KRON 4 | Smell Test to Detect Brain Disease

KRON 4 Smell Test 4

A simple smell test could provide a quick and inexpensive way to identify those at high risk for Alzheimer’s and Parkinson’s. Weekend anchor Marty Gonzalez on “KRON 4 Morning News Weekend” is a willing test subject for the Alzheimer’s peanut butter test.

Smell Test Protocol

Testing for Alzheimer’s disease or other dementias can be time-consuming, costly and invasive. In contrast, this University of Florida study used a simple peanut butter test:

  1. Patient: Closed his/her eyes and mouth. Then blocked one nostril.
  2. Clinician: Opened the peanut butter container (one tablespoon).
  3. Clinician: Held the ruler next to the open nostril while the patient breathed normally.
  4. Clinician: Moved the peanut butter up the ruler one centimeter at a time during the patient’s exhale until the person could detect an odor.
  5. Clinician: Recorded the distance.
  6. After 90 seconds, the procedure was repeated on the other nostril.

Left-Right Asymmetry

  • In patients with other kinds of dementia, there were either no differences in odor detection between nostrils or the right nostril was worse at detecting odor than the left one.
  • When smelling the peanut butter, the left nostril in the Alzheimer’s patients could not detect the smell of the peanut butter until it was an average of 10 centimeters (about 4 inches) closer to the nose than the right nostril had detected the smell. *A normally functioning olfactory nerve can detect odors at about 20 centimeters (about 8 inches) from the test agent.

*  See your physician if you lose your sense of smell. *

Validated Five-Item Test for Dementia

During a five-year follow-up, those that could not identify at least four out of the five odors were found to be more than twice as likely to develop dementia.

Testing for Alzheimer’s with Peanut Butter?

VIDEO: Here’s a brilliant use of peanut butter…. to diagnose early stage Alzheimer’s disease. According to University of Florida Health researchers, all you need is a tablespoon of peanut butter and a ruler.

Why Test Your Nose for Alzheimer’s?

brain_content_600x386The ability to smell is associated with your first cranial nerve (the olfactory nerve) which is one of the first parts of your brain to deteriorate in Alzheimer’s disease. This nerve is located in your temporal lobe and that’s also where new memories are formed. Being unable to capture new information and remember it later is characteristic of Alzheimer’s disease.
