Although fibromyalgia is associated with changes in brain function and neural pathways, researchers saw no differences in responses to placebo pain relief between fibromyalgia patients and healthy volunteers in a new study. This research, funded by the National Center for Complementary and Integrative Health (NCCIH), was recently published in the journal Pain.
Fibromyalgia is a common disorder that involves widespread pain, tenderness, fatigue, and other symptoms. People with fibromyalgia and other individuals with chronic pain have anatomical, functional, and neurochemical changes in brain regions and neural pathways involved in placebo analgesia (pain relief in response to a “medicine” that contains no active pain-relieving ingredients). In this study, researchers from NCCIH, University of Colorado, University of Maryland, McGill University, and Balgrist University Hospital/University of Zurich investigated whether fibromyalgia patients would differ from healthy control subjects in their behavioral and neural responses to placebo pain relief.
