Can a child grow out of adhd?

30-65% chance: Longitudinal studies lasting more than 20 years have shown that adhd resolves in about 35% of children. But if stimulant treatement is started before 7 yo, the risk of persisting into adulthood drops to 35%. In other words, if treatment is started early, instead of a 65% chance of still having adhd in adulthood, the risk drops to 35%. Good reason to treat early.

Kind of/partially: In my experience, children/adults can grow out of the hyperactivity by learning to control it as their brain matures. The attention/focus problems may improve, but i'm not sure they ever go away. The studies that address this have focused mainly on the symptoms of hyperactivity, since they are easier to measure. Teens with a history of "resolved" adhd still have 2-4 times the risk of car wrecks.

Maybeeee!: Some kids seem to do better at adolescence, some adolescents at adulthood.The important question is whether the child, adolescent, or adult has learn to control the behavior so it is no longer causing significant impairement.

Yes: About 50% of children with ADHD will outgrow their symptoms by the end of high School.
