ADHD is the diagnosis for an array of difficulties, but the common thread that unites them is difficulty in regulating attention—paying the right amount of attention for the appropriate amount of time. In addition, symptoms typically include distractibility, and often impulsivity and/or hyperactivity.
Attentional issues are among the most common disorders affecting children. Recent studies show that approximately 11% of U.S. children ages 4 to 17 have an ADHD diagnosis. On average children are diagnosed at age 7, though research suggests that severe cases are often diagnosed earlier, while girls are frequently not diagnosed until puberty.
Boys are three times more likely than girls to be screened for ADHD. Girls with ADHD may not act out in the classroom as boys often do, and therefore are not referred for evaluation as often as their male peers. Girls with ADHD may be quiet and cooperative, hoping not to be noticed. They may also present with physical complaints, anxiety, dreaminess or extreme disorganization.

Science has yet to determine what causes ADHD, however there is growing evidence to suggest that genetics plays a key role. Other potential risk factors include environmental exposures (e.g. cigarette smoke and alcohol in utero, and lead in childhood), brain injury, premature delivery, and low-birth weight.
Like other learning disabilities, ADHD cannot be cured, however many of the problematic symptoms can be treated so that children (and adults) can lead productive lives. The most successful treatments involve a combination of medication, behavioral therapy, and educational interventions.
Signs & Symptoms: ADHD Subtypes
Not all children with ADHD display the same behaviors. There are three subtypes of ADHD. If your child falls into one or more of these categories consider having him or her evaluated for ADHD.
- Inattentive (sometimes called ADD) does not include hyperactivity. A child may appear “spacey” or “not all there,” and often fails to pick up on some part of the information provided whether presented verbally or in writing.
- Hyperactive includes many of the stereotypical behaviors associated with ADHD such as constant fidgeting, shifting or moving, difficulty staying seated in class, and the inability to stay focused on one task.
- Impulsive is characterized by a tendency to act before thinking about consequences. It can impact academics (students jump to the wrong conclusion), teachers’ perceptions (students are thought to be “talking back”), and the likelihood of engaging in physically and socially risky behaviors.
Most children have combined hyperactive-impulsive and inattentive ADHD.
