Question from Caring.com Community Member, Dragonladynaps
My mom has Parkinson's dementia, but because she is being treated with Alzheimer's meds including Aricept and Namenda, my father truly believes she has Alzheimer's. How can I convince him otherwise?
Expert Answer by Paula Spencer
I'm not sure why you need to convince him -- or can, aside from repeating the facts. Parkinson's Disease Dementia (PDD) and Alzheimer's Disease share many symptoms and, as your mother illustrates, treatments. Both are neurodegenerative brain disorders that progress at similar rates. PDD is common in people with Parkinson's, especially late in the disease.
