New Alzheimer's drugs show promise

July 15, 2009 A drug called Dimebon appears to improve cognitive function in both mice and humans. New research also reveals it actually increases brain levels of a protein long thought to be a culprit in the disease.

Also, a vaccine has had some effect in reducing the number of certain protein tangles that are also associated with Alzheimer's.

Right now scientists are still trying to determine what to do with the findings but say they could play a role in helping to unravel how to treat Alzheimer's disease.
