does this mean anal sex could theoretically transmit Alzheimer's?

  Extremely unlikely and you'd have to be doing a threesome+. Gut bacteria are present throughout the entire digestive tract, and you can't really reach very far into the anus no matter what you've got.

  It really depends on what you mean by that. In terms of this article, the gut biome would have to be changed by that. There are definitely different things people do in preparation for anal sex that could change that environment but I'm not sure how much anal sex itself actually changes that. This doesn't account for STDs that have been known to involve the nervous system for a long time already.
