Noninvasive Smell Test may Detect Early Alzheimer’s

Doctors may one day be able to test people for Alzheimer’s disease by testing their ability to identify familiar scents, like smoke, coffee, and raspberry.
In 2 studies released at an international Alzheimer’s meeting July 26, people who were in their 60s and older took a standard odor test. In both cases, individuals who did poorly on the tests were more likely to already have or go on to develop memory and thinking problems.
