Small study reveals details of brain damage in COVID-19 patients

Massachusetts General Hospital researchers examined six patients using a specialized magnetic resonance technique and found that COVID-19 patients with neurological symptoms show some of the same metabolic disturbances in the brain as patients who have suffered oxygen deprivation from other causes.
