Atopic dermatitis (also known as AD) is the most common type of eczema. In fact, 17.8 million Americans have AD — which often appears as a red, itchy rash normally on the cheeks, arms and legs.
Atopic dermatitis exists with two other allergic conditions: asthma and hay fever (allergic rhinitis). People who have asthma and/or hay fever or who have family members who do, are more likely to develop AD.
AD typically begins in childhood, usually in the first six months of a baby’s life. Even though it’s the most common form of eczema, it’s also the most severe and long-lasting. When you or your child have AD, it may improve at times, but at others it may get worse or flare up. Often, AD disappears as a child grows older, though some children will continue to experience atopic dermatitis into adulthood.
We don’t know the exact cause of atopic dermatitis. Researchers do know that a combination of genetics and environmental factors are involved. When something from outside the body triggers the immune system, the skin cells don’t behave like they should, causing the skin to flare up.
We also know that AD runs in families, but we don’t know the exact way it is passed from parents to children. If one parent has AD, asthma, or hay fever, there’s about a 50% chance that their child will have at least one of these diseases. If both parents have one or more of these conditions, the chances are much greater that their child will, too.
An estimated 10% of all people worldwide are affected by atopic dermatitis at some point in their life. The condition seems to be more common in urban areas and developed countries and affects men and women of all races equally. Either way, AD is not contagious. You or your child cannot “catch” it from another person, or give it to someone else.
Atopic dermatitis is considered a more severe type of eczema. People with AD may experience a number of different sensitivities for the rest of their lives:
There are other types of eczema that cause itching and redness, but some will also cause your skin to blister, “weep,” or peel.

Unlike other kinds of eczema, atopic dermatitis does not usually go away in a few days or weeks. It might get better or worse but the AD symptoms typically return.
AD is very itchy. You or your child’s skin can become damaged from repeated scratching or rubbing. AD normally appears on the cheeks, arms and legs, but can be anywhere on the body.
