Atopic dermatitis affects about 20% of people at some point in their lives.[1][4] It is more common in younger children.[2] Males and females are equally affected.[1] Many people outgrow the condition.[2] Atopic dermatitis is sometimes called eczema, a term that also refers to a larger group of skin conditions.[1] Other names include "infantile eczema", "flexural eczema", "prurigo Besnier", "allergic eczema", and "neurodermatitis".[5]
