One of the hallmarks of a COVID-19 infection has been a lost sense of smell after the infection ends.
In a new study, researchers blame an ongoing immune assault on the olfactory nerve cells — cells found at the top of the nasal cavity — and a decline in the number of those cells. The study was led by a team at Duke Health in Durham, N.C.
Could the future of dementia screening include a test of a person's sense of smell?
It may, suggests a new study that found the decline in a person's sense of smell could predict their loss of mental function and warn of structural changes in the brain that are important in Alzheimer's d...
Since the early days of the pandemic, loss of smell and taste have been tied to COVID-19 infection. But a new study shows those telltale traits are much less likely with the Omicron variant than the earlier Alpha and Delta versions of the coronavirus.
Lyss Stern lost her sense of smell when she was diagnosed with COVID-19 in March 2020, and it still hasn't returned.
Stern, 47, a New York City author and mother, has seen countless doctors and taken many types of medicine, vitamins and supplements to get her sense of smell back. She also undergoes acupuncture regularly and saw an energy healer -- all to no or very little avail.
Air pollution could cause sinus misery, new research suggests.
Specifically, tiny particulate air pollution (known as PM2.5) could contribute to chronic rhinosinusitis, a condition in which the sinuses get infected or irritated, become swollen, are severely congested and secrete mucus into the throat for 12 weeks or more.
"To our knowledge, this is the first study to report that lon...
A year on, nearly all patients in a French study who lost their sense of smell after a bout of COVID-19 did regain that ability, researchers report.
"Persistent COVID-19-related anosmia [loss of smell] has an excellent prognosis, with nearly complete recovery at one year," according to a team led by Dr. Marion Renaud, an otorhinolaryngologist at the University Hospitals of Strasbourg.
If you can't stand broccoli, celery or kale, you may be a supertaster, and it just might protect you from COVID-19.
Supertasters are folks who are highly sensitive to bitterness. They're not only less likely to get COVID-19 than people who aren't so sensitive to sharp, pungent flavors, they're also less likely to wind up hospitalized with it, the researchers said.
Add another part of your body to the list of what COVID-19 can invade: New research shows mouth cells can be infected with the new coronavirus.
Previous studies have shown that the coronavirus infects the upper airways and lungs, the digestive system, blood vessels and kidneys, which may explain the wide-ranging symptoms experienced by COVID-19 patients.
Many patients with mild to moderate COVID-19 could become "long haulers," suffering symptoms months after they clear their non-life-threatening infection, new research shows.
About 33% of COVID-19 patients who were never sick enough to require hospitalization continue to complain months later of symptoms like fatigue, loss of smell or taste and "brain fog," University of Washington (UW) r...
While loss of smell is a symptom of COVID-19, don't panic -- there are a variety of other possible causes, one expert says.
"It can be due to nasal or sinus inflammation, or other viral infections distinct from COVID-19," explained Dr. Bobby Tajudeen, director of rhinology, sinus surgery and skull base surgery at Rush University Medical Center in Chicago.
Special training may help COVID-19 patients regain their sense of smell after suffering parosmia, a new British study suggests.
Parosmia is a condition where people have strange and often unpleasant smell distortions. Instead of smelling a lemon, for example, you may smell rotting cabbage, or chocolate may smell like gasoline. Parosmia has been linked to COVID-19 and other viruses and hea...
If you're a senior who can't smell onions, smoke, chocolate or natural gas, it's time to see your doctor.
Seniors who lose their sense of smell -- which doctors call olfactory dysfunction -- have higher odds of dying from all causes within five years, new research shows. Scientists had previously found a link between olfactory dysfunction and impaired thinking and memory.
Here's a clue that you may have coronavirus that might surprise you: a loss of your sense of smell.
Groups representing ear, nose and throat (ENT) specialists in Britain and the United States have issued guidances that a sudden loss of a person's sense of smell may be a sign of infection with the new coronavirus.
It's not a completely unexpected finding, since a temporary in...
Don't blame a loss of taste on your mouth, new research suggests.
Instead, most people can thank their nose for the problem, the study authors said.
The research team at the Virginia Commonwealth University's Smell and Taste Disorders Center examined the records of 358 patients who were evaluated for a taste disorder or combined taste/smell disorder between 1980 and 2017.
