Attention Deficit Hyperactivity Essay, Research Paper

Attention-Deficit Hyperactivity Disorder or Hyperactivity (ADHD), disorder

beginning in childhood, characterized by a persistent inability to sit still,

focus attention on specific tasks, and control impulses. Children with ADHD show

these behaviors more frequently and severely than other children of the same

age. A person with ADHD may have difficulty with school, work, friendships, or

family life. ADHD has also been referred to as attention-deficit disorder,

hyperkinesis, minimal brain dysfunction, and minimal brain damage.

Attention-deficit hyperactivity disorder is one of the most common mental

disorders of childhood, affecting 3 to 5 percent of school-age children. The

disorder occurs at least four times more often in boys than in girls. Although

the symptoms sometimes disappear with age, ADHD can persist into adolescence and

adulthood. Some estimates show that up to 2 percent of adults have ADHD. II

DIAGNOSIS Diagnosing ADHD is difficult because most children are inattentive,

hyperactive, and impulsive at least some of the time. In diagnosing ADHD,

experts use guidelines listed in the Diagnostic and Statistical Manual of Mental

Disorders. These guidelines require that a child show behaviors typical of ADHD

before the age of seven. The behaviors must last for at least six months, and

must occur more frequently than in other children of the same age. The behaviors

also must occur in at least two settings, such as classroom and home, rather

than just at a single setting. Controversy exists over the diagnosis of ADHD.

Physicians in the United States diagnose the disorder more often than doctors

elsewhere in the world. Critics regard this discrepancy as evidence that

physicians and psychologists too often apply psychiatric labels to children who

are naturally more active or simply nuisances to teachers and parents. III

CHARACTERISTICS Children and adults with ADHD consistently show various degrees

of inattention, hyperactivity, and impulsiveness. Inattention means that people

with ADHD have difficulty keeping their minds on one thing. They may get bored

with homework or other tasks after a few minutes, make careless mistakes, have

trouble listening, and seem to daydream. However, children with ADHD sometimes

can concentrate on and complete new or unusually interesting tasks.

Hyperactivity involves almost constant motion, as if driven by a motor. Children

may squirm and fidget at their desks in school, get up often to roam around the

room, constantly touch things, disturb other people, tap pencils, and talk

constantly. ADHD also makes children unusually impulsive, so that they act

before thinking. They may run into the street without looking, blurt out

inappropriate comments in class, interrupt conversations, and be unusually

clumsy or accident-prone. Children with ADHD often have severe learning problems

because of their difficulties in paying attention, following instructions, and

completing tasks. In addition, their disruptive, demanding behavior makes them

unpopular with peers. Children with ADHD often receive constant criticism and

correction from teachers and parents, who believe the behavior, is intentional.

The combination of negative feedback, poor academic achievement, and social

problems may contribute to low self-esteem and other emotional problems. IV

CAUSES Scientists do not know what causes ADHD. However, they have discredited

many theories that once were widely accepted. One theory contended that ADHD

resulted from minor head injuries or undetectable brain damage due to infections

or complications during birth. Experts called ADHD "minimal brain

damage" and "minimal brain dysfunction" when this theory was

popular in the early 1970s. Another theory linked ADHD with consumption of

refined sugar and food additives. Scientists questioned this theory when studies

showed that few children with ADHD benefited from diets restricting sugar and

food colorings. Most experts also reject the idea that poor parenting or a

dysfunctional home environment causes ADHD. Most scientists regard ADHD as a

biological disorder caused by abnormalities in the brain. Studies have shown

that areas of the brain that control attention span and limit impulsive behavior

are less active in people with ADHD. In addition, ADHD seems to run in families,

suggesting that genetic factors may play an important role (seeGenetics). One

study showed that about one-third of fathers who had ADHD in childhood have

children with ADHD. V TREATMENT Although there is no cure for ADHD, a variety of

treatments may help children with this disorder. These include medication,

counseling, social skills training, and other methods. A Medication Drugs are

the most common treatment for ADHD and can help reduce symptoms of the disorder.

Physicians usually prescribe one of three drugs: methylphenidate (Ritalin),

dextroamphetamine (Dexedrine or DextroStat), and pemoline (Cylert). These drugs

are normally stimulants, yet they ease hyperactivity and other symptoms in 90

percent of children with ADHD. The drugs work by altering levels of

neurotransmitters, brain chemicals that transmit nerve signals. A newer

stimulant used to treat ADHD, Adderall, combines dextroamphetamine and

amphetamine. Medical experts regard stimulants as safe. The most common side

effects include stomachaches, loss of appetite, nervousness, and insomnia. Drug

therapy may slow a child?s rate of growth temporarily, but growth usually

returns to normal during adolescence. Low doses of stimulants do not cause a

"high" sensation, sedate the child, or cause addiction. Experts often

recommend that children take medication only during school, with medication

breaks on weekends and holidays to reduce unwanted side effects. Doctors may

prescribe other types of drugs if stimulants do not prove effective. Critics

argue that physicians medicate too many children who do not have ADHD. They

point out that allergies, depression, anxiety, and conflicts with teachers or

parents, and other problems can make normal children seem hyperactive,

impulsive, and distracted. B Other Therapies Most children with ADHD need more

than medication. Drugs only relieve symptoms of ADHD, which usually return when

medication is discontinued. Although drugs help a child to concentrate and

complete schoolwork, they cannot increase a child?s knowledge, teach academic

skills, or directly alter underlying learning disorders or other problems.

Experts cite the need for more information on whether medication improves a

child?s chances for a successful career. Children may benefit from several

different kinds of therapy. Psychological counseling, for instance, can help

them recognize and deal with negative feelings that result from their symptoms.

Social skills training can help them recognize how their behavior affects other

people and help them develop more appropriate behavior. Children with ADHD also

may benefit from special academic tutors who show them how to break school

assignments down into small parts that can be completed one at a time. Because

children with ADHD often cause family turmoil, parents and other family members

may benefit from therapy or support groups in which other parents share their

experiences. Parental skills training can teach parents to manage a child?s

behavior with praise and other rewards, and with penalties such as

"time-outs" in which a child must sit alone to calm down. VI ADHD IN

ADULTS Many children with ADHD continue to have problems as adolescents and

adults. Adults with ADHD may be unusually impatient and restless and may become

bored before finishing a task. They may constantly arrive late for appointments,

lose things, change jobs often, and fail to organize their time or set

priorities, and have difficulty maintaining friendships and other relationships.

Studies suggest they are more likely than others to develop other mental

illnesses such as anxiety and depression, as well as substance-abuse problems

such as alcoholism and drug dependence.
