This review examines ME/CFS as a real medical condition affecting the nervous system, immune system, and stress response. While researchers have found many different abnormalities in ME/CFS patients—including viral reactivation, immune problems, and chemical imbalances in the brain—no single cause has been identified in everyone with the condition. The authors suggest that ME/CFS likely results from a combination of genetic factors and life stress that disrupts how the body's immune and hormone systems work together.
