What is attention-deficit/hyperactivity disorder (ADHD)?
Attention deficit/hyperactivity disorder (ADHD) is the most
common mental health problem in children. Children with ADHD
often have problems with paying attention, being unable to sit
still, and doing things without thinking first. It is also
called attention deficit disorder (ADD).
The disorder begins in the preschool years and may last into
adulthood. About one-third of children with ADHD also have
learning problems such as a reading disability. About half of
ADHD children and teenagers have behavior problems. This may
include breaking rules, talking back, and hitting other
children.
ADHD is 7 times more common in boys than girls. Girls are
more likely to have trouble paying attention. Boys are more
likely to be hyperactive.
How does it occur?
The exact cause of ADHD has not yet been found. ADHD seems to
run in families. If a parent, uncle, or grandparent has ADHD,
other family members may also develop it. People with ADHD
have several small differences in the brain. These
differences are in the front part of the brain (an area
involved in self-control) and in some parts in the center of
the brain.
Much research has looked at whether ADHD is caused by sugar or
things added to foods such as preservatives and coloring. The
evidence has not connected these with ADHD. Allergies are not
a common factor in causing ADHD either.
What are the symptoms?
The symptoms of ADHD, especially hyperactivity, usually
appear by age 2 or 3 and by first grade at the latest. There
are 3 main symptoms of ADHD: distractibility, impulsiveness,
and hyperactivity.
Children and teens with ADHD:
- Are distracted by what is going on around him or her.
- Have trouble waiting in line or taking turns.
- Start many projects but do not finish things.
- React quickly without thinking of the outcome.
- Are quick to anger.
- Fidget and cannot sit still.
- Walk, run, or climb around when others are seated.
- Get bored very quickly.
There are 3 forms of ADHD:
- Combined ADHD. Your child has all of the main symptoms:
distractibility, poor impulse control, and hyperactivity.
- Predominately inattentive. Your child has problems with
focus and attention. This form of ADD is often missed
because there may be very little hyperactivity or
impulsivity. This form is especially common among girls.
- Predominately impulsive-hyperactive type. Poor
self-control is the main problem.
How is it diagnosed?
Your health care provider will ask about the symptoms and will
observe your child's behavior for signs of ADHD. Parents and
teachers may be asked questions about ADHD symptoms. Your
child may need to see a mental health professional for tests
of attention and self-control. There are no useful physical
tests such as blood tests or brain scans for diagnosing ADHD.
To diagnose ADHD, it must be clear that the symptoms persist
and interfere in a major way with daily life.
How is it treated?
The treatment of ADHD may involve 3 types of treatment:
- Learning coping skills: Children with ADHD learn to manage
highly stimulating situations that distract and
over-excite them. They should learn to study in quiet places
and to take frequent breaks. In a classroom, they do
best at individual desks rather than at a table with
others. They also often find that background
instrumental music is helpful. Children with ADHD need
more structure and daily routine than most people.
- Behavioral training: Behavior programs may help your
child develop a longer attention span and be able to sit
still.
- Medicines: Since the 1920s, medicines such as
methylphenidate (Ritalin) and dextroamphetamine (Dexedrine)
have been used. They are stimulants, and appear to
stimulate the self-control areas of the brain. Another
medicine often used is dextroamphetamine/amphetamine
(Adderall). These medicines do not slow you down, but
rather increase self-regulation. About 70% of children
with ADHD improve with these medicines. The most common
side effects are loss of appetite and trouble getting to
sleep. Your child's dosage will be gradually adjusted to
reduce side effects. Sometimes, medicines are used only on
school days. When these medicines are not effective, there
are other medicines that can help with ADHD.
Claims have been made that many health foods and supplements
help with ADHD. Limiting sugar, food additives, or food
colorings is not effective in treating ADHD. Omega fatty acid
supplements and certain vitamins and minerals may help
symptoms of ADHD.
How long do the effects last?
About half of people with ADHD seem to "grow out of it" by
their early twenties. The other half show a slight change or
no change in symptoms as they grow into adulthood. Being more
patient and better able to sit still are the most common
improvements between late childhood and young adulthood.
What can I do to help my child?
There are many ways to help manage ADHD:
- When children need to read or concentrate, have them work
away from the sounds of television, radio, or others talking.
- When your child needs to concentrate, try having low-level
background sound such as white noise or instrumental music.
- Encourage your child to do tasks in short blocks of time
with breaks in between.
- Help your child to follow a very structured daily routine.
- If your child has trouble slowing down at bedtime, a
planned quiet time before bedtime and background music
when falling asleep are often helpful.
- Encourage your child to exercise regularly.
- Help your child to get enough sleep.
- Help your child to eat a healthy diet.
- Limit caffeine.
