Hi Alice! Like any symptom of dementia, it is all on a spectrum. Essential tremors are more likely to be a symptom in later stages, but they can come early or not at all as well. Tremors are more likely with vascular dementia than with ALZ, but dementia and Parkinson’s effect the same parts of the brain, so the symptoms such as tremors and hallucinations often overlap. My Mom’s physical abilities have declined much faster than her cognitive abilities and although she doesn’t have tremors, her general ability to walk has been effected. We even had an MRI about 5 years after her initial diagnosis because her neurologist wanted to make sure that there wasn’t an additional issue causing the mobility issues. Hope this helps!
My husband has tremors and hallucinations. He is in moderate stage. Tremors have been going on for a long time. Dr says it is essential tremor but could lead to Parkinson’s. He said he can’t really tell between the alz and Parkinsons right now. His balance isn’t good and walking shuffles without picking up his feet. I wonder about it turning into Parkinsons in due time. Will wait and see. Agree with Rebekah they overlap.
