Deficit Hyperactivity Disorder
Introduction Attention Deficit Hyperactivity Disorder (ADHD)
is one of several childhood disorders brought into the public arena in
recent years. ADHD is the
current term for a specific developmental disorder describing specific
behavioral difficulties. Children
with ADHD experience an inability to sit still and pay attention in class.
ADHD is also characterized by multiple symptoms of persistent and
dysfunctional patterns of overactivity, impulsiveness, inattention, and
distractibility (Murphy, Cowan & Sederer, 2001).
°
ADHD
affects an estimated 4.1% of youths age 9 to 17 in a six-month period. °
About 2
to 3 times more boys that girls have ADHD. °
Children
with untreated ADHD have higher than normal rates of injury. °
ADHD
often co-occurs with other problems, such as depressive and anxiety
disorders, conduct disorder, drug abuse, or antisocial behavior. °
Symptoms
of ADHD usually become evident in preschool or early elementary years. °
The
disorder frequently persists into adolescence and into adulthood. °
Treatment
may be required throughout life.
Children
with ADHD experience harmful consequences as a result of their behavior.
They frequently experience peer rejection and academic and social
difficulties which may have long-term effects.
According to the National Institute of Mental Health (NIMH) these
children may have conduct disorders, experience drug abuse, exhibit
antisocial behavior, and incur injuries of all sorts. For many
individuals, the impact of ADHD continues into adulthood (NIMH, 2000). ADHD
has been given numerous names since it
was first documented. Some of
these names include Minimal Brain Dysfunction, Hyperkinetic Reaction of
Childhood, and Attention-Deficit Disorder With or Without Hyperactivity (CHADD,
2001).
According to the organization Children and Adults with Attention
Deficit Disorders (CHADD), with the Diagnostic and Statistical Manual,
4th Edition (DSM-IV) classification system, the disorder has been
renamed Attention Deficit Hyperactivity Disorder.
The current name reflects the importance of the inattention
characteristics of the disorder, as well as hyperactivity and impulsivity
(CHADD). Etiology ADHD is one of the best researched disorders in medicine. Studies
over the past 20 years involving twins, adoptions, and molecular
investigations have revealed that there is a genetic basis for the
disorder (MediFocus, 2002). Recent
imaging studies have documented the factual etiology of ADHD within
specific areas of the brain. Since ADHD runs in families, inheritance appears to be an
important factor. Families
with a child diagnosed with ADHD are more likely than those without ADHD
offspring to have family members with the disorder.
The heritability of ADHD averages approximately 80 percent,
rivaling the heritability factor for the trait of height (Barkley, 2001).
Several other developmental characteristics are associated with
ADHD. Perinatal injury,
malnutrition and substance exposure have also been linked to ADHD (Murphy
et al., 2001). Although a diagnostic test for ADHD is not available, (CHADD,
2001) there is insurmountable evidence supporting the validity of the
disorder. Comorbidity According to the National Institute of Mental Health (NIMH),
ADHD is not usually an isolated disorder and comorbidities may complicate
research studies. Specifically,
ADHD can occur with learning disabilities (15-25 percent), language
disorders (30-35 percent), conduct disorder (15-20 percent), oppositional
defiant disorder (up to 40 percent), mood disorders (15-20 percent), and
anxiety disorders (20-25 percent). Up
to 60 percent of children with tic disorders also have ADHD. Difficulties
with memory, cognitive processing, sequencing, motor skills, social
skills, modulation of emotional response, and response to discipline are
commonly associated with ADHD (NIMH, 2000).
Sleep disorders are also more prevalent in children who suffer from
ADHD. Treatment There is no treatment available to cure this disorder but
many treatments are available that effectively assist with its management.
A wide variety of treatments have been used to treat ADHD.
Foremost is education of the family and school staff about ADHD and
its management. A
Consensus Statement published by the National Institute of Mental Health
(1998) maintains that psychosocial treatment for ADHD has included a
number of behavioral strategies such as contingency management (e.g.,
point/token reward systems, and timeout) that typically are conducted in
the classroom, parent training (where the parent is taught child
management skills), clinical behavior therapy (parent, teacher, or both
are taught to use contingency management procedures), and
cognitive-behavioral treatment (e.g., self-monitoring, verbal
self-instruction, problem-solving strategies, self-reinforcement).
Clinical
behavior therapy, parent training, and contingency management have also
produced beneficial effects. Intensive direct interventions in children
with ADHD have produced improvements in key areas of functioning.
However, no studies have been conducted on some of these intensive
interventions or on how these interventions work with medications
prescribed for ADHD. Studies
did reveal that the combination of medication and behavioral treatments
usually were not much more effective then just medication alone.
However, combined treatment did result in more improved social
skills and accordingly, parents and teachers judged this treatment more
favorably.
Both medications and combined treatment was superior to routine
community care, which often involved the use of stimulants. Treatment
of ADHD requires behavioral, psychological and education components.
Education of the child and family regarding the nature of the
disorder and the methods proven to manage the disorder is crucial in its
management. Treatment must be
provided over long periods to assist those with ADHD in the ongoing
management of their disorder. Pharmacological Treatment The
following is based on information from the National Institute of Health
(1998). Stimulants are
generally considered to be first line treatment for ADHD and are often
prescribed by pediatricians, family physicians, specialized psychiatrists
or child psychiatrists. Short-term
trials of stimulants have supported the effectiveness of methylphenidate
dextroamphetamine (MPH). Few
differences have been found among these stimulants. However, MPH is the
most studied and the most often used of the stimulants.
For a variety of reasons including side effects, incomplete
responses or other circumstances, other medications are often recommended
in combination with or following unsuccessful trials of stimulants.
Trials
have found beneficial effects on the defining symptoms of ADHD and
associated aggressiveness for as long as medication is taken. However,
stimulant treatments may not regulate the entire range of behavior
problems, and children under treatment may still show a higher level of
behavioral problems than children without ADHD.
The findings also show that there is little improvement in academic
achievement or social skills. It
is critical that all involved with the use of these powerful medications
in children be clear as to what the treatment targets are for a particular
medication so that it can be maintained if it is successful and stopped if
it is not effective. Unproven Treatments There is a long history of a number of other interventions
for ADHD. These include: dietary replacement, exclusion, or
supplementation; various vitamin, mineral, or herbal regimens;
biofeedback; perceptual stimulation; and a host of others.
Some of the dietary elimination strategies showed intriguing
results, suggesting the need for future research. Although these
treatments have generated considerable interest and there are some
controlled and uncontrolled studies using various treatment strategies,
the research regarding these interventions is disproportionate, ranging
from no data to well-controlled trials.
Other
Important Treatment Elements It is important to realize that simple inattention or
hyperactivity by itself is not sufficient for diagnosis. ADHD has been
misdiagnosed in both children and adults by parents, teachers, and even by
patients themselves. Misbehavior by children or teens has been
inappropriately diagnosed and treated by persons looking for a simple
solution to personality difficulties in hopes of avoiding psychotherapy. While
no treatment can cure ADHD, caregivers and parents must educate themselves
about this disorder so they can understand it and design an effective
treatment plan. It is up to
the caregiver to become an informed consumer and learn to distinguish the
accurate information from the inaccurate.
Relatives, teachers and caretakers need to understand that ADHD is
neurobiological and a child’s brain works a bit differently.
ADHD is not the result of too much sugar or too little discipline. Effective
treatment involves the use of a multimodal approach that includes an
appropriate educational program; behavior modification; parent, child and
teacher education; and sometimes counseling and medication (CHADD, 2001).
Caregivers need to advocate for their children in academic settings
as well as in their home environment.
Children with ADHD are now eligible for special educational
services in the public schools under both the Individuals with
Disabilities in Education Act (IDEA: Public Law 101-476) and Section 504
of the Rehabilitation Act of 1973 (Public Law 93-112) (Barkley, 2001).
Maximizing positive outcomes under these laws is possible with
caregiver involvement. Effective
parent training teach strategies to modify behaviors and improve outcomes.
Because ADHD is highly hereditary, many parents of children with
ADHD discover that they too have ADHD when their child is diagnosed (CHADD,
2001). Parents with ADHD may need the same types of evaluation and
treatment that they seek for their children.
