The Alzheimer’s disease is the most common form of dementia. There isn’t any cure for Alzheimer’s and sooner or later it causes death. It’s predicted that by 2050 the disease would affect 1 in every 85 people over the world.
Jennifer Stamps, a graduate student from the University of Florida, found a way to predict if the patient is going to get Alzheimer’s. Stamps came up with the idea for the Peanut Butter Sniff Test. The peanut butter is a pure odorant, thus it’s easy to access the olfactory nerve of the human body. The sniffing test includes a metric ruler and 14 grams of peanut butter which is approximately one tablespoon full.
During the test the patient is asked to keep their eyes and mouth closed and one of their nostrils is blocked. The doctor measures the distance from which the patient can smell the butter. This process is repeated with the other nostril after 90 seconds. Usually, if the results show that the patient’s left nostril is worse at detecting the odor, it’s a clear sign they could be suffering from Alzheimer’s.
The unusual test also shows signs of other kinds of dementia.
