The sniffing bead system, an olfactory dysfunction screening tool for geriatric subjects: a cross-sectional study.

ABSTRACT:

Background

This study aimed to develop a simple and one-off olfactory screening test, the sniffing bead system, for general clinical use in older adults.

Methods

In this cross-sectional study, geriatric subjects (aged > 50 years) who underwent neurocognitive and olfactory function tests were included. Overall, 137 subjects were enrolled, and the study was conducted at Chung-Ang University, Seoul, Korea. Olfactory function was measured by obtaining the scores of the sniffing bead system using 2-phenylethyl alcohol, n-butanol, and the YSK olfactory function test. Time taken for each olfactory function test was also measured.

Results

The score of the 2-phenylethyl alcohol sniffing bead test was 2.58 ± 1.52, which was significantly associated with the YSK_threshold (2.41
