Parkinson's Disease
About Parkinson's Disease
Parkinson's disease is a progressive neuro-degenerative condition in which the dopamine producing nerve cells of the brain are lost. Once 60-80% of these cells have been lost the co-ordination of body movements by the brain will be affected causing difficulties with, for example, the person's ability to walk, talk and write.
The symptoms of Parkinson's disease usually appear after the age of 50 although in about 5% of cases the person will be under 40. Males are slightly more likely to be affected than females.
