摘要
Chronic pain syndrome is a complex disorder that includes not only the presence of spontaneous pain and exaggerated responses to painful and nonpainful stimuli but also the development of a negative affective, motivational, and cognitive state and the persistent desire to eliminate pain. Recent evidence indicates that chronic pain shares basic mechanisms with reward-based learning and drug addiction 1-3 and that the transition from acute to chronic pain reflects functional reorganization of this reward/motivational circuitry. 4 © 2016 American Academy of Neurology.
