Omicron variant symptoms: Rare COVID symptom returns with omicron

Reports from the UK suggest that a common COVID-19 symptom has returned for the omicron variant – brain fog.

The Daily Express – a UK media outlet – recently reported that COVID-19 patients reported ‘brain fog’ as one of their symptoms in the ZOE COVID Study app, which records and analyzes symptoms such as reported by patients.

  • “One of the most unusual – but surprisingly common – symptoms of Omicron is something called brain fog,” reports the Daily Express.

Brain fog has been a somewhat rare COVID-19 symptom for some time now. In fact, reports of brain fog emerged in October 2020, well at the start of the first year of the pandemic, as I wrote for the Deseret News. But it’s not often reported as one of the more common symptoms, which includes fever, chills, shortness of breath, cough, and body aches.

Dr Shruti Agnihotri, a neurologist at the University of Alabama at Birmingham, told ABC 33/40 that brain fog is often associated with severe headaches and memory loss.

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

Brain fog can look like a concussion, she said.

  • “Patients often describe difficulty in paying attention, concentrating, not feeling well, not as alert as they have been elsewhere. We sometimes see these symptoms in many other conditions, after a concussion, and we also see them after various other infections, ”Agnihotri told ABC 33/40.

The symptom has now appeared with the omicron variant and is another clue as to the impact of the omicron variant on people moving forward.
