Clinical Trial Summary

The purpose of this study is to change the concentration of amyloid-beta in human cerebrospinal fluid (CSF) through modulation of the sleep-wake cycle.


Description:

The purpose of this research study is to investigate whether or not increasing or decreasing duration of sleep over one night will change the concentration of amyloid-beta in cerebral spinal fluid (CSF).

Outcome

Type Measure Description Time frame Safety issue
Primary Percent Increase From Mean Baseline (07:00 to 19:00) of Cerebrospinal Fluid (CSF) Amyloid Beta During Sleep Induction and Sleep Deprivation Between 01:00 and 11:00 From Baseline Overnight (01:00 to 11:00) differences in CSF amyloid beta from baseline (07:00 to 19:00) between 1) sleep-deprived and control participants and 2) sleep-induced and control participants. Baseline = 07:00 to 19:00; Intervention period = 01:00 to 11:00
