"What are the historical foundations of autism and what precisely is meant by the autistic spectrum? How can we explain behavioural patterns of people with autism, young or old, and what are the major theoretical bases for understanding these? What is the latest thinking in how people are diagnosed with autism, and what are the most effective strategies for assessment, education and care for people with this extraordinary disability?" "Charting the development of our understanding of the condition, this book guides readers through theories at the psychological, neurobiological and 'first cause' levels, to methods of care, intervention, education and support. Concerned with provoking a critical attitude, the author also identifies areas of doubt and controversy, suggesting how they might arise and ways in which they may be resolved."--Jacket.
