Insomnia

Insomnia, or sleeplessness, is an inability to fall sleep or to stay asleep as long as desired.[1] While the term is sometimes used in to describe a disorder demonstrated by polysomnographic evidence of disturbed sleep, insomnia is often practically defined as a positive response to either of two questions: "Do you experience difficulty sleeping?" or "Do you have difficulty falling or staying asleep?"[1]
