Sense of smell can be altered for 5 months or more after acute SARS-CoV-2 infection, Canadian researchers reported. Nearly one in five healthcare workers who had a compromised sense of smell when they ...

Insulin plays a critical role in the maturation, after injury, of immature olfactory sensory neurons. Applying insulin into the nasal passage could be developed as a therapy for injury caused by a ...

Patients with chronic rhinosinusitis (CRS) with nasal polyps exhibited significant improvement in olfactory function when treated with a combination of oral and nasal steroids vs nasal steroids alone.

Chronic rhinosinusitis (CRS) often leads to olfactory dysfunction, diminishing quality of life and daily satisfaction with taste and smell. Improvement of olfactory function in CRS is a key ...

Numerous studies to date have shown that olfactory receptors are relevant not only for smell perception, but that they also play a significant physiological and pathophysiological role in all organs.

Searching for new ways to help my senior patients improve and maintain cognitive functions, I came across an interesting research study from the University of California Irvine (Woo, C. et al. 2023) ...

Olfactory sensory neurons are nasal neurons that make use of hundreds of different types of odorant receptors to analyze odorous chemicals in our external world and send that information to our brain.

Exposure to ultrafine particles from traffic alters the expression of many genes in human olfactory mucosa cells, a new study shows. The study is the first to combine an analysis of emissions from ...

Problems with the sense of smell appear to be an early indicator of cognitive decline in people with type 2 diabetes. However, it's unknown whether factors such as diet and obesity play a role in who ...

Olfactory dysfunction in MS may be linked to nasal microbial changes, not just central inflammation. MS patients showed lower olfactory test scores and distinct nasal microbiome differences compared ...
