Some explanations name inflammation, poor sleep and emotional distress as causes. A different idea from a researcher is that repeated itch signals from damaged skin change brain circuits directly. If so, those brain changes could affect how people sense things, feel emotions and control mood. More studies are needed to test these ideas before doctors change treatments.
