is there a relationship between parkinson's and dementia?
Parkinson's is a disease which affects the brain, causing problems with movement. The muscles become stiff and sometimes shake, and the person moves more slowly than normal. Parkinson's and dementia are linked because, in some people with Parkinson's disease, dementia may occur as the illness progresses. Dementia is a disorder in which brain function deteriorates, leading to difficulties with remembering, planning and organizing, recognizing people and things, and communicating with others.
