Study uncovers the basis of COVID-19-related brain fog | University of Minnesota

EXTREME and incomplete oversimplification of the many complex neurological issues caused by SarsCov2, but important facet of the vaguely defined “brain fog” of Long Covid and post-acute Covid lingering symptoms.

“Neurological symptoms have been widely observed in COVID-19 patients, with many survivors exhibiting persistent neurological and cognitive impairment. New research from the University of Minnesota found that COVID-19 triggers inflammation in the brain, which is linked to many COVID-related symptoms such as fatigue and ‘brain fog.’”

Patients recovering from COVID-19 who presented with anosmia during their acute episode have behavioral, functional, and structural brain alterations
Patients recovering from COVID-19 who presented with anosmia during their acute episode have behavioral, functional, and structural brain alterations
: “Patients who presented with anosmia exhibited more IMPULSIVE alternative changes…Anosmia correlated with brain measures, including decreased functional activity during the decision-making task, thinning of cortical thickness in parietal regions, and loss of white matter integrity.”

Here’s mine. The white spots are not supposed to be there. You can’t see the microhemorrhages or swelling.

Infected early March ‘20- pre-vaccine.But the threat is still here for everyone-vax or not, young or old.

Please mask up.”

Mounting research shows that COVID-19 leaves its mark on the brain, including significant drops in IQ scores
Mounting research shows that COVID-19 leaves its mark on the brain, including significant drops in IQ scores

In addition to brain fog, COVID-19 can lead to an array of problems, including headaches, seizure disorders, strokes, sleep problems, and tingling and paralysis of the nerves, as well as several mental health disorders. A large and growing body of evidence amassed throughout the pandemic details the many ways that COVID-19 leaves an indelible mark on the brain. But the specific pathways by which the virus does so are still being elucidated, and curative treatments are nonexistent.

SARS-CoV-2 infects neurons and induces neuroinflammation in a non-human primate model of COVID-19
SARS-CoV-2 infects neurons and induces neuroinflammation in a non-human primate model of COVID-19
“Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the etiologic agent of coronavirus disease 2019 (COVID-19), can induce a plethora of neurological complications in some patients. However, it is still under debate whether SARS-CoV-2 directly infects the brain or whether CNS sequelae result from systemic inflammatory responses triggered in the periphery. By using high-resolution microscopy, we investigated whether SARS-CoV-2 reaches the brain and how viral neurotropism can be modulated by aging in a non-human primate model of COVID-19.”

Unraveling the enigma of long COVID: novel aspects in pathogenesis, diagnosis, and treatment protocols

“The nervous system, particularly the brain, can become infected by SARS-CoV-2 early in the course of COVID-19 via viral access through the cribriform plate located at the upper part of the nose.. this route is more ominous than previously thought. The pits of the cribriform plate and areas beneath the olfactory bulb including potential spaces such as the air sinuses can be a reservoir for not only viral persistence, but also its replication.. the upper part of the nose and the structures surrounding it appear to be ideal sites for access to the CNS (central nervous system).. This can cause a low-grade inflammation in the meninges and deeper tissues in the neuronal environment triggering neuroinflammation.. [This can cause] Symptoms such as brain fog, cognitive deficits, prolonged anosmia, memory deficits, and deposition of amyloid-like fibrils that cause premature aging in patients with long COVID.."

It's certainly ominous that SARS-CoV-2 can infect my brain instantly and silently.”
