It is estimated that at least 60% of people infected with COVID-19 suffer from anosmia, which is a partial or complete loss of smell.
Some acquire their meaning later, but others do not. About 10% of patients will have persistent symptoms that are part of a post-covid syndrome (commonly referred to as “long covid”).
A team of researchers from the University of Quebec at Trois-Rivières, in collaboration with the doctors of Siusu
Olfactory training for olfactory disease after COVID-19.
Wrong perception of smell
Among them, resident doctor Claudia Demers states that victims of COVID-19 not only notice a decrease or decrease in smell or taste, but also a misconception of known odor.
What we hear more and more are the foul smelling, bleach, very strong smell, and which can suddenly happen without even smelling anything, which is called phantom., Explains Claudia Demers.
For its part, parosmia, which is a change of taste and smell, we are also informed, that is, people who smell something that they have never felt before or who no longer smell, e.g. For, coffee that smells of bleach.
The study focuses on people suffering from an olfactory change that persists for more than two months.
There are participants who find it extremely difficult to live with it, for example florists. Others who say they have had eating disorders, who have difficulty eating, which also have an effect on morale., The researcher continues.
The team of the study’s principal investigator, Johannes Frasnelli, began recruiting last fall. Training involves sniffing essential oils for five minutes, twice a day, alternating morning and evening for a period of 12 weeks.
Fragrance training existed long before COVID-19. It has been used for other infectious olfactory diseases. There are several studies that have shown benefit in up to 30% of patients, a significant improvement. This is no miraculous cure, but we have nothing to lose in the sense that there is currently no recognized treatment for COVID for Anosmia Secondary., Belong to Claudia Demers.
Candidates are given four types of fragrances, namely, floral (rose), fruit (lemon), fragrant (clove) and resin (eucalyptus).
It has been studied in the past with these four odors. We wanted to ensure standardization of the treatment to see if it also works with COVID-19, Adds Claudia Demers.
The goal is to try to regenerate cells that have been damaged by the COVID-19 virus.
