This morning I reviewed dozens of #COVID19 studies published in the last five days. Here's what you should know:
- A multimodal MRI study found “altered signal intensity, abnormal tissue microstructure, and imbalanced neurochemicals” in the brains of people with BOTH long COVID AND COVID-19 recovered healthy controls, demonstrating “long-term neurological effects of COVID-19.” 1/6

in reply to Augie Ray • • •- A study of people with post-COVID cognitive issues found “distinct brain structural alterations and ONGOING neurodegenerative processes.”
- A study found that “SARS-CoV-2 infection causes a low-grade inflammatory process that, even months or years after infection, does not return to pre-COVID-19 levels, which may contribute to neurologic sequelae and accelerated aging.” 2/6

in reply to Augie Ray • • •- Another study found “prolonged T cell dyshomeostasis” (damage to your immune system) due to “persistent activation and dyshomeostasis of CD4+ and CD8+ T cells for 6–12 months after acute infection.”
- A study found “Persistent pulmonary inflammation… following mild-to-moderate COVID-19 and associated with increased vascular inflammation… potentially contributing to elevated cardiovascular risk.”

in reply to Augie Ray • • •- A study found that cardiovascular risks were significantly elevated in the weeks after a COVID diagnosis and “remained elevated to beyond 12 months for venous thromboembolism (1·39x risk), thrombocytopenia (1·42x risk), and myocarditis or pericarditis (1·42x risk).”
- A study of children, 73% of whom had a history of mild COVID-19, found 47% had impaired lung function.

in reply to Augie Ray • • •- A study of retinal microvasculature of recovered COVID-19 patients found significant changes compared to controls that “may lead to future complications or visual impairment.”
- A study of those with Long COVID found “significant alveolar gas exchange impairment, with frequent diffusion deficits, fibrotic changes, and ground-glass opacities indicating persistent parenchymal and microvascular injury.”
