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.
Even mild COVID can cause brain shrinkage and affect mental function, new study shows
“Brain changes including shrinkage, weakened connections and poorer performance on thinking and memory tests could explain ‘brain fog’ after COVID – even after ‘mild’ cases.”
Cognitive deficits after COVID-19 associated with brain injury biomarkers and volume loss
“Cognitive deficits after COVID-19 associated with brain injury biomarkers and volume loss”
The study found that patients hospitalized with COVID-19, both with and without acute neurological complications, had worse cognitive scores than expected for their age, sex, and education level. These cognitive deficits were observed across all cognitive domains tested. The cognitive impairment was associated with increased levels of brain injury biomarkers in the blood and reduced volume of a specific brain region (the anterior cingulate cortex) on MRI scans. Factors like the severity of the initial COVID-19 illness and the presence of acute confusion (encephalopathy) were linked to the worst cognitive scores.

“But this week 2 new publications have substantially added to our understanding of the extent that Covid can impair cognitive function across the full gamut— from young, healthy individuals with mild infections to older, hospitalized patients with severe Covid.”

Gray matter thickness may be reduced in specific brain areas after SARS-CoV-2 Omicron infection
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
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.”

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
COVID-19 Linked to Significant Brain Changes, Shrinkage
Covid linked to significant brain shrinkage: "Even a mild COVID-19 infection can change the brain. People infected had a greater reduction in brain volume and performed worse on cognitive tests than those who did not contract COVID-19."
Selective visuoconstructional impairment following mild COVID-19 with inflammatory and neuroimaging correlation findings
"investigate adults at least four months after recovering from mild COVID-19...In approximately 1/4 of mild-COVID-19 individuals, we detected a specific visuoconstructive deficit, which was associated with changes in molecular and structural brain imaging"

"Colin Furness, an epidemiologist in Toronto, says that EVERYBODY that gets COVID-19 deals with some brain tissue loss. The question, he says, is how much."

COVID-19 survivors may suffer from loss of gray matter over time: study
Gray matter is part of our central nervous system & essentially controls ALL our brain's functions...It enables us to control movement, memory, & emotions, so an abnormality in the gray matter of the brain can affect communication skills & brain cells.

"People who have even a mild case of Covid-19 may have accelerated aging of the brain and other changes to it...the brains of those who had Covid-19 had a greater loss of gray matter and abnormalities in the brain tissue compared with those who didn't:"
Even Mild Cases of COVID May Leave a Mark on the Brain
Team saw marked differences in gray matter between those who had gotten /COVID-19 & those who hadn't. Thickness of gray matter in frontal & temporal lobes was reduced in COVID-19 group, differing from typical patterns seen those that hadn’t had COVID-19.

"A recent Nature study of 785 people ages 51 to 81 found those who had COVID-19 lost more grey matter and had more brain shrinkage than those who had not."
