Is Eczema the Same as AD?

Eczema is a general term for any type of dermatitis or “inflammation of the skin.”

Atopic dermatitis (AD) is the most severe and chronic (long-lasting) kind of eczema. Although the term eczema is often used for atopic dermatitis, there are several other skin diseases that are eczemas as well. A partial list of eczemas includes: atopic dermatitis, nummular eczema, dyshidrotic eczema, seborrheic dermatitis, irritant contact dermatitis, allergic contact dermatitis. All types of eczema cause itching and redness and some will blister, weep or peel.
