ADHD After shadowing a fourth grade teacher at Deer Ridge Elementary School, I decided to talk to her about the students in her class. Mrs. Riley first described the school scene to me stating that it was located in the southwest suburban area of ​​Fort Wayne, Indiana, and that this particular school was not bad for the money. He then began to explain to the different children in his class. There were twenty-eight students from different backgrounds. There were also two students with ADHD. My first thought was, “What exactly is ADHD?” and “Would these two children stand out from the rest of the students in class?” These questions are commonly asked by people who are unfamiliar with attention deficit hyperactivity disorder (ADHD). Children with ADHD exhibit specific symptoms, where no one is sure what causes these symptoms to appear. Some children with ADHD have other problems associated with this disorder, such as behavioral and social problems. Children with ADHD may stand out from other children, only if they have not been prescribed the appropriate treatment. ADHD is the “developmental failure in the brain circuitry that underlies inhibition and self-control” (Barkley, 1998), or “inability to inhibit thoughts” (NIMH, 1996), affecting approximately 5% of school-age children (McEwan, 1998). The loss of control and thinking can be thought to be caused by some impaired brain functions that are important for children to maintain attention. The prefrontal cortex, caudate nucleus, and globus pallidus are three parts of the brain involved in the regulation of attention (Barkley, 1998).
