A new study has used twin data to examine the longitudinal link between sleep problems and depression. Results of this study demonstrate that sleep problems predict later depression; the converse association was not found. These findings are consistent with the theory that early treatment of sleep problems may protect children from the development of depression.

Societal, Economic Burden Of Insomnia Is High
The indirect costs of untreated insomnia are significantly greater than the direct costs associated with its treatment. The study estimates that the total annual cost of insomnia in the province of Quebec is 6.5 billion Canadian dollars, representing about one percent of the province’s $228.5 billion in gross domestic product for 2002. The largest proportions of all insomnia-related expenses are attributed to lost job productivity, absences from work and alcohol used as a sleep aid.
