According to a March 2021 review of research published in the journal Frontiers in Psychology, researchers at U.K.-based Oxford Brookes University found that there’s one symptom that affects the vast majority of COVID patients: post-traumatic stress disorder (PTSD). Citing a study published in the March 2020 volume of Psychological Medicine, the article’s authors noted that up to 96 percent of medically stable study subjects with a COVID diagnosis experienced PTSD. “Understanding the neuropsychiatric and cognitive consequences of COVID-19 is important as millions of people have been affected by the virus, and many cases go undetected. These conditions affect people’s capacity to work effectively, drive, manage finances, make informed decisions and participate in daily family activities,” explained Sanjay Kumar, PhD, Senior Lecturer in Psychology at Oxford Brookes University, and the new study’s lead author, in a statement.
