"The team found marked differences in gray matter – or the neurons that process information in the brain – between those who had been infected with COVID-19 and those who had not. Specifically, the thickness of the gray matter tissue in brain regions known as the frontal and temporal lobes was reduced in the COVID-19 group, differing from the typical patterns seen in the people who hadn’t had a COVID-19 infection.
In the general population, it is normal to see some change in gray matter volume or thickness over time as people age. But the changes were more extensive than normal in those who had been infected with COVID-19."
"When Ziyad Al-Aly’s research team told him how often diabetes appeared to strike Covid-19 survivors, he thought the data must be wrong, so he asked his five colleagues to crunch the numbers again.
Weeks later, they returned the same findings after sifting through millions of patient records. By then Al-Aly had also gone digging into the scientific literature and was starting to come to terms with an alarming reality: Covid-19 isn’t just deadlier for people with diabetes, it’s also triggering the metabolic disease in many who didn’t previously have it."
Children under the age of five infected with SARS-CoV-2 produce lower levels of some immune cells than older children and adults do.
