Differential Diagnosis of Autism Spectrum Disorder provides a framework for clinical considerations and best practices related to diagnosing children with autism spectrum disorder (ASD) versus commonly co-occurring conditions. Differential diagnosis is a complex process, and it is common for clinicians to observe symptom overlap between conditions. In this comprehensive text, the authors focus on the similarities and differences between ASD and a second diagnosis. Leading experts provide practical guidance in the diagnostic process for ASD versus a second condition, such as anxiety or attention deficit/hyperactivity disorder. Each chapter includes clinical case studies to provide real-world examples of how clinicians make diagnostic decisions. Ample illustrations and 'decision trees' provide a visual representation of clinical decision-making.

"In addition to a deep understanding of autism, a clinician must also have the skill and expertise to recognize a myriad of other possibilities to diagnose accurately. Is it autism, autism plus another disorder, or another disorder alone? This book clearly explains every major diagnostic differential and provides very practical guidance. It fills a critical gap for new and experienced clinicians and will become a necessary read for anyone in this field." - Stephen M. Kanne, Ph.D., ABPP (CN)
