New Alzheimer's Nasal Spray Clears Toxic Tangles in Human Neurons And Mice
Twisted and tangled proteins are found in the brains of many of those who die with Alzheimer's disease.

The spray targets the tau proteins that clump together in nerve cells.
It also shows promise for the Lewy bodies in dementia.
Not sure of the side effects yet (anything that powerful is bound to have some).
However this is a major advance, for both science and patients.
