Attention Deficit Hyperactivity Disorder: Neurobiology of a Disorder or a Difference? Attention Deficit Hyperactivity Disorder (ADHD) is a phrase that has moved out of the realm of pure science or psychology and into common parlance. Like depression, the public has a general and vague sense of the "type" of person who may have ADHD, and has heard the name Ritalin, the main drug used in treatment, bandied about. As the name of the disorder implies, its symptoms present generally as "inattention and a combination of hyperactive and impulsive behaviors" (2). ADHD has only recently been able to be tangibly identified in the nervous system, and its' diagnostic criteria has continued to be revised. The discovery of specific physiological differences in the brain has enabled scientists to correlate the behavioral symptoms associated with ADHD with specific differences, mutations, or malfunctions in the brain. Though the scientific burden of proof cannot be ignored, the way in which we choose to define these differences as a "disorder" is debatable. Given both the scientific understanding of the sheer size of the nervous system and the more poetic notion of individuality, the neurobiological differences associated with ADHD are difficult to adequately define within the unlimited permutations of human personalities. The current official American criteria for diagnosing the condition of ADHD, according to the DSM-IV, is based on a child presenting at least six symptoms of inattention, hyperactivity-impulsivity, or both, that have persisted for at least six months (3). Additionally, some symptoms must have been present before seven years of age, and some type of social, academic or occupational impairment must result from these symp... ...//www.sciam.com/missing.cfm 3) DSM-IV diagnostic criteria http://www.mentalhealth.com/dis1/p21-ch01.html 4) fabulous paper by Bonnie Craymond linking ADHD and the creative personality http://borntoexplore.org/adhd.htm 5) article from "The Medical Post" by Harvey McConnell http://www.mentalhealth.com/mag1/p5m-add2.html 6) great graphic http://www.sciam.com/missing.cfm 7) pharmacology information on Ritalin http://www.mentalhealth.com/drug/p30-r03.html 8) list of myths and corrections about ADHD http://www.add.org/content/abc/myths.htm 9) article from "Time" by Claudia Wallis http://www.mentalhealth.com/mag1/p51-adhd.html 10)"Scientific American" article by Kristin Leutwyler http://www.mentalhealth.com/mag1/p51-adhd.html 11) part of Barkley article diagramming a psychological model of ADHD http://www.sciam.com/missing.cfm
