We need to start letting people and organisations know that this isn’t acceptable. I’ve been guilty of just using an anonymous account or letting it slide but having a mailing list is not much effort for example, honestly having a basic website is pretty cheap and easy.
Haven’t dug into the data but from reading this article it seems like having untreated diseases/poor health in general increases the risk of dementia rather than these classes of drugs directly reduce risk.
I’d also suggest that being vaccinated and being prescribed these medications is correlated with being in regular contact with the healthcare system which may be the more relevant factor.
