Brief Summary

About 10% of the population is believed to suffer from Primary Insomnia. It is also believed that people with chronic insomnia have a sleep system that is essentially out of alignment (we call this "homeostatic dysregulation"). We also know that a certain form of non-medication therapy called cognitive-behavioral therapy is a very effective treatment for insomnia. It is not known, however, whether cognitive-behavioral therapy actually works by bringing the brain's sleep system back into alignment ("sleep homeostasis"). One of the methods used to measure sleep homeostasis is to observe a person's brain waves during sleep and particularly during sleep that follows a period of sleep loss. The purposes of this study are to first learn whether persons with insomnia do have a misaligned sleep system compared to persons who do not have insomnia by assessing the sleep of people before and after a period of extended sleep loss. Second, the study will determine whether cognitive-behavioral therapy can re-regulate the sleep system and its response to sleep loss. Third, the final purpose is to examine whether the immune system of people with insomnia is more altered following sleep loss than in the comparison group and whether cognitive-behavioral therapy can alter immune function.
