A dollop of peanut butter and a ruler can be used to confirm a diagnosis of early stage Alzheimer's disease, University of Florida Health researchers have found.
Jennifer Stamps, a graduate student in the University of Florida (UF) McKnight Brain Institute Center for Smell and Taste, and her colleagues reported the findings of a small pilot study in the Journal of the Neurological Sciences.
Stamps came up with the idea of using peanut butter to test for smell sensitivity while she was working with Dr. Kenneth Heilman, one of the world's best known behavioral neurologists, from the UF College of Medicine's department of neurology.
While shadowing doctors in Heilman's clinic, she noticed that patients were not tested for their sense of smell. The ability to smell is associated with the first cranial nerve and is often one of the first things to be affected in cognitive decline.
