ABSTRACT
This introduction presents an overview of key concepts discussed in the subsequent chapters of this book. The book illustrates the primary diagnostic feature of autism and Pervasive Developmental Disorder, not otherwise specified (PDD-NOS), and to introduce research that promotes early detection of various behavioral symptoms. It discusses the challenges that therapists face as they work with parents to determine whether or not their child has a serious developmental disorder. Common experiences among therapists include denial, sadness, and anger, as well as feelings of confusion when attempting to identify appropriate resources and tools for assessment. The book provides critical information about many of the movement and sensory related disorders experienced by children suffering from autism. A core diagnostic feature for children with autism is their apparent inability to play. It addresses some of the most important, emergent work in the field of autism, namely the development of various programs and therapies designed to increase child-driven social interaction and communication.
