This important handbook presents the latest research and practical knowledge about a broad range of disorders with a genetic component that affect children's learning, behavior, and development. The book demonstrates the difference that well-planned interventions and accommodations can make in the health and functioning of children with mild to severe neurodevelopmental impairment. Chapters offer in-depth discussions of specific disorders, including learning disabilities, ADHD, Tourette syndrome, anxiety disorders, pervasive developmental disorders, and numerous less frequently encountered conditions. Current research on etiologies is reviewed, neurodevelopmental, psychosocial, and medical implications are considered, and practical suggestions are provided for assessment and clinical management.
