TREMORS AND PARKINSONS? What types of tremor do people with PD have?
Tremor is the repetitive, involuntary shaking of a body part, most commonly the hands or head. It can be a disorder in its own right, or it can be a sign of another health problem.
There are several different types of tremor, all of which fall into one of three main categories:
Resting tremors — Resting tremors happen while you are sitting or lying down and relaxed. People who have a resting tremor can usually stop the tremor by deliberately moving the affected body part.
Postural tremors — Postural tremors happen when you try to hold a body part still, against the force of gravity. If you have a postural tremor, your arms might shake if you hold them out in front of you.
Action tremors — Action tremors happen when you move deliberately.
Learning whether you have a resting, postural, or action tremor is the first step in discovering the cause of your tremor and its potential treatment. The different categories of tremor usually have very different causes.
MOST COMMON CAUSES OF RESTING TREMOR
Parkinson disease — The most common cause of resting tremor is Parkinson disease. If that is the cause of your tremor, your healthcare provider will probably focus on treating the Parkinson disease in the hopes that doing so will also alleviate the tremor.
In a few instances, people with Parkinson disease who have a resting tremor also have an action tremor.
Other causes — Other possible causes of resting tremor include:
●Rubral tremor, caused by conditions that damage part of the brainstem
●Wilson disease, a rare inherited disease that causes copper to build up in the body
