Sniffing Out Dementia

Our noses and eyes may reveal early signs of the most common type of dementia afflicting over 5 million Americans, according to research presented this week at the Alzheimer's Association International Conference 2016.

4 new studies represent "a positive step forward to earlier detection and intervention," said Heather Snyder, director of medical and scientific operations of the Alzheimer's Association.

Although odor identification testing may prove to be a useful tool in helping physicians counsel patients concerned about their risk of memory loss, it was a retinal study that most interested David Knopman, a neurologist at the Mayo Clinic, "because if amyloid can be imaged in the eye, it might be far simpler than doing a PET scan."
