Originally identified as a respiratory disease, some COVID-19 patients exhibit neurologic symptoms including stroke, loss of consciousness, headache, and even the loss of taste and smell. What's unknown is whether these are direct effects of the virus entering the nervous system, or consequences of the disease's effect on the body.

On the Mayo Clinic Q&A podcast, Dr. Allen Aksamit Jr., a Mayo Clinic neurologist, discusses potential neurological effects of COVID-19.
