ADHD

Upon shadowing a fourth grade teacher at Deer Ridge Elementary School, I decided to talk with her about the students in her classroom. Mrs. Riley first set the scene of the school for me by stating that it was in the southwest suburban area of Fort Wayne, Indiana, and this particular school was not hurting for money. She then began to explain the different children in her classroom. There were twenty-eight students from a variety of different backgrounds. There were also two students with ADHD. My first thought was, "What exactly is ADHD?" and, "Would these two children stick out from the rest of the students in the classroom?".

These questions are commonly asked by people who are unfamiliar with ADHD,…show more content…

It serves as the brain’s command center, that helps with "editing" behavior, resisting distractions, and developing awareness (NIMH, 1996). The caudate nucleus and globus pallidus, which are more commonly known as the basal ganglia, are located near the middle of the brain. They are "at least two of the clusters of nerve cells deep in the brain" (Barkley, 1998). The caudate nucleus and globus pallidus translate the commands, given by the prefrontal cortex, into action (NIMH, 1996). Researchers have found that these parts of the brain, which are in the right hemisphere of the brain, are smaller in children with ADHD than in children without this disorder (Barkley, 1998). The right hemisphere of the brain is normally larger than the left hemisphere, but some researchers have thought that due to this abnormality in ADHD children that this could be a cause of the disorder (Barkley, 1998).

Another hypothesis that has been considered for the cause of ADHD is genetic inheritance. It is stated in Barkley’s 1998 article in Scientific American that, "ADHD is a polygenic disorder—that is, more than one gene contributes to it." There has been many studies done with twins to help support this hypothesis. One of the largest studies was conducted by Helene Gjone, Jon M. Sundet, and Jim Stevenson, in which it involved many identical twins who had inherited the same genes. This

It could be a combination of the three symptoms. ADHD is most commonly found in children, but it can also be portrayed in adults.
Scientists are not sure what causes ADHD. Research has shown that genes, environmental, brain injuries, sugar, and food additives could all contribute to causing ADHD.

ADHD stands for Attention Deficient Hyperactivity Disorder. It is considered an intellectual disability. It causes a lack of focus, over activity, or lack of behavior control.

Scientists are not sure what causes ADHD. Research has shown that genes, environmental, brain injuries, sugar, and food additives could all contribute to causing ADHD. Many scientists believe genetics is the key factor of ADHD. People with ADHD are born with a gene that makes the brain tissue associated with attention not as thick as a person who is born without this gene. Since you brain develops as you grow, the brain tissue thickens as you grow too. This causes people to grow out of their ADHD like symptoms. Scientists also believe environmental factors play a key in ADHD also. Studies have shown that pre-kindergarteners exposed to large amounts of lead have a risk of devolving ADHD. Diet could also play a role in ADHD. British researchers found that food additives such as preservatives and artificial food coloring can increase activity in children.
As a person with ADHD I can tell you what the symptoms would be. Starting with the AD (attention deficient) in ADHD, I (and others with the disorder) have experienced lack of attention. Without medicine I tend to space out. Not daydream, but just stare off into space without thinking. When its time to settle down and start
