Researchers pursue ‘hidden pathology’ to explain fatigue in multiple sclerosis

In a study published in Neurology Neuroimmunology & Neuroinflammation, investigators from Brigham and Women’s Hospital used positron emission technology (PET) imaging to look for brain’s immune cells that may become erroneously activated in MS, leading to fatigue. The team describes a potential link to brain inflammation that may help explain the connection between MS and fatigue.
