Answer

In 85% of cases, AD occurs in the first year of life; in 95% of cases, it occurs before age 5 years. The incidence of AD is highest in early infancy and childhood. The disease may have periods of complete remission, particularly in adolescence, and may then recur in early adult life.

In the adult population, the rate of AD frequency is 3% or higher, but onset may be delayed until adulthood.
