What We Know About Covid’s Impact on Your Brain?
Brain shrinkage is observed even in mild or asymptomatic cases of Covid and impacts cognition.
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.
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.”
How long COVID could lift the fog on neurocognitive disorders
‘I’m a shell of myself. My physical issues aren’t half as bad as my brain problems. You can say brain fog, but that doesn’t come close to doing it justice.’”

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.”
Research Shows Severe COVID-19 Contributes to Long-Lasting Cognitive Impairment - InventUM
“We found persistent subjective and objective cognitive issues even two years after infection, including brain fog, word-finding problems, working memory deficits and reduced processing speed.” “Most Patients Have Never Fully Recovered”

Scientists are worried that persisting cognitive issues may signal a coming surge of dementia and other mental conditions
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.
Low Cortisol Levels May Be Key to Long COVID Symptoms
Yet another stretch for one size fits all explanation of a multifaceted condition. Still, important finding:
“A groundbreaking study from the University of Colorado Boulder has uncovered a potential mechanism behind the persistent neurological symptoms experienced by many Long COVID sufferers. The research, published in Brain, Behavior, and Immunity, points to a significant drop in cortisol levels in the brain as a possible culprit, offering new insights into this complex and widespread condition.”
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.’”
