This is more research out of the Mayo Rochester Epidemiology Project, looking at 461 people in Olmsted County, MN who were diagnosed with a synucleinopathy with parkinsonism between 1991 and 2010. Synucleinopathies included were Parkinson’s Disease (PD), dementia with Lewy bodies (DLB), Parkinson’s Disease Dementia (PDD), and multiple system atrophy-parkinsonism (MSA-p). These were matched with county residents without parkinsonism.
Those with MSA-p died 6 years earlier than others with synucleinopathies, and those with DLB (4 years) or PDD (3.5 years) had a shorter lifespan than normal controls. And having PD took one year off a person’s lifespan.
Here’s a MedPage Today article about the research:

Recently, Clinical Neurology News published these five questions to test your knowledge of outcomes in synucleinopathies — dementia with Lewy bodies, Parkinson’s disease dementia, multiple system atrophy, and Parkinson’s disease:
Most of the questions are about DLB, PDD, and MSA. The questions are based on the JAMA Neurology article.
