Metabolomics of Insomnia-Related Hyperarousal

N/ACompletedNCT01957111

University of Pennsylvania32 enrolled

Overview

Individuals with insomnia have been shown to have higher overall metabolic rates compared to good sleepers, but it is not known which metabolic processes are involved. The goal of this study is to compare a wide array of metabolic processes in 15 people with insomnia and 15 good sleepers. We hypothesize that there will be distinct metabolic processes that are functioning differently in those with insomnia.

Outcomes

Primary Outcomes

Number of Metabolites Elevated Relative to the Other Group.

Metabolomics analysis of blood samples were carried out using Spectroscopy. This approach allows for rapid, unbiased and quantitative metabolic profiles ('fingerprints) to be acquired. A total of 70 metabolites were measured and compared between individuals with insomnia and good sleepers.

Time frame: 48 hours

Secondary Outcomes

Sleep Efficiency Percentage on Overnight Sleep Study

Participants will have their sleep measured with polysomnography for one night. The sleep of individuals with insomnia will be compared to that of good sleepers. Sleep quality is defined as sleep efficiency, which is calculated at total sleep time / total time spent in bed x 100. It indicates the % of time spent asleep while in bed.

Time frame: 1 night
