Identifying Autism Spectrum Disorder (ASD) as early as possible can have a significant, positive impact on the child’s journey to adaptation and independence. Yet too 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 children as young as 15-18 months old. The book provides a systematic framework for understanding the complex nature of ASD. From social interaction to communication to restricted and repetitive behaviors, each chapter focuses on key symptoms 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 provides an overview of assessment options for young children being evaluated for possible ASD. 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, psychologists, paediatricians, teachers as well as parents of children pre- and post-diagnosis.
