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.

“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.”

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
