The University of Chicago conducted an eight-year study where participants underwent olfactory testing, identifying 12 common scents. Those who scored below a certain threshold were found to have a higher risk of developing Alzheimer’s disease. This simple, non-invasive test proved to be a valuable tool in predicting cognitive decline.
Dr. Jeffrey Motter, co-author of the study, emphasized the potential of incorporating such olfactory assessments into routine medical check-ups. Given their simplicity and cost-effectiveness, these tests could become a standard part of early Alzheimer’s screening, allowing for timely interventions.
