Is there a correlation between Parkinson's disease and Alzheimers/dementia? Google doesn't directly have the answer, but it seems that the answer is yes:
From Twitter
Under 2% of elderly have Parkinson's: https://pubmed.ncbi.nlm.nih.gov/8848182/
WHO: 5–8% of people of people aged 60 or older have dementia: https://www.medicalnewstoday.com/articles/elderly-dementia-symptoms
But "at least 75% of PD patients who survive for more than 10 years will develop dementia": https://pubmed.ncbi.nlm.nih.gov/19733364/

Anyway, I find it interesting that studies show coffee decreasing amounts of dementia/PD risk factors...

https://pubmed.ncbi.nlm.nih.gov/36361750/
...but that when I Googled ways to lower Alzheimer's risks, I looked at 4 sites and none of them mentioned caffeine or coffee.

Also "The risk of dementia in PD is about 1.7- to 5.9-times higher compared to controls" https://www.frontiersin.org/articles/10.3389/fneur.2021.748096/full
However, no one seems to be talking about whether there is an increased risk of Parkinson's after a Dementia diagnosis. Does PD tend to happen before AD somehow?
