New research from the University of Copenhagen reveals that severe Covid-19 patients experience impaired brain function similar to individuals hospitalized for pneumonia. The study, published in JAMA Network Open, examines the long-term effects of COVID-19 on brain health. The research involved 345 participants, including Covid-19 patients, pneumonia patients, and healthy controls. Results show that COVID-19 patients exhibited worse cognitive, neurological, and psychiatric effects compared to healthy individuals. However, the deficits in brain function were not significantly different from those in patients hospitalized for other health problems.
