Cancer Med Works Wonders Against Alzheimer's in Mice

Bexarotene removes plaque built up on brain

(Newser) - Scientists were "shocked and amazed" at the effects of a common cancer drug in battling Alzheimer's in mice. The disease causes a buildup of plaque in the brain—but just hours after mice received bexarotene, the plaque began to disappear and the mice got smarter, AFP reports. The... More »

MRIs Hold Promise of Early Alzheimer's Detection

Brain plaque spotted in rabbits

(Newser) - Researchers are a step closer to early diagnosis of Alzheimer's disease using conventional MRI scanners. Plaque associated with Alzheimer's has been detected in rabbits by a team in Canada using MRI equipment, Reuters reports. Currently, the disease is diagnosed based on a series of tests, but a diagnosis can only... More »
