What is Attention Deficit Hyperactivity Disorder?

ADHD is characterized by developmentally inappropriate levels of inattention, impulsivity, and/or overactivity. People with ADHD often have difficulty following instructions, keeping things organized, not interrupting others, acting without thinking, talking excessively, or feeling fidgety or restless. Some people have problems with all three types of symptoms, while other people have problems primarily with inattention or with impulsivity and overactivity.

ADHD usually begins in childhood while many individuals continue to show ADHD symptoms into adulthood. ADHD occurs in 3 to 5% of elementary-school aged children and is more common in males than females.

In addition to the problems with inattention, impulsivity, and overactivity, individuals with ADHD often have academic or employment problems and difficulties in social interactions. ADHD often co-occurs with problems such as disruptive behavior (including conduct disorder), learning disabilities, and depression or anxiety.

ADHD appears to have a biological basis, and in some cases, may be an inherited condition. However, the specific cause of the disorder is not known and it is likely that multiple causes or contributing factors exist.

There is no one test for ADHD. Instead, assessment requires gathering information from several sources, using standardized measures, and careful consideration of other possible causes of the behavior. Psychologists are well qualified to conduct such assessments.

What psychological treatments are used to treat ADHD?

The most effective treatment for ADHD has been shown to be a combination of behavior therapy and medication. Behavior therapy is particularly important in addressing social problems in individuals with ADHD and helps to prevent or treat the social and behavior problems that can occur with ADHD. Additionally, behavior therapy alone has been shown to be very effective with many individuals.

Behavior therapy involves several techniques and focuses on establishing clear rules for the individual's behavior and providing frequent feedback in the form of rewards and mild punishments. Behavior therapy also includes modeling, problem-solving, and social skills training. For children, behavior therapy is often conducted both in the classroom and at home and parents and teachers are essential in implementing the therapy.

More information regarding effective treatments for ADHD can be found in a consensus statement on the Diagnosis and Treatment of ADHD developed by the US National Institutes of Health (www.nih.gov) and in the following article: The MTA Cooperative Group (1999).
