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.

Primary Insomnia

Study Type: Observational
Study Design: Observational Model: Case Control
Time Perspective: Cross-Sectional
Official Title: Metabolomics of Insomnia-Related Hyperarousal

Further study details as provided by University of Pennsylvania:

Primary Outcome Measures:
  • Metabolite profile [ Time Frame: 48 hours ] [ Designated as safety issue: No ]
    Metabolomics analysis of blood samples will be carried out using Spectroscopy. This approach allows for rapid, unbiased and quantitative metabolic profiles ('fingerprints) to be acquired. Metabolite profiles of individuals with insomnia will be compared to those of good sleepers.

Secondary Outcome Measures:
  • Sleep patterns [ Time Frame: 1 night ] [ Designated as safety issue: No ]
    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.

Estimated Enrollment: 30
