Close to 9% of children aged 4 to 17 years have received a diagnosis of ADHD. It's a behavioral disorder marked by impulsiveness, hyperactivity, and inattention.
Stimulants such as Adderall, Concerta, Dexedrine, and Ritalin are often the first line of therapy. Treatment also involves behavioral changes, such as keeping set schedules and routines.
Researchers tracked how many children and teens under age 19 were taking stimulants from 1996 to 2008.
Overall, 3.5% or an estimated 2.8 million children received a prescription for a stimulant medication to treat ADHD in 2008. By contrast, 2.9% of kids were taking stimulants in 1996. Stimulant use increased at an average yearly rate of 3.4% from 1996 to 2008.
This is markedly slower than the 17% growth rate seen from 1987 to 1996, the researchers report in the American Journal of Psychiatry.
There are several non-stimulant medications approved to treat ADHD in children and teens. "Stimulants remain the main treatment for ADHD," says researcher Benedetto Vitiello, MD, of the National Institute of Mental Health in Bethesda, Md.
Rates of Stimulant Use
The use of stimulants remains highest among children aged 6-12, but teens aged 13 to 18 may be catching up. They had the fastest growth rate for prescribed use of stimulants in the new study, 2.3% in 1996 to 4.9% in 2008.
Other key findings about stimulant use among children with ADHD from 1996 to 2008 include:
- Prescription stimulant use among preschoolers remained very low at 0.1% from 2004 to 2008.
- Boys continued to be three times more likely than girls to be prescribed a stimulant.
- Stimulant use is still higher among white children than African-American or Hispanic children, but the gap may be narrowing.
- Stimulant prescription rates were substantially lower in Western states compared to other U.S. regions.
Side Effects of ADHD Drugs
Stimulants do have side effects such as decreased appetite and sleeplessness. There are some studies showing that they may also have some heart-related side effects.
