> Parkinson’s disease results from the progressive loss of dopamine-producing neurons in the substantia nigra. Research in this field was revolutionized in the early 1980s when recreational drug users who injected a badly synthesized synthetic heroin rapidly developed severe Parkinson’s-like symptoms due to it being contaminated with MPTP, an agent whose active metabolite (MPP+) specifically targeted those neurons, making it possible to reliably model Parkinson’s in laboratory animals. This was followed by the realization that one herbicide (paraquat) was very similar to MPP+, another pesticide (rotenone) also causing similar damage to neurons, a variety of pesticides being linked to a higher risk of Parkinson’s (such as organophosphates), and 6-OHDA also being able to reliably create Parkinson’s.

world needs a refactor maybe

I also love how the guy who "diagnosed" me with multiple sclerosis, first thing he insistingly pushed, was that I go get more vaccines. If a vaccine caused my brain damage why would I get more. Then for a year after that everyone is insisting such a thing is "impossible". Until I figured out the right question to ask AI and found out... Literally every study of multiple sclerosis which used rats to model its behaviour... had to induce multiple sclerosis in the rats. Guess how they did it. With a vaccine. Lol. But vaccines causing brain lesions is impossible. This multiple sclerosis doctor I went is top of his field. That's all he specializes in. You think he didn't know all the studies he was reading about his specialty induced multiple sclerosis in rats using vaccines? He wasn't young either. Like 40s. Maybe he didn't even bother to read any science; probably too busy attending pharma conferences to know what other 40k a year drugs to push on his disabled patients that he milks instead of helping.
