How Is ADHD Identified and Diagnosed?

Many parents see signs of an attention deficit in toddlers long before the child enters school. For example, as a 3-year-old, Henry's son already displayed some signs of hyperactivity. He seemed to lose interest and dart off even during his favorite TV shows or while playing games. Once, during a game of "catch," he left the game before the ball even reached him!

Like Henry's son, a child may be unable to focus long enough to play a simple game. Or, like Mark, the child may be tearing around out of control. But because children mature at different rates, and are very different in personality, temperament, and energy level, it's useful to get an expert's opinion of whether the behaviors are appropriate for the child's age. Parents can ask their pediatrician, or a child psychologist or psychiatrist to assess whether their toddler has an attention disorder or is just immature, has hyperactivity or is just exuberant.

Seeing a child as "a chip off the old block" or "just like his dad" can blind parents to the need for help. Parents may find it hard to see their child's behavior as a problem when it so closely resembles their own. In fact, like Henry, many parents first recognize their own disorder only when their children are diagnosed.

In many cases, the teacher is the first to recognize that a child is hyperactive or inattentive and may consult with the school psychologist. Because teachers work with many children, they come to know how "average" children behave in learning situations that require attention and self control. However, teachers sometimes fail to notice the needs of children like Lisa who are quiet and cooperative.

Types of Professionals Who Make the Diagnosis

School-age and preschool children are often evaluated by a school psychologist or a team made up of the school psychologist and other specialists. But if the school doesn't believe the student has a problem, or if the family wants another opinion, a family may need to see a specialist in private practice. In such cases, who can the family turn to? What kinds of specialists do they need?

The family can start by talking with the child's pediatrician or their family doctor. Some pediatricians may do the assessment themselves, but more often they refer the family to an appropriate specialist they know and trust. In addition, state and local agencies that serve families and children, as well as some of the volunteer organizations listed in the back of this booklet, can help identify an appropriate specialist.

Knowing the differences in qualifications and services can help the family choose someone who can best meet their needs. Besides school psychologists, there are several types of specialists qualified to diagnose and treat ADHD. Child psychiatrists are doctors who specialize in diagnosing and treating childhood mental and behavioral disorders. A psychiatrist can provide therapy and prescribe any needed medications. Child psychologists are also qualified to diagnose and treat ADHD. They can provide therapy for the child and help the family develop ways to deal with the disorder. But psychologists are not medical doctors and must rely on the child's physician to do medical exams and prescribe medication. Neurologists, doctors who work with disorders of the brain and nervous system, can also diagnose ADHD and prescribe medicines. But unlike psychiatrists and psychologists, neurologists usually do not provide therapy for the emotional aspects of the disorder. Adults who think they may have ADHD can also seek a psychologist, psychiatrist, or neurologist. But at present, not all specialists are skilled in identifying or treating ADHD in adults.

Within each specialty, individual doctors and mental health professionals differ in their experience with ADHD. So in selecting a specialist, it's important to find someone with specific training and experience in diagnosing and treating the disorder.

Steps In Making a Diagnosis

Whatever the specialist's expertise, his or her first task is to gather information that will rule out other possible reasons for the child's behavior. In ruling out other causes, the specialist checks the child's school and medical records. The specialist tries to sense whether the home and classroom environments are stressful or chaotic, and how the child's parents and teachers deal with the child. They may have a doctor look for such problems as emotional disorders, undetectable (petit mal) seizures, and poor vision or hearing. Most schools automatically screen for vision and hearing, so this information is often already on record. A doctor may also look for allergies or nutrition problems like chronic "caffeine highs" that might make the child seem overly active.

Next the specialist gathers information on the child's ongoing behavior in order to compare these behaviors to the symptoms and diagnostic criteria listed in the DSM (Diagnostic and Statistical Manual of Mental Disorders). This involves talking with the child and if possible, observing the child in class and in other settings.

The child's teachers, past and present, are asked to rate their observations of the child's behavior on standardized evaluation forms to compare the childžs behaviors to those of other children the same age. Of course, rating scales are subjective--tthey only capture the teacher's personal perception of the child. Even so, because teachers get to know so many children, their judgment of how a child compares to others is usually accurate.

The specialist interviews the child's teachers, parents, and other people who know the child well, such as school staff and baby-sitters. Parents are asked to describe their child's behavior in a variety of situations. They may also fill out a rating scale to indicate how severe and frequent the behaviors seem to be.

In some cases, the child may be checked for social adjustment and mental health. Tests of intelligence and learning achievement may be given to see if the child has a learning disability and whether the disabilities are in all or only certain parts of the school curriculum.

In looking at the data, the specialist pays special attention to the child's behavior during noisy or unstructured situations, like parties, or during tasks that require sustained attention, like reading, working math problems, or playing a board game. Behavior during free play or while getting individual attention is given less importance in the evaluation. In such situations, most children with ADHD are able to control their behavior and perform well.

The specialist then pieces together a profile of the child's behavior. Which ADHD-like behaviors listed in the DSM does the child show? How often? In what situations? How long has the child been doing them? How old was the child when the problem started? Are the behaviors seriously interfering with the child's friendships, school activities, or home life? Does the child have any other related problems? The answers to these questions help identify whether the child's hyperactivity, impulsivity, and inattention are significant and long-standing. If so, the child may be diagnosed with ADHD.

Adults are diagnosed for ADHD based on their performance at home and at work. When possible, their parents are asked to rate the person's behavior as a child. A spouse or roommate can help rate and evaluate current behaviors. But for the most part, adults are asked to describe their own experiences. One symptom is a sense of frustration. Since people with ADHD are often bright and creative, they often report feeling frustrated that they're not living up to their potential. Many also feel restless and are easily bored. Some say they need to seek novelty and excitement to help channel the whirlwind in their minds. Although it may be impossible to document when these behaviors first started, most adults with ADHD can give examples of being inattentive, impulsive, overly active, impatient, and disorganized most of their lives.

Until recent years, adults were not thought to have ADHD, so many adults with ongoing symptoms have never been diagnosed. People like Henry go for decades knowing that something is wrong, but not knowing what it is. Psychotherapy and medication for anxiety, depression, or manic-depression fail to help much, simply because the ADHD itself is not being addressed. Yet half the children with ADHD continue to have symptoms through adulthood. The recent awareness of adult ADHD means that many people can finally be correctly diagnosed and treated.

A correct diagnosis lets people move forward in their lives. Once the disorder is known, they can begin to receive whatever combination of educational, medical, and emotional help they need.

An effective treatment plan helps people with ADHD and their families at many levels. For adults with ADHD, the treatment plan may include medication, along with practical and emotional support. For children and adolescents, it may include providing an appropriate classroom setting, the right medication, and helping parents to manage their child's behavior.
