Brief Summary:
The primary purpose of this study is to explore the underlying mechanisms that link sleep to Alzheimer's disease (AD), with special focus on the clearance of metabolites in the extracellular space of the brain during sleep. Subjects will wear an actigraph for 1 week to determine regular daytime activity and sleep patterns. Subjects will then undergo partial sleep deprivation followed by 4 hours of in-lab nocturnal polysomnography (NPSG). Participants will be be asked to stay awake and active all day after the partial sleep deprivation with a new actigraphy secured by a hospital band to assure participants remain awake. They will seep inside an MRI machine for 90 minutes on the following night during their usual bedtime (established by 1 week actigraphy study.) Morphologic imaging, flow imaging and diffusion kurtosis imaging (DKI) will be performed on a 3T Siemens scanner.

Arm Intervention/treatment
Experimental: Sleep Deprivation followed by Normal Sleep
Subjects will be sleep deprived at the sleep laboratory.
Device: Actigraph
Participants will be asked to wear an actigraph

Primary Outcome Measures :
  1. Measure of Interstitial Space Volume during sleep using MRI imaging [ Time Frame: 6 Months ]
    Data will be acquired using imaging sequences that comply with federal limits regarding radiofrequency energy deposition and gradient slew rates.

Secondary Outcome Measures :
  1. Changes in Cerebral Spinal Fluid volume measured by increases in the power of slow wave activity (SWA) [ Time Frame: 6 Months ]
    Data will be acquired using imaging sequences that comply with federal limits regarding radiofrequency energy deposition and gradient slew rates.

  • Significant history of alcoholism or drug abuse.
  • Inability to avoid the use of alcohol or caffeine during the 48h before the MRI.
  • Current pregnancy or intent to become pregnant during the period of study.
  • Any electronic or ferromagnetic devices (e.g., pacemaker or surgical clips) that constitutes a hazard for MRI imaging.
  • Any medications adversely affecting cognition, blood pressure, glucose metabolism, or sleep will result in exclusion.
