The term "psychogenic pain" had begun to fall out of relevance in the scientific community due to its implication that the pain is entirely psychological in origin and thus not "real". The change in preferred nomenclature can be traced to 1994 when the DSM-IV removed the term in favor of the more holistic "
pain disorder" section. Nociplastic pain is defined as chronic pain that cannot be classified as
nociceptive (pain caused by the activation of nociceptors) or
neuropathic (pain caused by damage to the nervous system). Nociplastic pain is functionally defined in one article as "pain arising from the altered function of pain-related sensory pathways in the
periphery and
CNS (Central Nervous System)," and, unlike psychogenic pain, can be diagnosed in conjunction with other types of pain. ==See also==
