Insomnia and Daytime Functioning

Trial Objective

The purpose of this study is to learn more about people with primary insomnia and cognitive impairment. Primary insomnia is having difficulty falling asleep or staying asleep despite adequate opportunity for sleep, and your insomnia is not directly associated with any other health condition or problem. Cognitive impairment is difficulty with mental abilities such as thinking, knowing and remembering.

If you decided to participate in this study, you would be assigned to either the primary insomnia group or normal sleeper group based on your responses to our study questionnaires. You will then be asked to perform 2 consecutive nights of home sleep testing, followed by a daytime Multiple Sleep Latency Test (MSLT) at National Jewish Health’s Sleep Lab. The MSLT study is a daytime sleep study and includes a series of naps spaced about 2 hours apart from each other. We have you try to fall asleep during each nap in an effort to try and see how long it takes you to fall asleep. If you do fall asleep we will give you 20 minutes to sleep and look for a type of sleep called Rapid Eye Movement or REM sleep before we wake you up. In between the naps we will ask you to complete neuro-cognitive tests that will examine your memory and concentration. The MSLT testing will take place during the day at National Jewish Health and will last all day from 7am-5 pm.
