Updated guidelines from the American Academy of Pediatrics (AAP) offer new information on diagnosing and treating Attention-Deficit/Hyperactivity Disorder (ADHD) in younger children and in adolescents.

Emerging evidence makes it possible to diagnose and manage ADHD in children from ages 4 to 18 (the previous AAP guidelines, from 2000 and 2001, covered children ages 6 to 12). The new guidelines describe the special considerations involved in diagnosing and treating preschool children and adolescents. They also include interventions to help children with hyperactive/impulsive behaviors that do not meet the full diagnostic criteria for ADHD.

"Treating children at a young age is important, because when we can identify them earlier and provide appropriate treatment, we can increase their chances of succeeding in school," said Mark Wolraich, MD, FAAP, lead author of the report. "Because of greater awareness about ADHD and better ways of diagnosing and treating this disorder, more children are being helped."

ADHD is the most common neurobehavioral disorder in children, occurring in about 8 percent of children and youth.

The report, "ADHD: Clinical Practice Guidelines for the Diagnosis, Evaluation and Treatment of Children and Adolescents with Attention-Deficit/Hyperactivity Disorder," was released Sunday, October 16, at the AAP National Conference & Exhibition in Boston, and will be published in the November 2011 issue of Pediatrics (published online Oct. 16). Dr. Wolraich discussed the new recommendations during a news briefing on Oct. 15, at the Boston Convention & Exhibition Center.

According to the AAP guidelines, in preschool children (ages 4 and 5) with ADHD, doctors should first try behavioral interventions, such as group or individual parent training in behavior management techniques. Methylphenidate may be considered for preschool children with moderate to severe symptoms who do not see significant improvement after behavior therapy, starting with a lower dose. For elementary school children and adolescents, the AAP recommends both FDA-approved medications and behavior therapy.

"Because ADHD is a chronic condition, it requires a team approach, including the patients, their parents, the pediatrician, therapists, and teachers," Dr. Wolraich said.

In addition to the formal recommendations for assessment, diagnosis and treatment of ADHD, the guidelines provide a single algorithm to guide the clinical process. The AAP is also releasing a newly revised and updated ADHD Toolkit to assist health care providers diagnose and treat ADHD in their patients. To help parents understand the new guidance on ADHD, the AAP has published a detailed and updated consumer resource book entitled "ADHD: What Every Parent Needs to Know." Parent information will also be available at www.healthychildren.org/adhd starting Oct. 16.
