Olfactory function is preserved in about a quarter of patients with Parkinson’s disease (PD), and may be predictive of disease course, say researchers. Olfactory testing has been used as a screening ...

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.

As humans age, particularly after middle age, their brain functions, cognitive abilities and memory can deteriorate to varying degrees. Aging-related disorders marked by cognitive decline, ...

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.

This new study evaluated outcomes following add-on dupilumab to treat severe uncontrolled chronic rhinosinusitis with nasal polyps (CRSwNP). Dupilumab was shown to improve olfaction impairment (OI) in ...

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 ...

A review of more than 200 studies reveals that olfactory receptors--proteins that bind to odors that aid the sense of smell--perform a wide range of mostly unknown functions outside the nose. The ...

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) ...

Ultrafine particles, UFPs, the smallest contributors to air pollution, hinder the function of mitochondria in human olfactory mucosa cells, a new study shows. The study showed that traffic-related ...

It has been almost a decade since the Deepwater Horizon Oil spill. Described as the worst environmental disaster in the United States, nearly 5 million barrels of crude oil oozed into the Gulf of ...
