ADHD
is a disorder of the brain and behavior. It affects about 3 to 5% of
children. The symptoms start before seven years of age. Global
prevalence for children is approximately 5%, with wide variability
dependent on research methodologies utilized in studies. Attention
Deficit Hyperactivity Disorder, ADHD, is one of the most common mental
disorders that develop in children. Children with ADHD have impaired
functioning in multiple settings, including home, school, and in
relationships with peers. If untreated, the disorder can have long-term
adverse effects into adolescence and adulthood.
Symptoms:
The most common symptoms of ADHD are:
Impulsiveness:
acting
before thinking of consequences, jumping from one activity to another,
disorganization, tendency to interrupt other peoples' conversations
Hyperactivity:
restlessness, often characterized by an inability to sit still, fidgeting, squirminess, climbing on things, restless sleep.
Inattention:
easily distracted, day-dreaming, not finishing work, difficulty listening.
Subtypes:
ADHD has three subtypes:
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
Causes
A
specific cause of ADHD is not known. There are, however, a number of
factors that may contribute to ADHD including genetics, diet and social
and physical environments.
Genetic factors
Studies indicate
that the disorder is highly heritable and that genetics are a factor in
about 75% of ADHD cases. Hyperactivity also seems to be primarily a
genetic condition however other causes do have an effect.
Researchers
believe that a large majority of ADHD cases arise from a combination of
various genes, many of which affect dopamine ( a chemical in the brain)
transporters. The broad selection of targets indicates that ADHD does
not follow the traditional model of a "genetic disease" and should
therefore be viewed as a complex interaction among genetic and
environmental factors.
Environmental factors
Environmental
factors implicated include alcohol and tobacco smoke exposure during
pregnancy and environmental exposure to lead in very early life.
Complications during pregnancy and birth—including - premature
birth—might also play a role.
Diet
Additives
Studies have
found that dietary elimination of artificial food coloring and
preservatives provides a statistically significant benefit in children
with
Sugar regulation
A number of studies have found that sucrose
(sugar) has no effect on behavior and in particular it does not
exacerbate the symptoms of children diagnosed with ADHD
Omega-3 supplement
Preliminary
research suggests that Omega-3 supplementation might be effective in
the treatment of ADHD; however some of the studies give conflicting
results.
Social factors
There is no compelling evidence that
social factors alone can cause ADHD.[ Many researchers believe that
relationships with caregivers have a profound effect on attentional and
self-regulatory abilities. A study of foster children found that a high
number of them had symptoms closely resembling ADHD, while other
researchers have found behavior typical of ADHD in children who have
suffered violence and emotional abuse.
Head injury
ADHD
patients have been observed to have higher than average rates of head
injuries, however current evidence does not indicate that head injuries
are the cause of ADHD in the patients observed
Pathophysiology
One
study states that a delay in development of certain brain structures
like frontal cortex and temporal lobe occurs by an average of three
years of age. These structures are responsible for the ability to
control and focus thinking. On the other hand the motor cortex develops
faster than normal. It indicates the slower development of behavioral
control and faster development for advanced motor development may cause
increased attention deficits and hyperactivity.
Another study states
that there is unusual thinness of the cortex of the right side of the
brain, accounting for about 30% of genetic risk for ADHD. Also it has
been seen that this region normalizes in thickness during the teen
years showing improvement in clinical symptoms
Additionally,
SPECT scans found people with ADHD to have reduced blood circulation
(indicating low neural activity), and a significantly higher
concentration of dopamine transporters in the striatum which is in
charge of planning ahead. Medications focused on treating ADHD (such as
methylphenidate) work by reducing dopamine reuptake in certain areas of
the brain, such as those that control and regulate concentration. As
dopamine is a stimulant, this increases neural activity and thus blood
flow in these areas (blood flow is a marker for neural activity).
Treatment:
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. Methods of treatment usually involve some combination of
medications, behavior modifications, life-style changes, and counseling.
Lifestyle
Aerobic
fitness may improve cognitive functioning and neural organization
related to executive control during pre-adolescent development, though
more studies are needed in this area. One study suggests that athletic
performance in boys with ADHD may increase peer acceptance when
accompanied by fewer negative behaviors
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.
The side effects of stimulant medications:
The
most commonly reported side effects are decreased appetite, sleep
problems, anxiety, and irritability. Some children also report mild
stomachaches or headaches. Most side effects are minor and disappear
over time or if the dosage level is lowered.
Decreased appetite.
Be sure your child eats healthy meals. If this side effect does not go
away, talk to your child's doctor. Also talk to the doctor if you have
concerns about your child's growth or weight gain while he or she is
taking this medication.
Sleep problems. If a child cannot fall
asleep, the doctor may prescribe a lower dose of the medication or a
shorter-acting form. The doctor might also suggest giving the
medication earlier in the day, or stopping the afternoon or evening
dose. Adding a prescription for a low dose of an antidepressant or a
blood pressure medication called clonidine sometimes helps with sleep
problems. A consistent sleep routine that includes relaxing elements
like warm milk, soft music, or quiet activities in dim light, may also
help.
Less common side effects. A few children develop sudden,
repetitive movements or sounds called tics. These tics may or may not
be noticeable. Changing the medication dosage may make tics go away.
Some children also may have a personality change, such as appearing
"flat" or without emotion.
Psychotherapy:
Different types of
psychotherapy are used for ADHD. Behavioral therapy aims to help a
child change his or her behavior. It might involve practical
assistance, such as help organizing tasks or completing schoolwork, or
working through emotionally difficult events. Behavioral therapy also
teaches a child how to monitor his or her own behavior.
Learning
to give oneself praise or rewards for acting in a desired way, such as
controlling anger or thinking before acting, is another goal of
behavioral therapy.
Parents and teachers also can give positive
or negative feedback for certain behaviors. In addition, clear rules,
chore lists, and other structured routines can help a child control his
or her behavior.
Therapists may teach children social skills, such as how to wait their turn, share toys, ask for help, or respond to teasing.
Learning
to read facial expressions and the tone of voice in others, and how to
respond appropriately can also be part of social skills training.
Parenting
skills training helps parents learn how to use a system of rewards and
consequences to change a child's behavior. Parents are taught to give
immediate and positive feedback for behaviors they want to encourage,
and ignore or redirect behaviors they want to discourage. In some
cases, the use of "time-outs" may be used when the child's behavior
gets out of control. In a time-out, the child is removed from the
upsetting situation and sits alone for a short time to calm down.
Parents
are also encouraged to share a pleasant or relaxing activity with the
child, to notice and point out what the child does well, and to praise
the child's strengths and abilities.
They may also learn to
structure situations in more positive ways. For example, they may
restrict the number of playmates to one or two, so that their child
does not become over stimulated.
Or, if the child has trouble
completing tasks, parents can help their child divide large tasks into
smaller, more manageable steps. Also, parents may benefit from learning
stress-management techniques to increase their own ability to deal with
frustration, so that they can respond calmly to their child's behavior.
Sometimes,
the whole family may need therapy. Therapists can help family members
find better ways to handle disruptive behaviors and to encourage
behavior changes. Finally, support groups help parents and families
connect with others who have similar problems and concerns. Groups
often meet regularly to share frustrations and successes, to exchange
information about recommended specialists and strategies, and to talk
with experts.
