People who have contracted Covid-19 are more at risk of having brain damage a year later than people who have never been infected with the coronavirus, American researchers reported on Thursday, September 22. A study, published in the scientific journal Nature, evaluated over a year more than 40 brain injuries reported in the medical records of millions of American veterans. More than 7% of people who contracted Covid-19 had brain and neurological damage compared to veterans who had never been infected with the coronavirus, notes Archyde.com. This means that regarding 6.6 million Americans have developed brain disorders following infection with Sars-CoV-2, the virus responsible for Covid-19, the team that conducted the study estimated. Memory problems are the most common and people who have contracted the coronavirus have a 77% risk of developing them compared to the general population. People who have been infected with Covid-19 are also more likely to suffer from a stroke (50%), epileptic seizures (80%), suffer from migraines (42%), mental health problems such as depression or anxiety (35%) and to develop neurological symptoms, such as tremors, than the rest of the population.
