With the increased number of children being diagnosed with Autism Spectrum Disorders, parents and professionals are in search of materials that provide information theat will enable them to better understand affected children. While in the past individuals who were diagnosed had limited verbal and intellectual skills, newly diagnosed children often have good language skills and even areas of giftedness. This A-to-Z work contains original entries on the topic of Autism Spectrum Disorders. Entries include facts about disabilities, personal and historic perspectives, interventions, assessments, educational methods, trusted internet resources, and national organizations. The work outlines the contributions of founding researchers and other professionals and includes personal perspectives from individuals with ASD and their parents. It also includes lesson plans that can be implemented in a home, school, or community setting. No other such definitive resource exists that provides both educational and practical information related to ASD.
