Parkinsons Disease Statistics
|
In the United States, at least 500,000 people are believed to suffer from Parkinson's disease, and about 50,000 new cases are reported annually. These figures are expected to increase as the average age of the population increases. The disorder appears to be slightly more common in men than women.
The average age of onset is about 60. Both prevalence and incidence increase with advancing age; the rates are very low in people under 40 and rise among people in their 70s and 80s. Parkinson's disease is found all over the world. The rates vary from country to country, but it is not clear whether this reflects true ethnic and/or geographic differences or discrepancies in data collection.
