Unfortunately a lot of sites have ditched support for RSS over the past 10 years requiring tedious work arounds if you can get it to work at all.

I hope it can make a comeback but I’m dubious.

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.
