Reduced Olfactory Memory Performance Is Associated with Executive Function Deficits in Older Adults.
Introduction: Previous research has identified an association between olfactory impairment (reduced odor sensitivity/ identification/ discrimination) and cognitive impairment in older adults. The present study focused on the relationship between olfactory memory performance and cognitive/affective functioning.
Method: Recognition performance for olfactory and visual stimuli (control condition) was tested through a matching task in older adults (n = 44; Mage = 76 years) and younger adults (n = 56; Mage = 24 years). Additionally, negative affect (anxiety, depression) and cognitive functioning were assessed via validated questionnaires and a neuropsychological test battery.
Results: The older participants performed worse than the younger adults in the olfactory memory task. In older adults, difficulties in remembering odors were associated with reduced odor identification and executive functioning (reduced cognitive flexibility). Affective well-being was not related to olfactory memory performance.
Implication: Olfactory memory impairment in older adulthood might be a marker for cognitive decline in areas related to executive functions.
期刊介绍：
Experimental Aging Research is a life span developmental and aging journal dealing with research on the aging process from a psychological and psychobiological perspective. It meets the need for a scholarly journal with refereed scientific papers dealing with age differences and age changes at any point in the adult life span. Areas of major focus include experimental psychology, neuropsychology, psychobiology, work research, ergonomics, and behavioral medicine. Original research, book reviews, monographs, and papers covering special topics are published.
