Part I
Attention deficit hyperactivity disorder (ADHD) is one of the most
common childhood disorders and can continue through adolescence and
adulthood. Symptoms include difficulty staying focused and paying
attention, difficulty controlling behavior, and hyperactivity
(over-activity).
ADHD has three subtypes:
1
- Predominantly hyperactive-impulsive
- Most symptoms (six or more) are in the hyperactivity-impulsivity categories.
- Fewer than six symptoms of inattention are present, although inattention may still be present to some degree.
- Predominantly inattentive
- The
majority of symptoms (six or more) are in the inattention category and
fewer than six symptoms of hyperactivity-impulsivity are present,
although hyperactivity-impulsivity may still be present to some degree.
- Children
with this subtype are less likely to act out or have difficulties
getting along with other children. They may sit quietly, but they are
not paying attention to what they are doing. Therefore, the child may be
overlooked, and parents and teachers may not notice that he or she has
ADHD.
- Combined hyperactive-impulsive and inattentive
- Six or more symptoms of inattention and six or more symptoms of hyperactivity-impulsivity are present.
- Most children have the combined type of ADHD.
Treatments
can relieve many of the disorder's symptoms, but there is no cure. With
treatment, most people with ADHD can be successful in school and lead
productive lives. Researchers are developing more effective treatments
and interventions, and using new tools such as brain imaging, to better
understand ADHD and to find more effective ways to treat and prevent it.
What are the symptoms of ADHD in children?
Inattention, hyperactivity, and impulsivity are the key behaviors of
ADHD. It is normal for all children to be inattentive, hyperactive, or
impulsive sometimes, but for children with ADHD, these behaviors are
more severe and occur more often. To be diagnosed with the disorder, a
child must have symptoms for 6 or more months and to a degree that is
greater than other children of the same age.
Children who have symptoms of
inattention may:
- Be easily distracted, miss details, forget things, and frequently switch from one activity to another
- Have difficulty focusing on one thing
- Become bored with a task after only a few minutes, unless they are doing something enjoyable
- Have difficulty focusing attention on organizing and completing a task or learning something new
- Have
trouble completing or turning in homework assignments, often losing
things (e.g., pencils, toys, assignments) needed to complete tasks or
activities
- Not seem to listen when spoken to
- Daydream, become easily confused, and move slowly
- Have difficulty processing information as quickly and accurately as others
- Struggle to follow instructions.
Children who have symptoms of
hyperactivity may:
- Fidget and squirm in their seats
- Talk nonstop
- Dash around, touching or playing with anything and everything in sight
- Have trouble sitting still during dinner, school, and story time
- Be constantly in motion
- Have difficulty doing quiet tasks or activities.
Children who have symptoms of
impulsivity may:
- Be very impatient
- Blurt out inappropriate comments, show their emotions without restraint, and act without regard for consequences
- Have difficulty waiting for things they want or waiting their turns in games
- Often interrupt conversations or others' activities.
ADHD Can Be Mistaken for Other Problems
Parents
and teachers can miss the fact that children with symptoms of
inattention have the disorder because they are often quiet and less
likely to act out. They may sit quietly, seeming to work, but they are
often not paying attention to what they are doing. They may get along
well with other children, compared with those with the other subtypes,
who tend to have social problems. But children with the inattentive kind
of ADHD are not the only ones whose disorders can be missed. For
example, adults may think that children with the hyperactive and
impulsive subtypes just have emotional or disciplinary problems.
What Causes ADHD?
Scientists are not sure what causes ADHD, although many studies
suggest that genes play a large role. Like many other illnesses, ADHD
probably results from a combination of factors. In addition to genetics,
researchers are looking at possible environmental factors, and are
studying how brain injuries, nutrition, and the social environment might
contribute to ADHD.
Genes. Inherited from our
parents, genes are the "blueprints" for who we are. Results from several
international studies of twins show that ADHD often runs in families.
Researchers are looking at several genes that may make people more
likely to develop the disorder.
2,3 Knowing the genes involved
may one day help researchers prevent the disorder before symptoms
develop. Learning about specific genes could also lead to better
treatments.
Children with ADHD who carry a particular version of a
certain gene have thinner brain tissue in the areas of the brain
associated with attention. This NIMH research showed that the difference
was not permanent, however, and as children with this gene grew up, the
brain developed to a normal level of thickness. Their ADHD symptoms
also improved.
4
Environmental factors. Studies suggest a potential link between cigarette smoking and alcohol use during pregnancy and ADHD in children.
5,6
In addition, preschoolers who are exposed to high levels of lead, which
can sometimes be found in plumbing fixtures or paint in old buildings,
may have a higher risk of developing ADHD.
7
Brain injuries.
Children who have suffered a brain injury may show some behaviors
similar to those of ADHD. However, only a small percentage of children
with ADHD have suffered a traumatic brain injury.
Sugar.
The idea that refined sugar causes ADHD or makes symptoms worse is
popular, but more research discounts this theory than supports it. In
one study, researchers gave children foods containing either sugar or a
sugar substitute every other day. The children who received sugar showed
no different behavior or learning capabilities than those who received
the sugar substitute.
8 Another study in which children were given higher than average amounts of sugar or sugar substitutes showed similar results.
9
In
another study, children who were considered sugar-sensitive by their
mothers were given the sugar substitute aspartame, also known as
Nutrasweet. Although
all the children got aspartame, half their
mothers were told their children were given sugar, and the other half
were told their children were given aspartame. The mothers who thought
their children had gotten sugar rated them as more hyperactive than the
other children and were more critical of their behavior, compared to
mothers who
thought their children received aspartame.
10
Food additives.
Recent British research indicates a possible link between consumption
of certain food additives like artificial colors or preservatives, and
an increase in activity.
11 Research is under way to confirm the findings and to learn more about how food additives may affect hyperactivity.
How is ADHD diagnosed?
Children mature at different rates and have different personalities,
temperaments, and energy levels. Most children get distracted, act
impulsively, and struggle to concentrate at one time or another.
Sometimes, these normal factors may be mistaken for ADHD. ADHD symptoms
usually appear early in life, often between the ages of 3 and 6, and
because symptoms vary from person to person, the disorder can be hard to
diagnose. Parents may first notice that their child loses interest in
things sooner than other children, or seems constantly "out of control."
Often, teachers notice the symptoms first, when a child has trouble
following rules, or frequently "spaces out" in the classroom or on the
playground.
No single test can diagnose a child as having ADHD.
Instead, a licensed health professional needs to gather information
about the child, and his or her behavior and environment. A family may
want to first talk with the child's pediatrician. Some pediatricians can
assess the child themselves, but many will refer the family to a mental
health specialist with experience in childhood mental disorders such as
ADHD. The pediatrician or mental health specialist will first try to
rule out other possibilities for the symptoms. For example, certain
situations, events, or health conditions may cause temporary behaviors
in a child that seem like ADHD.
Between them, the referring pediatrician and specialist will determine if a child:
- Is experiencing undetected seizures that could be associated with other medical conditions
- Has a middle ear infection that is causing hearing problems
- Has any undetected hearing or vision problems
- Has any medical problems that affect thinking and behavior
- Has any learning disabilities
- Has anxiety or depression, or other psychiatric problems that might cause ADHD-like symptoms
- Has been affected by a significant and sudden change, such as the death of a family member, a divorce, or parent's job loss.
A
specialist will also check school and medical records for clues, to see
if the child's home or school settings appear unusually stressful or
disrupted, and gather information from the child's parents and teachers.
Coaches, babysitters, and other adults who know the child well also may
be consulted.
The specialist also will ask:
- Are the behaviors excessive and long-term, and do they affect all aspects of the child's life?
- Do they happen more often in this child compared with the child's peers?
- Are the behaviors a continuous problem or a response to a temporary situation?
- Do the behaviors occur in several settings or only in one place, such as the playground, classroom, or home?
The
specialist pays close attention to the child's behavior during
different situations. Some situations are highly structured, some have
less structure. Others would require the child to keep paying attention.
Most children with ADHD are better able to control their behaviors in
situations where they are getting individual attention and when they are
free to focus on enjoyable activities. These types of situations are
less important in the assessment. A child also may be evaluated to see
how he or she acts in social situations, and may be given tests of
intellectual ability and academic achievement to see if he or she has a
learning disability.
Finally, if after gathering all this
information the child meets the criteria for ADHD, he or she will be
diagnosed with the disorder.
How is ADHD treated?
Currently available treatments focus on reducing the symptoms of ADHD
and improving functioning. Treatments include medication, various types
of psychotherapy, education or training, or a combination of
treatments.
Medications
The most common
type of medication used for treating ADHD is called a "stimulant."
Although it may seem unusual to treat ADHD with a medication considered a
stimulant, it actually has a calming effect on children with ADHD. Many
types of stimulant medications are available. A few other ADHD
medications are non-stimulants and work differently than stimulants. For
many children, ADHD medications reduce hyperactivity and impulsivity
and improve their ability to focus, work, and learn. Medication also may
improve physical coordination.
However, a one-size-fits-all
approach does not apply for all children with ADHD. What works for one
child might not work for another. One child might have side effects with
a certain medication, while another child may not. Sometimes several
different medications or dosages must be tried before finding one that
works for a particular child. Any child taking medications must be
monitored closely and carefully by caregivers and doctors.
Stimulant
medications come in different forms, such as a pill, capsule, liquid,
or skin patch. Some medications also come in short-acting, long-acting,
or extended release varieties. In each of these varieties, the active
ingredient is the same, but it is released differently in the body.
Long-acting or extended release forms often allow a child to take the
medication just once a day before school, so they don't have to make a
daily trip to the school nurse for another dose. Parents and doctors
should decide together which medication is best for the child and
whether the child needs medication only for school hours or for evenings
and weekends, too.
