Abstract

<p>　The purpose of this study was to evaluate Open-Essence (OE), an odor identification test card, as a new screening tool to detect age-related changes in olfaction. We analyzed the correct answer rates for 12 odors between a group of healthy volunteers aged under 50 years old (<50 years age group; n=43), and a healthy group of healthy volunteers aged 50 years old or older (≧50 years age group; n=50). As we expected, the average total score in the ≧50 years age group was lower than that in the <50 years age group (10.04 vs 7.06, p<0.001). ROC analysis proved that a combination of 3 odors including Menthol, Japanese Orange and Condensed Milk in the OE showed the highest sensitivity and specificity for detection of age-related changes in olfaction. These results indicate that OE is a useful screening tool to detect age-related changes of olfaction.</p>
