As neuroimaging technology continues to be researched as a tool for early diagnosis of Alzheimer’s disease, researchers at the University of Florida (UF), Gainesville, have been investigating a much more low-tech alternative requiring only a ruler and a dab of peanut butter.

UF graduate student Jennifer Stamps devised an odor detection test that revealed patients in the early stages of Alzheimer’s disease had a harder time recognizing the smell of peanut butter using only their left nostril, requiring it to be much closer to their noses, but had no problem when using their right nostril.
