Not plaque??

"Scientists once thought plaques were bad. New studies show they may protect the brain," AARP/Bulletin, September 2010.

A whole new way of thinking what may cause Alzheimer's. It has been presumed for some time that the brain is destroyed by sticky plaque; now the thinking is that the plaque may be trying to protect the brain from clumps of protein. Why do we care? Because that will change the direction of research and the medications. Right now the medications are designed to target the plaque; but if the plaque is helpful and the protein the problem, medications will take a whole new approach. Something for all of us dealing with dementia to watch.
