What is Parkinson's?
Parkinson's is a progressive neurological condition. This means that it causes problems in the brain and gets worse over time.
The number of people diagnosed with Parkinson's in the UK is about 145,000. That's around 1 adult in every 350.
People with Parkinson's don't have enough of the chemical dopamine because some of the nerve cells that make it have died.
Our researchers are working hard to develop new and better treatments - and one day a cure.
