(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.

Safeguarding Your American Dream: Discover the Power of America First Healthcare
In today’s economy, healthcare costs remain one of the biggest threats to financial stability and family security. Americans work hard to build a better life, yet rising medical expenses can quickly erode savings, force tough trade-offs, and even push families toward debt or bankruptcy. Medical bills continue to rank as the leading cause of personal bankruptcy in the United States, with millions facing underinsurance or unexpected out-of-pocket burdens that no one plans for. Many turn to government-run marketplace plans under the Affordable Care Act, hoping for relief, only to discover that what appears affordable on paper often delivers higher long-term costs, limited real protection, and coverage that may not align with personal values or family needs.
America First Healthcare stands out as a private insurance agency dedicated to helping conservatives and families secure better coverage and better rates through customized, values-aligned options. By conducting free insurance reviews, the agency uncovers hidden gaps in existing policies and connects clients with private alternatives that emphasize personal responsibility, small-government principles, and genuine affordability—often delivering up to 20% savings while providing stronger protection for the American Dream.
The allure of marketplace plans is easy to understand: open enrollment periods, premium tax credits for many households, and the promise of “comprehensive” benefits mandated by law. Yet recent data reveals a different reality, especially after the expiration of enhanced premium subsidies at the end of 2025. Enrollment for 2026 dropped by more than one million people compared to the prior year, with many shifting to lower-tier bronze plans to keep monthly premiums manageable.
These plans feature significantly higher deductibles—averaging around $7,500 nationally—and greater cost-sharing requirements. Families who once paid modest amounts after subsidies now face average premium increases of $65 or more per month, even as they accept plans that leave them responsible for thousands in upfront costs before meaningful coverage kicks in.
High deductibles create a dangerous barrier to care. Studies show that people in such plans are less likely to seek timely treatment for chronic conditions, attend preventive screenings, or fill necessary prescriptions. A seemingly minor illness or injury can balloon into major expenses when patients delay care until problems worsen. For a family of four, a single hospitalization, cancer diagnosis, or unexpected surgery can easily exceed the deductible, triggering coinsurance and out-of-pocket maximums that still leave substantial bills. One recent analysis noted that some proposed changes could push family deductibles toward $31,000 in future years, further exposing households to financial risk.
Beyond the numbers, marketplace plans often carry structural limitations. Coverage for certain critical services may include waiting periods or narrower networks that restrict access to preferred doctors and specialists. Preventive care is required to be covered without cost-sharing, but everything else—lab work, imaging, specialist visits, or ongoing treatment—typically waits until the deductible is met. This reactive model contrasts sharply with the proactive, holistic approach many families prefer, especially those focused on wellness, early intervention, and maintaining health to enjoy life rather than merely reacting to illness.
Values alignment represents another growing concern. Government-influenced plans operate within a framework shaped by federal mandates and political priorities that may not reflect conservative principles of limited government, personal freedom, and ethical stewardship. Families who want to direct their healthcare dollars toward providers and benefits that honor traditional values sometimes find marketplace options feel misaligned, forcing a compromise between affordability and conviction.
Private alternatives, by contrast, offer year-round flexibility without the restrictions of open enrollment windows. Independent agents can shop across a wider range of carriers to design plans tailored to specific family needs—whether that means lower deductibles for frequent medical users, broader provider networks, or add-ons that support wellness and preventive services from day one. Clients frequently report more stable premiums that do not automatically escalate each year, along with genuine cost savings once the full picture of deductibles, copays, and coverage depth is considered.
Take the experience of real families who made the switch. Amanda C. shared that her new plan felt “way better” than what she had through the marketplace. Johnny Y. noted his previous coverage kept increasing annually until he found a more stable private option. Sofia S. expressed delight with her plan and began recommending it to others. These stories echo a common theme: when families move beyond one-size-fits-all government marketplaces, they often discover customized protection that better safeguards both health and finances.
Founder Jordan Sarmiento’s own journey underscores the stakes. In 2021, a six-day hospitalization generated a $95,000 bill. Under a well-structured private “Conservative Care Coverage” plan, his out-of-pocket responsibility would have been just $500. That stark difference illustrates how thoughtful planning and private options can prevent a medical event from becoming a financial catastrophe.
Practical steps exist for anyone questioning their current coverage. Start with a no-obligation review of your existing policy to identify gaps—high deductibles, limited critical-care benefits, or escalating premiums. Compare total projected costs (premiums plus potential out-of-pocket expenses) rather than monthly premiums alone. Consider family health history, anticipated needs, and lifestyle priorities. Private agencies can present side-by-side options that include stronger wellness incentives, broader access, and plans built on shared values of self-reliance and freedom.
In an era when healthcare inflation continues to outpace general cost-of-living increases, relying solely on marketplace solutions carries growing risk. Families who proactively explore private alternatives frequently achieve meaningful savings while gaining peace of mind that their coverage truly works when needed most.
America First Healthcare makes this exploration straightforward through its free review process. Families and individuals receive personalized guidance to close coverage holes, reduce unnecessary expenses, and secure plans that align with conservative principles—protecting wallets, health, and the American Dream without government overreach. Many who complete a review discover they can enjoy better benefits for less, often saving up to 20% while gaining the customization and stability that marketplace plans struggle to deliver.
Ultimately, protecting your family’s future requires looking beyond the marketing of “affordable” government options. By understanding the long-term costs hidden in high deductibles, shifting coverage tiers, and values mismatches, Americans can make empowered choices. Private, values-driven insurance offers a smarter path—one that rewards diligence, supports wellness, and delivers real security. For those ready to move beyond the limitations of traditional marketplace plans, a simple review can reveal options designed to serve families, not bureaucracies. The American Dream thrives when individuals and families retain control over their healthcare decisions, and thoughtful private coverage plays a vital role in making that possible.
