Attention deficit hyperactivity disorder, or ADHD, is one of the most common developmental disorders. It is also one of the most controversial. Since the 1950s, when hyperactivity in children was first diagnosed, psychiatrists, educators, parents and politicians have debated the causes, treatment and implications of the disorder. Hyperactive: The Controversial History of ADHD is the first history of the disorder. Matthew Smith highlights the limitations of regarding ADHD as simply neurological, and contends that hyperactive children are also a product of their social, cultural, political and educational environment. Instead of simply accepting conventional understandings of ADHD, this book addresses the questions central to the emergence of the disorder: Why were children first diagnosed with the disorder? Why did biological explanations become predominant? Why did powerful drugs become the preferred treatment? And why have alternative explanations failed to achieve legitimacy?
