How Covid Quietly Rewires the Brain
Researchers keep discovering more about the long-term neurological effects of SARS-CoV-2.


AI Summary:
The article reports that researchers are uncovering long-term neurological effects of SARS-CoV-2, suggesting Covid-19 can disrupt and potentially damage the brain, not just the lungs.

Early in the pandemic, Avindra Nath of the National Institute of Neurological Disorders and Stroke investigated unexplained deaths in New York in which victims stopped breathing without lung or heart damage. High-resolution imaging and microscopic examination revealed loss of neurons in brain stem regions that control breathing. Later, recovering patients described episodes in which breathing no longer felt automatic, resembling Ondine’s curse.

As the pandemic progressed, clinics filled with patients whose initial respiratory symptoms had resolved but who experienced persistent fatigue, cognitive slowing, malaise and other symptoms. Many cases overlapped with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS), and later studies found a substantial share of long-Covid patients met ME/CFS diagnostic criteria. Damage in the brain stem and surrounding tissue may interfere with thinking, mood and regulation of heart rate, digestion and blood pressure.

Long Covid has risen rapidly in diagnoses and become economically disruptive. A December study estimated up to 400 million people worldwide are living with long-term consequences of infection, and a November analysis put the annual global economic toll at $1 trillion.

Research increasingly links Covid to structural and cognitive changes in the brain. UK Biobank scans showed subtle loss in regions involved in planning and memory, even after mild infections, along with small declines in cognitive scores in community studies. Although risks appear lower after vaccination and milder infections, they have not disappeared.

In a UK human challenge study, healthy young adults infected with the original strain performed slightly worse a year later on memory and decision-making tests—about a six-point IQ difference—despite mild illness and no reported lasting problems. Observational research and large datasets have found higher risks of cognitive impairment and, in older adults, dementia-level decline months or years after infection.

Older adults and those severely ill appear most affected. Blood tests have revealed proteins linked to Alzheimer’s disease, including phosphorylated tau, particularly in patients with persistent neurological symptoms. A study from NYU Langone Health found enlargement and impaired blood flow in a brain structure involved in immune regulation and waste clearance, along with Alzheimer’s-linked blood markers.

While some researchers caution that biomarkers do not guarantee dementia, Nath argues Covid can accelerate neurodegenerative processes already underway in aging populations. Korean researchers reported structural and biochemical changes about a year after mostly mild infections in patients with lingering cognitive problems, including thinner brain regions tied to attention and memory, iron buildup, enlargement of a structure involved in immune regulation and waste clearance, and blood markers of ongoing brain stress and injury. These findings were replicated in a separate group.

The emerging picture is of subtle but widespread cognitive effects that may erode independence and productivity over time. Nath is leading a clinical trial at the NIH treating long Covid as an immune-driven neurological condition, testing whether immunomodulating therapies can reduce lingering inflammation and restore function. The study is expected to conclude later this year.
 
"How Covid Quietly Rewires the Brain"
Bloomberg said:
Before long, clinics were filling with patients who said their fevers and coughs had resolved but they were now experiencing crushing fatigue, cognitive slowing, malaise and swollen lymph nodes. This cluster of symptoms overlapped with myalgic encephalomyelitis, or chronic fatigue syndrome, a poorly understood illness that has long followed viral infections in some patients. Often referred to as ME/CFS, it can be a lifelong, debilitating condition that leaves sufferers unable to work or even to manage basic daily activities. Because ME/CFS itself has long been contested and underdiagnosed, the resemblance also meant many of the recovering Covid patients struggled to be taken seriously or to find effective treatment.

The overlap in symptoms, Nath says, is “not all that surprising because a lot of viral infections have been associated with this syndrome.” Indeed, some later studies of what came to be known as long Covid showed that a substantial share of patients met the diagnostic criteria for ME/CFS.
Bloomberg said:
Almost five years later, long Covid has had one of the fastest rises in diagnoses and become one of the most economically disruptive chronic conditions in modern medicine. A study published in December estimated that as many as 400 million people worldwide are living with long-term consequences of a SARS-CoV-2 infection. Another analysis, released in November, put the annual economic toll of long Covid at $1 trillion, close to 1% of global gross domestic product.

That scale in turn raises a troubling question: whether Covid is not only leaving millions chronically unwell but also accelerating the slow neurological processes that end in dementia—a pattern that has long been observed after some viral infections.

AI Summary:
What We Forget About Covid Will Shape the Next Pandemic

As the Covid-19 pandemic becomes more distant, people increasingly remember it as less frightening and chaotic than it was at the time. Research shows that memory is reconstructive: people reinterpret past events according to current beliefs and narratives. As a result, some now claim hospitals were never truly overwhelmed or frame measures such as vaccine mandates as coercive rather than emergency responses, despite mortality data and official records showing severe impacts.

Misremembering the pandemic has consequences. Around 400 million people are estimated to live with long Covid, and many survivors of severe illness face long-term heart, lung, or cognitive problems. Disruptions to healthcare during the pandemic also caused lasting damage, while life expectancy fell in several high-income countries. If the pandemic is remembered as exaggerated, these burdens may be ignored, weakening support for disability programs, research funding, and long-term care.

How societies remember Covid will also influence preparedness for future crises. If past responses are seen as overreactions, governments may invest less in surveillance, research, and medical countermeasures, and leaders may hesitate to act early during the next outbreak. Early decisions in public health are often made under uncertainty, with limited data and rapidly evolving situations, but hindsight can make them appear unnecessary or mistaken.

Historical examples show that collective memory often simplifies crises. Later narratives about the 1630 plague in Milan and the early AIDS crisis portrayed the dangers as obvious and early hesitation as failure, even though uncertainty and disagreement were widespread at the time. Societies tend to revise their past in ways that restore a sense of control and reduce discomfort.

Accurate memory requires remembering the conditions in which decisions were made: limited information, fast-spreading disease, and credible risks of health-system collapse. The next pandemic will likely begin with small, uncertain signals and debate over how serious it is. In that moment, collective memory of Covid will shape what actions seem reasonable.

If Covid is mainly remembered for excessive restrictions or exaggerated danger, early warnings in the next crisis may be ignored and vaccination uptake may decline. Preparedness depends on maintaining tools and knowledge developed during the pandemic—such as adaptable vaccine platforms, rapid home diagnostics, wastewater surveillance, and improved understanding of indoor air transmission.

Finally, memory also affects how societies treat those still suffering from the pandemic’s consequences, including people with long Covid, survivors of critical illness, and children affected by educational disruptions.

The biology of future viruses is unpredictable, but how societies respond will depend heavily on how they remember Covid.
