Review[Pathophysiology of chronic pain. Classification of three subtypes of pain].
Pain is a physiological sensation which aim is to alert for an upcoming danger that may threaten the individual. This system includes peripheral nociceptors that initiate the nociceptive message. Then, the information is conveyed to the brain through the spinothalamic tract that projects to the thalamus, insula, SII and other areas. ⋯ This is the neuropathic pain. Case 3: between the two former cases, there is no evidence for a lesion in the nociceptive system, and there are no evidences for lesion at the peripheral level, but there are evidences of dysregulation(s). These are the cases of dysfunctional pain.

The major development of experimental and clinical pain research over the last two decades should result in the development of new treatment strategies. In the future, the management of chronic pain should rely both on new molecules targetting specific pathophysiological mechanisms and new non pharmacological approaches, such as non invasive transcranial magnetic stimulation, acting on endogenous pain modulatory systems. The variety of new treatment options should allow a more efficacious management of chronic pain, taylored to each patient's profile.
