Image of a brain Brain and muscle chemistry in myalgic encephalitis/chronic fatigue syndrome (ME/CFS) and long COVID: a 7T magnetic resonance spectroscopy study "The changes in lactate in ME/CFS are consistent with the presence of energetic stress and mitochondrial dysfunction. A reduction in total choline in long COVID is of interest in the context of the recently reported association between blood clots and 'brain fog', and earlier animal studies showing that choline might prevent intravascular coagulation. Importantly, differences in findings between ME/CFS and long COVID suggest that the underlying neurobiological mechanisms, while leading to similar clinical presentations, may differ."

Begs the obvious followup of looking at subsequent cohorts, who did not experience pandemic protocols, for whom any outcome deficits will be explainable only by #CovidBrain and other #LongCovidKids sequelae.
Of course, their willful ignorance of the potential of #VirusFreeAir is just plain immoral.

News Release 5-Mar-2026 How viruses mess with our brains A team from the UNIGE and the HUG reviewed 900 scientific articles to better understand the impact of viruses on memory, attention, and concentration. Peer-Reviewed Publication Université de Genève FacebookXLinkedInWeChatBlueskyMessageWhatsAppEmail What impact does a viral infection have on our memory, attention, and concentration? The COVID-19 pandemic has reignited interest in this question, which has now been extended to other infections such as HIV, herpes, and hepatitis. A team from the University of Geneva (UNIGE) and Geneva University Hospital (HUG) reviewed over 900 scientific articles exploring the links between the immune system and cognitive functions. This analysis, published in Neuroscience & Biobehavioral Reviews, has identified several biological markers associated with cognitive decline in the context of infection. It also provides a solid foundation for future research.

Multimodal imaging suggests potential immune-vascular contributions to altered regional brain perfusion and oxygen metabolism in Post-COVID-19 Syndrome — Martins et al. "this study demonstrates that PCS is associated with regionally specific alterations in cerebral perfusion and oxygen metabolism. These findings support a dual process model in which hippocampal hypermetabolism seems to reflect compensatory adaptation, while ACC neurovascular uncoupling might derive from neuroimmune disruption." "findings identify the ACC as a metabolically vulnerable hub in PCS"

News Release 10-Feb-2026 Long COVID linked to Alzheimer’s disease mechanisms Diseases cause damage in some of the same ways Peer-Reviewed Publication NYU Langone Health / NYU Grossman School of Medicine FacebookXLinkedInWeChatBlueskyMessageWhatsAppEmail The increased size of, and lesser blood supply to, a key brain structure in patients with Long COVID tracks with known blood markers of Alzheimer’s disease and greater levels of dementia, a new study finds. Led by NYU Langone Health researchers, the study concerns the choroid plexus (CP), a network of blood vessels lined by cells that produce cerebrospinal fluid, which cushions the brain and forms a protective barrier between the fluid and the bloodstream. The CP regulates immune system responses (inflammation) and waste clearance in the brain. Past studies show that the COVID-19 virus can damage the cells lining CP blood vessels. Published online Feb. 10 in Alzheimer's & Dementia, the new work found that patients reporting Long COVID had a 10% larger CP than those who had fully recovered from an initial infection with SARS-CoV-2, the virus that causes COVID-19 disease. Further, CP size increases tracked with blood levels of proteins that increase as Alzheimer’s disease worsens, such as pTau217, and with blood levels of others that rise in response to brain injury, like glial fibrillary acidic protein.

Functional Limitations and Illness-Related Absenteeism among School-Aged Children with and without Long COVID, United States, 2022–2023 - Volume 32, Supplement—February 2026 - Emerging Infectious Diseases journal - CDC — Nicole D. Ford et al. On the basis of the weighted samples, we estimated 1,538,000 (1.4%) school-aged children had long COVID at some point." "69.7% were 12–17 years of age, 59.4% were female and 40.6% were male, and 35.2% were experiencing long COVID symptoms at time of survey." "Compared with children who never had long COVID, children who had long COVID had a higher prevalence of functional limitations across 5 of the 6 functional domains."

"the peak ACTH and cortisol responses to CRH and their recovery levels at 120 min were nearly normal, failing to detect clear HPA axis abnormalities."
