Tremor: A Common Symptom of Parkinson's Disease

What is Tremor?

Tremor is an involuntary, rhythmic shaking or slight movement that typically occurs in a limb, such as the hand or fingers. It is often the first motor symptom of Parkinson's disease and can affect a wide variety of body systems.

How does Tremor Affect Parkinson's Disease?

Parkinsonian tremor affects 80% of people with Parkinson's disease. It usually occurs at rest, but can also be triggered by stress, anxiety, or certain medications. The typical Parkinsonian tremor is characterized by a back-and-forth movement, with a frequency of 4-6 times per second.
