Parkinson's is a progressive neurological condition. This means that it causes problems in the brain and gets worse over time. Most people who develop Parkinson’s are over 50 but younger people can develop it too. Parkinson’s develops when cells in the brain stop working properly and are lost over time.
There are three main symptoms - tremor (shaking), slowness of movement and rigidity (muscle stiffness) - but there are many other symptoms too.
