Causes, incidence, and risk factors:
People with attention deficit disorder (A.D.D.) are easily distracted, have difficulty paying attention, and may be unable to focus more than a few moments on mental tasks. They may be physically active and behave impulsively.

There are 3 sub-categories of attention deficit disorder:

• attention deficit/hyperactivity disorder: combined type

• attention deficit/hyperactivity disorder: predominantly inattentive

• attention deficit/hyperactivity disorder: predominantly hyperactive or impulsive

The cause of attention deficit disorder is unknown. Some contributing factors include prenatal toxic exposure and prematurity. There frequently is a family history of school problems, behavioral disorders, or other psycho-social problems. There is sometimes a history of injuries to the central nervous system. However, there is no scientific evidence that shows conclusively that ANY of these factors directly cause attention deficit disorder.

The apparent incidence of A.D.D. has been increasing over the last 15 years, possibly related to better diagnosis, changing expectations, or problems with supportive social structures. The disorder affects 3 to 10% of all school-age boys and is 3 to 10 times more common in males than females.

Typically affected children, whether intellectually handicapped or not, perform poorly in school because of the inability to attend to tasks at hand or to sit still during the school day. The diagnosis is generally not considered until school age.

Prevention:
Attention deficit disorder is a complex issue, and many preventive measures have been proposed. None have been proven at this time.

Symptoms:
The symptoms typically begin by 3 years of age.

Signs and tests:
Clinical evaluation is indicated if A.D.D. is suspected.

Evaluation may include:

• parent and teacher questionnaires (Connors, Burks)

• psychological evaluation of the child AND family including IQ testing and psychological testing

• complete developmental, mental, nutritional, physical, and psychosocial examination

Treatment:
Many medication methods of treatment been tried. Attention deficit/hyperactivity disorder is usually treated with a course of medications followed by therapy and appropriate school placement. The primary medications used to treat attention deficit disorder include: (Never use any treatment before consulting a doctor)

• Dexedrine (dextroamphetamine)

• Ritalin (methylphenidate)

Sometimes, caffeine may also be used.

Therapy techniques include:

• behavior modification

• parent counseling

• individual psychotherapy

Other helpful techniques may include

• modifying the environment to limit distracting factors

• providing one-on-one instruction with teacher

Expectations (prognosis):
Studies have now shown that the problems of attention deficit disorder may persist into adulthood; however, adults are usually more capable of controlling behavior and masking difficulties. Careful attention to education, socialization, and understanding your expectations should allow the child to develop into a functional adult.

Complications:

• school failure

• school drop-out

• delinquency

• criminal behavior
