Brain Processing of Contagious Itch in Patients with Atopic Dermatitis
Several studies show that itch and scratching cannot only be induced by pruritogens like histamine or cowhage, but also by the presentation of certain (audio-) visual stimuli like pictures on crawling insects or videos showing other people scratching. This phenomenon is coined "Contagious itch" (CI). Due to the fact that CI is more profound in patients with the chronic itchy skin disease atopic...
متن کاملEffect of itch, scratching and mental stress on autonomic nervous system function in atopic dermatitis.
Atopic dermatitis is a stress-responsive disorder that involves the autonomic nervous system. The current study used heart rate variability to examine the effect of itch, scratching and mental stress in atopic patients with moderate to severe disease. Twenty-one patients with active disease and 24 healthy volunteers participated in the study. Heart rate variability measurements were taken at 5 ...
متن کاملItch in atopic dermatitis - pathophysiology and treatment.
Pruritus is an essential feature of atopic dermatitis with a high impact on the quality of life. Although the pathophysiology of atopic dermatitis itch is not fully understood, recent studies have demonstrated that a variety of mechanisms contribute to the induction and maintenance of the symptom. For example, an increased number of cutaneous nerve fibers and neuropeptides were identified in at...
متن کاملThe imagined itch: brain circuitry supporting nocebo-induced itch in atopic dermatitis patients.
BACKGROUND Psychological factors are known to significantly modulate itch in patients suffering from chronic itch. Itch is also highly susceptible to both placebo and nocebo (negative placebo) effects. Brain activity likely supports nocebo-induced itch, but is currently unknown. METHODS We collected functional MRI (fMRI) data from atopic dermatitis (AD) patients, in a within-subject design, a...
متن کاملThe Missing Link between Itch and Inflammation in Atopic Dermatitis
Atopic dermatitis is a common skin disease with high morbidity and is associated with severe itch and chronic skin inflammation. In this issue of Cell, Wilson et al. demonstrate that epithelial cells communicate directly with cutaneous sensory neurons via a cytokine to induce itch.
