Parkinson's disease is quite common. In the UK about 1 in 500 people have it.
Around 120,000 people in the UK have Parkinson's.
Every year, about 10,000 people in the UK are told they have the disease.
Your chances of getting Parkinson's increase as you get older. Since people are now living longer than ever today, more people are getting the disease.
Many people with Parkinson's disease, especially those who are very old, are never diagnosed with the disease. This may be because people confuse the symptoms of Parkinson's with the normal signs of ageing. So they don't go to the doctor to have these symptoms checked.
