Abstract
This is a new and expanded edition of a classic case-study in the medicalization of ADHD, originally published in 1976. The book centres on an empirical study of the process of identifying hyperactive children, providing a perceptive and accessible introduction to the concepts and issues involved. In this revised edition, Peter Conrad sets the original study in context, demonstrating the continuing relevance of his research. He highlights the issues at stake, outlining recent changes in our understanding of ADHD and reviewing recent sociological research.
