MIBG heart scan study for aging and neurologic conditions
This Phase 4 study tests how an iodine-based heart scan (a special imaging test) works in people with certain neurologic diagnoses and aging-related conditions. It may help researchers better understand the heart-brain connection in these disorders and improve future care.
Rochester, MinnesotaAges 40–90 - NCT06727448Recruiting
Testing a new French sleep regularity questionnaire
This study is testing a new French questionnaire about sleep regularity. You will wear a small device (actimetry) for 14 days as part of your regular sleep check-up, and fill out the questionnaire to help doctors see if it's a good tool.
BordeauxAges 18 years+ - NCT06444256RecruitingPhase 2
Testing a sleep medication for people with stimulant use
This trial tests whether a medication that blocks a brain chemical involved in wakefulness can help people with stimulant use disorder sleep better. If you use cocaine or methamphetamine and have trouble sleeping, this study may be an option.
Houston, TexasAges 18–65 - NCT07509125Recruiting
Ultra-high resolution PET brain scans for aging, dementia, and psychosis
This study uses a new ultra-high resolution PET scanner to look at brain changes in healthy aging, dementia, ALS, movement disorders, and psychosis. It aims to better understand these conditions and improve imaging techniques.
Leuven, Vlaams-BrabantAges 18–90 - NCT06810180Recruiting
Sleep, activity, and daily rhythms in ADHD
This study looks at how sleep, physical activity, and daily rhythms affect thinking and behavior in people with ADHD. It may help find ways to improve symptoms through better sleep and activity habits.
Baltimore, MarylandAges 8–12 - NCT05826457Enrolling by invitation
Study for early RBD as a possible Parkinson’s risk
This study looks at people with REM sleep behavior disorder (RBD), confirmed by a sleep test, who may be in the early “prodromal” stage before Parkinson’s or related diseases. It also enrolls healthy controls to compare results from brain and body testing to better understand who is at risk.
Los Angeles, CaliforniaAges 18 years+ - NCT03623672Enrolling by invitation
Study for early signs of Parkinson-related brain changes
This study enrolls people with idiopathic REM sleep behavior disorder, a sleep problem that can come before Parkinson’s disease or related conditions. It aims to better understand early (“prodromal”) changes so future treatments can be targeted earlier.
Sun City, ArizonaAges 18 years+ - NCT07667309Recruiting
Nerve block effects on sleep in PTSD therapy
This study looks at whether a nerve block (stellate ganglion block) can improve sleep for military members and veterans with PTSD who are already getting a type of talk therapy. You'll wear a special headband to track your sleep patterns overnight.
Killeen, TexasAges 18–65 - NCT07735390Recruiting
Chinese Herbal Medicine for Insomnia: A Pilot Study
This trial tests whether two traditional Chinese herbal formulas can help improve sleep in people with chronic insomnia. If you have trouble sleeping and are open to herbal treatment, this study may be an option.
TainanAges 20 years+ - NCT07052357Enrolling by invitation
Intern health study 2025

Study predicts risk of RBD turning into Parkinson’s
This study looks at people diagnosed with idiopathic REM sleep behavior disorder (a sleep problem where you act out dreams) and tries to predict who may later develop another condition related to Parkinson’s. If you qualify and consent, you may be followed to understand risk factors and improve early identification.

Brain training study in people with REM sleep behavior disorder
This study looks at how the brain changes (“neuroplasticity”) in people diagnosed with isolated REM sleep behavior disorder (iRBD) using brain stimulation and other testing. Results may help researchers understand brain differences in iRBD and guide future treatments.
Minneapolis, MinnesotaAges 21–75 - NCT05721911Recruiting
Study using brain-cell tests to better understand Parkinson’s risk
This study collects blood and related samples to create a “biobank” and uses lab tests to study genetic risk in Parkinson’s disease and idiopathic REM sleep behavior disorder (RBD). It may help researchers understand why symptoms develop and improve future prevention or treatment approaches.

Common questions
- Are there clinical trials for sleep disorder?
- Yes. Clin2 currently lists 263 recruiting sleep disorder studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a sleep disorder trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a sleep disorder trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
