SARS-CoV-2 and HSV-1 Induce Amyloid Aggregation in Human CSF Resulting in Drastic Soluble Protein Depletion
SARS-CoV-2 and HSV-1 Induce Amyloid Aggregation in Human CSF Resulting in Drastic Soluble Protein Depletion

SARS-CoV-2 and HSV-1 induce amyloid aggregation, depleting soluble proteins.

Suggests a link between viral infections and neurodegenerative diseases via protein loss.

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.

“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."

Brain-wide alterations revealed by spatial transcriptomics and proteomics in COVID-19 infection
“We identified dysregulation of mitochondrial and synaptic pathways in deep-layer excitatory neurons and upregulation of neuroinflammation in glia, consistent across both mRNA and protein. Remarkably, these alterations overlapped substantially with changes in age-related neurodegenerative diseases, including Parkinson’s disease and Alzheimer’s 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.

Pioneering discovery and therapeutics at the brain-vascular-immune interface

A new paper in Cell, “Pioneering discovery and therapeutics at the brain-vascular-immune interface,” describes COVID-19 as a neurological disease alongside multiple sclerosis, Alzheimer’s, stroke and traumatic brain injury.

“COVID-19 can accelerate progression of dementia and induce BBB disruption and inflammatory blood clots causally linked with neuroinflammation and neuronal loss.8 In neurodevelopmental disorders, prematurity and perinatal hypoxia that trigger brain hemorrhage and BBB disruption are risk factors for cerebral palsy, intellectual disability, and autism. Collectively, these risk factors highlight the interconnected vascular and immune triggers of neurological diseases.”

“‘…there is evidence of fragments or an inflammatory kind of a massive inflammatory response that occurs triggered by COVID. And those inflammatory markers we tend to notice in the brain.’

And that could cause something called COVID-19 Cognitive Impairment.

‘And we are going to compare people with COVID cognitive impairment. To be clear on this, I think that COVID can cause cognitive impairment and maybe even dementia…’”
