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.”

Long COVID: SARS-CoV-2 spike protein accumulation linked to long-lasting brain effects
Long COVID: SARS-CoV-2 spike protein accumulation linked to long-lasting brain effects
“The study shows that the SARS-CoV-2 spike protein remains in the brain's protective layers, the meninges, and the skull's bone marrow for up to four years after infection. This persistent presence of the spike protein could trigger chronic inflammation in affected individuals and increase the risk of neurodegenerative diseases.”

Persistence of spike protein at the skull-meninges-brain axis may contribute to the neurological sequelae of COVID-19
Persistence of spike protein at the skull-meninges-brain axis may contribute to the neurological sequelae of COVID-19

Evidence that a COVID-19 infection can induce neurological sequelae.

The SARSCoV2 spike protein can persist in the brain—skull bone marrow and meninges—to induce neurologic damage

SARS-CoV-2 spike protein accumulates & persists in the body for years after infection, especially in the skull-meninges-brain axis, potentially driving long COVID. mRNA vaccines help but cannot stop it.

In mice, it caused inflammation, anxiety, and worsened brain injuries. Vaccines reduced but did not fully eliminate it.

Cross-Section of Neurological Manifestations Among SARS-CoV-2 Omicron Subvariants—Single-Center Study

“The Omicron variant of SARS-CoV-2 presents a wide spectrum of neurological manifestations."

"Although there is an improvement in the survival rate of patients with COVID-19, the frequency of neurological manifestations increases."

"The occurrence of delirium, cerebrovascular diseases, and ischemic stroke results in higher mortality."

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.

SARS-CoV-2 Invasion and Pathological Links to Prion Disease
SARS-CoV-2 Invasion and Pathological Links to Prion Disease

Nearly half of those infected with SARS-CoV-2 experience long-term neurological problems, including brain fog and memory issues.

An infection may accelerate or exacerbate prion diseases like Creutzfeldt–Jakob disease, leading to rapid neurodegeneration.

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.”

COVID survivors may develop dementia
COVID survivors may develop dementia

“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.."

COVID-19 survivors show signs of significant cognitive deficits which could become dementia even a year after having the virus1. They also have an increased risk of depression, anxiety and disrupted sleep.

Advanced brain fMRI showed low glutathione : r/covidlonghaulers

“Hey all. I thought I would just throw this out there. I had an advanced brain fMRI that was able to show a bunch of brain biomarkers. The only significant finding was that I had low brain glutathione. I was at .56 mM and the normal range is 1-2 mM. He told me this is a large deficiency.

He said this would usually indicate CFS, brain fog, and low energy.”

“In COVID-19 survivors, the MR susceptibility increased in the medulla, pons and midbrain regions of the brainstem. Specifically, there was increased susceptibility in the inferior medullary reticular formation and the raphe pallidus and obscurus. In these regions, patients with higher tissue susceptibility had worse acute disease severity, higher acute inflammatory markers, and significantly worse functional recovery.”
