"Attention deficit hyperactivity disorder, or ADHD, is one of the most common developmental disorders, with an average of 9 per cent of children between the ages of five and seventeen diagnosed each year. 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. Why and how were children first diagnosed with this disorder? Hyperactive provides the first history of ADHD, explaining why biological explanations became predominant; how powerful drugs became the preferred treatment; why diagnosis rates and treatments vary so widely around the world; and why alternative explanations have failed to achieve any legitimacy. Contending that hyperactive children are also a product of their social, cultural, and educational environment, Matthew Smith demonstrates how knowledge about the rise of ADHD can lead to better choices about its diagnosis and treatment. A revealing and accessible study of this hugely controversial subject, Hyperactive is an essential book for psychologists, teachers, policymakers and parents."--Jacket.
