Overview

The incidence and prevalence of tremor as a symptom is not determined. The incidence of essential tremor increases with age and has bimodal incidence according to age. Prevalence of essential tremor is approximately 0.4% to 5.6%. The incidence of Parkinson's disease is in the range of 8 to 18 per 100,000 people yearly. Seven million people worldwide, and one million people in the United States, are suffering from Parkinson's disease. Parkinson's disease is higher in Caucasians as compared to black or oriental populations. Parkinson's disease is more common in rural populations.
