Usually diagnosed in childhood, Asperger syndrome is a lifelong social disorder that bears many similarities to high-functioning autism. Individuals with the disorder are characterized by a lack of empathy, little ability to form friendships, one-sided conversations, clumsy movements, and intense absorption in special interests. While Asperger syndrome has received increasing attention from researchers, clinicians, educators, and parents in recent years, numerous central questions about the disorder remain unanswered. This groundbreaking volume brings together preeminent scholars and practitioners to offer a definitive statement of what is currently known about Asperger syndrome and to highlight promising leads in research and clinical practice. Diagnostic and conceptual issues are explored in depth, and the disorder's assessment, treatment, and neurobiology are thoroughly reviewed. The book examines the effects of Asperger syndrome on an individual's social, communication, and behavioral development, and identifies the challenges that these individuals face at home, in school and the workplace, and in other settings. The volume concludes with several parent essays that exemplify the trials and tribulations--as well as the joys and the and the victories --of life with a child with Asperger syndrome.
