“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.

“Today, @CNN, @UW decided to publish a story on a study purposefully designed to produce lies funded by @JeffBezos with the intention of lying to the public to convince them that schools closing for a few weeks in 2020 caused changes in the brains of children.”

A thread with multiple studies:

UK researchers scanned the brains of 400 people before and after mild covid, compared them with controls and found:

1. greater reduction in grey matter thickness
2. greater reduction in global brain size
3. greater cognitive decline
4. greater change to primary olfactory cortex
