Can Peanut Butter Help Detect Alzheimer’s?

A new tool for detecting Alzheimer’s disease… Peanut butter?

FOX News Radio’s Hank Weinbloom explains:

The left side of the brain …The part that recognizes and remembers smells… Is one of the first areas to falter when Alzheimer’s strikes. And so researchers at the University of Florida’s McKnight Brain Institute came up with a test. They had patients cover one nostril, and then the other, to see how strongly they can smell a cup of peanut butter. Sure enough, for patients who were later diagnosed with Alzheimer’s, the left nostril was much less sensitive to the peanut butter smell than the right.
