Identifying autism spectrum disorder (ASD) as early as possible in a child's life can have a significant, positive impact on their journey to adaptation and independence. Yet very few diagnoses take place at an early, developmentally crucial stage. This unique visual guide aims to equip readers with the skills to recognise ASD in very young children. The book provides a systematic framework for understanding the complex nature of ASD. From social interaction to communication to repetition, each chapter focuses on a different area of development and uses photographs to illustrate and enhance understanding of presenting or absent behaviors. It is written in an accessible style and covers all of the core aspects of ASD, giving readers everything they need to be able to successfully identify the behavioral indicators of autism. A final chapter touches on options for seeking treatment after diagnosis. Taking a visual approach to identifying ASD in very young children, this book will be a valuable resource for early intervention professionals and students, occupational therapists, speech and language therapists, educational psychologists, paediatricians, teachers as well as parents of children pre- and post-diagnosis.
