For a before-and-after comparison, researchers invited 394 COVID-19 survivors to come back for follow-up scans as well as 388 healthy volunteers.

Among the COVID-19 survivors, researchers saw "significant" loss of gray matter in regions of the brain related to smell and taste - the left parahippocampal gyrus, left orbitofrontal cortex and left insula.

The authors said more research is needed to determine whether COVID-19 survivors will have issues in the longer term with their ability to remember emotion-evoking events.

Delta variant fuels steep rise in England COVID-19 prevalence.

The rapid spread of the extremely contagious Delta coronavirus variant, first identified in India, has driven a 50% rise in COVID-19 cases in England since May, researchers at Imperial College London said on Wednesday in their latest report from the REACT-1 prevalence survey.

On Friday, the World Health Organization said the Delta variant is becoming the globally dominant variant of the disease.

To make copies of itself, or replicate, inside infected cells, the virus activates a cellular response called the "unfolded protein response," explained Nerea Irigoyen of the University of Cambridge.

In laboratory experiments, the researchers inhibited activation of this cellular response using experimental drugs.

The unfolded protein response in infected cells "might be responsible at least to some extent" for some of the complications associated with COVID-19, such as respiratory distress and thickening and scarring of lung tissues, Irigoyen said.

Organ transplant recipients may not respond adequately to two-dose COVID-19 vaccines, but a third shot can sometimes be the charm, researchers said.
