Are SuperAgers Super‐Sniffers? Performance on the NIH Toolbox Odor Identification Test in cognitive SuperAgers
Preliminary findings based on NIHTB-OIT performances suggest that SuperAgers demonstrate stronger odor identification abilities compared to their cognitively average peers, possibly due to the integrity of the memory-related limbic system that includes the olfactory system. Further exploration of olfaction and other sensory functions in SuperAging may augment the biological signature of exceptional memory performance in old age.
