Meanwhile, OP posted an article at the same time saying that amyloid proteins don't actually seem to be related to Alzheimer's: https://www.sciencedaily.com/releases/2025/11/251111005944.htm

That article reports that a drug targeted at clearing amyloid proteins didn’t suffice to restore the brain’s waste-clearing functionality; this article reports that a drug targeted at repairing the blood-brain barrier does restore waste-clearing functionality (including amyloid proteins). So they’re not completely contradictory.
