(The Epoch Times)—A new study found that COVID-19 infection can cause cognitive deficits that persist for over a year and lower IQ scores in severe cases. Those with persistent symptoms that resolved had small cognitive deficits similar to those with a shorter illness duration.
In a large-scale observational study published on Feb. 29 in the New England Journal of Medicine (NEJM), researchers invited 800,000 people with varying levels of COVID-19 exposure and duration to take an online cognitive assessment and follow-up survey. Cognitive difficulties have been implicated in numerous syndromes following COVID-19, including long COVID, suggesting infection may have lasting effects on the mental processes of the brain.
The study’s authors hypothesized there would be measurable cognitive deficits after COVID-19 that would scale with the severity and duration of the illness. They also speculated that objective impairments in executive and memory function, especially poor memory and brain fog, would be observable in those with persistent symptoms.
Using an assessment tool for cognitive function, researchers estimated global cognitive scores among participants with a history of previous SARS-CoV-2 infection who had symptoms for at least 12 weeks—whether resolved or not—and among a control group of uninfected participants. While cognitive and memory deficits were small for people with mild infection who recovered from COVID-19 quickly, impairments were more pronounced in those with severe disease.
Greater Impairment With More Severe Disease
Of 112,964 participants who completed the survey, those who recovered from COVID-19 with symptoms that resolved in less than four weeks or by 12 weeks post-infection had similar small deficits in global cognition compared with those who had never had COVID-19.
Participants who had mild COVID-19 with resolved symptoms experienced a 3-point drop in IQ compared to uninfected participants. Those with unresolved persistent symptoms had a 6-point loss in IQ, and those with COVID-19 admitted to the intensive care unit experienced a 9-point loss in IQ. Reinfection with SARS-CoV-2 caused an additional loss in IQ of nearly 2 points compared to those who were not reinfected. An IQ, or intelligence quotient, is a number used to represent the relative intelligence of an individual.
According to the study, memory, reasoning, and executive function tasks were the strongest indicators of impaired cognitive function, and these scores correlated with brain fog symptoms reported by participants. More significant deficits were seen in those with unresolved persistent symptoms and those infected with earlier variants of the SARS-CoV-2 virus compared with those who never had COVID-19. Additionally, study participants who were hospitalized had greater deficits in cognitive function compared to those who were not hospitalized.
“By using an innovative cognitive test which has also been completed by people who did not have COVID-19, this important and well-conducted study provides the first accurate quantification of the scale of cognitive deficits in people who had COVID-19,” Maxime Taquet, a fellow in psychiatry at the National Institute for Health and Care Research at the University of Oxford, said in a statement.
Mr. Taquet said researchers found a small but obvious association between COVID-19 and cognition that was more pronounced at extremes.
“The risk of having more severe cognitive problems was almost twice as high in those who had COVID-19 compared to those who did not, and three times as high in those who were hospitalized with COVID-19,” he noted.
In an editorial published Feb. 29 in the NEJM, Drs. Ziyad Al-Aly and Clifford Rosen said the study’s results are concerning and have broad implications that require further evaluation to determine the functional impact of a 3-point loss in IQ and why one group of participants was more severely affected than another.
“Whether these cognitive deficits persist or resolve along with predictors and trajectory of recovery should be investigated. Will Covid-19-associated cognitive deficits confer a predisposition to a higher risk of Alzheimer’s disease or other forms of dementia later in life? The effects on educational attainment, work performance, accidental injury, and other activities that require intact cognitive abilities should also be evaluated,” they wrote.
Study Implications for People With Long COVID
The study’s participants were part of a larger community sample of nearly 3 million people in the Real-time Assessment of Community Transmission (REACT) study assessing SARS-CoV-2 transmission in England. Although the researchers did not say whether participants in the study had long COVID, people with long COVID frequently report persistent cognitive impairment.
There is no accepted universal definition for the condition, but the Centers for Disease Control and Prevention (CDC) broadly defines long COVID as “signs, symptoms, and conditions that continue to develop after acute COVID-19 infection” that can last for “weeks, months, or years.” The term “long COVID” also includes post-acute sequelae of SARS-CoV-2 infection, long-haul COVID, and post-acute COVID-19.
Nearly 7 percent of U.S. adults surveyed by the CDC in 2022 said they’ve experienced long COVID. Although U.S. regulatory agencies claim vaccinating against COVID-19 can reduce the risk of developing long COVID and the current paper suggests vaccination with two or more doses may provide a slight cognitive advantage, a recent paper published in the Journal of Clinical Medicine did not find a significant link between the presence of comorbidities or infection severity and the emergence of long COVID symptoms.
The NEJM study has several limitations, including reliance on subjective reporting to identify individuals with ongoing symptoms and self-selection bias. People with long COVID may have enrolled in the study, but those with more severe impairments may not have been able to participate in the survey. Additionally, certain groups were overrepresented in the study compared with the base population. Baseline cognitive data before SARS-CoV-2 infection was also unavailable, so researchers could not assess cognitive change or infer causality.
Five Things New “Preppers” Forget When Getting Ready for Bad Times Ahead
The preparedness community is growing faster than it has in decades. Even during peak times such as Y2K, the economic downturn of 2008, and Covid, the vast majority of Americans made sure they had plenty of toilet paper but didn’t really stockpile anything else.
Things have changed. There’s a growing anxiety in this presidential election year that has prompted more Americans to get prepared for crazy events in the future. Some of it is being driven by fearmongers, but there are valid concerns with the economy, food supply, pharmaceuticals, the energy grid, and mass rioting that have pushed average Americans into “prepper” mode.
There are degrees of preparedness. One does not have to be a full-blown “doomsday prepper” living off-grid in a secure Montana bunker in order to be ahead of the curve. In many ways, preparedness isn’t about being able to perfectly handle every conceivable situation. It’s about being less dependent on government for as long as possible. Those who have proper “preps” will not be waiting for FEMA to distribute emergency supplies to the desperate masses.
Below are five things people new to preparedness (and sometimes even those with experience) often forget as they get ready. All five are common sense notions that do not rely on doomsday in order to be useful. It may be nice to own a tank during the apocalypse but there’s not much you can do with it until things get really crazy. The recommendations below can have places in the lives of average Americans whether doomsday comes or not.

Secured Wealth
Whether in the bank or held in a retirement account, most Americans feel that their life’s savings is relatively secure. At least they did until the last couple of years when de-banking, geopolitical turmoil, and the threat of Central Bank Digital Currencies reared their ugly heads.
It behooves Americans to diversify their holdings. If there’s a triggering event or series of events that cripple the financial systems or devalue the U.S. Dollar, wealth can evaporate quickly. To hedge against potential turmoil, many Americans are looking in two directions: Crypto and physical precious metals.
There are huge advantages to cryptocurrencies, but there are also inherent risks because “virtual” money can become challenging to spend. Add in the push by central banks and governments to regulate or even replace cryptocurrencies with their own versions they control and the risks amplify. There’s nothing wrong with cryptocurrencies today but things can change rapidly.
As for physical precious metals, many Americans pay cash to keep plenty on hand in their safe. Rolling over or transferring retirement accounts into self-directed IRAs is also a popular option, but there are caveats. It can often take weeks or even months to get the gold and silver shipped if the owner chooses to close their account. This is why Genesis Gold Group stands out. Their relationship with the depositories allows for rapid closure and shipping, often in less than 10 days from the time the account holder makes their move. This can come in handy if things appear to be heading south.
Lots of Potable Water
One of the biggest shocks that hit new preppers is understanding how much potable water they need in order to survive. Experts claim one gallon of water per person per day is necessary. Even the most conservative estimates put it at over half-a-gallon. That means that for a family of four, they’ll need around 120 gallons of water to survive for a month if the taps turn off and the stores empty out.
Being near a fresh water source, whether it’s a river, lake, or well, is a best practice among experienced preppers. It’s necessary to have a water filter as well, even if the taps are still working. Many refuse to drink tap water even when there is no emergency. Berkey was our previous favorite but they’re under attack from regulators so the Alexapure systems are solid replacements.
For those in the city or away from fresh water sources, storage is the best option. This can be challenging because proper water storage containers take up a lot of room and are difficult to move if the need arises. For “bug in” situations, having a larger container that stores hundreds or even thousands of gallons is better than stacking 1-5 gallon containers. Unfortunately, they won’t be easily transportable and they can cost a lot to install.
Water is critical. If chaos erupts and water infrastructure is compromised, having a large backup supply can be lifesaving.
Pharmaceuticals and Medical Supplies
There are multiple threats specific to the medical supply chain. With Chinese and Indian imports accounting for over 90% of pharmaceutical ingredients in the United States, deteriorating relations could make it impossible to get the medicines and antibiotics many of us need.
Stocking up many prescription medications can be hard. Doctors generally do not like to prescribe large batches of drugs even if they are shelf-stable for extended periods of time. It is a best practice to ask your doctor if they can prescribe a larger amount. Today, some are sympathetic to concerns about pharmacies running out or becoming inaccessible. Tell them your concerns. It’s worth a shot. The worst they can do is say no.
If your doctor is unwilling to help you stock up on medicines, then Jase Medical is a good alternative. Through telehealth, they can prescribe daily meds or antibiotics that are shipped to your door. As proponents of medical freedom, they empathize with those who want to have enough medical supplies on hand in case things go wrong.
Energy Sources
The vast majority of Americans are locked into the grid. This has proven to be a massive liability when the grid goes down. Unfortunately, there are no inexpensive remedies.
Those living off-grid had to either spend a lot of money or effort (or both) to get their alternative energy sources like solar set up. For those who do not want to go so far, it’s still a best practice to have backup power sources. Diesel generators and portable solar panels are the two most popular, and while they’re not inexpensive they are not out of reach of most Americans who are concerned about being without power for extended periods of time.
Natural gas is another necessity for many, but that’s far more challenging to replace. Having alternatives for heating and cooking that can be powered if gas and electric grids go down is important. Have a backup for items that require power such as manual can openers. If you’re stuck eating canned foods for a while and all you have is an electric opener, you’ll have problems.
Don’t Forget the Protein
When most think about “prepping,” they think about their food supply. More Americans are turning to gardening and homesteading as ways to produce their own food. Others are working with local farmers and ranchers to purchase directly from the sources. This is a good idea whether doomsday comes or not, but it’s particularly important if the food supply chain is broken.
Most grocery stores have about one to two weeks worth of food, as do most American households. Grocers rely heavily on truckers to receive their ongoing shipments. In a crisis, the current process can fail. It behooves Americans for multiple reasons to localize their food purchases as much as possible.
Long-term storage is another popular option. Canned foods, MREs, and freeze dried meals are selling out quickly even as prices rise. But one component that is conspicuously absent in shelf-stable food is high-quality protein. Most survival food companies offer low quality “protein buckets” or cans of meat, but they are often barely edible.
Prepper All-Naturals offers premium cuts of steak that have been cooked sous vide and freeze dried to give them a 25-year shelf life. They offer Ribeye, NY Strip, and Tenderloin among others.
Having buckets of beans and rice is a good start, but keeping a solid supply of high-quality protein isn’t just healthier. It can help a family maintain normalcy through crises.
Prepare Without Fear
With all the challenges we face as Americans today, it can be emotionally draining. Citizens are scared and there’s nothing irrational about their concerns. Being prepared and making lifestyle changes to secure necessities can go a long way toward overcoming the fears that plague us. We should hope and pray for the best but prepare for the worst. And if the worst does come, then knowing we did what we could to be ready for it will help us face those challenges with confidence.
