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.”

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.”

MRI Reveals Significant Brain Abnormalities Post-COVID - Neuroscience News
"Neuroimaging study reveals significant brain changes in areas associated with language comprehension, cognition, and circadian rhythm control six months after COVID-19 infection."
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."
