Abstract：

Insomnia and obstructive sleep apnea (OSA) are the two most common sleep disorders. They each lead to increased health risks, lower quality of life, and significant economic costs. Only recently it has been discovered that the two disorders occur together very frequently with even more negative impact on health. This co-morbidity, however, presents treatment challenges because having insomnia deters patients from the common PAP therapies of sleep apnea. Our research has found that the insomnia component could be treated effectively with cognitive/behavior non-drug therapy. Importantly, the group whose insomnia was treated then showed greater acceptance of the PAP therapy and some of the benefits of that therapy. The results recommend the prior treatment of the insomnia component of this co-morbid sleep disorder. These findings should alert the medical profession to the common overlap of these two disorders and improve diagnostic and treatment practice of sleep disorders.
