Effect of Worry Level on Recall Memory for Odors in ApoE-ε4 Carriers and Non-Carriers

摘要

Objective:Increased levels of worry, age, and presence of the apolipoprotein-E (ApoE) ε4-allele are associated with risk for developing cognitive declines and Alzheimer’s disease (AD). Odor memory performance has been shown to vary as a function of age and ApoE-genotype, and odor memory tests are sensitive to pre-clinical AD. Worry is known to influence verbal memory; however, its effects on odor memory are unknown. This study aimed to assess the relationships between worry, age, and ε4-status on odor memory.
