title: Quality of life in patients suffering from insomnia.
abstract: OBJECTIVE
  Systematic review of the literature pertaining to quality of life studies in adults suffering from insomnia, by specifically addressing the following questions: 1) What is the impact of insomnia on quality of life? 2) To what extent do comorbid conditions affect quality of life in patients with insomnia? 3) What is the impact of insomnia treatment on quality of life?
  
  
  METHODS
  Our search was conducted using the MEDLINE/PubMed and PsycINFO databases from the past 25 years (1987-2012), using the keywords "Insomnia" AND "Quality of Life," "QOL," "Health-related quality of life," or "HRQOL." Fifty-eight studies were selected for inclusion by two physicians who reached a consensus about the studies to include in this review.
  
  
  RESULTS
  The literature reveals that quality of life is severely impaired in individuals with insomnia, comorbid conditions significantly affects quality of life negatively, and sleep restoration techniques, including cognitive behavioral therapy and medications, are successful at improving quality of life. However, restoration of quality of life to community levels is still unclear.
  
  
  CONCLUSIONS
  Insomnia and its comorbidities negatively affect an individual's quality of life, and different modalities of treatment can produce improvements in physical and psychological wellbeing and quality of life. More research is needed to develop more interventions that specifically focus on improving quality of life in patients suffering from insomnia.
