How stress triggers itch: a preliminary study of the mechanism of stress‐induced pruritus using fMRI

Itch is one of the most prevalent and familiar nociceptions in humans and can result in impaired quality of life. The central processing of itch is known to be important in perceptions of itch and strategies for coping with it, and various triggers have been reported to be associated with patterns of brain activation in pruritus. Stress is known to be an important aggravating factor in itch, but the precise mechanism by which brain activation results in stress‐induced pruritus remains elusive.
