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.
Epidemiology and Demographics
Incidence
- The incidence of essential tremor increases with age.
- Incidence of essential tremor is 23.7 per 100,000 annually. [1]
- The incidence of Parkinson's disease is in the range of 8 to 18 per 100,000 people yearly. [2]
Prevalence
- The prevalence of essential tremor is approximately 0.4% to 5.6%. [3]
- Seven million people worldwide and one million people in the United States are suffering from Parkinson's disease.
- Exact prevalence of psychogenic tremor had not been determined, but it is thought to be high. [4]
Age
- 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. [5]
- Orthostatic tremor usually targets sixty plus population.
Race
- Prevalence of Parkinson's disease is higher in Caucasians as compared to black or oriental population. [6]
Gender
- Males are more commonly affected by Parkinson's disease than female. The male to female ratio is approximately 3:2. [7]
- Females are more commonly affected by orthostatic tremor than males.
Region
- Parkinson's disease affects more Caucasians as compared to black or East and Southeast Asian population. [6]
- Parkinson's disease is more common in rural population.
