Book excerpt: "What is autism and Asperger syndrome? What are the core symptoms, and what causes them? How early can autism be recognised and what can be done? Why does autism seem to be more and more common? Are we all a little bit autistic?" "This Very Short Introduction offers a clear statement on what is currently known about autism and Asperger syndrome. Looking at symptoms from the full spectrum of autistic disorders, and evaluating current evidence from neuroscience and genetics, this authoritative and accessible book explores the source and nature of social impairment and exceptional talent. Autism: A Very Short Introduction gives a glimpse of life seen through the eyes of autism."--BOOK JACKET.
