A team of researchers has found that sometimes itching, like yawning, can be contagious.
Researchers found those with AD had higher itch intensity and scratched more frequently while watching the videos of other subjects scratching. Of interest, said Yosipovitch, is that the visually induced itch had a scattered, wide body distribution of scratching. "This shows that the power of the brain is pretty extreme," said Papoiu. "This speaks to a core of our being, to being particularly vulnerable to suggestions of itch, which can easily trigger a response from our central nervous system." The new findings appear online in The British Journal of Dermatology. ANI
