Can Covid -19 damage the brain?
Research from the Alzheimer’s Association annual conference shows that Covid -19 can lead to cognitive issues—but many questions still remain.
It’s no secret that Covid-19 infections can have an effect on the neurological system. From the early days of the pandemic, reports of brain fog, memory issues and confusion showed that the virus impacts much more than the lungs. But what do we really know about how Covid-19 can damage the brain? Research presented at the Alzheimer’s Association International Conference on July 29 sheds some light on how Covid-19 impacts brain function.
Severe Covid-19 Damages The Brain—But Brain Cells Can RecoverResearchers have already shown that a Covid-19 infection can lead to brain cell damage during the acute phase of the illness, particularly in patients who are sick enough to end up in the ICU. But according to new research, these brain cells
seem to recoverafter three to six months. Nelly Kanberg, a researcher at the Institute of Biomedicine at the University of Gothenburg in Sweden, measured biomarkers in the brain that showed while brain cells in some patients became damaged during severe Covid-19, these biomarkers go back down to “normal” levels a few months after infection. This shows that the brain can recover and heal—though some patients will still suffer from long-term cognitive issues. One persistent mystery, Kanberg says, is that we don’t yet know exactly how Covid damages the brain. It “may be a result of a combination of factors,” she says, including an inflammatory response, injuries to blood vessels and issues with clotting. headtopics.com
Older Adults Are More Likely To Have Neurological Issues After Covid-19 InfectionAnother study conducted in Argentina found that adults over the age of 60 were likely to have issues with cognitive function, such as memory loss and confusion, after a Covid-19 infection. Gabriel A. de Erausquin, a neurology researcher at the University of Texas Health Science Center at San Antonio, says his study showed that among people age 60 and over, close to 60% of those exposed to Covid-19 have trouble with memory and cognition. This represents an almost tenfold increase in neurological issues in this population, he says. Interestingly, adults who have lost their sense of smell during a Covid-19 infection are more likely to have brain issues. This may be a clue to the relationship between Covid-19 and degenerative brain diseases like Alzheimer’s disease, which can also involve loss of smell. “The [brain] regions affected by both overlap,” De Erausquin says. If these seniors don’t recover fully, “then we are facing potentially a very large increase in Alzheimer’s cases,” he says. De Erausquin plans to follow the 234-person study group for the next five years to see if the cognitive issues in older adults improve like those in Kanberg’s study.
Younger Covid Patients Can Have Brain Problems, Too A third study, conducted by George D. Vavougios, a neurology research associate at the Athens Naval Hospital in Greece, found that it’s not just elderly people who suffer cognitive issues after a Covid infection. In his study, people as young as 40 showed cognitive decline, including short-term memory issues and other forms of impairment, after infection with the virus. The people who were most likely to have brain issues were those who had post-Covid fatigue and poor lung function even after the initial infection was gone. Vavougios says his findings show that doctors should screen Covid-19 patients, even young patients who didn’t have severe disease, for symptoms of cognitive decline.
There Are Still A Lot Of UnknownsDespite all this new evidence linking Covid-19 to cognitive issues, including memory problems that are similar to Alzheimer’s disease, we still don’t know exactly how Covid infections and cognitive issues are linked. Heather Snyder, vice president of Medical & Scientific Relations at the Alzheimer’s Association, says that researchers around the world will continue to investigate exactly how Covid can impact the brain. In the meantime, patients shouldn’t stress out too much. “Having Covid-19 does not mean that you’re going to develop Alzheimer’s,” she says, “We don’t know what that connection is.” While the two diseases do seem to show some similarities, getting Covid-19 does not automatically mean that you will have issues with brain function. “We don’t really know why one person does and one person doesn’t,” she says.
That being said, the best way to prevent brain damage from Covid-19 is to not get sick at all—yet another reason to encourage people to get vaccinated against the disease. Read more: Forbes »

Vast majority of ICU patients with COVID-19 are unvaccinated, ABC News survey findsDozens of hospitals surveyed by ABC News across the country report that very few fully vaccinated people are ending up in the ICU with COVID-19. Of course. What would you expect Don't care Come on now. Are you telling the truth?
Florida's unexpected COVID-19 Delta surge could be prolonged: Infection expertFlorida health officials said that while they expected an uptick in coronavirus metrics over the summer, none predicted the Delta surge to be as significant as it has been across the state. Changes in the death rate is all that matters. All else is political propaganda. Delta was significant in india and uk and now in decline. Read article in ny times about it today. Cases arent deaths. Why get vaccine if you can still catch/spread it and have to follow same vaccine mandates as un vaccinated? Im never getting it.
House Republicans stage protest in Capitol over new COVID-19 mask rulesA group of House Republicans marched to the Senate floor Thursday to protest the new House mask mandate imposed by the Capitol's attending physician. Americans always complaining about things. Here in Asia, to innovate and to adopt temporarily, we make face masks as a fashion statement. Keeping safe in style! Hahahaha. Stupid stuff I’m tired of this stupid stuff it insults my intelligence Making fools of themselves and endangering lives with their ignorance smh
