1) Martha Exck and colleagues did a large online survey of 2,125 patients with ME/CFS and 1,800 with Long COVID on what interventions they find useful or harmful. The study was partly supported by the Open Medicine Foundation (OMF)

“Next time you think of dismissing COVID as just another.. common cold it may pay to visualise what you see so starkly in this paper, the virus moving freely around your body & finding long-term home.. where it can really cause trouble, including the brain & heart.” #LongCovid

The hygiene hypothesis is being eroded Infections at a young age correlate with severe infections later in life, few infections in youth correlate with less infections in adulthood Where was the “strengthening of kids immune system” from infections? cidrap.umn.edu/antimicrobial-…

'The virus that causes COVID-19, known as SARS-CoV-2, may also make the brain vulnerable to Alzheimer's'. It's very important to think through the population-level effects this will have in the next decade. health.harvard.edu/mind-and-mood/…

Linus Pauling (Nobel prize winner) though that the benefits of vitamin C extended beyond just treating scurvy and theorized that it could treat colds and even cancer. He was essentially 'cancelled' for these ideas. It blows my mind that scientists think they have it all figured

I’ve spent two decades studying how brains age. And I’ve never seen anything quite like this. In normal aging, some neurons die—but it’s gradual, region-specific, and the brain compensates remarkably well. Most of what we see is driven by loss of synaptic connections, not

Not only does COVID cause lymphocytopenia like HIV, we now know it also causes hypogammaglobulinemia like primary immune deficiency CVID. Reduced immuneglobulin antibodies is a feature of COVID Acquired Immune Deficiency (CoV-AIDS). This is found in patients with chronic

The consequences. Persistence of the virus in tissues (gut, brain, lymph nodes) T cell exhaustion and shifts in immune balance Neurological effects - the same pathways implicated in Alzheimer’s and Parkinson’s are disrupted during infection

Detection of spike protein months later suggests persistent viral antigen release - likely from tissue reservoirs (gut, endothelium, immune cells). Microclot formation appears linked to this ongoing antigenemia and chronic microvascular inflammation.

“We may be witnessing the emergence of a population-level acquired immune deficiency — not sexually transmitted, but airborne.” That line isn’t from a tweet. It’s from a peer-reviewed paper in AJPM Focus (2025). A short thread 🧵 on why this framing matters 👇

I keep hearing about whole classes of school kids out with flu. Twenty to thirty kids at a time. It's almost like their immune systems have been weakened or something. And there it is in the data:

These are not random MRI quirks. These are exactly the changes you’d expect from a virus whose proteins block ribosomes, overload glia, and destabilize neuronal metabolism. Time is passing - and we still refuse to learn from the biology of viruses (proteins) like HIV.

In that sense, cognitive PASC is HAND-like. SARS-CoV-2 proteins can drive the same neuroimmune circuits that make HIV-associated cognitive disorders possible - even without needing direct neuronal infection. Státní zdravotní ústav Ministerstvo zdravotnictví Adam Vojtěch

⚠️ Why Covid Cancers are ignored by MSM, Public health, doctors and AI? The answer is here ⤵️ There’s a disconnect between the "standard" public health narrative and what clinicians like Dr. Kashyap Patel and his colleagues are documenting on the ground. By 2026, the data from

This isn’t a new comparison. For years, parallels between NeuroHIV and neuro-COVID/Long COVID have been discussed across fields. What’s new is that they are now formally described as shared CNS mechanisms, not just analogy!🧵

MCAS: When “Trying Everything” Fails Most refractory MCAS patients have not truly failed treatment as they’ve likely been treated within a narrow framework. Antihistamines and stabilizers often fail when you never ask the question - why mast cells are activated at all 🧵
