Long COVID smell loss linked to changes in the brain

"The findings suggest smell loss, known as anosmia, caused by long COVID is linked to a change in the brain that stops smells from being processed properly"

I recovered from COVID but my nose didn't. Here's how I cope

"Roughly 5% of people who experience smell loss during COVID-19 will develop long-term anosmia, according to Dr. Bradley J. Goldstein, an ear, nose and throat doctor at Duke University Hospital.

The impact is more drastic than most people realize."
