Researchers recently expressed concern about a lingering COVID-19 symptom — brain fog.

What is brain fog?

Brain fog is a new symptom that has been seen in recovered COVID-19 patients.

Dr. Shruti Agnihotri, a neurologist at the University of Alabama Birmingham, told ABC 33/40 that she has spoken with several patients about the condition, in which people suffer from severe headaches and memory loss.

  • “Often times these patients may have even recovered from the initial fever and shortness of breath symptoms and they continue to have very severe headaches and tend to often complain about memory loss, often referred to as a brain fog.”

The symptoms are similar to what people see during a concussion, she said.

  • “Patients often times describe difficulty with attention, focus, just not feeling right, not as sharp as they have otherwise been. We sometimes see these symptoms in many other conditions, during post-concussion, and we also see them after various other infections too,” Agnihotri told ABC 33/40.
