ADD and Ritalin

Attention Deficit Disorder (ADD) is a problem that affects 5% to 10% of all children. ADD affects more children than any other childhood problems except asthma. It is estimated to be the largest single cause for first referrals to child guidance clinics throughout the country, making up as many as 40% of those cases. Many ADD cases are not diagnosed because the problem most often does not show in the doctors office.

Current estimates suggest that approximately 50 to 65% of the children with ADD will have symptoms of the disorder as adolescents and adults. Although ADD has just recently been discovered and there is still relatively little known about it. In 1902, George Frederick Still believed the dilemma of the problem child was linked to a biological defect inherited from an injury at birth and not the result of the environment. Through 1930-40's stimulant drugs were first used to successfully treat many behavior problems due in part by Still's hypothesis. In 1960, Stella Chess researched in the field by writing about the "hyperactive child syndrome." She took Still's hypothesis further stating that the resulting behavior problems stem from a biological cause, although it is linked to a genetic inheritance rather then a birth defect from an injury. Finally, in 1980, the syndrome was named Attention Deficit Disorder, due in large part to Virginia Douglas's work to find accurate ways to diagnose it (Hallowell 2).

This is currently how it exists today, with the addition of a new category Attention Deficit Hyperactivity Disorder and there sub types. Most scientists now believe that an abnormality in brain chemistry could be to blame for the symptoms of Attention Deficit Disorder. The frontal lobes of the brain are believed to be responsible for the regulation of behavior and attention. They receive information from the lower brain, which regulates arousal and screens incoming messages from within and outside of the body. The limbic system, which is a group of related nervous system structures, located in the midbrain and linked to emotions and feelings then sends the messages to the frontal lobes. Finally, the frontal lobes are suspected to be the site of working memory, the place where information about the immediate environment is considered for memory storage, planning, and future-directed behavior.

Scientist believe the activity in the frontal lobes is depressed in people with ADD. Studies also show, a decrease in the ability of the Attention Deficit Disorder brain to use glucose, the body's main source of energy, leading to slower and less efficient activity. Neurotransmitters provide the connection between one nerve cell and another. It is also now suspected that people with Attention Deficit Disorder have a chemical imbalance of a class of neurotransmitter called catecholamine. Dopamine, helps to form a pathway between the motor center of the midbrain and the frontal lobes, as well as a pathway between the limbic system and the frontal lobes. Without enough dopamine and related catecholamine, such as serotonin and norepinephrine, the frontal lobes are under stimulated and thus unable to perform their complex functions efficiently.

Attention Deficit Disorder is primarily considered a genetic disorder. Which is why it is labeled an axis two in the DSM-IV. Studies show that 20-30% of all hyperactive children have at least one parent with ADD. However, not all cases of ADD are genetically linked. Some studies show that smoking, drinking alcohol, and using drugs during pregnancy, influenced a small percentage of ADD cases. Exposure to toxins, such as lead, may also alter the brain chemistry and function. Both of these issues are cause for concern for the at-risk population.

ADD generally affects males more often than females, in a 3:1 ratio. Because this disorder effects the brain detection of this condition is difficult. The accepted test, although today there has been an increase in research into ADD and subsequently now other tests. The test requires a nine-month observation of the person, as well as EEGs, MRIs, or a PET scan. During the nine months, the person has to show a certain number of the classic traits associated with the disorder. The EEG is used to record the amount of electrical activity that is happening in the brain. An MRI is an x-ray that shows the brain's anatomy however it is not a routine assessment. More recently, the way to diagnose ADD is the use of a PET scan, which measures the amount of activity in the brain.

There are two general categories for those diagnosed with Attention Deficit Disorder. One is ADHD (Attention Deficit Hyperactivity Disorder); this is the more prevalent of the two. A person with ADHD will show certain characteristics. Characteristics like, fidgeting, squirming, difficulty remaining seated, easily distracted, difficulty awaiting turn, interrupting, difficulty following directions, sustaining attention, shifting from one uncompleted task to another, not listening, following multiple directions, and frequently engaging in dangerous actions. The general diagnosis of ADD, as opposed to ADHD, has some, but not all of the above characteristics.

There are people who have been diagnosed with ADD whose characteristics are not hyperactive but the complete opposite, they are under active. This goes against the general notion that only kids who are hyperactive have ADD. These children often daydream and are never mentally present anywhere. They constantly drift off into their own world during classes or conversations. This type is more prevalent in females with ADD then in males. The underlining issues with these children are the inability to focus, they are too easily distracted. This form of ADD is the hardest to diagnose since it seems that these people simply need to "apply themselves more" or "get their act together."

Attention Deficit Disorder not only affects those afflicted in the classroom but at home as well. The rest of the families' daily routine may become a distraction to those afflicted with ADD. Sometimes a television or radio that is turned on in another room may become a distraction. What the ADD person needs is a sound screen. A sound screen is some form of constant noise that plays in the background, commonly a television or a radio. At first it may seem like a distraction, but in reality, if the TV or music forms a kind of "white noise" with an even level of intensity, which actually covers up discrepant noises that can be a distraction. "The hum of a ceiling fan or motor can do wonders to soothe and focus you" (Weiss.7).

Getting a family household to function smoothly is challenging for any family, with or without the presence of ADD. Adults and children suffering from Attention
