Supporting Autistic Individuals During Crises presents a first-person exploration of living with autism while experiencing a mental health crisis, offering mental health professionals, individuals with lived experience and their families with guidance for providing effective support. Elevating voices of individuals with lived experience, this book examines how differences in sensory processing, communication, emotional regulation, and cognition shape the experience of psychological distress and crisis. Chapters examine the intersection between autism and mental health, grounding psychological theory in real life experience through detailed personal narrative and reflective analysis. Sensory overload, masking, burnout, shutdowns and meltdowns, disrupted routines and communication barriers are clearly explained, illustrating how these factors can intensify distress and delay access to support. Psychological safety is centred throughout, highlighting how calm environments, predictable responses, validation and capacity-based expectations reduce escalation and support recovery. Readers are encouraged to challenge common misconceptions about autism and will gain a wealth of practical strategies for support, highlighting the importance of autism-informed crises care and professional intervention. Presenting autism not as a deficit, but as a neurodevelopmental difference, this book provides essential recognition and reassurance to autistic readers. It is also essential reading for individuals supporting autistic individuals, such as family members, carers, mental health clinicians, educators, support workers and policymakers who are seeking to better understand autistic mental health and prioritise psychological safety.
