NEWNow you can hearken to Fox Information articles!
COVID-19 could cause the mind to shrink, cut back gray matter within the areas that management emotion and reminiscence, and harm areas that management the sense of odor, an Oxford College research has discovered.
The scientists stated that the results have been even seen in individuals who had not been hospitalized with COVID, and whether or not the impression may very well be partially reversed or if they might persist in the long run wanted additional investigation.

“There’s sturdy proof for brain-related abnormalities in COVID-19,” the researchers stated of their research, which was launched on Monday.
Even in gentle instances, contributors within the analysis confirmed “a worsening of government operate” accountable for focus and organizing, and on a mean mind sizes shrank between 0.2% and a pair of%.
COVID-19 INFECTION CAUSES MENTAL HEALTH ISSUES, EATING DISORDERS: STUDIES
The peer-reviewed research, revealed within the Nature journal, investigated mind adjustments in 785 contributors aged 51–81 whose brains have been scanned twice, together with 401 individuals who caught COVID between their two scans. The second scan was carried out on common 141 days after the primary scan.
The research was performed when the alpha variant was dominant in Britain and is unlikely to incorporate anybody contaminated with the delta variant.
Research have discovered some individuals who had COVID suffered from “mind fog” or psychological cloudiness that included impairment to consideration, focus, velocity of data processing and reminiscence.
The researchers didn’t say if vaccination towards COVID had any impression on the situation however the UK Well being Safety Company stated final month {that a} assessment of 15 research discovered that vaccinated individuals have been about half as more likely to develop signs of lengthy COVID in contrast with the unvaccinated.

What to know about the new 'FLiRT' COVID variants
- According to the World Health Organization, the “FLiRT” variants of the SARS-CoV-2 coronavirus have been the dominant forms of the virus circulating globally this year.
- “FLiRT” is an acronym for the locations of the mutations the variants share on the virus’ spike protein.
- CDC data suggests COVID-related hospitalizations have trended downwards in recent weeks and the number of patients in emergency departments who have tested positive for COVID has been about flat for the past month.
The so-called FLiRT variants of SARS-CoV-2 coronavirus that cause COVID-19 have been the dominant forms of the virus circulating this year globally, according to the World Health Organization.
The moniker FLiRT is an acronym for the locations of the mutations the variants share on the virus’ spike protein. One of them, called KP.2, has become the most commonly circulating variant in the United States over the past month, according to the U.S. Centers for Disease Control and Prevention.
Here is what you need to know about FLiRT.

HOW ARE THE FLIRT VARIANTS DIFFERENT FROM PREVIOUS VARIANTS?
The FLiRT variants, which also include KP.2’s “parental” lineage JN.1, have three key mutations on their spike protein that could help them evade antibodies, according to Johns Hopkins University.
ARE THE FLIRT VARIANTS MORE CONTAGIOUS OR LIKELY TO CAUSE MORE SEVERE ILLNESS?
Dr. Aaron Glatt, chief of infectious diseases at Mount Sinai South Nassau Hospital in Oceanside, New York, and a spokesperson for the Infectious Diseases Society of America said he has not seen evidence of an uptick in disease or hospitalizations, based on the data he tracks and experience with his own patients.
“There have been some significant changes in the variants, but I think in recent times it’s not been as important, probably because of the immunity many, many people already have” from prior illness and vaccination.
CDC data suggests that COVID-related hospitalizations have trended downwards in recent weeks and the number of patients in emergency departments who have tested positive for COVID has been about flat for the past month.
Data suggests that COVID rates are also down year-over-year. The rate of COVID hospitalizations is less than half than a year earlier, and the amount of the antiviral Paxlovid currently being prescribed for COVID-19 is down around 60% from last year, according to analyst notes.
DO CURRENT VACCINES WORK AGAINST THE FLIRT VARIANTS?
The current vaccines should still have some benefit against the new variants, Glatt said.
Since 2022, health regulators have asked vaccine makers to design new versions of the COVID-19 vaccines to better target circulating variants. Last month, Europe’s regulator said vaccine makers should target the JN.1 variant. U.S. experts and regulators will meet to discuss vaccine design on June 5 after having postponed the meeting from May 16 in order to have more time to “obtain surveillance data and other information.”
Makers of vaccines based on messenger RNA (mRNA) technology – Pfizer with partner BioNTech, and Moderna – say they are waiting for the June 5 meeting before settling on the design of their next vaccines.
Novavax, which makes a more traditional protein-based vaccine that takes longer to manufacture, has begun producing a shot targeting JN.1 consistent with recommendations from European regulators.
