This major COVID symptom is linked to brain damage
Why do people suffer from loss of smell?

Loss of smell — a major COVID-19 symptom since the beginning of the pandemic — appears to be linked to damage in the brain, a new study has found.
Why it matters: Loss of smell is one of the major telling signs of the coronavirus, impacting thousands of people every day.
The coronavirus has also been found to cause brain damage in some patients.
Linking the two major symptoms together can tell researchers and medical experts a lot about the virus.
What they found: Researchers said in a new study that they found a possible reason for the loss of smell COVID-19 symptom, according to Forbes.
The study, published in the medical journal JAMA Neurology, found that COVID-19 patients often had damaged blood vessels and axons — which are nerve cells that communicate with other cells — in the part of the brain that processes smell, per Forbes.
Damage to axons and microscopic blood vessels was more severe in patients with COVID-19 than in other people.
COVID-19 patients who said they had changes to their sense of smell were affected more by the damage to axons and blood vessels.
