What is Adult Attention Deficit Syndrome?

AADS/ADHD - Attention deficit syndrome is a highly publicized childhood disorder that affects approximately 3 percent to 5 percent of all children. What is much less well known is the probability that, of children who have ADHD, many will still have it as adults. Several studies done in recent years estimate that between 30 percent and 70 percent of children with ADHD continue to exhibit symptoms in the adult years.

The first studies on adults who were never diagnosed as children as having ADHD, but showed symptoms as adults, were done in the late 1970s by Drs. Paul Wender, Frederick Reimherr, and David Wood. These symptomatic adults were retrospectively diagnosed with ADHD after the researchers' interviews with their parents. The researchers developed clinical criteria for the diagnosis of adult ADHD (the Utah Criteria), which combined past history of ADHD with current evidence of ADHD behaviors. Other diagnostic assessments are now available; among them are the widely used Conners Rating Scale and the Brown Attention Deficit Disorder Scale.

Typically, adults with ADHD are unaware that they have this disorder—they often just feel that it's impossible to get organized, to stick to a job, to keep an appointment. The everyday tasks of getting up, getting dressed and ready for the day's work, getting to work on time, and being productive on the job can be major challenges for the ADHD adult.

What Causes ADHD?

One of the first questions a parent will have is "Why? What went wrong?" "Did I do something to cause this?" There is little compelling evidence at this time that ADHD can arise purely from social factors or child-rearing methods. Most substantiated causes appear to fall in the realm of neurobiology and genetics. This is not to say that environmental factors may not influence the severity of the disorder, and especially the degree of impairment and suffering the child may experience, but that such factors do not seem to give rise to the condition by themselves.

The parents' focus should be on looking forward and finding the best possible way to help their child. Scientists are studying causes in an effort to identify better ways to treat, and perhaps someday, to prevent ADHD. They are finding more and more evidence that ADHD does not stem from the home environment, but from biological causes. Knowing this can remove a huge burden of guilt from parents who might blame themselves for their child's behavior.

Over the last few decades, scientists have come up with possible theories about what causes ADHD. Some of these theories have led to dead ends, some to exciting new avenues of investigation.

Environmental Agents.

Studies have shown a possible correlation between the use of cigarettes and alcohol during pregnancy and risk for ADHD in the offspring of that pregnancy. As a precaution, it is best during pregnancy to refrain from both cigarette and alcohol use.

Another environmental agent that may be associated with a higher risk of ADHD is high levels of lead in the bodies of young preschool children. Since lead is no longer allowed in paint and is usually found only in older buildings, exposure to toxic levels is not as prevalent as it once was. Children who live in old buildings in which lead still exists in the plumbing or in lead paint that has been painted over may be at risk.

Brain Injury.

One early theory was that attention disorders were caused by brain injury. Some children who have suffered accidents leading to brain injury may show some signs of behavior similar to that of ADHD, but only a small percentage of children with ADHD have been found to have suffered a traumatic brain injury.

Food Additives and Sugar.

It has been suggested that attention disorders are caused by refined sugar or food additives, or that symptoms of ADHD are exacerbated by sugar or food additives. In 1982, the National Institutes of Health held a scientific consensus conference to discuss this issue. It was found that diet restrictions helped about 5 percent of children with ADHD, mostly young children who had food allergies. A more recent study on the effect of sugar on children, using sugar one day and a sugar substitute on alternate days, without parents, staff, or children knowing which substance was being used, showed no significant effects of the sugar on behavior or learning.

In another study, children whose mothers felt they were sugar-sensitive were given aspartame as a substitute for sugar. Half the mothers were told their children were given sugar, half that their children were given aspartame. The mothers who thought their children had received sugar rated them as more hyperactive than the other children and were more critical of their behavior.

Genetics.

Attention disorders often run in families, so there are likely to be genetic influences. Studies indicate that 25 percent of the close relatives in the families of ADHD children also have ADHD, whereas the rate is about 5 percent in the general population. Many studies of twins now show that a strong genetic influence exists in the disorder.

Researchers continue to study the genetic contribution to ADHD and to identify the genes that cause a person to be susceptible to ADHD. Since its inception in 1999, the Attention-Deficit Hyperactivity Disorder Molecular Genetics Network has served as a way for researchers to share findings regarding possible genetic influences on ADHD.

Recent Studies on Causes of ADHD.

Some knowledge of the structure of the brain is helpful in understanding the research scientists are doing in searching for a physical basis for attention deficit hyperactivity disorder. One part of the brain that scientists have focused on in their search is the frontal lobes of the cerebrum. The frontal lobes allow us to solve problems, plan ahead, understand the behavior of others, and restrain our impulses. The two frontal lobes, the right and the left, communicate with each other through the corpus callosum, (nerve fibers that connect the right and left frontal lobes).

The basal ganglia are the interconnected gray masses deep in the cerebral hemisphere that serve as the connection between the cerebrum and the cerebellum and, with the cerebellum, are responsible for motor coordination. The cerebellum is divided into three parts. The middle part is called the vermis.

All of these parts of the brain have been studied through the use of various methods for seeing into or imaging the brain. These methods include functional magnetic resonance imaging (fMRI) positron emission tomography (PET), and single photon emission computed tomography (SPECT). The main or central psychological deficits in those with ADHD have been linked through these studies. By 2002 the researchers in the NIMH Child Psychiatry Branch had studied 152 boys and girls with ADHD, matched with 139 age- and gender-matched controls without ADHD. The children were scanned at least twice, some as many as four times over a decade. As a group, the ADHD children showed 3-4 percent smaller brain volumes in all regions—the frontal lobes, temporal gray matter, caudate nucleus, and cerebellum.

This study also showed that the ADHD children who were on medication had a white matter volume that did not differ from that of controls. Those never-medicated patients had an abnormally small volume of white matter. The white matter consists of fibers that establish long-distance connections between brain regions. It normally thickens as a child grows older and the brain matures.

Although this long-term study used MRI to scan the children's brains, the researchers stressed that MRI remains a research tool and cannot be used to diagnose ADHD in any given child. This is true for other neurological methods of evaluating the brain, such as PET and SPECT.

Diagnosing ADHD in an Adult.

Diagnosing an adult with ADHD is not easy. Many times, when a child is diagnosed with the disorder, a parent will recognize that he or she has many of the same symptoms the child has and, for the first time, will begin to understand some of the traits that have given him or her trouble for years—distractibility, impulsivity, restlessness. Other adults will seek professional help for depression or anxiety and will find out that the root cause of some of their emotional problems is ADHD. They may have a history of school failures or problems at work. Often they have been involved in frequent automobile accidents.

To be diagnosed with ADHD, an adult must have childhood-onset, persistent, and current symptoms. The accuracy of the diagnosis of adult ADHD is of utmost importance and should be made by a clinician with expertise in the area of attention dysfunction. For an accurate diagnosis, a history of the patient's childhood behavior, together with an interview with his life partner, a parent, close friend, or other close associate, will be needed. A physical examination and psychological tests should also be given. Comorbidity with other conditions may exist such as specific learning disabilities, anxiety, or affective disorders.

A correct diagnosis of ADHD can bring a sense of relief. The individual has brought into adulthood many negative perceptions of himself that may have led to low esteem. Now he can begin to understand why he has some of his problems and can begin to face them. This may mean, not only treatment for ADHD but also psychotherapy that can help him cope with the anger he feels about the failure to diagnose the disorder when he was younger.

Treatment of ADHD in an Adult.

Medications. As with children, if adults take a medication for ADHD, they often start with a stimulant medication. The stimulant medications affect the regulation of two neurotransmitters, norepinephrine and dopamine. The newest medication approved for ADHD by the FDA, atomoxetine (Strattera®), has been tested in controlled studies in both children and adults and has been found to be effective.

Antidepressants are considered a second choice for treatment of adults with ADHD. The older antidepressants, the tricyclics, are sometimes used because they, like the stimulants, affect norepinephrine and dopamine. Venlafaxine (Effexor®), a newer antidepressant, is also used for its effect on norepinephrine. Bupropion (Wellbutrin®), an antidepressant with an indirect effect on the neurotransmitter dopamine, has been useful in clinical trials on the treatment of ADHD in both children and adults. It has the added attraction of being useful in reducing cigarette smoking.

In prescribing for an adult, special considerations are made. The adult may need less of the medication for his weight. A medication may have a longer "half-life" in an adult. The adult may take other medications for physical problems such as diabetes or high blood pressure. Often the adult is also taking a medication for anxiety or depression. All of these variables must be taken into account before a medication is prescribed.

Education and psychotherapy. Although medication gives needed support, the individual must succeed on his own. To help in this struggle, both "psychoeducation" and individual psychotherapy can be helpful. A professional coach can help the ADHD adult learn how to organize his life by using "props"—a large calendar posted where it will be seen in the morning, date books, lists, reminder notes, and have a special place for keys, bills, and the paperwork of everyday life. Tasks can be organized into sections, so that completion of each part can give a sense of accomplishment. Above all, ADHD adults should learn as much as they can about their disorder.

Psychotherapy can be a useful adjunct to medication and education. First, just remembering to keep an appointment with the therapist is a step toward keeping to a routine. Therapy can help change a long-standing poor self-image by examining the experiences that produced it. The therapist can encourage the ADHD patient to adjust to changes brought into his life by treatment—the perceived loss of impulsivity and love of risk-taking, the new sensation of thinking before acting. As the patient begins to have small successes in his new ability to bring organization out of the complexities of his or her life, he or she can begin to appreciate the characteristics of ADHD that are positive—boundless energy, warmth, and enthusiasm.
