Medical New Alzheimer's Treatment Clears Plaques From Brains of Mice Within Hours

[Borg]

I've been reading a bunch of articles in this month's Scientific American on Alzheimer's and ran across this article in a web feed that I subscribe to. The SA articles that I've read so far have touched on issues with the blood-brain barrier but this appears to be a novel approach to the problem - fix the exit ramp and the brain clears out the plaques.

The original paper:
Rapid amyloid-β clearance and cognitive recovery through multivalent modulation of blood–brain barrier transport

Assuming the mouse is a good model for humans, the very clear implication is that the amyloid deposits are likely normal and the failure of their routine removal is what's pathogenic.
