8. " MS diagnosis" is the key phrase here. Lots of subclinical disease is diagnosed
now thanks to MRI. Disease that never would have been suspected in the pre-MRI days. People whose only symptoms are fatigue, memory problems or headaches (not the nerve damage and stroke that were once required to make the diagnosis of MS), who get MRIs to rule out brain tumor and in whom MS is never even suspected until the report comes back as something like "can not rule out MS"---at which point the patient and doctor seize the diagnosis. Which raises the question, do they really have MS? Or some other disorder associated with their obesity such as sleep apnea which can also cause fatigue, memory problems and headaches.
