Attention-Deficit/Hyperactivity Disorder: ADHD Basics

Attention deficit hyperactivity disorder (ADHD) is a developmental and behavioral disorder that affects 3% to 5% of all school-age children.

Although the condition usually manifests in childhood, it can persist into adulthood, causing difficulties at home, at school and at work if not recognized and treated.

In fact, experts now estimate that ADHD affects about 60% of adults who had ADHD in childhood.

What Are the Symptoms?

The symptoms of ADHD include inattention, impulsiveness and hyperactivity that are inappropriate for a person's age level.

Children who have ADHD often:

• Are easily distracted by sights and sounds in their environment.
• Are unable to concentrate for long periods of time on low stimulation tasks (homework vs. video games).
• Are restless and impulsive.
• Have a tendency to daydream.
• Are slow to complete tasks.

Adults who have ADHD often:

• Miss work deadlines.
• Miss appointments.
• Appear hectic and disorganized.
• Have significant problems prioritizing.

Symptoms of ADHD in adults and children vary by individual and range from mild to severe.

What Causes ADHD?

The exact cause of ADHD isn't known.

Experts do know that there are changes in the brains of people with the condition. It is not caused by home or school situations or by poor parenting.

How Is ADHD Diagnosed?

There is no single test used to diagnose ADHD. It is diagnosed after a child has shown some or all of symptoms of ADHD on a regular basis for more than 6 months.

The diagnosis of ADHD involves the gathering of information from several sources, including school, caregivers, and parents. The health care provider will consider how a child's behavior compares with that of other children the same age.

The health care provider will also do a physical exam to look for any medical problems that may affect a child's behavior.

ADHD in adults is diagnosed using a similar process.

How Is ADHD Treated?

Although there is no cure for ADHD, treatment can help control symptoms. There are several types of treatments available.

Stimulants

Stimulant medications (or psychostimulants) have been used to successfully treat ADHD symptoms for many years. Stimulants are used to treat both moderate and severe ADHD in adults and children over age 6, with the exception of Adderal, Dexedrine, and Dextrostat, which can be safely used in children as young as age 3.

Stimulants used to treat ADHD include:

• Adderall, Adderall XR
• Concerta
• Dexedrine, Dexedrine Spansule Capsules, Dextrostat
• Focalin, Focalin XR
• Metadate CD, Metadate ER
• Methylin, Methylin ER
• Ritalin, Ritalin LA, Ritalin SR
• Vyvanse

Nonstimulant Therapy

In November 2003, the FDA approved Strattera as the first nonstimulant treatment for ADHD. It is the first treatment approved to control ADHD symptoms in children, adolescents, and adults. In September 2005, the FDA issued a warning about the increased risk of suicidal thinking in children and adolescents taking Strattera. Doctors are advised to watch for this behavior and alter medications as needed.
