Escape from one's own consciousness. Dissociative consciousness disorders are a highly relevant topic that has gained significance in recent years, particularly through trauma research, and has rapidly evolved. The fundamentally revised second edition of the handbook provides a comprehensive overview of the current state of theory, clinical practice, and therapy. The book introduces the neurobiological and cognitive psychological foundations of altered states of consciousness. It explains etiological models as well as issues related to diagnostics, differential diagnostics, and classification. Various disorder patterns, such as amnesias, depersonalization, dissociative seizures, fugue, trance states, and dissociative identity disorder are presented in detail. The editors emphasize current therapeutic approaches and an integrative understanding that encompasses both psychodynamic and cognitive psychological approaches.
