Cancer drug reverses Alzheimer's symptoms in mice, study says

A drug that has been approved for the treatment of a type of skin cancer since 1999 appears to reverse Alzheimer's symptoms -- in mice.

Case Western Reserve University School of Medicine neuroscientist Gary Landreth and colleagues reported Thursday that bexarotene quickly cleared away beta-amyloid plaque, believed to cause the cognitive deficits of Alzheimer's disease, from the brains of genetically engineered mice.
