Scientists may have found a “unifying theory” of chronic fatigue
Scientists found that five seemingly unrelated conditions, including long Covid, ME/CFS, and PTSD, may disrupt many of the same biological networks involved in immunity, metabolism, and cellular energy. The findings could help explain their shared symptoms and may open the door t
