Abstract
A newly-identified mechanism of chronic pain is "nociplastic pain, " which can be triggered by central sensitization, dysfunction of the mesolimbic dopamine system, and/or descending pain inhibiting pathway. This is a "third type of brain-generated pain" caused by unpleasant emotions, with or without peripheral injury, and is classified as chronic primary pain (MG30.0) in ICD-11. Fibromyalgia is a typical example, but temporomandibular disorders (TMD) are also included in this category, specifically burning mouth syndrome (BMS) and persistent idiopathic dentoalveolar pain (PIDAP). Psychosocial factors are often involved in patients with chronic pain, in which case an accurate assessment of these factors and a corresponding cognitive-behavioral approach are required. I introduced an original psychosocial flags system, which was developed by members of the Policy Research Project of the Ministry of Health, Labour and Welfare on chronic pain. The "psychosocial flags framework" originated in the U.K. for the multidisciplinary treatment of musculoskeletal pain, and is recommended in neck and back pain guidelines in Europe. I focused on the yellow flags (i.e., psychosocial factors used to screen for cognitive-behavioral therapy), which will be an appropriate operation system for motivated therapists.
