Parkinson’s Dementia

Dementia in Parkinson’s Disease

Around 30% of all people living with Parkinson’s disease of any age will develop dementia, although some people will experience some degree of difficulty with cognitive functions such as memory and thinking without ever developing a dementia. There are two primary forms of dementia that occur in people living with Parkinson’s disease. These are;

  • Dementia with Lewy Bodies (which you can find more information about here) (hyperlink to types of dementia- dementia with lewy bodies)
  • Parkinson’s dementia

Parkinson’s dementia occurs when someone has already had motor symptoms of Parkinson’s disease for some time. Experiencing signs of dementia can be difficult to come to terms with when a person already has a diagnosis of Parkinson’s disease. For this reason it is particularly important to talk with a trusted healthcare professional about your concerns if you feel that you are experiencing difficulties with memory and thinking skills.
