The Lyon Clinical Olfactory Test: Validation and Measurement of Hyposmia and Anosmia in Healthy and Diseased Populations

The LCOT is a self-administered test designed to assess olfactory deficits. Altogether, 525 subjects contributed to the validation. Elderly participants were well represented in this sample. In a validation study (study 1), 407 healthy and 17 anosmic volunteers between 15 and 91 years of age underwent threshold, supraliminal detection, and identification testing. Cutoff values for normosmia and hyposmia were calculated and applied in a second study in a group of patients with smell complaints and in a group of Alzheimer patients with age-matched controls. Incidence of smell deficit was estimated at 5.6% in the healthy population of study 1, and at 16% in the elderly control group of study 2. Assessment of the ability of each subtest to discriminate between groups showed that LCOT is relevant to differentiating between perception and identification deficits and between Alzheimer's and hyposmic patients

Olfactory rehabilitation : Benefits of a multi-professional care

Près d’un français sur cinq souffre de troubles de l’odorat (TO), ou dysosmie. Cette prévalence a augmenté depuis l’apparition de la COVID-19 dont la dysosmie est un symptôme très fréquent et possiblement persistant. Pourtant, la prise en soin des personnes dysosmiques reste insuffisante. Cet article ouvre des pistes pour développer les rééducations olfactives (RO) sur la base de protocoles déjà éprouvés, mais aussi pour améliorer l’accompagnement des patients dysosmiques. Pour cela, une stratégie de prise en charge pluri-professionnelle est préconisée, alliant l’intervention de scientifiques, de médecins (généralistes, ORL) et de professions paramédicales.publishe
