Scenting and Cognitive Performance (09-05-23)
Woo and colleagues studied the cognitive implications of nighttime scenting; it is possible that their findings are useful in other contexts. The investigators report that “Male and female older adults . . . age 60–85, were enrolled in the study and randomly assigned to an Olfactory Enriched or Control group. Individuals in the enriched group were exposed to 7 different odorants a week, one per night, for 2 h, using an odorant diffuser. Individuals in the control group had the same experience with de minimis amounts of odorant.
