CHICAGO — In what is thought to be the first study of its kind, Northwestern doctors found high levels of neurological symptoms among patients who developed long-term COVID-19 symptoms after a relatively mild initial illness that did not require hospitalization.

Eight-five percent of patients reported four or more neurological symptoms, problems such as “brain fog” (or attention and memory problems), loss of taste or smell, headache and blurred vision. In addition, patients experienced non-neurologic symptoms, such as fatigue (85%) and depression or anxiety (47%).

About half of patients in the study missed more than 10 days of work, due to what doctors call long COVID syndrome, or symptoms lasting more than six weeks.
