Does Parkinson's Disease only affect a specific age group? If so, what age?
Parkinson's Disease is more commonly found in the elderly population; however, in 1875, Henri Huchard had a patient that had all of the symptoms of Parkinson's Disease. This patient was only three years old.
It is estimated that approximately 1.5 million Americans have Parkinson's disease. Men are slightly more likely to develop the disease than women, and approximately 60,000 new cases are diagnosed each year. Because the majority of people who get Parkinson's disease are over the age of 60, it has been (and continues to be) thought of as an "older person's" disease. Because of this, the disease is often overlooked in younger people, leading many to go undiagnosed or misdiagnosed for extended periods of time. In fact, about 10%-20% of those diagnosed with Parkinson's disease are under age 50, and about half of those are diagnosed before age 40.
