“Thread: A molecular clue to Long COVID “brain fog”
1/ New study from Yokohama City Univ used PET imaging of AMPA receptors. Long COVID patients showed elevated AMPAR levels, linked to both cognitive impairment and inflammation. A molecular biomarker emerges.”
“Covid damages the part of your brain (frontal lobe) which is responsible for empathy, emotional regulation & overcoming self-centeredness.
This will facilitate immorality.
Each & every infection you have causes damage.
Many are on infection 4 (or more).
Signed, a neurologist.”
How does a transient viral infection like COVID lead to long lasting neurologic symptoms?
In humans and in animal models, SARS-CoV-2 can damage peripheral sensory nerves in the nose, leaving behind debris that can then trigger inflammation in brain microglia for weeks to months after infection, which can then lead to post-viral neurological symptoms like cognitive dysfunction (brain fog).
The peripheral neuron-to-microglia axis offers a potential explanation for persistent inflammation seen in conditions like Long COVID and ME/CFS.
“Let’s talk about COVID, brain damage & society.
Specifically, what happens when a neurotropic virus repeatedly infects the population, targeting the frontal lobe & almost nobody talks about the consequences?
This thread is for the skeptics.
I’m a neurologist, stay with me 🧵”
“significant memory and executive function decline lasting up to a year, despite no reported subjective symptoms, prompting new questions about the virus’s long-term cognitive effects.”
“Brain fog may gradually evolve into a slight memory problem, difficulty finding the right word for things, objects, situations and then registering new information.”
A widely held notion is that SARS2 activates our immune systems, causing an inflammatory response in the brain.
