Nearly a third of hospitalized Covid-19 patients experienced some type of altered mental function — ranging from confusion to delirium to unresponsiveness — in the largest study to date of neurological symptoms among coronavirus patients in an American hospital system.
After they were discharged, only 32 percent of the patients with altered mental function were able to handle routine daily activities like cooking and paying bills, said Dr. Igor Koralnik, the senior author of the study and chief of neuro-infectious disease and global neurology at Northwestern Medicine.
