The most comprehensive molecular study to date of the brains of people who died of COVID-19 turned up unmistakable signs of inflammation and impaired brain circuits.

Investigators at the Stanford School of Medicine and Saarland University in Germany report that what they saw looks a lot like what's observed in the brains of people who died of neurodegenerative conditions such as Alzheimer's disease and Parkinson's disease.

The findings may help explain why many COVID-19 patients report neurological problems. These complaints increase with the severity of infection with SARS-CoV-2, the virus that causes COVID-19. And they can persist as an aspect of "long COVID," a long-lasting disorder that sometimes arises following infection. About one-third of individuals hospitalized for COVID-19 report symptoms of fuzzy thinking, forgetfulness, difficulty concentrating and depression, said Tony Wyss-Coray, PhD, professor of neurology and neurological sciences at Stanford.

Yet the researchers couldn't find any signs of SARS-CoV-2 in brain tissue they obtained from eight individuals who died of the disease. Brain samples from 14 people who died of other causes were used as controls for the study.
