We posted earlier this week about the Mayo Rochester research into lifespan for Parkinson’s Disease, Parkinson’s Disease Dementia, Dementia with Lewy Bodies, and Multiple System Atrophy, as compared to those without these disorders.
This is a good Alzforum explanation of the same research:

Here are a few excerpts from the Alzforum article:
* “Prior studies have reported survival rates for various parkinsonian disorders; however, most of these recruited from hospitals rather than the general population, and none compared α-synucleinopathies side by side.”
* David Irwin, University of Pennsylvania wrote to Alzforum: “The comparison of survival…highlights the powerful effect of cognitive impairment and dementia to predict a poor prognosis across the PDD/DLB spectrum. Further, there is limited data on the natural history of MSA, and this paper provides new insight into the relatively rapid progression of this disease.”
* “[Mayo Rochester researcher] Savica said his group has submitted one autopsy study for publication, and will expand on pathology in an upcoming project.”
