Why This Book Matters

Dissociative disorders—such as dissociative identity disorder, depersonalization/derealization disorder, and other specified dissociative disorders—are often misunderstood and underdiagnosed. This book aims to bridge the gap between historical conceptualizations and modern evidence-based approaches. It provides a thorough overview of the evolution of dissociation as a concept, from its early descriptions by pioneers like Pierre Janet to contemporary neurobiological and cognitive models. By integrating past and present knowledge, the book helps clinicians and researchers appreciate the complexity of dissociation and its impact on individuals across cultures. In the Canadian context, where mental health services are incregly trauma-informed, this resource is particularly valuable.
