What is Tremor?

Tremor is the involuntary or unintentional rhythmic movement of one or more parts of the body and it may involve the hands, arms, legs, face, head, trunk, or vocal cords. It may be caused by a number of factors such as neurological disorders due to various causes with Parkinson’s disease being one of them as well as certain drugs, alcohol abuse or withdrawal, mercury poisoning, hyperthyroidism, or liver failure. Certain types of tremors may be inherited and are seen to run in families, but for which no known cause can be found, and these are called essential tremors.

One of the most significant symptoms noted in the early stage of Parkinson’s disease is the characteristic tremor, especially of the hands, often referred to as the Parkinson’s tremor. This is among the earliest symptoms of Parkinson’s disease and often the main reason why new sufferers seek medical treatment even if they had previously ignored other initial symptoms. A Parkinson’s tremor may vary from mild to severe and is initially noted in the hands, particularly the jaw, although other muscles may be affected, like the jaw muscles.
