Cause 7. Neurodermatitis: The Itch that Rashes
Neurodermatitis, also known as lichen simplex chronicus, is a type of eczema characterized by a single, intensely itchy patch, usually on the neck, wrist, forearm, thigh, or ankle. It’s often associated with other forms of eczema, as the itch-scratch cycle is a common feature.
The exact cause of neurodermatitis isn’t known, but it appears to be associated with stress and anxiety. The constant scratching thickens and hardens the skin, creating a leathery texture. This scratching can become a habit, often continuing even after the initial itch has been treated.
Breaking the itch-scratch cycle is the main goal in treating neurodermatitis. This can be achieved through a combination of medications, stress management techniques, and behavioral therapy. Topical corticosteroids or calcineurin inhibitors can be used to reduce inflammation and itchiness, while antihistamines can help control itching, especially at night. (7)
