Every hour, two people in the UK are told they have Parkinson's disease - a condition in which parts of the brain become progressively damaged over the course of many years.
Parkinson's is caused by a loss of nerve cells in the brain, leading to a reduction in the chemical dopamine, which plays a vital role in regulating our body movements. It's not known exactly what causes this to happen, and there is no cure, although treatments are available to help manage the main symptoms.
There are over 40 symptoms of Parkinson's, ranging from a tremor or stiffness to problems with sleep and mental health, and the signs can be different for everyone according to leading charity Parkinson's UK. It is the fastest-growing neurological condition in the world, the charity says, with around 145,000 people currently living with it across the UK.
