Homeostatic Regulation of Sleep in Short Sleepers
France75 participantsStarted 2026-04
Plain-language summary
This single-center study targets adults with distinct sleep profiles, divided into three categories: natural short sleepers, characterized by a reduced nocturnal sleep duration; subjects with idiopathic hypersomnia (IH) followed at the Sleep Disorders Unit of CHU Gui de Chauliac, with excessive daytime sleepiness; and control normal sleepers, with standard sleep duration and no specific complaints.
The aim of this study is to analyze the mechanisms of slow-wave regulation during sleep according to sleep phenotype (normal, short, and long sleepers/idiopathic hypersomnia) by examining the decay of EEG spectral power in the delta band over central regions during the first night of continuous 32-hour recording.

Inclusion criteria
Normal sleepers: Weekday sleep duration of between 7 and 8 hours, with weekend sleep duration generally similar or slightly longer (between 7 and 9 hours), reflecting a normal sleep duration without restriction or significant catch-up sleep, and with no complaints of daytime sleepiness (ESS \<10).
HI subjects, with increased sleep duration: Increased sleep need, with a reported sleep duration of ≥ 10 hours per night and \> 11 hours over a 24-hour period; increased sleep duration associated with excessive daytime sleepiness not explained by another sleep disorder.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

What they're measuring
1
The decrease in EEG spectral power in the delta band (0.5-4 Hz) over the central region during the first night of a continuous 32-hour recording.
