In: Hayes AW (ed) Toxicology of the eye, ear, and other special senses. Among the 11,609 participants ≥19 years old, 780 had experienced olfactory dysfunction; thus, the prevalence of olfactory dysfunction was 6.3% (men, 5.8% and women, 6.7%). Olfactory dysfunction (OD), a reduced or complete absence of the ability to smell, remains underdiagnosed in the general population (1, 2) despite frequently described associations with poor health outcomes (3, 4).This applies particularly to older adults, who are at increased risk for generalized OD extending across subdomains including detection sensitivity … Tiss Cell 5: 113–131, Graziadei PPC, Monti-Graziadei GA (1983) Regeneration in the olfactory system of vertebrates.
