title = "Chronic insomnia: Current issues",
abstract = "Insomnia is a common problem in the general population and has a higher prevalence in persons withmedical and psychiatric disorders. Although insomnia is most often transient, occurring as a result of identifiable stressors, a substantial portion of insomnia cases involve persistent sleep difficulty. This chronic form of insomnia may be associated with a wide range of adverse consequences. An understanding of the characteristics and causes of this disorder and the available therapeutic strategies will promote more effective identification and treatment of patients with chronic insomnia.",

note = "Funding Information: Survey data suggest that insomnia is at least an occasional problem for about one third to one half of the adult population. The prevalence of chronic insomnia can be estimated from questionnaires that probe duration of insomnia symptoms and from longitudinal studies in which subjects are assessed at different time points. Ford and Kamerow I analyzed data from the Epidemiologic Catchment Area Study sponsored by the National Institutes of Health (NIH), which involved structured interviews of -8000 subjects. Insomnia was defined as a sleep disturbance persisting at least 2 weeks and had a prevalence of -10% in the general population. Ohayon and Roth 2 presented findings from detailed telephone interviews of nearly 15,000 subjects in 4 European countries. Approximately 19% of the population reported experiencing insomnia that was associated with impaired daytime functioning. Ninety percent of these insomnia subjects reported symptoms of at least 6 months' duration, and 41% reported having had insomnia symptoms for at least 10 years. Katz and McHorney 3,4 analyzed data from the Medical Outcomes Study, which surveyed outpatients with 1 or more chronic medical conditions. Of the 3445 patients interviewed, 34% reported mild symptoms and 16% reported severe symptoms of insomnia. When these patients were reinterviewed 2 years later, 59% of those with mild symptoms and 83% of those with severe symptoms continued to experience insomnia. This evidence shows that for many individuals, insomnia becomes a chronic condition.",
