(WBBM NEWSRADIO) —A study by a neurologist at Northwestern Medicine has identified some trends among people who suffer relatively mild cases of COVID-19 but experience symptoms that last far longer than in most patients.
Dr. Igor Koralnik, chief of Neuro-infectious Diseases and Global Neurology at Northwestern, has studied 100 people who didn't have serious enough COVID symptoms to be hospitalized but whose symptoms in some cases lasted for several months.
Those symptoms include brain fog, headaches, dizziness, numbness, tingling, ringing in the ears and loss of taste or smell.
"Patients reported impaired quality of life,” Koralnik said.
Koralnik says research continues into several findings. They include women making up about 70% of the patients reporting these symptoms; a possible link between depression or anxiety to lingering symptoms, and some patients reporting COVID vaccines causing the symptoms to get more severe for a time.
The study was published in the Annals of Clinical and Translational Neurology.
