“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.
“Post-Covid cognitive impairment affects daily function and quality of life. • ACE-III fails to detect cognitive impairment in most post-Covid patients. • 89% of patients have impaired attention, executive function, processing speed on novel tests. • New tests are needed for post-Covid cognitive assessment in clinical practice.”
“COVID-19 may Enduringly Impact cognitive performance and brain haemodynamics in undergraduate students”
“37 % of the undergraduates exhibited impaired cognition up to 17 months post-infection.”
Older adults recovering from COVID-19 face a 58% higher risk of developing dementia compared to those uninfected, with rates peaking 12 months post-infection.
Study reviewed 11 studies, 940k cases, 6.8M controls.
“The buddy from college I talk about every now and again.
He’s prolly 50 or so. He posted this a few days ago. He has already had a rough go of it, he has a daughter he is devoted to, and who loves him immensely.
I am as sad as I am angry. “
“Worse, most people don’t even notice it has happened to themselves.
But I can tell you we who continue to mask and have many fewer COVID infections can see the growing cognitive damage in more and more people around us.
Memory problems, like recall and word finding delays. Weakness and fatigue and motor control impairment. Growing executive function and emotional regulation deficits.
More and more friends disables and forced out of work or school by Long COVID symptoms.
It’s scary to witness the broad societal decline, and dispiriting to see so many governments and Public Health agencies persist in minimizing the growing problem.”
Covid itself causes cognitive impairment. From 2020, prior to Covid vaccination of any kind:
“In our cohort of COVID-19 patients neurologic manifestations were frequent, including cognitive impairment.”
“COVID-19 survivors show signs of significant cognitive deficits which could become dementia even a year after having the virus.. The team [in India] found that more than 80% of people tested reported at least one of four symptoms – depression, anxiety, stress and insomnia – ranging from mild to severe.. At least 6.1% of the patients were diagnosed with mild cognitive impairment and 4% developed dementia. More than 60% of the patients experienced a loss of taste and smell during the active phase of the infection. This could alter the function of brain areas linked to cognitive ability and emotional well-being.."
