Many Covid 19 patients experience neurological symptoms, such as speech and memory disorders or depression, after severe courses of the disease. So far, however, little is known about what exactly the coronavirus does in the brain. A team of researchers from Saarland University and Stanford University has found that immune and barrier cells in the brain are activated in severely ill covid patients.

The other cells affected by this show similar characteristics in the active genes as in schizophrenia, depression and other cognitive diseases. The study has now been published in the renowned journal Nature.
