Recovered Covid-19 Patients Can Suffer From “Brain Fog” For Months, Even If The Illness Was Mild, Study Says

People who have recovered from the coronavirus may suffer from a cognitive disorder known as “brain fog,” even if they had a mild form of the disease and were not hospitalized, warns a study published this Friday in the JAMA Network Open magazine.

In the framework of the research, the data of 740 outpatient and hospitalized coronavirus patients, with a mean age of 49 years and without a history of dementia, were analyzed. The data collected covers the period from April 2020 to May 2021 from the Mount Sinai Health System hospital network registry in New York.

“In this study, we found a relatively high frequency of cognitive decline several months after the patients contracted covid-19 “, reads the text of the research. Specifically, 24% of the patients showed deficits in memory coding, 23% in the ability to remember, 20% in the ability to process categories, 18% in cognitive processing speed, 16% in the performance of executive functions and 15% in phonemic fluency when speaking.

“The association of COVID-19 with executive functioning raises key questions about long-term patient management. Future studies are needed to identify risk factors and mechanisms underlying cognitive dysfunction, as well as options for rehabilitation.” , the experts explain.

It should be remembered that at the end of July a study was published in The Lancet’s EClinicalMedicine that revealed that SARS-CoV-2 can produce substantial reductions in cognitive ability in patients, especially those who developed a more severe form of the disease.

The researchers determined that those who had had COVID-19 tended to underperform on the intelligence test compared to those who had not contracted the virus. The largest deficits were observed in tasks that required reasoning, planning, and problem solving.
