More than 5 million U.S. children, or 9.5 percent, have been diagnosed with ADHD as of 2007, according to the U.S. Centers for Disease Control and Prevention. Kids with the condition may act more impulsively, and have difficulty paying attention and controlling their behavior.
The data from a national sample of children with special health care needs, ages 4-17 years, collected in 2009-10, showed that most children with ADHD received either medication treatment or behavioral therapy; however, many were not receiving treatment as described in the best practice guidelines from 2011. Approximately 11% of children 4-17 years of age (6.4 million) have been diagnosed with ADHD as of 2011. 2  The percentage of children with an ADHD diagnosis continues to increase, from 7.8% in 2003 to 9.5% in 2007 and to 11.0% in 2011.
