Attention Deficit Hyperactivity Disorder (ADHD) is the most common neurobehavioral disorder of American children. In 2006, 4.5 million children (about 5 percent of school-age children) in the U.S. were diagnosed with ADHD. Eugene Pediatric Associates sees many families that face the challenge of helping their child cope with ADHD. We look forward to helping you learn more about this disorder, its causes, and treatment options.

What is ADHD?

It is normal for all children to have trouble staying focused at times, especially when they are under the age of 5. Children with ADHD, however, do not grow out of these behaviors. Symptoms continue, or even worsen, as children with ADHD enter their school years, which often results in trouble at school and at home.

There are three types of ADHD: Mostly Hyperactive; Mostly Inattentive and Combined Type.

ADHD is often diagnosed in childhood and lasts into adulthood. The most difficult time for people with ADHD is often early childhood, when they have yet to develop the maturity and special tricks that will help them keep on task as adults.

What causes ADHD?

Scientists still do not know exactly what causes ADHD, and much research is being conducted on this disorder. Some risk factors that have been implicated by research include:

  • Genetics: close relatives of people with ADHD are five times more likely to have ADHD.
  • Brain injury.
  • Premature delivery.
  • Low birth-weight.
  • Prenatal drug and alcohol exposure.
  • Environmental toxins (e.g. lead exposure).
