Deutsch: Der Begriff Schlafstörung (Syn.: Agrypnie, sowie In- und Hyposomnie) bezeichnet Beeinträchtigungen der Schlafes aus unterschiedlichen Gründen.
English: Insomnia (or sleeplessness) is most often defined by an individual's report of sleeping difficulties. While the term is sometimes used in sleep literature to describe a disorder demonstrated by polysomnographic evidence of disturbed sleep, insomnia is often defined as a positive response to either of two questions: "Do you experience difficulty sleeping?" or "Do you have difficulty falling or staying asleep?"
