Parkinson’s disease affects around seven to 10 million people worldwide. The distribution of the disease is relatively homogeneous. Parkinson’s disease normally begins when patients are between the ages of 50 and 70, but it can occur at any age. It is the second most common cause of physical disability in the elderly, followed by strokes. It is not known why, but Parkinson’s disease affects slightly more men than women.
