Abstract
ABSTRACT:Parkinson syndrome (PS) is a common disorder in the North American population. The annual incidence rate is 20.5/100,000 population and the mean survival after onset is approximately 12.3 years. The estimated prevalence rate is about 300/100,000 population. The incidence and prevalence rates rise with advancing age. Both the widespread use of levodopa and the improved health care in general have increased the longevity in PS. The survival in PS from the time of the first clinic visit is still significantly shorter when compared with the regional age and sex matched population. The cause of IPD may be related to some environmental factor(s) – most likely a toxin. Genetic factors are not the cause but in some families, may predispose to IPD.
