Tremor - Topic Overview

Tremor is an involuntary shaking movement that is repeated over and over. Although it may affect any part of the body, tremor most often affects the hands and head. Your voice may also shake. Sometimes the feet or torso may also shake.

Essential tremor, which sometimes runs in families, is one of the most common types of tremor. It is shaking that is most noticeable when you are doing something like lifting a cup or pointing at an object. The shaking does not occur when you are not moving. Medicine can help reduce the shaking. Brain surgery can be helpful in some cases.

Understanding Parkinson's Disease -- Diagnosis and Treatment

Usually, the outward symptoms of Parkinson's are distinctive enough for a doctor to make a diagnosis in the office.  There is no blood test or brain scan that confirms the diagnosis. But if you don't respond to the drugs used to treat Parkinson's disease, it’s possible you may have another type of movement disorder that causes the same type of symptoms.  Doing additional tests can help your doctor determine if some other problem is causing your parkinsonian symptoms.

Tremors can also be caused by conditions or medicines that affect the nervous system, including Parkinson's disease, liver failure, alcoholism, mercury or arsenic poisoning, lithium, and certain antidepressants. Side effects from other medicines can also cause tremors.

If you notice a tremor, observe it carefully and note what seems to make it better or worse before calling your doctor. There are some differences between essential tremor and tremor caused by Parkinson's disease. If a cause is discovered, the disease will be treated rather than the tremor.
