Peanut Butter and Alzheimer's

Came across this interesting information about a test for Alzheimer's. The test involves a jar of peanut butter and a ruler, and is performed under each nostril. If the left nostril is significantly worse at detecting the smell of peanut butter-than the right one, then it may be a sign of Alzheimer's. The olfactory cortex (part of the brain that processes smell) is the first area of the brain to deteriorate in Alzheimer's.


Peanut butter is a smell that is not typically lost as people age.
