The
number of People with Parkinson’s in New York State, in Erie County,
or any local areas is based on the generally accepted estimate that about 1
million people in the United States have Parkinson’s. As of 2005,
there have not been large, nationwide epidemiological studies that
would give us a more exact number.
-
In
the Buffalo/Niagara Falls Metropolitan Statistical Area (total
population = 1,170,111) there are about 4,100 people with Parkinson’s in
Erie County (total population = 950,265) there are about 3,300.
Mortality
In the United States in 2000 a total of 15,600 deaths were
attributed to Parkinson’s disease, a rate of 5.5 per 100,000 persons in the
total population.
·
Among persons over the age of 65, the death rate was 43.6 per
100,000, a total of 15,300 deaths.
·
Among people 65 years of age and older it is a more common cause
of death than motor vehicle-related injury. 1
·
Patients with PD have a
2.0- to 2.9-fold higher risk of death than those without the disease.2
Diagnosis
Parkinson's disease is the second most common neurodegenerative disease
affecting older people in the United States.
·
Estimated 60,000 new cases are diagnosed in the U.S. each
year.
- 15% of those diagnosed are under 50.
- 5-10% of PWP have symptoms before age of 40.3
Incident Rate
Approximately 1% of the population over age 65 has the disease.
·
The
annual incidence of PD is approximately 20 cases per 100,000 population.
The incidence and prevalence of the disease rise steadily with increasing age.
·
According to the U.S. Bureau of the Census, the prevalence of PD in the United
States is expected to reach 1.3 million to 1.7 million by 2040.2
·
The
percentage of people over age 65 , based on the 2000 Census is higher in Erie
County than for the U.S. as a whole. Therefore the expected incidence of
Parkinson’s and associated economic costs may be even higher in Erie County.4
·
The
percentage of U.S. population 65 years and older (2000 Census) is 12.4.The
percentage in Erie County population 65 years and older (2000 Census)
15.9%.
Economic Costs
PD is one of the
most expensive neurologic diseases treated on an outpatient basis.
The economic
burden on U.S. society of up to $25 billion per year - $25,000 per patient.
The economic costs
of PD include both direct health care costs (for drugs, physician
services, and
hospitalization) and indirect costs ( for lost worker productivity). (2)
With the steady
increase in the population of elderly individuals, the incidence of the disease
and its associated costs are expected to rise. (2)
