1.hour of fox, cnn or msnbc are probably more harmful to the brain than 2.covid infections.
"natural immunity" crowd
If you don't vaccinate because of hyped up fears of some vague fear of long term side effects of the vaccine, you are going to expose yourself to the long term effects of the disease.
----------------------------------------------------------------------------------------------------
With more than 18 months of the pandemic in the rearview mirror, researchers have been steadily gathering new and important insights into the effects of COVID-19 on the body and brain. These findings are raising concerns about the long-term impacts that the coronavirus might have on biological processes such as aging.
As a cognitive neuroscientist, my past research has focused on understanding how normal brain changes related to aging affect people’s ability to think and move – particularly in middle age and beyond. But as more evidence came in showing that COVID-19 could affect the body and brain for months or longer following infection, my research team became interested in exploring how it might also impact the natural process of aging.
In that study, researchers relied on an existing database called the UK Biobank, which contains brain imaging data from over 45,000 people in the U.K. going back to 2014. This means – crucially – that there was baseline data and brain imaging of all of those people from before the pandemic.
The research team analyzed the brain imaging data and then brought back those who had been diagnosed with COVID-19 for additional brain scans. They compared people who had experienced COVID-19 to participants who had not, carefully matching the groups based on age, sex, baseline test date and study location, as well as common risk factors for disease, such as health variables and socioeconomic status.
The team found marked differences in gray matter – which is made up of the cell bodies of neurons that process information in the brain – between those who had been infected with COVID-19 and those who had not. Specifically, the thickness of the gray matter tissue in brain regions known as the frontal and temporal lobes was reduced in the COVID-19 group, differing from the typical patterns seen in the group that hadn’t experienced COVID-19.
In the general population, it is normal to see some change in gray matter volume or thickness over time as people age, but the changes were larger than normal in those who had been infected with COVID-19.
Interestingly, when the researchers separated the individuals who had severe enough illness to require hospitalization, the results were the same as for those who had experienced milder COVID-19. That is, people who had been infected with COVID-19 showed a loss of brain volume even when the disease was not severe enough to require hospitalization.
Finally, researchers also investigated changes in performance on cognitive tasks and found that those who had contracted COVID-19 were slower in processing information, relative to those who had not.
While we have to be careful interpreting these findings as they await formal peer review, the large sample, pre- and post-illness data in the same people and careful matching with people who had not had COVID-19 have made this preliminary work particularly valuable.

1.hour of fox, cnn or msnbc are probably more harmful to the brain than 2.covid infections.
holy , we agree... sort of.
"But if you're vaccinated and get COVID anyhow, the effects are more mild"
Just wait till this thing is (over)...then we'll find out how ed up the one's who got it and the one's who got shot really are.
"But if you're vaccinated and get COVID anyhow, the effects are more mild"
Wow. You may have struck a chord here. Agree.
Maybe, but the ones who didn't get shot will be unemployed.
Yep, the unshot will not be permitted back into "the circle of trust."
Antisocial psychopaths
They should be locked inside the nation inner cities and barbed wire all around.
Think escape from LA/NY
On the nightly news, Gutfeld thoroughly debunked this story.
^ Natural immunity denier
I think he's referring wrongly to herd immunity crowd or people who think they are immune even if they never got the virus.
Yes ,on that we agree.
Sour grapes DS.
Natural immunity exists. But getting to it, especially without vaccination appears to expose you to risk of cognitive loss.
I am referring to the people who think natural immunity is somehow less harmful than the vaccination, because its "natural".
.
Holy
Do you think people with "natural immunity" chose to get COVID? Their concern is that they already have immunity and should not be required to vaccinate.
Thread le "even mild cases"

I suppose having those MASH units mandated like with President Trump is no longer a mandated option.
I suppose having that hospital ship taken out of mothballs and mandated to set sail south out of New York is no longer a mandated option.
Why? Simple:::money was nary problem then. Now, money is a problem.
COVID has outlived it's shelf life.
tee, hee.
The U.S. spends lavishly on healthcare yet can’t answer basic questions about Covid-19. Some of the best research has come from Israel. American public health agencies should be producing data on breakthrough infections, boosters and natural immunity. But the Centers for Disease Control and Prevention has failed to provide the information needed to inform a sound Covid strategy.
Israel began its vaccine rollout with Pfizer in December, only days after the U.S. But Israel kept good data, reported them out frequently and quickly, and used them to track subsequent Covid infections. When the White House announced its plan to recommend a booster shot for all Americans, it cited Israeli data. The World Health Organization and others criticized the plan, calling the evidence insufficient, and in what seemed like a coordinated protest, two top scientists at the Food and Drug Administration abruptly resigned.
The Biden administration recently got the supporting data it needed to justify its booster plan. But not from the CDC. Another Israeli study showed that a booster resulted in a 10-fold reduction in severe Covid illness in people over 60. The results were published mere weeks after the study’s completion, not months later as often happens in the U.S.
“There’s no doubt,” Anthony Fauci said of the findings in a press briefing, “from the dramatic data from the Israeli study that the boosts that are being now done there and contemplated here support very strongly the rationale for such an approach.” The FDA, trying to evaluate the question of boosters, scrambled to obtain the raw data from Israel.
The bigger question is: Why didn’t the CDC produce the research? The agency has 21,000 employees and a $15 billion annual budget. It has data on more than 40 million Americans who have tested positive for Covid and 200 million who have been vaccinated. The data include the vaccine type, dosing schedule and vaccination date. Calculating the rate of U.S. breakthrough infections and subsequent hospitalizations and deaths isn’t the Manhattan Project. It’s Epidemiology 101.
The CDC’s failure to report meaningful data has left policy makers flying blind. In the absence of good data to answer the basic questions Americans have been asking, political opinions have filled the vacuum. Strong data might have prevented much of the polarization over Covid.
Sound data from the CDC has been especially lacking on natural immunity from prior Covid infection. On Aug. 25, Israel published the most powerful and scientifically rigorous study on the subject to date. In a sample of more than 700,000 people, natural immunity was 27 times more effective than vaccinated immunity in preventing symptomatic infections.
Despite this evidence, U.S. public health officials continue to dismiss natural immunity, insisting that those who have recovered from Covid must still get the vaccine. Policy makers and public health leaders, and the media voices that parrot them, are inexplicably sticking to their original hypothesis that natural immunity is fleeting, even as at least 15 studies show it lasts.
Meanwhile, employers fire workers with natural immunity who won’t get vaccinated. Schools disenroll students who won’t comply.
The CDC did put out a study on natural immunity last month, forcefully concluding that vaccinated immunity was 2.3 times better than natural immunity. The CDC used these results to justify telling those with natural immunity to get vaccinated.
But the rate of infection in each group was less than 0.01%, meaning infections were exceedingly rare in the short two-month time period the agency chose to study. This is odd, given there are more than a year of data available. Moreover, despite having data on all 50 states, the CDC only reported data from Kentucky. Was Kentucky the only state that produced the desired result? Why else exclude the same data from the other 49 states?
Some public health officials are afraid to acknowledge natural immunity because they fear some will choose infection over vaccination. But leaders can encourage all Americans who aren’t immune to get vaccinated and be transparent with the data at the same time.
The CDC shouldn’t fish for data to support outdated hypotheses. Heeding the robust Israeli data on natural immunity could help restore the agency’s credibility and even help vaccination efforts.
Israel also contributed a brilliant study on vaccinating children. Researchers found that one dose of the Pfizer vaccine, instead of the normal two, was 100% effective in children ages 12 to 15. Such a finding could have significant implications for achieving broad immunity in adolescents while reducing the risk of heart complications, which have been clustered around the second dose.
These are the studies U.S. public health agencies should be doing but aren’t. By any metric, the CDC has failed in its primary task of preparing the country for a pandemic and telling us how to reduce harm from the novel Covid pathogen.
