It is a common, relapsing disorder that causes rashes and itching, at times intense, and usually improves later in childhood. Many people, however, continue to be affected to some degree throughout their lives.
Some studies show that breastfed children have a lower incidence of atopic dermatitis.
Causes Genetics play an important role in the occurrence of atopic dermatitis, although the exact mechanism is unknown. When both parents have a history of atopic dermatitis, there is an 80 percent chance that their children will have it. Families with a history of asthma and allergies also experience a higher incidence rate. Atopic skin often is dry and sensitive, and intense itching is a cardinal feature. The constant rubbing and scratching this provokes sets in motion an itch-scratch cycle that is difficult to control.
