genetics may be one a factor in the development of essential tremors. It is more common in the elderly and tends to become more pronounced with age. An essential tremor is not dangerous or life-threatening, but it can be annoying and embarrassing for many people.
