Loss of smell and taste is strongest predictor of early COVID-19 infection

User data from a new COVID-19 symptom tracking app reveals a loss of taste and smell are the strongest predictors of a positive coronavirus diagnosis. Using the data, researchers have developed a model to identify which combination of symptoms together could best predict COVID-19 infection in individuals.

Loss of smell associated with milder clinical course and less hospitalizations in COVID-19

COVID-19 patients who reported smell loss as a symptom of their infection are ten times less likely to be hospitalized for coronavirus than those who do not report anosmia.

Loss of smell sense first sign of COVID-19

As many as one in three COVID-19 patients report smell loss as an early symptom of the infection. Researchers say the loss of smell could be used as a key clinical indicator of infection in otherwise symptom-free or pre-symptomatic carriers of coronavirus.

Mechanism Behind Loss of Smell With COVID-19 Revealed

Infection with the SARS_CoV-2 virus causes dials down the action of olfactory receptors, resulting in smell loss associated with COVID-19.

New Treatment for COVID-Induced Smell Loss

A new study presents a promising treatment for restoring the sense of smell in long-COVID patients. The study explores the effectiveness of CT-guided stellate ganglion block, a minimally invasive procedure, in treating parosmia—a condition affecting up to 60% of COVID-19 patients where the sense of smell is distorted.

Rapid Loss of Smell Predicts Dementia and Smaller Brain Areas Linked to Alzheimer’s

Smell loss in older individuals not only can predict cognitive decline, but it can also foretell structural changes in brain structures linked to Alzheimer's disease, a new study reports.

Sniffing Out the Mechanism Behind Parkinson’s Smell Loss

Up to 90% of patients report experiencing a diminished sense of smell, even prior to the onset of other symptoms of Parkinson's disease. A new study reveals the mechanism behind smell loss associated with Parkinson's, reporting mouse models with olfactory impairments had severe pathology in projection neurons of the olfactory pathway. The mice also had reduced neurogenesis in the olfactory bulb.
