Scientists have come up with a cheap and non-invasive way to determine if someone might be suffering from the effects of Alzheimer’s disease.
According to research from the University of Florida, one way of testing someone to see if they have Alzheimer’s disease is to have them smell peanut butter.

Loss of the sense of smell is apparently one tell tale sign of the onset of the potentially debilitating disease that is known to negatively affect cognitive function in various ways including sensory perception and memory.

Researchers had study subjects plug one nostril, and then the other while they smelled peanut butter from varying distances.

Sense of smell in the left nostrils of the subject group that had been diagnosed with Alzheimer’s disease was significantly impaired compared with a control group and another group suffering from different cognitive ailments.

The Alzheimer’s link is specific to the olfactory sense and researchers used peanut butter to test the subject’s sense of smell because it is purely olfactory and does not give off a trigeminal sensation like stinging or burning as many other scents do.
