How does COVID-19 affect the brain?
Megakaryocytes are showing up in the brains of people who died of COVID-19, which may help explain some of the neurological problems associated with the disease, researchers say.
In some patients who died of COVID-19, the brain capillaries contained megakaryocytes, large cells which normally reside in the bone marrow and make platelets, said study leader Dr David Nauen of Johns Hopkins University.
