A Possible Alzheimer's Drug?

ScienceDaily, via nc links:

Neuroscientists at Case Western Reserve University School of Medicine have made a dramatic breakthrough in their efforts to find a cure for Alzheimer's disease. The researchers' findings, published in the journal Science, show that use of a drug in mice appears to quickly reverse the pathological, cognitive and memory deficits caused by the onset of Alzheimer's. The results point to the significant potential that the medication, bexarotene, has to help the roughly 5.4 million Americans suffering from the progressive brain disease. Bexarotene has been approved for the treatment of cancer by the U.S. Food and Drug Administration for more than a decade. These experiments explored whether the medication might also be used to help patients with Alzheimer's disease, and the results were more than promising.
Alzheimer's disease arises in large part from the body's inability to clear naturally-occurring amyloid beta from the brain. In 2008 Case Western Reserve researcher Gary Landreth, PhD, professor of neurosciences, discovered that the main cholesterol carrier in the brain, Apolipoprotein E (ApoE), facilitated the clearance of the amyloid beta proteins. Landreth, a professor of neurosciences in the university's medical school, is the senior author of this study as well.

The ability to limit the damage of Alzheimer's would be amazing.  After having two grandmothers slowly slide into dementia, I don't look forward to that phase of life.
