Neuroimaging of Central Sensitivity Syndromes: Key Insights from the Scientific Literature.
Walitt, Brian, Ceko, Marta, Gracely, John L et al.·Current rheumatology reviews·2016
This review examined brain imaging studies of ME/CFS and similar conditions to understand what happens in the nervous system. Researchers found that people with these conditions show increased sensitivity to pain and other sensations, suggesting these are real physical conditions—not imaginary or feigned. However, brain imaging hasn't yet revealed a single clear pattern or 'fingerprint' that all these conditions share, and we still don't know if this sensory sensitivity causes the disease or is a result of it.
