A person with chronic insomnia, or long-term insomnia, has difficulty sleeping at least three nights a week for one month or longer. Certain factors seem to make individuals more likely to experience this condition. Examples of these risk factors include advanced age (chronic insomnia occurs more frequently in those over age 60), being female, and having a history of depression. Treatment options for chronic insomnia typically include treatment of any underlying problems that may be causing it, medication, and certain behavioral techniques.
