None of these people had grueling schedules, drug or alcohol problems or outlier lifestyles and all had office jobs. There was some speculation about an office for two of them that had once been a chem lab.
For anyone who hasn't seen Dark Waters yet, I would recommend watching it, or at least reading up on the Chemical Industry's shady business practices. Let's just say we no longer use non-stick pans in our household. (This is not to say it has a connection specifically to Parkinson's).
Yet who one Earth has never, even for a few seconds, had something happen while cooking. A distraction. A mistake with the heat. An accident requiring attention, a small child taking attention away.
One mistake, one moment of error, and now the teflon is toxic.
Meanwhile, there are endless warning labels all over packages for absolutely absurd things. Such a bizarre world.
What gets me, is that there are all sorts of replacement non-stick coatings. All brand new, all "Oh yes that's perfectly safe!", people happily buying those.
Iron or stainless steel for me, thank you.
Companies don't want to list negative stuff on the label because people look, then don't buy.
I found out the I had a lot of trouble with Sodium Lauryl Sulfate - my sheets would irritate me after I washed them, and it was a relief to find a detergent without it. (also goes for shampoo, toothpaste and lots more)
But the lengths companies go to when hiding it on the ingredients list. They name it something else.
See "other names" on this page:
https://en.wikipedia.org/wiki/Sodium_dodecyl_sulfate
I think hiding the type of non-stick coating on a frying pan or a toaster has a lot in common with obscuring SLS.
I'm rural, and so have my own well. One side effect is that depending on rainfall, and other factors, the hardness of my water changes.
Quite literally, I sometimes need to use 3x the detergent. Further, it is not entirely clear when to use 3x the detergent. I don't have time to do one of these every wash (other kits aren't suitable for my water):

Anyhey, so I always just add vinegar after the wash, and do a second rinse. As this fixed most of my issues, I used to get rashes, and now I do not, it may be that vinegar is additionally effective at removing SLS.
Just a FYI, although I have zero idea if valid. Just that "irritation goes away" for me.
Edit for clarity:
I tend to add a full cup of vinegar, and sometimes more. The vinegar tends to rinse out very well.
I read this: https://en.wikipedia.org/wiki/Hard_water
"With hard water, soap solutions form a white precipitate (soap scum) instead of producing lather, because the 2+ ions destroy the surfactant properties of the soap by forming a solid precipitate (the soap scum)."
I wonder if the vinegar helps clear this out.
SLS is a surfactant. I don't know how it all works together.
As you cannot tell the perfect amount of soap to add, unless you know the precise hardness at that moment, water like mine which is variable means a simple thing.
I am simply forced to add 3x the soap of the 'low range' of my water hardness, thus ensuring the clothes are effected by the soap.
Yet with amounts like that, all the soap has a difficult time washing out. Vinegar really helps, as an acid, to nullify the soap and wash it out.
So my target is not SLS in specific, just 'soap is a base, so acid should help get rid of it', which seems to work.
Some organisms cannot handle acid as well, so it may help in other respects.
Doctors flat out don’t care how it happened, and want nothing to do with paperwork.
So getting legal or even basic disability was impossible.
So yea environmental factors are a big deal.
