How does Alzheimer’s disease affect the brain?

In Alzheimer’s, fragments of a protein called amyloid form abnormal clusters called plaques between brain cells, and a protein called tau forms tangles inside nerve cells. It seems likely that damage to the brain starts a decade or more before memory and other cognitive problems appear.
