Insomnia is a prominent complaint in late-life. However, little scientific effort has been directed toward identifying the biological mechanisms that are related to abnormal sleep or to evaluating the efficacy of behavioral treatments for insomnia in older adults. Basic observations demonstrate that proinflammatory cytokines play a key role in the regulation of sleep. Previous research shows that cytokines are reciprocally linked with abnormal sleep. This trial builds upon these findings and extends a program of study that has examined the efficacy of behavioral interventions on health outcomes in the elderly.
