The peanut butter test is a diagnostic test which aims to detect Alzheimer's disease by measuring subjects' ability to smell peanut butter through each nostril.
 The test was originally reported in October 2013 by researchers from the University of Florida's McKnight Brain Institute, led by professor Kenneth Heilman, and involves measuring the ability of patients to smell peanut butter held close to their nose.
 The researchers concluded that patients with Alzheimer's were not able to smell the peanut butter as well through their left nostril as their right one.
 The study's lead author, graduate student Jennifer Stamps, got the idea for the study when, while studying under Professor Heilman, she noticed that none of his patients had been tested for their sense of smell.
 The idea of using peanut butter came to Stamps when she administered it to patients as part of a routine test of cranial nerve function.
 Their decision to use it was also motivated by the fact that it is a pure odorant (i.e. is only detected by the olfactory nerve), and that Heilman had told Stamps, "If you can come up with something quick and inexpensive, we can do it."
