Covid and Brain Damage
Study on 61 men MRI scanned pre and post omicron covid. "Decrease in gray matter thickness in the left precuneus and right lateral occipital regions of the brain. Ratio of the right hippocampus volume to total brain volume decreased."
Average age of man in study: 43

More loss of smell and taste, insomnia and pronounced anxiety are new symptoms of latest Covid variant as the virus continues to mutate unrestrained, is neuroinvasive, persists in the body and has multiple effects on the brain:
Just published @Nature How fibrin drives brain inflammation in acute and #LongCovid and that a monoclonal antibody to fibrin protects against microglial activation
Not a cold.
A mutation in the Spike Protein of SARS-CoV-2 could help it infect brain cells using a secret “back door” after entering the central nervous system.
SARS2 can invade your brain.
All variants are neuroinvasive.
Neuroinvasion and anosmia are independent phenomena upon infection.
SARS2 can travel retrogradely and anterogradely along axons in neuron-epithelial networks.

'The new collaborative study between scientists at Northwestern University & the Univ. of Illinois-Chicago uncovered a series of mutations in the SARS-CoV-2 spike protein..'
“new study has added fuel to concerns that America could face a surge in dementias in coming years & decades due to COVID.”
“Changes in blood flow could cause frequent, small injuries to brain tissue, depriving oxygen often enough to cause.. dementia.”

New findings in JAMA Psychiatry find that levels of mental illness such as depression, anxiety and self-harm are elevated after a COVID-19 diagnosis
NIH study on 7 Neuro-PASC patients (ages 42-63) found 71% of initial abnormalities, like autonomic and immunologic issues, persisted after 1 year.
Persistent signs include central catecholamine deficiency and MRI changes.
“‘…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…’”
