Parkinson’s disease (Parkinson’s) is a progressive neurological disorder, and is classified as a Movement Disorder, as it primarily affects movement. It is variable in its progression, i.e. some people progress more slowly than others, and the symptoms can be effectively controlled with medication for many years. Parkinson’s disease is caused by a loss of a chemical called dopamine. We all lose some of this chemical as we get older, however, it is only when we have lost about 80% of our dopamine we start to have symptoms. So people with Parkinson’s have lost this chemical at a faster rate than others. For more information read Parkinson’s Ireland leaflet: G1.1 What is Parkinson’s?
