Maintenance treatment of insomnia: What can we learn from the depression literature?

Insomnia and depression are common problems with profound public health consequences. When left untreated, both conditions have high rates of persistence and recurrence. Maintenance treatment for depression is fairly well established, but there is no evidence-based consensus regarding the safety and efficacy of maintenance therapy for insomnia. Consequently, longterm treatment of insomnia is driven primarily by the individual choices of patients and their clinicians. This article compares and contrasts the current state of research in the maintenance therapy of depression and insomnia and highlights gaps in the insomnia literature.
