Attention Deficit Hyperactivity Disorder (ADHD)IntroductionAmong commonly diagnosed behavioral disorders, Attention Deficit Hyperactivity Disorder (ADHD) is the most widespread among young people and children. It is a persistent disorder attributed to neurobehavioral problems. Approximately 3-5% of all American children are affected by ADHD (NINDS Attention Deficit-Hyperactivity Disorder Information Page, 2011). The disorder is characterized by an inability to concentrate or concentrate on a task and to exert behavioral inhibition normally associated with age. There are several warning signs that may indicate the possibility that a child may be affected by this condition. These include difficulty following directions, talking a lot, disorganization, leaving homework or other tasks unfinished, and having difficulty paying attention to details or responding (Deficit Disorder Information Page of attention-hyperactivity of the NINDS, 2011). The fact that this disorder is considerably prevalent and costly has prompted research efforts to find approaches to the treatment and management of ADHD. Research into this mental illness has been largely inspired by discoveries regarding its physiological basis, which have paved the way for the discovery of therapeutic approaches. It is imperative that those caring for children with ADHD understand the diagnosis, prognosis, and phenomenology of ADHD in order to provide quality care to those affected (Sefa, 2007). In this article, the physiological bases as well as the symptoms of ADHD will be discussed. Additionally, the article will discuss a biological approach to treating ADHD and compare and contrast the genetic and environmental influences of the disorder. Finally, a summary of two articles in the middle of the article......nFrom the above discussion, ADHD is a mental illness that affects not only children but also adults. It is characterized by hyperactivity, impulsivity, disorganization and the inability to concentrate and complete tasks without distraction. To understand the physiological basis of ADHD, research has targeted notable neurobiological and neurochemical aberrations in people with ADHD. The use of psychostimulants in the treatment of ADHD changes brain function by improving attention through increased blood flow to areas of the frontal lobe. Current treatment trends emphasize the use of a multimodal approach to comprehensively address the complex nature of ADHD. It is clear from the discussion that ADHD is significantly influenced by genetic and environmental factors. Genetic research has focused on twin studies and family studies.
