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.
Most of these symptoms can be successfully managed through adjustments in the dosage or schedule of medication. Approximately 15% to 30% of children experience motor tics, most of which are transient, while on stimulant medications. In addition, approximately half of children with Tourette syndrome have ADHD.
