Itch and pain.
The discovery of a specialized neuronal pathway for itch has markedly improved our understanding of itch processing under physiological conditions. However, the complex interactions of pain and itch are only partly understood. This review focuses on the neurophysiological mechanisms involved in clinical and experimental itch conditions. There is emerging evidence that similar patterns of periph...
متن کاملItch and pain.
Decades of pain research have succeeded in elucidating complex mechanisms of acute activation and chronic sensitization of nociceptors leading to pain. In contrast, itch conditions have received less attention and even basic mechanisms for the induction of itch are still unclear. In this review we describe itch-specific pathways, but also evidence for a modified pattern theory of pruritus offer...
متن کاملA counterpart to pain: itch
Pain is not the only defense mechanism that alerts us to a physical hazard — the other is itch, an unpleasant sensation that is distinct from pain because it provokes the desire to scratch. Although pain and itch feel different, these two sensations share many qualities. Both are aversive sensations that evolved to protect us. Moreover, both can become pathological, developing into chronic debi...
متن کاملMany parallels between itch and pain research.
Acute itch is a commonplace sensation elicited by insect bites and certain plants, and normally serves as a protective warning signal. However, chronic itch is a frequent symptom of dermatologic conditions and a variety of systemic diseases (for recent review, see LaMotte et al., 2014). Current treatments for chronic itch are poor, leading to suffering and diminished quality of life. The situat...
متن کاملStructural modeling of pain perception in people with chronic pain syndrome based on behavioral inhibition system: mediated by pain catastrophe and perceived social support
Abstract Introduction: Chronic pain, especially skeletal muscle pain, is very common and can affect the quality of life and health of the patient and families; Therefore, the present study was conducted to investigate the relationship between behavioral inhibition system and pain perception by mediating role of pain catastrophe and perceived social support in people with chronic pain syndrome....
