Summary
This study tests whether hyperbaric oxygen therapy (HBOT) can help relieve brain fog and other lingering symptoms in people with Long COVID. HBOT delivers high levels of oxygen to the body, which may reduce inflammation and improve blood flow. Researchers will enroll 120 adults who have had COVID-19 and still experience cognitive problems like slow thinking or memory issues.
