There are measurable links between use of ADD/ADHD medication and Parkinson’s, which makes sense given that the former modulates dopamine and the latter has to do with dopamine modulation.

I view this direct connection as more compelling an explanation.

This may be true in the future but seems unlikely today, Parkinson's rarely occurs before 60 and the rise in ADHD diagnoses started in the 90s.

[franklyt]

Yeah, we'd need more data. Because PD is such a low-incidence disease generally, any kind of uptick, even in the pre-60 cohort, would push the dial substantially. Are pre-60 cases, which I just found out trivially are at 4%, increasing substantially? Is 4% inclusive of a much older dataset? I'd venture that the answer is yes, but I have no idea.

Wait till you see what anti-psychotics can do.

[franklyt]

Errr... I was more implying that ADD/ADHD medications are in very common usage, making it a notable data point. Perhaps I should have make that explicit.
