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 - NCT05262543Recruiting
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.
Oggebbio, VerbaniaAges 18 years+ - NCT07829055Enrolling by invitation
Effects of mental tasks on breathing in chronic opioid users
This study looks at how doing mental tasks affects breathing in people who take opioids daily for chronic pain, compared to those with sleep apnea and healthy people. It may help understand how opioids affect breathing and improve safety.
San Diego, CaliforniaAges 45–65 - NCT07790744Recruiting
Brain imaging study for early Parkinson's signs in people with REM sleep disorder
This study uses MRI scans to look at the brain in people with REM sleep behavior disorder (RBD), a condition that can be an early sign of Parkinson's disease. By comparing them with healthy volunteers, researchers hope to find early markers of Parkinson's that could lead to earlier diagnosis and treatment.
HvidovreAges 18 years+ - NCT07735390Recruiting
