That chemical is trichloroethylene. Even Science does clickbait now.

Not sure I'd call it clickbait, and they do mention it right away. It'd be like putting a mathematical expression in the headline of an article about neural networks.

It was heavily contaminated water that they all consumed, of the 279 veterans there were 0.33% cases vs the statistically expected 0.21%. Which means they found 9 people with Parkinson, instead of the expected 6.

[edit] ignore the comment, read it wrong, its 279 cases

When you drink your coffee without caffeine in your 30 for escaping a harm from caffeine, but end up with Parkinson in your 60+.

Fortunately it's a big increase in relative risk and not absolute risk:

By 2021, 279 of the Camp Lejeune veterans, or 0.33%, had developed Parkinson’s versus 151 of those at Camp Pendleton, or 0.21%. After adjusting for differences in age, sex, race, and ethnicity, the scientists found veterans from Camp Lejeune had a 70% higher rate of Parkinson’s disease than the Camp Pendleton group.

I guess it can be encouraging news for some people. My mom died with Parkinson's and I've almost certainly had less exposure to TCE than she did. I'm aware that there isn't really a known genetic link, it's just nice to occasionally see evidence that it can be exposure related. The increase in prevalence mentioned in the article isn't good, but that can be due to better techniques for diagnosing it.

The 279 is identified cases of Parkinson's, the study included tens of thousands of people.

Why didn't they adjust for socioeconomic status? Wealthier people tend to be able to afford better medical care, live in healthier environments, eat healthier foods, etc.

These could all be confounding factors, and a study like this should take them in to account.
