A New Diagnostic Test for Alzheimer's is More than a Wee Bit Nutty
Smelling peanut butter may soon become the go-to method for determining whether a patient suffers from the heartbreaking condition

After conducting controlled experiments with patients suffering from varying forms of cognitive impairment wherein they were instructed to smell peanut butter from various distances and through alternating nostrils, Researchers from University of Florida's McKnight Brain Institute Center for Smell and Taste, were able to ascertain that "patients with early-stage Alzheimer's had much more difficulty smelling the aroma, particularly through their left nostril, than those without the disease." (Curious as to how the testing was conducted? Watch the surprisingly informative video below.)
What's so exciting about these findings, aside from the simplicity of having someone just having to take a whiff, is how wallet-friendly the procedure is. Other diagnostic tests are time consuming, invasive, exhausting and expensive -- so expensive that often times patients opt out of them, delaying their diagnosis and the imperative care they require.
"At the moment," says lead researcher Jennifer Stamps in a statement, "We can use this test to confirm diagnosis. But we plan to study patients with mild cognitive impairment to see if this test might be used to predict which patients are going to get Alzheimer's disease."
