This timely volume brings together well-established scholars and emerging voices to explore research methods and ethics in Neurodiversity Studies. It explores the epistemic injustice that currently surrounds much knowledge production around neurodivergence, and offers concrete examples of creative, participatory, and collaborative research practice in the field. The editors have assembled chapters combining reflexive, theoretical, and practical contributions. Together they address current debates surrounding participatory methods and Neurodiversity Studies and are unique in giving voice to mainly neurodivergent researchers and contributors across autism, ADHD, acquired brain injury, and multiple neurodivergence. The first of its kind, this much-needed volume contains essential reading for all those learning and teaching in the field of neurodiversity. It further represents a valuable resource for students and academics at all levels, participatory or creative researchers, research commissioners, and research evidence users across the social sciences.
