Milder COVID-19 infection could still leave brain with lasting impact: UK study

Mild cases of COVID-19 could also leave a lasting impact on the human brain, according to a recent study.
In August, researchers from England's University of Oxford and the Imperial College of London wrote that brain imaging from the UK Biobank – including the data from more than 40,000 people in the United Kingdom, dating back to 2014 – showed differences in gray matter thickness between those who had been infected with COVID-19 and those who had not.
The team said that using both hypothesis-driven and exploratory approaches, with false discovery rate multiple comparison correction, they had identified respectively 68 and 67 significant longitudinal effects associated with SARS-CoV-2 infection in the brain.
In the COVID-19 group, gray matter tissue was reduced in the frontal and temporal lobes, and in the general population changes to gray matter volume were larger than normal in the 401 who had been infected.
