What Causes Atopic Dermatitis?
Atopic dermatitis, also called atopic eczemaor just eczema, is the name given to a stubborn, itchy rash that occurs in certain persons with sensitive or irritable skin. The cause of eczema is not known. It's the result of a built-in defect of the skin that tends to run in families. Eczema is not contagious and is not related to your general health. Atopic dermatitis is also called constitutional eczema; this name emphasizes the built-in aspect. Persons with eczema have skin that is dry and easily irritated by soap, detergents, and rough woolen clothing. Very hot or very cold weather often aggravates eczema. While certain allergies may worsen eczema, they don't cause it.
