As a clinician working with Autistic adults this book is a perfect addition to the resource library. It provides the reader with access to expert voices, providing an accessible appraisal of current literature, thinking and practical approaches in the complex and developing area of mental health and Autism. -- Dr Sue Smith, Head of National Autistic Society Lorna Wing Centre, and Highly Specialist Speech and Language Therapist This comprehensive and insightful volume will be essential reading for anyone working with adults on the autism spectrum. Dr Spain and her colleagues have collected authoritative chapters by leading clinicians and researchers, covering the many mental health issues affecting autistic adults, including anxiety, depression, OCD, and ADHD. Less well-known, but very important, conditions such as catatonia and PTSD are also covered, and every chapter provides practical as well as theoretical content. Appropriately, the final word is given to Joe Powell, who reflects on his own experience of striving for wellbeing as an adult on the autism spectrum. -- Francesca Happé, FBA FMedSci, Professor of Cognitive Neuroscience, Kings College London, Past-President of the International Society for Autism Research (INSAR)
