Even a mild case of COVID can shrink your brain the same as aging 10 years, study shows

Even a mild case of COVID can cause a loss of brain matter equivalent to a decade of aging, according to an early version of a new study published in Nature on Monday, leading to "larger cognitive decline" than people who have never suffered COVID.

The study provides additional evidence of the effects of COVID throughout the body, some of which may have permanent repercussions on a patient’s health.

The study of 785 volunteers, aged 51 to 81, was conducted in conjunction with U.K. Biobank—an initiative to catalog the health information of half a million U.K. residents. Researchers compared two MRI scans of each subjects brain, taken 38 months apart, with the first scan conducted before the pandemic began. In the intervening period, 401 of the volunteers had tested positive for COVID, providing a test and control group for the effects of the coronavirus on the brain.

Under normal circumstances, people lose about 0.2 to 0.3% of their brain matter each year through aging. Yet the study found that COVID patients experienced an additional loss of anywhere between 0.2 to 2% of their brain size in the three years between MRI scans. At worst, that an equivalent loss to your brain shrinking over 10 years.

Only 15 of the volunteers who tested positive for COVID needed to be hospitalized due to the virus, meaning that even mild cases led to noticeable loss of brain matter.

Researchers also found damage in the areas of the brain responsible for smell, which may help to explain one of the most commonly-reported COVID symptoms: the loss of smell and taste.

“This is pretty convincing evidence that something changes in the brains of this overall group of people with COVID”, Dr. Serena Spudich of the Yale School of Medicine, who was not involved in the study, told the New York Times.

Despite being primarily known as a respiratory illness, COVID attacks several parts of the body besides the lungs. A study late last year found that the coronavirus could attack fat cells directly, perhaps explaining why overweight and obese patients have been more susceptible to severe COVID.

COVID patients can suffer from a wide range of chronic conditions months after testing positive, including depression, hair loss and fatigue. COVID has also been correlated with higher rates of cardiovascular disease and heart attacks. Even mild cases appear to trigger instances of "long COVID”, contributing to a public health phenomenon that threatens to drag on economies post-COVID.

Still, scientists cautioned against linking a reduction in brain matter to cognitive decline. Spudich said to Bloomberg, “We are fortunate to have extremely resilient brains that can function with many potential insults without experiencing any impairment."

More research is required to determine whether the shrinking effects of COVID on human brains is permanent, too. As neuroscientist Gwenaëlle Douaud, one of the authors of the study, said, “The brain is ‘plastic’ and can heal itself."

I've often enough heard that excuse... usually in the form of "you guys don't know what you;re talking about" re shorts in the gold and silver market... because, they say, the "shorts" are actually the producers hedging production... so, "nothing to see here"...

But, market reality turns out to be... it doesn't matter who the trader is... and, only more true if they can't meet a margin call... as producers are no more clairvoyant and no less subject to error than other traders in the game... and, may be less so... given "other things" to focus on than exogenous market risks... while lacking to concern others may have, given the apparent surety in the "metal in the ground" argument...

Miners focused on mining... also tend to be less aware of exogenous risks than investors... who are not going to work in the mine each day... but are mulling the geopolitical variables as the breezes shift... Hence, First Majestic realizes geopolitical risks that I do not... because... I can move my position in a few minutes... and they have, thus far, proven unable to move their mines...

The error in logic is not different than others of the same ilk in the relative value in "who you know" versus "what you know". Corruption naturally encourages fostering dependency on who you know... while traders livelihood depends on awareness that a tendency to error in logical fallacies is a human trait that has not been overcome... so that willingness to be patient and go against the herd, expecting reality to win out in the end over corruption... is an essential.

I do not dismiss the result of one traders error as "a one off"... rather than an indication of "more like that out there"... being masked by the tendency...

I suspect that traders in nickel experiencing margin calls... will have linkages to other trades in other metals...
and, whether that is true or not... traders, including producers, who are short, say, silver... cannot be blind to the fact that... short positions in a market spiking higher... can be company killers... Silver experienced some of that in Feb of 2020 into March of 2021... as production was unable to backstop the push... Today, it may not be Covid imposing the problems... but the nature of the risk now is "faster"...



The dreaded C word is being avoided... but contagion is clearly a possibility...

Keep your head up and you vision unclouded... by others "expectations" re normalcy... more when that inducement to expect normalcy depends on function in human cooperation... at a point where it is failure in human cooperation that is driving dislocations in balances between expectations and realities...
