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.
Watch our short video to find out more about Parkinson's.
3 things we know about Parkinson's
Parkinson's develops when cells in the brain stop working properly and are lost over time. These brain cells produce a chemical called dopamine.
Symptoms start to appear when the brain can’t make enough dopamine to control movement properly.
There are 3 main symptoms - tremor (shaking), slowness of movement and rigidity (muscle stiffness) - but there are many other symptoms too.
When will there be a cure?
Thanks to your part in a 50 year research story, we understand more about the condition than ever before.
Funding the right research into the most promising treatments, we get closer to a cure every day. We can do. But we can't do it without you.
