Several Covid-19 patients have complained of brain fog, a medical condition that impacts mental ability to do routine work.

Brain fog is being intensely debated around the globe as a post-Covid-19 symptom among patients who have recovered from the SARS-CoV-2 coronavirus. Brain fog is a medical condition when a patient complains about troubling cognitive symptoms.

Confusion, delirium, difficulty in concentration, dizziness, problems in grasping routine conversations, and memory loss are among a set of complaints that several recovered Covid-19 patients have made after they were declared cured of the novel illness. The scientists have warned about this phenomenon for several months.

A new study conducted by the US-based Indiana University School of Medicine covering nearly 4,000 Covid-19 survivors has found that more than 50 per cent of the people had one or the other form of brain fog, which medically is a collective term for a list of over 100 physical neurological and psychological symptoms that make it difficult for a person to carry on day-to-day routine work.

A fairly large number of Covid-19 survivors have found it difficult to function at their workplace as they did earlier. Healthcare workers have been reported to face difficulties in recalling what a patient complained about only a minute ago. Some Covid-19 survivors have complained that they felt like they were suffering from dementia.

The Indiana University's survey is not the first to highlight the functional disability of brain due to Covid-19. In August, France's University of Paris had found that around 34 per cent recovered Covid-19 patients complained of memory loss.

Another 28 per cent said they had difficulty in concentrating on the work they did and around 31 per cent reported sleep disorder. The French study said these symptoms persisted for up to four months after recovery from Covid-19. However, that study was conducted on a smaller group of 120 Covid-19 survivors.

Another study found that though Covid-19 is considered primarily a respiratory illness, its causative agent the SARS-CoV-2 coronavirus attacks the brain. It was highlighted by experts from the John Hopkins University.

Researchers have found indications that the novel coronavirus infects the brain to make copies of the brain cells to "steal" away oxygen and starve the brain cells to death. This leaves the patients with headache, confusion and delirium.
