For the first time, this book presents a detailed account of the topic of insomnia in German, based on extensive data material. It serves as a guide and reference for (specialist) physicians and psychologists who treat patients with sleep disorders or need to assess related limitations in daily well-being. Both pharmacological and non-pharmacological treatment methods for insomnia are thoroughly discussed. Particularly important for the practicing physician: a content overview for each chapter, summaries in lists, tables, and diagrams; numerous pragmatic recommendations; and an index.
