NCT02884505

Brief Summary

The overall purpose of this study is to employ a pragmatic, multidimensional assessment of hypersomnolence that "piggybacks" on routine clinical care in patients with suspected disorders of central nervous system (CNS) hypersomnia, to determine whether these additional objective and subjective assessments are useful in the diagnosis and management of these patients.

Outcome Measures

Primary Outcomes (1)

  • Proportion of Patients Categorized with Hypersomnolence

    Multiple measurements will be aggregated to arrive at the primary outcome of proportion of patients categorized as having hypersomnolence using either standard assessments or standard assessments plus additional novel hypersomnolence measures of pupillometry, psychomotor vigilance task, and auditory evoked potentials. Proportion of patients with hypersomnolence using standard measures will be calculated as number of patients with mean sleep latency (MSL) on multiple sleep latency test (MSLT) \<8 minutes divided by total number of patients. Proportion of patients categorized as having hypersomnolence with additional novel hypersomnolence measures will be calculated as the number of patients with MSL\<8 minutes, and/or pupillary unrest index (PUI) \>8.9 on pupillometry, and/or PVT lapses \>3, and/or P300 delay/sleep negativity during auditory evoked potentials divided by total number of patients.

Study Population

Patients referred for polysomnography and multiple sleep latency test at the University of Wisconsin-Madison

You may qualify if:

  • Age 18-89
  • Referred for polysomnography/multiple sleep latency test at Wisconsin Sleep, the sleep medicine clinic and laboratory of the University of Wisconsin-Madison

You may not qualify if:

  • unstable medical condition that, in the opinion of the investigators, would make it unsafe for the subject to participate
