Do children outgrow ADHD?

Many children do outgrow ADHD. However, the latest data suggest that 50% to 70% of children continue to have some symptoms of ADHD in adolescence, and as many as 50% have persistent ADHD in adulthood. However, even in persistent cases, the number of symptoms decrease during adolescence and usually decrease further in adulthood. The types of symptoms also change. Hyperactivity and impulsivity tend to disappear, although adults with ADHD will often comment on their mental as opposed to physical restlessness. From a biological vantage point, the reduction of symptoms probably reflects brain maturation that continues through adolescence and beyond.
