We don’t think much about our sense of smell. But new research done with mice reveals that the loss of smell could give us clues to the beginnings of Alzheimer’s disease. About 5.3 million people in the U.S. are living with Alzheimer’s (Alz.org, 2009). It is a devastating disease that adds to our health care costs, especially with our growing elderly population.
Check with your doctor if you notice a change in your sense of smell. He or she may order an olfactory test (less expensive) before a CT scan to determine the cause.
