From the article on the Drug:
"This drug has generated all kinds of excitement because it is the first approved drug that does more than just relieve the symptoms of Alzheimer's. This drug actually affects an underlying disease process by reducing the amount of
sticky amyloid plaque that builds up in the brain. The catch is that removing this plaque may not actually help patients avoid memory loss and thinking problems. One big study showed that it did. Another showed that it didn't."
On Grape Seed Extract and this Amyloid Plaque, this is where I have been putting my money for years.
