New Evidence Suggests Long COVID Could Be a Brain Injury

'As part of the preprint study, participants took a cognition test with their scores age-matched to those who had not suffered a serious bout of COVID-19. Then a blood sample was taken to look for specific biomarkers, showing that elevated levels of certain biomarkers were consistent with a brain injury. Using brain scans, researchers also found that certain regions of the brain associated with attention were reduced in volume.

Patients who participated in the study were "less accurate and slower" in their cognition, and suffered from at least one mental health condition, such as depression, anxiety, or posttraumatic stress disorder, according to researchers.

The brain deficits found in COVID-19 patients were equivalent to 20 years of brain aging and provided proof of what doctors have feared: that this virus can damage the brain and result in ongoing mental health issues. 

"We found global deficits across cognition,"'
