The North American Perspective On Attention Deficit Hyperactivity Disorder

The purpose of the present paper is to (1) provide an overview of the nature of attention-deficit hyperactivity disorder (ADHD) as it seems to be viewed by North American clinicians and clinical scientists; (2) describe its diagnostic criteria as they are applied in that region; (3) discuss the prevalence of ADHD in the region; and (4) briefly present a new theoretical model of the authors emerging from that North American perspective. Some of the critical issues related to these matters will be raised along the way. Given the thousands of scientific papers on this topic, however, an overview of these various topics is all that space here can afford. Readers wishing a more thorough treatment of these topics as well as those pertaining to history, developmental courses, associated risks, assessment, and treatments for ADHD are directed to other writings by the author (Barkley, 1990).
