Half of children with ADHD are diagnosed by age six.

However, children with more severe ADHD tend to be diagnosed earlier, about half of them by the age of 4.

*These reports are from a survey of parents of children 4-17 years of age.

If you have concerns about your child and ADHD, complete a checklist about their behavior and bring it to your child’s healthcare provider: www.cdc.gov/adhd
