Brief Summary

Chronic sleep restriction is ubiquitous in both the general population and the military. The deleterious effects of sleep loss on human alertness and cognitive performance have been documented in numerous studies dating back to the nineteenth century. Over the past decade, evidence has emerged indicating that chronic sleep restriction may also precipitate deleterious, long lasting neuropathological changes in the brain. The purpose of this study is to determine neuropathological effects of sleep restriction and identify physiological mechanisms that correlate with sleep loss-induced performance impairment.

Outcome Measures

Primary Outcomes (1)

  • Positron Emission Tomography (PET) based measurement of neuroinflammation

    Positron Emission Tomography (PET) is the brain imaging method and \[11C\]ER176 is the PET radioligand providing an index of neuroinflammation

    3 Days

Secondary Outcomes (3)

  • Psychomotor Vigilance Task (PVT)

    55 Days

  • Actigraphy

    55 Days

  • Polysomnographic measurements of sleep and wakefulness

    19 Days

Interventions

Brain PET with \[11C\]ER176. \[11C\]ER176 is a PET ligand that images TSPO.
