Sleep, Sleep Deprivation
Conditions
Brief summary
This study aims to investigate the effects of 24-hour acute sleep deprivation on plasma Alzheimer's disease biomarkers and multi-omics in individuals with different APOE genotypes, to elucidate the potential role of acute sleep deprivation in AD risk.
Detailed description
This is a randomized controlled trial designed to enroll 60 healthy volunteers. Stratified randomization will be used, with three strata defined by APOE genotype (APOE ε3/3, APOE ε4 carriers, and APOE ε2 carriers) in a 1:1:1 ratio. Within each stratum, participants will be randomly assigned in a 1:1 ratio to either the acute sleep-deprivation group or the non-acute sleep-deprivation group. The intervention will consist of 24 hours of acute sleep deprivation. The primary outcome measure is the change from baseline in plasma Aβ42 on the first day after randomization.
Interventions
Sleep deprivation for up to 24 hours with no naps or other sleep periods

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Plasma Aβ42 levels | 1 day after randomization |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Plasma GFAP levels | 1 day after randomization | — |
| Fatigue Scale-14 | 1 day after randomization | The Fatigue Scale-14 has a minimum score of 0 and a maximum score of 33; higher scores indicate greater fatigue severity. |
| Positive and Negative Affect Schedule | 1 day after randomization | The Positive and Negative Affect Schedule comprises two subscales: Positive Affect and Negative Affect. Each subscale ranges from 10 to 50, with higher scores indicating greater accumulation of the corresponding affect. |
| N-back tasks | 1 day after randomization | N-back test, participants are required to identify target digits that match the stimuli presented N steps earlier on the screen |
| Plasma Aβ40 levels | 1 day after randomization | — |
| Plasma t-tau levels | 1 day after randomization | — |
| Plasma p-tau181 levels | 1 day after randomization | — |
| Plasma p-tau217 levels | 1 day after randomization | — |
| Plasma NfL levels | 1 day after randomization | — |
| Plasma Aβ42/Aβ40 levels | 1 day after randomization | — |
| Plasma t-tau/Aβ42 levels | 1 day after randomization | — |
| Plasma p-tau181/Aβ42 levels | 1 day after randomization | — |
| Plasma p-tau217/Aβ42 levels | 1 day after randomization | — |
Other
| Measure | Time frame | Description |
|---|---|---|
| Metabolomics | 1 day after randomization | The plasma metabolomics will be determined by Liquid Chromatography - MassSpectrometry |
| Proteomics | 1 day after randomization | The plasma proteomics will be determined by Liquid Chromatography - MassSpectrometry |
| PET/MRI | 1 day after randomization | Assessed using Positron Emission Tomography/Magnetic Resonance Imaging(PET/MRI) |
