SLEEP APNEA

This study looks at whether treating obstructive sleep apnea with a CPAP machine, starting soon after a stroke, can lower the chance of having another stroke, a heart attack, or dying within 6 months. Over 3,000 people who had a stroke are taking part. The goal is to see if sleep…

This study looks at whether showing sleep apnea patients how their CPAP machine use compares to other patients helps them use it more regularly. About 186 adults who have been on CPAP for at least three months will be split into two groups: one gets only their own usage data, the…

This study checks if a Withings smartwatch can accurately detect sleep apnea by measuring movement, heart rate, breathing, and blood oxygen. About 220 adults who are already scheduled for a hospital sleep test will wear the watch overnight. The goal is to see if the watch can rep…

This study looks at whether adding CPAP (a machine that helps you breathe during sleep) to a lifestyle program can improve blood sugar and blood pressure more than lifestyle changes alone. Researchers are studying 174 overweight or obese adults with prediabetes and sleep apnea. T…

This study tests three different drugs—sivopixant, acetazolamide, and SASS-001—to see if they can reduce breathing pauses during sleep in adults with sleep apnea that involves a central (brain-related) component. About 60 participants with stable heart failure or persistent atria…

This study was planned to test a new wearable wireless device that monitors central sleep apnea (pauses in breathing) in infants and children up to 5 years old. The device would be worn around the abdomen overnight alongside standard sensors to see how accurate and acceptable it …

This study looks at 100 adults with sleep bruxism (teeth grinding during sleep) to understand how it relates to sleep quality, heart health, thyroid function, and mental well-being. Participants will undergo sleep monitoring and fill out questionnaires. No treatment is given; the…

This study looks at how age-related sleep changes and sleep apnea might increase the risk of Alzheimer's disease in healthy older adults. Researchers will monitor 158 people aged 55-75 with normal thinking skills using sleep tests and brain scans over two years. The goal is to fi…

This study looks at how sleep apnea might cause prediabetes in overweight or obese adults. Researchers will measure stress hormones in the blood to understand the connection. The goal is to learn more about why people with sleep apnea are at higher risk for diabetes.

This observational study collects blood, urine, and tissue samples from 500 obese adults to learn more about obesity, weight loss, and why some people regain weight after treatment. Participants must be over 18 and have a BMI of 30 or higher. The samples will be stored for up to …

This study looks at whether dopamine levels and certain genes are linked to sleep breathing disorders like sleep apnea. About 100 adults with suspected sleep issues will have an overnight sleep test and a blood draw. The goal is to better understand what causes these conditions, …

This study uses a 30-40 minute online survey to understand sleep patterns, knowledge, and challenges among 1,000 medical trainees (students, residents, fellows) who work on-call shifts. The survey asks about sleep routines, daytime sleepiness, and insomnia symptoms. The goal is t…

This study looks at how sleep problems like apnea, insomnia, and poor sleep quality are linked to heart disease and diabetes in rural areas of the southern U.S. About 3,680 adults already part of a larger health study will wear sleep trackers and answer questionnaires. The goal i…
