This book is an accessible primer focused on the provision of neuro-affirming clinical care for autistic clients, written from the perspective of autistic clinicians. In eight chapters, this book provides actionable steps without the assumption of expert autism knowledge. It first builds foundational knowledge for understanding what autism is and how to talk about it using current language practices. This book then explains how to recognize and assess for autism, alongside overviewing co-occurring mental health concerns among this population. This book also includes strategies for effective communication and interventions with autistic individuals, supporting autistic individuals day-to-day, and maintaining ethical clinical practices. Broadening beyond individual clients, this book additionally outlines strategies for supporting families and caregivers of autistic individuals, with an emphasis on the importance of understanding the impact that autism may have on family dynamics. This book is the answer for clinicians asking themselves how they can better serve their autistic clients.
