Introduction

Attention-Deficit/Hyperactivity Disorder (ADHD) is a behavior disorder characterized by a pattern of attention problems, hyperactive behaviors, and/or impulsive behaviors that are more frequent and severe than what is typical for a child/adult of the same age. ADHD is one of the most commonly diagnosed childhood behavior disorders. Approximately 7.8% of children ages 4-17 are diagnosed with this disorder.

Boys are more likely to be diagnosed with ADHD than girls, with approximately 11% of boys ages 4-17 having the diagnosis, but only 4.4% of same-aged girls. Although symptoms of ADHD can be present in children as young as 2-3 years old, it is most commonly diagnosed in the elementary school years when the demands of school expose the problem. The most common age of diagnosis is seven years old.

In most cases, symptoms of ADHD continue through early adolescence, but begin to subside in late adolescence and adulthood. However, some individuals continue to experience mild to full-blown symptoms of ADHD well into adulthood. Approximately 4.1% of adults ages 18-44 have a diagnosis of ADHD.

The following is a list of signs associated with ADHD (American Psychological Association, 1994). Keep in mind that ADHD is not an "on-again, off-again" style of behavior. A good rule of thumb is that a person must display several of these behaviors for 6 months or more before a diagnosis of ADHD is considered.
