Edited by two leading authorities and written by a team of international experts in the field, this book describes the causes, course and treatment of a variety of developmental and genetic disorders, including attention-deficit disorder, fragile X syndrome and the autistic spectrum disorders. There is a particular focus on the course of disorders over time, and outcome in adulthood. Outcome is an area often overlooked in other books about developmental disorders, but is an issue of great importance to parents and carers and one that has important implications for education, health, social and employment services. As well as providing succinct and up-to-date summaries of the most recent research, the authors give clinicians practical guidelines for intervention and management with children and young adults. This book is essential reading for clinicians and psychologists, and anyone working with or caring for children with special educational needs.
