NCT ID NCT06484348
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at how eating affects sleepiness and nighttime sleep in people with type 1 narcolepsy, idiopathic hypersomnia, and healthy volunteers. Over 4 days, participants will log their meals, wear a glucose monitor, and track sleep with a headband and watch. The goal is to understand why many people with narcolepsy are overweight and whether certain foods make sleepiness worse.
