This new theory in regards to ADHD (Attention-Deficit Hyperactivity Disorder) claims that the disorder results from a failure in self-control, key brain circuits do not develop properly, and maybe because of an altered gene(s). In the past researchers believed children to have some sort of brain damage. Well I would have to agree with today's new theory (stated above). Researchers today believe that it is "faulty" genetics, or non-genetics (premature birth, maternal alcohol, tobacco, and brain injuries), but more convincing is the brains use of dopamine. Dopamine is one of the chemicals used to convey messages between nerve cells, which then affect a person's movement, and emotion. This plays a big role in a child or any person(s) regular behavior. If a child cannot control his or hers emotions or movements it would be significantly clear that the child had some kind of disorder and that this child is hyper. In return not allowing the child to have much control over his/hers activities.
             I would have to agree with the author that the central deficit in ADHD is Self-control. Self-control is defined, as the capacity to inhibit or delay's one's initial motor responses to an event. The author speaks of children growing up and producing the ability to control one's thoughts, ADHD children have difficulty in this area. This concept in my opinion serves as being true. I have had the opportunity to see this first hand, my little cousin was diagnosed with ADHD a year ago he is now 7 years old and he displays all of the symptoms described in this new theory, especially the lack of self-control.
