Covid and Brain Damage
Physical, psychological and cognitive profile of post-COVID condition in healthcare workers, Quebec, Canada
"Persistent cognitive and other professionally-disabling sequelae of COVID-19 in essential workers could have critical implications for quality healthcare delivery during and after the pandemic."
Memory loss and 'brain fog' may be side effects of COVID-19, new study shows
Study: Long-term COVID-19 side effects could include memory loss and other cognitive dysfunctions.
Most common cognitive deficits: memory encoding and memory recall, which showed up in 24% and 23% of the participants, respectively.
What Drives Post-COVID Cognitive Changes?
Covid brain damage: Millions have persistent cognitive issues after SARS-CoV-2 due to vascular injury...even young & healthy who had mild case.
"However, there are not yet effective laboratory tests or treatments for COVID-associated cognitive changes."
SARS-CoV-2 spike protein induces cognitive deficit and anxiety-like behavior in mouse via non-cell autonomous hippocampal neuronal death
"Our behavioral study showed that administration of SARS-CoV-2 spike protein S1 subunit to mouse hippocampus induced cognitive deficit and anxiety-like behavior in vivo. These neurological symptoms were accompanied by neuronal cell death."
'They can’t think': Covid patients suffer memory problems months after recovering
As many as 24% of people who have recovered from Covid-19 continue to experience cognitive difficulties, including problems w/memory, multitasking, processing speed & focusing, researchers at the Icahn School of Medicine at Mount Sinai reported Friday:
COVID-19-related encephalopathy presenting with aphasia resolving following tocilizumab treatment
"COVID-19-related encephalopathy may present with early language disturbances.
Cytokine-mediated neuroinflammation has been suggested as the underlying mechanism"
COVID-19-related encephalopathy presenting with aphasia:
Encephalopathy in COVID-19 Presenting With Acute Aphasia Mimicking Stroke
"reversible COVID-19-related encephalopathy presenting as acute aphasia, mimicking stroke or status epilepticus, eventually evolving into delirium...our case suggests that focal neurological deficits may occur as the earliest feature of encephalopathy"

Read this thread. Any Covid infection can lead to Alzheimer’s-like brain damage.
There will be no herd immunity. Reinfection happens on average in 16 mos.
We also know it causes organ damage, clots & T-cell decrease.
We’ve barely begun to see what Covid infection means long term.
COVID-19 survivors may suffer from loss of gray matter over time: study
Gray matter is part of our central nervous system & essentially controls ALL our brain's functions...It enables us to control movement, memory, & emotions, so an abnormality in the gray matter of the brain can affect communication skills & brain cells.
Study links even mild Covid-19 to changes in the brain | CNN
"People who have even a mild case of Covid-19 may have accelerated aging of the brain and other changes to it...the brains of those who had Covid-19 had a greater loss of gray matter and abnormalities in the brain tissue compared with those who didn't:"
Even Mild Cases of COVID May Leave a Mark on the Brain
Team saw marked differences in gray matter between those who had gotten /COVID-19 & those who hadn't. Thickness of gray matter in frontal & temporal lobes was reduced in COVID-19 group, differing from typical patterns seen those that hadn’t had COVID-19.
