Tremor

What is Tremor?

Tremor is an involuntary shaking of body parts. Sometimes the shaking is associated with a movement (such as writing or holding something in the hands), and in some cases the shaking happens while staying still. Tremor can affect the hands, arms, legs, and even the voice. There are many causes. Two of the most common causes are Parkinson's disease and essential tremor, which is often familial.

Who gets Tremor?

Anyone can get tremor, but it is more common in people over the age of 60. If a parent has tremor, chances are increased for their child to also have tremor.

How is Tremor diagnosed?

After taking the patient's history, a physician may perform physical tests, a blood test, or a magnetic resonance imaging (MRI) scan. Electrodiagnostic studies can sometimes be useful in helping to determine the cause of a tremor.

How is Tremor treated?

The treatment depends on the cause. Medication can sometimes help tremor, as can some lifestyle changes. Botulinum toxin injections are used occasionally.
