Overview

The incidence of essential tremor increases with age.
The incidence of Parkinson's disease is in the range of 8 to 18 per 100,000 people yearly^[1].

The prevalence of essential tremor is approximately 0.4% to 5.6%^[2].
Seven million people worldwide and one million people in the United States are suffering from Parkinson's disease.
The prevalence of [disease/malignancy] is estimated to be [number] cases annually.

In [year], the incidence of [disease name] is approximately [number range] per 100,000 individuals with a case-fatality rate/mortality rate of [number range]%.
The case-fatality rate/mortality rate of [disease name] is approximately [number range].

Essential tremor has bimodal incidence according to age, early in life especially second decade, and then in older age groups. The incidence increases with age.
Incidence of Parkinson's disease increases with age, 1% of the population over 60 are affected and 4% of the population over 80.
Mean age-of-onset of Parkinson's disease is 60years^[3].

Prevalence of Parkinson's disease is higher in Caucasians as compared to black or East and oriental populations^[4].

[Disease name] affects men and women equally.
Males are more commonly affected by Parkinson's disease than [female]. The [male] to [female] ratio is approximately 3:2^[5].

Parkinson's disease affects more Caucasians as compared to black or East and Southeast Asian populations^[4].
