Allodynia is defined as pain in response to a nonnociceptive stimulus (Loeser and Treede, 2008). This can happen commonly with burns and many other injuries and conditions. Our results provide evidence for stress-induced allodynia/hyperalgesia in humans for the first time and suggest differential underlying mechanisms determining response to stressors in healthy subjects and patients suffering from chronic pain. 9 mainly expressed in small fiber sensory neurons have been associated with neuropathic disorders; however, suitable medications have not been fully investigated. . Personally, if I am subjected to loud noises, bright lights, or overwhelming smells for an extended period the result will be a migraine. The official IASP definition of allodynia at the time of this article is "pain due to a stimulus that does not normally provoke pain. “Opioid exposure causes changes in the central nervous system, which can also lead to an intensification of other sensations of pain, including but not limited to allodynia,”. The discovery that tactile allodynia is primarily or exclusively signalled by low-threshold mechanoreceptive afferents overturns the classical dogma that all pain is due to Aδ and C nociceptors. Everything You Should Know About Allodynia. The bottom trace shows the APs initiated by 3 successive depolarizing pulses in Gly neuron.

(2011) that allows comparisons with responses of lumbar dorsal horn neurons to pruritic and noxious stimuli. Lipton’s has shown that allodynia is a distinct, recurring component in the progression of a migraine attack, something that is only recently widely recognized. In humans, tissue injury and depression can both cause pain hypersensitivity, but whether this involves distinct circuits remains unknown. In fact, allodynia occurs in 15 to 50 percent of patients with. 5. It severely debilitates the quality of life. Complex Regional Pain Syndrome, also known as reflex sympathetic dystrophy, is an idiopathic condition caused by an aberrant inflammatory response that leads to sustained sympathetic activity in a perpetuated reflex arc. Na+,K+-ATPase (NKA) is required to generate the resting membrane potential in neurons. Mechanical allodynia (other pain) is a painful sensation caused by innocuous stimuli like light touch. Unlike inflammatory hyperalgesia that has a protective role, allodynia has no obvious biological utility.
