Two million more children in the United States have been diagnosed with attention-deficit/hyperactivity disorder (ADHD) and one million more U.S. children were taking medication for ADHD over an 8 year period (2003-2004 to 2011-2012), according to a new study led by CDC. According to CDC scientists, children are commonly being diagnosed at a young age. Half of children diagnosed with ADHD are diagnosed by 6 years of age. Children with more severe ADHD tend to be diagnosed earlier, about half of them by the age of 4, based on reports by parents.
ADHD is one of the most common chronic conditions of childhood. It often persists into adulthood. Children with ADHD may have trouble paying attention and/or controlling impulsive behaviors. Effective treatments for ADHD include medication, mental health treatment, or a combination of the two. When children diagnosed with ADHD receive proper treatment, they have the best chance of thriving at home, doing well at school, and making and keeping friends.
- In 2011-2012, 11 percent of U.S. children 4-17 years of age had been diagnosed with ADHD and 6.1 percent of U.S. children 4-17 years of age were taking medication for ADHD. Of the children with current ADHD, 69 percent were taking medication for ADHD treatment.
- States vary widely in terms of the percentage of their child population diagnosed and treated with medication for ADHD. The percentage of children with a history of an ADHD diagnosis ranges from 15 percent in Arkansas and Kentucky to 4 percent in Nevada.
- Medication treatment for ADHD is most common among children reported by their parents as having more severe ADHD.
- Nearly one in five high school boys and one in 11 high school girls in the United States were reported by their parents as having been diagnosed with ADHD by a healthcare provider.
