What causes Parkinson’s disease
People with Parkinson’s don’t have enough of the chemical dopamine because some of the nerve cells that make it have died, advises Parkinson’s UK.
It adds: “We don’t yet know exactly why people get Parkinson’s, but researchers think it’s a combination of genetic and environmental factors that cause the dopamine-producing nerve cells to die.”
Parkinson’s disease treatment
There’s currently no cure for Parkinson’s disease but there are treatments available to help relieve the symptoms.
