Hamsters with long Covid exhibits a neurodegenerative signature in the brainstem
Hamsters with long Covid exhibits a neurodegenerative signature in the brainstem
“Using the golden hamster as a model, we provide further evidence that SARS-CoV-2 is neuroinvasive and can persist in the central nervous system, as we found viral RNA and replicative virus in the brainstem after 80 days of infection.”

Association between COVID-19 infection and new-onset dementia in older adults: a systematic review and meta-analysis - BMC Geriatrics

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.

Limbic system damage following SARS-CoV2 infection | Brain Communications | Oxford Academic

Limbic system damage from Covid:

SARS-CoV-2 is a neurotropic virus that may cause long-term neurological symptoms by damaging the limbic system.

This research shows that COVID-19 can impair emotion recognition, memory, and olfactory abilities, with altered brain connectivity patterns.

Worse, most people don’t even notice it has happened to themselves.

“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.”

Whoopi Goldberg Commiserates With Fellow-Covid Sufferer Joe Biden: “Sometimes I Go For A Word And It’s Not There”
Whoopi Goldberg Commiserates With Fellow-Covid Sufferer Joe Biden: “Sometimes I Go For A Word And It’s Not There”

Whoopi Goldberg, who just had her 4th COVID infection, joked about her post infection brain damage on TV.

“I’m just getting over COVID – again – and I can barely remember anybody’s name. There are times when I go for a word and it’s not there.”

“A new study in eClinicalMedicine has found that healthy volunteers infected with SARS-CoV-2 had measurably worse cognitive function for up to a year after infection when compared to uninfected controls. Significantly, infected controls did not report any symptoms related to these cognitive deficits, indicating that they were unaware of them.”

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.’”
