ADHD Explained

Posted by Richard Campbell On October - 12 - 2009 1 COMMENT

ADHD is not a neurological disorder. It is actually a neurobehavioral developmental disorder that affects an estimated 8% to 10% of school-age children.Boys are about three times more likely than girls to be diagnosed with it, though it’s not yet understood why.

Kids with ADHD act without thinking, are hyperactive, and have trouble focusing. They may understand what’s expected of them but have trouble following through because they can’t sit still, pay attention, or attend to details.

Of course, all kids (especially younger ones) act this way at times, particularly when they’re anxious or excited. But the difference with adhd is that symptoms are present over a longer period of time and occur in different settings. They impair a child’s ability to function socially, academically, and at home. The good news is that with proper treatment, kids with adhd can learn to successfully live with and manage their symptoms.

ADHD is present at birth. Thus the history will be chronic and pervasive. These behaviors will have been present since early life and will exist in most of these behaviors that establishes the diagnosis. The treatment involves raising the level of the deficient neurotransmitter. There are several medications that will accomplish this. One group works by increasing the production of the transmitter (ritalin, dextroampetamine, adderall). The second group works by decreasing the breakdown of this transmitter; thus, whatever is produced stays around longer (imipramine, desipramine, nortriptyline).

Learning disabilities are caused by “faulty wiring” in the cortex of the brain. The result is difficulty processing information. These processing problems might involve language, motor, cognitive, or executive functioning problems. The result will be problems with language, motor activity, reading, writing, math, organization, or other higher level tasks. Which disabilities an individual has will depend on the areas involved. When they will appear will depend on when the area of the brain that is wired differently begins to function.

An individual with ADHD finds it much more difficult to focus on something without being distracted. He has greater difficulty in controlling what he is doing or saying and is less able to control how much physical activity is appropriate for a particular situation compared to somebody without ADHD In other words, a person with ADHD is much more impulsive and restless.

Health care professionals may use any of the following terms when describing a child (or an older person) who is overactive and has difficulty concentrating -. Attention deficit, attention deficit hyperactivity disorder, hyperkinetic disorder, hyperactivity. North americans commonly use the terms add (attention deficit disorder) or ADHD (attention deficit hyperactivity disorder). In the uk hyperkinetic disorder is the official term.

People with attention deficit hyperactivity disorder (ADHD) is usually very difficult to concentrate and very hyperactive. The reason is that the influence of chemical substances called  dopamine that plays an important role in regulating mood or feelings.

Dopamine deficiency in the brain explains the clinical symptoms of ADHD which can include lack of concentration and lack of motivation that can lead to obesity.  This shows that ADHD is not only abnormalities in attention or concentration system in the brain but also abnormalities in the central motivation and emotion.

In order to help people with ADHD in the teaching-learning process, it must be ensured that all kinds of school works are interesting and fun, so people with ADHD will be motivated to learn and stimulate in concentration and focus training. It is expected this method can be used as a new weapon in fighting against the condition.

This method was discovered after conducting research using positron emission tomography (PET), by measuring the levels of two proteins of dopamine receptors and dopamine transporters in ADHD that low levels in two brain regions which are the nucleus accumbens and the midbrain. Both sections are responsible for emotion and motivation stimulus such as acceptance and teaching.

Patients with ADHD can be treated with stimulant medications to improve the levels of dopamine in the brain. These stimulants can be used to create fun environment and do things that will attract attention, This will help stimulate the brain that have low dopamine levels.
