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.
Stimulants are the best-known and most widely used ADHD medications. Between 70-80 percent of children with ADHD have fewer ADHD symptoms when they take these fast-acting medications. Nonstimulants were approved for treating ADHD in 2003. Nonstimulants do not work as quickly as stimulants, but they can last up to 24 hours.
