Abstract [en]

he purpose of this study was to determine correlates of odor identification in old age. One hundred and thirty-two men and women (60-91 years) were assessed in a number of tasks tapping sensory acuity (i.e., odor sensitivity, intensity discrimination, quality discrimination) and different cognitive abilities (i.e., perceptual speed, executive functioning, verbal fluency). Hierarchical regression analyses revealed that age, female sex, olfactory sensitivity, quality discrimination, cognitive speed, and verbal fluency were the most potent correlates of odor identification in general. In addition, the age-related variance in odor identification was eliminated when age-related deficits in odor sensitivity, quality discrimination, and perceptual speed were taken into account. This pattern of outcome suggests that age-related differences in these abilities underlie the well-established age impairment in odor identification.
