When you run out of HN, do you hit up ChatGPT?

I ask ChatGPT to write me a comment thread in the style of Hacker News.

Certain pesticides are confirmed causes of Parkinsons. Don't remember which now, but could look it up.

No, none are "confirmed causes". There are mild associations between the use of certain pesticides and Parkinson's, but much lower than the overall genetic risk factors, and there's always the possibility of confounding factors in the studies.

Pick up a nicotine addiction. Seriously, it has long been understood that people who smoke have dramatically lower levels of parkinsons. It comes from the neuroprotective properties of nicotine. You don't have to become a smoker, you could theoretically use any of the other forms (vape, gum, patch)

https://www.apdaparkinson.org/article/smoking-and-parkinsons... Smoking and Nicotine addiction are still bad.

Nicotine is wonderful. 2mg and 4mg lozenges are readily available, you don't have to take up smoking to get it. It's excellent for many, many things: cognition, focus, appetite control, positive habit formation, etc.

Addiction is literally its only downside.

Interesting that big flu outbreaks cause a long term spike in Parkinson's - how much more will be traced back to the impact of viruses? Saw that come up as a worry around Covid, seems the loss of smell/taste is a commonality with Parkison. We will not know for a decade or two though, but these biomarkers might help accelerate measuring the impact.

I am currently struggling with the idea of going back to vaping, having quit 3 years ago following covid, because nicotine has consistently shown to be a strong drug for fending off parkinsons.

Would nicotine patches help?

Maybe. The correlation is weak. If you're looking for a stronger correlation, try obesity.

People who are very overweight or obese in middle age (35-55) are significantly more likely to develop Parkinson's after 60, even if they lose the weight prior to diagnosis. Now this could be a pure lifestyle-correlation, but my spidey sense suggests it's causative, knowing how causative obesity is for SO MANY other degenerative and chronic diseases.

The best advice you can give anyone, at any time, for the prevention of nearly every poor health outcome we have a name for is and always will be: don't get fat; if you're fat, stop being fat.

I could do that, but I smoked cigarettes for 7 years and then vaped for 9 years. So I don't know if I could jump back into nicotine but hold off on the smoking/vaping aspect of it.

There are actually a number of different pesticides that are linked to parkinson's. It's especially strong for farmers who get a much larger dose than the people consuming the food - simply type "parkinson's farmer pesticide" into google scholar. One example is Paraquat, which is already banned in numerous countries but not US [1]. Aside from this Parkinson's link being established in farmers who use Paraquat, it's found it rats too.

Another is rotenone [2].

For those living in the bay area, you should know that the groundwater in many areas is contaminated with TCE due to computer manufacturing industry which used it as a solvent. Dry cleaners are another common culprit of contamination to the groundwater. These groundwater plumes can extend for quite a large distance from the original site of contamination and seep into the first story of residences and buildings through vapor intrusion. The TCE solvent is directly linked to Parkinsons [1].

Take a look at where you live on the California waterboard website [2] and look for nearby groundwater contamination sites. TCE / PCE contamination sites anywhere near your residence or workplace would put you at risk of getting Parkinsons. I know someone who got it and indeed they lived near a dry-cleaner that was leaching TCE into the groundwater decades ago. The solvent entires your residence through vapor intrusion, especially on the first floor or basement.

Had to start researching this when a family member was recently diagnosed. Parkinson's has many forms and many causes. There's a big divide between Parkinson's _disease_ (idiopathic Parkinson's) and Parkinsonism from a variety of sources - stroke, drug-induced, and so on. There are also other conditions, like progressive supranuclear palsy, that are considered either to masquerade as Parkinsonism or to constitute ano…

In The Netherlands we have A LOT of farmers with parkinsons. Most, if not all cases seem to be related to Roundup/Glyphosate.

The first study has 3 patients. The second study is a little better, but not by much. Both have the same first author. If this were legitimate, some academic medical center in the US would have picked it up. Parkinson’s is a huge target, and this kind of thing makes a career. This is likely on the same level as horse dewormer for COVID.

That something sounds strange doesn't particularly lead me to question the likelihood of efficacy.

The evidence on something's efficacy leads me to question something's efficacy.
