What Is ADHD?

Lisa's son Jack had always been a handful. Even as a preschooler, he would tear through the house like a tornado, shouting, roughhousing, and climbing the furniture. No toy or activity ever held his interest for more than a few minutes and he would often dart off without warning, seemingly unaware of the dangers of a busy street or a crowded mall.

It was exhausting to parent Jack, but Lisa hadn't been too concerned back then. Boys will be boys, she figured. But at age 8, he was no easier to handle. It was a struggle to get Jack to settle down long enough to complete even the simplest tasks, from chores to homework. When his teacher's comments about his inattention and disruptive behavior in class became too frequent to ignore, Lisa took Jack to the doctor, who recommended an evaluation for attention deficit hyperactivity disorder (ADHD).

ADHD is a common behavioral disorder that affects an estimated 8% to 10% of school-age children. Boys are about three times more likely than girls to be diagnosed with it, though it's not yet understood why.

Kids with ADHD act without thinking, are hyperactive, and have trouble focusing. They may understand what's expected of them but have trouble following through because they can't sit still, pay attention, or attend to details.

Of course, all kids (especially younger ones) act this way at times, particularly when they're anxious or excited. But the difference with ADHD is that symptoms are present over a longer period of time and occur in different settings. They impair a child's ability to function socially, academically, and at home.

The good news is that with proper treatment, kids with ADHD can learn to successfully live with and manage their symptoms.

Symptoms

ADHD used to be known as attention deficit disorder, or ADD. In 1994, it was renamed ADHD and broken down into three subtypes, each with its own pattern of behaviors:

1. an inattentive type, with signs that include:

• inability to pay attention to details or a tendency to make careless errors in schoolwork or other activities
• difficulty with sustained attention in tasks or play activities
• apparent listening problems
• difficulty following instructions
• problems with organization
• avoidance or dislike of tasks that require mental effort
• tendency to lose things like toys, notebooks, or homework
• distractibility
• forgetfulness in daily activities

2. a hyperactive-impulsive type, with signs that include:

• fidgeting or squirming
• difficulty remaining seated
• excessive running or climbing
• difficulty playing quietly
• always seeming to be "on the go"
• excessive talking
• blurting out answers before hearing the full question
• difficulty waiting for a turn or in line
• problems with interrupting or intruding

3. a combined type, which involves a combination of the other two types and is the most common

Although it can be challenging to raise kids with ADHD, it's important to remember they aren't "bad," "acting out," or being difficult on purpose. And they have difficulty controlling their behavior without medication or behavioral therapy.

Diagnosis

Because there's no test that can determine the presence of ADHD, a diagnosis depends on a complete evaluation. Many children and adolescents diagnosed with ADHD are evaluated and treated by primary care doctors including pediatricians and family practitioners, but your child may also be referred to one of several different specialists (psychiatrists, psychologists, neurologists) especially when the diagnosis is in doubt, or if there are other concerns, such as Tourette syndrome, a learning disability, anxiety, or depression.

To be considered for a diagnosis of ADHD:

• a child must display behaviors from one of the three subtypes before age 7
• these behaviors must be more severe than in other kids the same age
• the behaviors must last for at least 6 months
• the behaviors must occur in and negatively affect at least two areas of a child's life (such as school, home, day-care settings, or friendships)

The behaviors must also not only be linked to stress at home. Kids who have experienced a divorce, a move, an illness, a change in school, or other significant life event may suddenly begin to act out or become forgetful. To avoid a misdiagnosis, it's important to consider whether these factors played a role in the onset of symptoms
