Most people with chronic pain wish that there was some way that others could see their pain. Researchers have come a step closer to this goal by identifying the brain activity patterns related to chronic pain. MRI scans of patients with fibromyalgia (FM) showed their Neurological Pain Signature. It was possible to distinguish FM patients from healthy control. Researchers believe that these findings will contribute to the understanding of what areas of the brain are different in FM compared to healthy people and thus may be useful for the diagnosis and treatment of FM.
