Background: Olfactory dysfunction is common in older individuals. The importance of such dysfunction to individuals is highly variable: many people do not seem to care about their olfactory dysfunction, others suffer and complain about problems in daily life, a reduced quality of life, or symptoms of depression.
Objective: Understanding the importance of olfaction for different age groups in normosmic as well as in smell-disordered subjects may help to find reasons for insufficient coping with olfactory dysfunction.
Methods: We used a questionnaire to capture the individual importance of olfaction in a sample of 433 normosmic and 172 dysosmic people from 15-82 years of age. Furthermore, all participants underwent standardized assessment of olfactory function.
Results: The importance of olfaction was highest in the group of young (≤25-year-old) normosmic women. Dysosmia was associated with a decreased importance of olfaction, irrespective of age. However, 18 % of the dysosmic patients showed a tendency to aggravate their symptoms. This high degree of aggravation could not be explained by sex, age, or severity of olfactory dysfunction.
Conclusions: The high importance of olfaction observed in young women may reflect the specific needs of this group, such as mate selection and child care. The strongly reduced importance of olfaction in dysosmic subjects seems to serve as an adaptive coping mechanism. A tendency to aggravate symptoms may indicate insufficient coping. Hence, detecting high aggravation could be a first step to recognizing high psychological strain and the need for psychotherapeutic treatment.

Target odorant detection in mixtures has been shown to become more difficult as the number of background odorants increases and falls below chance level in mixtures with 16 components. Our aim was to investigate target odorant detection in mixtures among healthy people and compare it between dysosmic patients and age- and gender-matched controls. Participants underwent extensive olfactory testing and performed two target odorant detection tasks.

Purpose: Assessing olfactory function is highly significant in clinical practice, particularly in the context of the recent COVID-19 pandemic. Recent approaches in this field emphasize the importance of reducing the time and cost devoted to olfactory testing procedures. Hence, the aim of the present study was to examine the reliability and basic characteristics of Digital Scent Device 20 (DSD-20), an innovative olfactory test consisting of 20 "universal odors", in a European population.

The partial or complete loss of the sense of smell, which affects about 20% of the population, impairs the quality of life in many ways. Dysosmia and anosmia are mainly caused by aging, trauma, infections, or even neurodegenerative disease. Recently, the olfactory area-a site containing the olfactory receptor cells responsible for odor perception-was shown to harbor a complex microbiome that reflects the state of olfactory function.

Background: Although dysosmia affects a significant proportion of the adult population, there are a paucity of studies addressing its impact on flavor perception and food enjoyment. This study aimed to assess flavor perception and food enjoyment in subjects with and without dysosmia, comparing performance of items considered olfactory-dominant or trigeminal-dominant.
Methods: Adult subjects prospectively underwent Sniffin' Sticks olfactory testing from which threshold, discrimination, and identification (TDI) scores were used to identify dysosmic (TDI over 31) and normosmic subjects (TDI under 31).

Purpose: The prevalence of long-term olfactory and gustatory dysfunction in participants suffering from sudden chemosensory loss due to coronavirus disease 2019 (COVID-19) is unknown. Furthermore, evaluations of the reliability of participants' self-reporting of olfactory function (SOF) and gustatory function (SGF) using extended objective psychophysical testing are missing.
Methods: In this population-based cohort study in a PCR-tested community in Thuringia, Germany, olfactory function was extensively examined 4 months after a COVID-19 outbreak using the "Sniffin Sticks" test battery to determine the TDI score, i.
