‘Brain fog’ from long Covid has measurable impact, study suggests
“Researchers found that deficits equivalent to six IQ points were detectable a year or more after infection”
Mounting research shows that COVID-19 leaves its mark on the brain, including significant drops in IQ scores

Virus that causes COVID-19 uses a secret 'back door' to infect the brain
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.
Neuroinvasion and anosmia are independent phenomena upon infection with SARS-CoV-2 and its variants
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.

COVID-related loss of smell tied to changes in the brain | CIDRAP
“On MRI conducted during the game, loss of smell was associated with decreased functional activity during decision-making, loss of white-matter integrity, and thinning of the outer layer of the cerebrum in the parietal regions (responsible for processing sensory input, understanding spatial relationships, and how to navigate).”
Brain effects of mild COVID-19 in healthy young adults: A pilot study
“Our pilot data suggests that mild COVID-19 may result in brain pathology and impact neurocognitive function in younger adults in a manner parallel to prior findings in older individuals. Though findings may not generalize to other SARS-CoV-2 variants, larger longitudinal studies of mild COVID-19 should be undertaken to understand the potential clinical implications of these findings over the longer term.”

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.’”
Internal tremors and vibrations in long COVID: a cross-sectional study
"Most people associate symptoms such as shaking or trembling movements with neuromuscular diseases, such as Parkinson’s disease—but now, some Long COVID patients have reported experiencing internal tremors and vibrations."

Para-infectious brain injury in COVID-19 persists at follow-up despite attenuated cytokine and autoantibody responses
“ COVID-19 results in acute elevation of serum markers of brain injury”
Millions of people have long COVID brain fog — and there's a shortage of answers
"COVID. That, too, can basically be a cause of a brain injury."
SARS-CoV-2 is associated with changes in brain structure in UK Biobank
UK researchers scanned the brains of 400 people before and after mild covid, compared them with controls and found:
- greater reduction in grey matter thickness
- greater reduction in global brain size
- greater cognitive decline
- greater change to primary olfactory cortex
