How does Parkinson's dementia progress?

My husband was diagnosed with PD 11 years ago, and a year ago was diagnosed as having mild cognitive impairment. This seems to have accelerated somewhat; we are in the loop with the memory clinic and they have suggested that he may have early stages of PD dementia, and have a nurse coming out next week to discuss medication. My mother died eighteen months ago with vascular dementia and I know something about how that progresses, but I can’t find info on how PD dementia behaves or progresses. Anyone…?

Hello, my husband was diagnosed with PD in 2012. About four years ago his concentration and processing of information was becoming less good. We were sent for memory testing and various scans. At the end of all this he was given a diagnosis of Lewy Body dementia. Not uncommon in PD. The way it differs from other kinds of dementia is that my husband has hallucinations and delusions. His memory is not so much affected. I wish you well. C.
