Radar could replace wires for narcolepsy sleep tests
NCT ID NCT07654803
First seen Jun 27, 2026 · Last updated Jul 22, 2026 · Updated 2 times
Summary
This study tests whether a millimeter-wave radar system can accurately diagnose type 1 narcolepsy by monitoring sleep without physical contact. Forty patients will use the radar alongside standard sleep tests (PSG/MSLT) to see if the radar matches the standard results. If it works, this could make narcolepsy diagnosis easier and more accessible, possibly even at home.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- millimeter-wave radar sleep monitoring system
- What this could lead to
- If successful, this could provide a simpler, non-contact way to diagnose narcolepsy, possibly allowing home-based sleep monitoring instead of hospital stays.
- What could go wrong
- This is a small, early feasibility study with only 40 participants, so results may not apply broadly. The radar system may not match the accuracy of standard tests.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: 1. Diagnosed by a doctor with type 1 narcolepsy； 2. Can complete two sleep tests: one full night (7 hours in bed) and daytime nap tests the next day (about 10 hours total)； 3. Agree to have a small radar device placed near the bed to record sleep alongside the regular tests, and keep it on throughout； 4. Medical records are complete and available； 5. You (and your parent/guardian if under 18) agree and sign the consent form. Exclusion Criteria: 1. Not willing to sign the consent form； 2. Have irregular sleep hours (e.g., night shifts, recent travel across time zones) or cannot follow the testing schedule to complete all tests； 3. Toss and turn too much, get out of bed often, or have too much interference around, causing the radar device to lose signals or record poor-quality data that cannot be analyzed.
