Description
Cognitive problems are common in Parkinson’s Disease but may reflect co-existing pathologies that are also increasingly prevalent in older age. Furthermore, given the imprecision of ante-mortem diagnosis, it is important in any discussion about the dementia of Parkinson’s to also consider the other neuropsychiatric problems that may occur in Parkinson’s; other dementias associated with Parkinsonism, such as dementia with Lewy bodies, vascular dementia, and Alzheimer’s-type dementia.
