You Can Detect Alzheimer's With A Peanut Butter Test
Not only is peanut butter a main component for the classic PB&J;, it has proven to be helpful in the medical field. Specifically, peanut butter has been used in tests to detect early stages of Alzheimer's disease. The neuroscientists that developed the diagnosis test explains that the olfactory cortex (the area of the brain that processes smell) is the first part of the brain to deteriorate in Alzheimer's. The test involves a jar of peanut butter and a ruler, and his performed on each nostril. If the left nostril is significantly worse at detecting a certain smell-in this case, the smell of peanut butter-than the right one, then it may be a sign of Alzheimer's.
