Inside the Mind: How Long COVID Affects Brain Function
The study highlights a significant link between brainstem damage caused by COVID-19 and the persistence of physical and mental health symptoms in Long COVID patients.
United States – Strokes in the brainstem may be attributed to the physical and psychological manifestations of Long COVID, according to a new study.
Thirty Long COVID patients had MRI scans, which showed for the first time that damage was done to a part of the brainstem that controls symptoms like breathlessness, fatigue, and anxiety, as reported in the Brain journal on Oct 7, as reported by HealthDay.
Understanding the Role of the Brainstem
“The brainstem is the critical junction box between our conscious selves and what is happening in our bodies,” said co-lead researcher James Rowe, a senior research fellow with the University of Cambridge Department of Clinical Neurosciences. “The ability to see and understand how the brainstem changes in response to COVID-19 will help explain and treat the long-term effects more effectively.”
Autopsies of individuals who succumbed to severe COVID-19 in its early phase revealed alterations in the brainstem, researchers noted in background information.
Inflammatory Damage from COVID-19
“People who were very sick early in the pandemic showed long-lasting brain changes, likely caused by an immune response to the virus. But measuring that immune response is difficult in living people,” Rowe said. “Normal hospital-type MRI scanners can’t see inside the brain with the kind of chemical and physical detail we need.”
Thus, the research team used stronger MRI machines called 7-Tesla scanners and established that COVID infection resulted in inflammation damage in several areas of the brainstem.
These abnormalities arose several weeks after admission to the hospital, usually in areas of the brain governing respiratory functions, the scientists clarified.
Connection Between Physical and Mental Health
“The fact that we see abnormalities in the parts of the brain associated with breathing strongly suggests that long-lasting symptoms are an effect of inflammation in the brainstem following COVID-19 infection,” said co-lead researcher Dr. Catarina Rua, a postdoctoral researcher with the University of Cambridge. “These effects are over and above the effects of age and gender and are more pronounced in those with severe COVID-19.”
The brain scans also showed damage in areas related to fatigue and anxiety, researchers said, as reported by HealthDay.
“Mental health is intimately connected to brain health, and patients with the most marked immune response also showed higher levels of depression and anxiety,” Rowe said in a Cambridge news release. “Changes in the brainstem caused by COVID-19 infection could also lead to poor mental health outcomes because of the tight connection between physical and mental health.”

New Discovery: 5 Blood Proteins Could Foreshadow Liver Illness Over a Decade Early
A study pinpoints five elusive blood proteins that can flag severe liver illness up to 16 years before symptoms strike, offering a chance of prolonged health.

Forecasting ailments long before their grip tightens could shift the medical realm from reactive to preventative. A group of researchers has spotlighted five subtle yet potent blood proteins capable of forewarning an individual’s odds of enduring an advanced liver malady—well over a decade before it manifests. These transformative revelations, slated for unveiling at Digestive Disease Week (DDW) 2025, unlock avenues for swifter detection, swifter actions, and, perhaps, superior outcomes.
Silent Surge of MASLD
This research zeroes in on metabolic dysfunction-associated steatotic liver disease (MASLD), a silent epidemic now reigning as the foremost liver disease worldwide. The frequency of MASLD continues to swell, dragging along a fatality risk that towers nearly twofold over those untouched by it.
Whispers from Within: The Biomarker Breakthrough
“Picture having foresight into MASLD’s threat long before it stirs,” shared Dr. Shiyi Yu, a resident in gastroenterology at Guangdong Provincial People’s Hospital, China. “Most only recognize liver peril after it clenches tight. There’s a dire craving for reliable biomarkers and forecasting blueprints. Our endeavor uncovers plasma proteins as harbingers of hope,” according to SciTechDaily.com.
Scientists Discover 5 Proteins That Can Predict Liver Disease Up to 16 Years Before Symptoms Appearhttps://t.co/CEanUqHoGs

Drilling into over 50,000 blood specimens from the UK Biobank and tracing participants for 16+ years, researchers scrutinized over 2,700 distinct proteins. From this biological sea, five proteins surfaced as early harbingers: CDHR2, FUOM, KRT18, ACY1, and GGT1—biochemical whispers of liver calamity to come.
Numbers That Speak Volumes
This protein ensemble demonstrated a startling foresight: an 83.8 percent predictive edge five years out, tapering only slightly to 75.6 percent at the 16-year mark. When meshed with day-to-day markers like body mass and physical movement, the model’s accuracy surged—hitting 90.4 percent at five years and 82.2 percent across sixteen.
Dr. Yu added, “Our model echoed its precision in an entirely different group in China, underscoring its resilience and broad applicability,” as per SciTechDaily.com.
Still Waters Run Deep
Despite its brilliance, the study remains observational—it detects links, not causes. But with pathways still being explored, this discovery ushers in a fresh frontier, where blood murmurs truths long before pain speaks.

Beloved Spice Could Secretly Sabotage Your Medications, Study Warns – Are You at Risk?
A recent study reveals cinnamon’s core compound could hasten drug metabolism, undermining the efficacy of prescription medications. Discover the hidden risks behind this cherished spice.

A recent scientific study has flagged an unsuspecting pantry staple as a potential troublemaker in your body’s drug-handling mechanics — cinnamon.
Beneath its warm aroma and nostalgic taste, researchers at the University of Mississippi have identified cinnamaldehyde — the chief aromatic in cinnamon — as a molecular agitator. This compound can awaken certain cellular gateways (receptors) that speed up how your body clears specific medications, possibly rendering them less potent than intended.
While a sprinkle atop your cappuccino likely won’t stir trouble, the study casts a cautionary spotlight on high-dosage consumption, especially via supplements, according to the New York Post.
Dosing Dangers Lurking in Plain Sight
“Health hazards may arise if hefty volumes of supplements are ingested without a clinician’s awareness or guidance,” stated Shabana Khan, principal researcher on the project.
Overindulgence could push your system to purge medications prematurely, sabotaging their intended purpose.
Notably, the study points out that cinnamon oil — a frequent fixture in flavor additives and personal care products — shows minimal risk in this context. It’s the bark, particularly from Cassia cinnamon, that raises eyebrows.

Cassia vs. Ceylon: A Spicy Identity Crisis
Cassia cinnamon — a low-cost variety imported from southern China — harbors coumarin, a naturally occurring compound with blood-thinning traits. This could spell danger for individuals already navigating anticoagulant therapies.
“Ceylon cinnamon, often dubbed ‘true cinnamon’ and sourced from Sri Lanka, bears far less coumarin, making it a safer bet,” explained Amar Chittiboyina, a co-author and deputy director at the National Center for Natural Products Research.
Supermarket shelves mostly carry Cassia, cloaked in generic packaging as simple “ground cinnamon.”
The Fine Line Between Healing and Harm
Historically, cinnamon has earned praise for its alleged therapeutic potential — from leveling blood sugar to easing inflammation. But this fresh wave of evidence underscores the shadow side of overuse, as per the NY Post.
People living with long-term health conditions — diabetes, hypertension, autoimmune disorders, or psychological ailments — should tread especially carefully.
“Our top-line advice: always consult a health care professional before pairing any supplements with prescribed treatments,” Khan emphasized. “Supplements aren’t cures. They’re not crafted to heal, treat, or offset diseases.”
Tread Gently With Nature’s Power
Cinnamon might still spice up your life in meaningful ways — but when taken in heavy doses, it may quietly unravel the work of vital medications.
As with any potent natural remedy, the key lies in mindful use — not blind enthusiasm.

Your Daily Diet Might Be Deadlier Than You Think — Find Out Why
A profound study reveals the alarming link between ultra-processed foods and premature deaths across multiple nations, urging critical reevaluation of modern eating habits.

In a modern world saturated with quick-fix edibles, ultra-processed foods (UPFs) — brimming with excessive sugars, salts, and detrimental fats — now constitute a staggering 70 percent of the American food landscape.
A fresh dissection of global datasets from the United States and seven other nations sought to gauge how many untimely, avoidable fatalities stem from the habitual ingestion of items like processed meats, packaged sweets, sugary beverages, and artificially sweetened breakfast cereals.
Carlos Augusto Monteiro, emeritus authority in nutrition and public health at Brazil’s University of São Paulo, shared with CNN, “We scrutinized the peril of dying prematurely — between the ages of 30 and 69 — directly linked to escalating consumption of UPFs,” according to the New York Post.
Monteiro’s research unveiled a stark reality: for every 10% augmentation in calorie intake from UPFs, the hazard of an early grave intensifies by nearly 3 percent. These findings surfaced in the latest edition of the American Journal of Preventive Medicine.
Prior explorations have already tied UPFs to over 32 adverse health predicaments — encompassing heightened dangers of cardiac maladies, oncological disorders, Type 2 diabetes, and psychological afflictions.
Nothing to see here….really.

In the year 2018 alone, an estimated 124,000 preventable deaths in the U.S. were traced to UPF consumption, according to Eduardo Augusto Fernandes Nilson, principal investigator of this new revelation.
From a grim perspective, about 74,000 Americans perished from fentanyl overdoses in 2022.
Fernandes Nilson’s consortium employed an intricate computational model, examining health data from nearly 240,000 individuals and over 14,000 fatalities, to deduce the share of early deaths tied to UPFs.
The calculated mortality rates oscillated between 4 percent in Colombia, a nation with minimal UPF consumption, to an unsettling 14 percent in heavy-consuming countries such as the United Kingdom and the United States, as per the New York Post.
Brazil (low), Chile and Mexico (moderate), and Australia and Canada (high) were also encompassed in the study’s scope.
“The amassed evidence underscores that UPF intake substantially aggravates the global disease burden. Thus, slashing their consumption must become a cornerstone of national dietary frameworks and public health mandates,” the researchers passionately advocated.
Nevertheless, skepticism shadowed the findings. Nerys Astbury, a nutrition researcher and associate professor at the University of Oxford — detached from the study — emphasized to CNN that the investigation did not definitively prove causality between UPF ingestion and mortalities.
Further dissent came from Sarah Gallo, senior vice president for product policy at the Consumer Brands Association, representing the processed food sector. Gallo contended to The Post, “This stands as another bewildering piece of research that could deepen consumer misunderstanding. Presently, no universally accepted scientific delineation of ‘ultra-processed foods’ exists,” as per NY Post.
She cautioned, “Vilifying accessible, cost-effective, shelf-stable edibles might inadvertently curtail access to vital nutrient-rich foods, jeopardize dietary quality, escalate food-borne risks, and widen health inequities.”
