MedPage Today Self-reported problems with thinking, concentrating more likely in those with olfactory issues. The vast majority of people reporting dips in their ability to smell 2 years after COVID-19 had olfactory dysfunction when formally tested, findings from NIH’s RECOVER Consortium showed. And surprisingly, most people who didn’t believe they had any post-infection changes in smell had measurable dysfunction as well.
Among participants reporting a loss in smell or change in smell after COVID, 79.8% had hyposmia on formal testing using the University of Pennsylvania Smell Identification Test (UPSIT), including 23% with severe microsmia or anosmia, according to researchers led by Leora Horwitz, MD, MHS, of NYU Grossman School of Medicine in New York City.
