Parkinson’s disease is associated with dementia or may lead to dementia. Parkinson’s disease is a progressive disease that affects many middle-aged and older adults. The disease includes symptoms such as tremors, stiffness, slow movement, and impaired balance.
As many as 65% of people with Parkinson’s may develop dementia symptoms as the disease progresses. Sometimes these dementia symptoms are just considered part of the disease, but sometimes a separate diagnosis — for instance, of Alzheimer’s disease — may be made. There is also a great deal of overlap in the symptoms of Parkinson’s disease and Lewy Body dementia, for instance. Physicians use a variety of techniques and tests to make a correct diagnosis.
