This informative and easy to read book is an essential resource for parents, teachers, those new to the field, and people on the autism spectrum themselves. Diane Yapko, who has worked with individuals with Autism Spectrum Disorders and their families for over 20 years, brings together diverse information about the latest 'scientific break throughs', current developmental theories, and practical interventions around ASD. Her use of an accessible question and answer format enables her to address precisely those issues that are of most concern to people seeking introductory guidance or the information on the latest developments, and directions for further research. The book is organized into four main parts: diagnosis and characteristics; causes; medical issues; and treatments, intervention programs and approaches. The book's final part includes a useful listing of further resources.
