The 11th April every year is designated as World Parkinson's Disease Day. The aim of World Parkinson's Disease Day is to raise public awareness of Parkinson's Disease, a medical disorder that begins mildly but that can end up having serious and widespread effects that affect every system in the body.
The 11th April is chosen because it is the birthday of James Parkinson after whom Parkinson's Disease is named. Contrary to common belief, James Parkinson did not discover Parkinson's Disease. The symptoms of Parkinson's Disease have been known and treated since ancient times. Despite all the claimed breakthroughs since then, there are now up to 10 million people with Parkinson's Disease. Tens of millions of people more who are alive right now will eventually have Parkinson's Disease.
However, this is the last century in which Parkinson's Disease will exist. The likely future of Parkinson's Disease is that it will be readily and accurately diagnosed, and effectively treated without side effects, before its characteristic symptoms even become apparent.
