CPAP Therapy for Obstructive Sleep Apnea
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial aims to determine if using CPAP (a machine that aids nighttime breathing) along with online sleep education can improve memory and thinking in older adults with mild cognitive issues and untreated obstructive sleep apnea (a condition where breathing stops and starts during sleep). Participants are divided into two groups: one starts CPAP immediately, while the other begins after four months of sleep education, to assess if earlier CPAP initiation is more beneficial. This study targets adults over 55 with mild cognitive impairment and moderate to severe sleep apnea who have not received prior apnea treatment. As an unphased trial, it offers a unique opportunity to contribute to understanding how sleep treatments can enhance cognitive health.
Do I need to stop my current medications for the trial?
The trial does not specify if you need to stop taking your current medications, but it does exclude those taking disease-modifying agents for mild cognitive impairment.
What prior data suggests that CPAP therapy is safe for older adults with mild cognitive impairment and obstructive sleep apnea?
Research has shown that CPAP (Continuous Positive Airway Pressure) therapy is generally safe for individuals with obstructive sleep apnea (OSA). Studies indicate that CPAP use can enhance quality of life and reduce health risks associated with sleep apnea. For instance, one study found that regular CPAP use decreased excessive sleepiness and improved mental sharpness. Another study demonstrated that CPAP users had a lower risk of serious heart problems and even reduced death rates.
Regarding side effects, CPAP is usually well-tolerated. Some users might experience minor issues like a stuffy nose or discomfort from the mask, but these can often be managed by adjusting the equipment or settings.
CPAP is already widely used to treat sleep apnea, which supports its safety for this trial. Overall, evidence suggests that CPAP is a safe option with benefits that outweigh potential risks.12345Why are researchers excited about this trial?
Researchers are excited about the CPAP therapy trial for obstructive sleep apnea because it integrates personalized support and web-based sleep education, which sets it apart from conventional treatments. Traditional CPAP therapy often lacks the continuous, personalized guidance provided in this trial, where participants receive structured support from sleep technologists through calls and video sessions. Additionally, the inclusion of the Brain Health Pro platform offers a unique educational component aimed at increasing dementia awareness and promoting lifestyle changes to reduce dementia risk, a feature not typically included in standard sleep apnea treatments. This comprehensive approach not only targets sleep apnea but also addresses broader health concerns, making it a promising advancement over existing options.
What evidence suggests that CPAP therapy and web-based sleep education could be effective for improving cognitive function in older adults with mild cognitive impairment and obstructive sleep apnea?
Research has shown that CPAP (Continuous Positive Airway Pressure) therapy effectively treats obstructive sleep apnea (OSA). Studies have found that regular CPAP use significantly reduces symptoms like interrupted breathing during sleep and improves the quality of life for individuals with moderate to severe OSA. Additionally, regular CPAP use is linked to a lower risk of death and heart problems. Observational studies suggest that using CPAP for at least four hours each night reduces the risk of death compared to not using it. In this trial, participants in the Early CPAP group will receive a CPAP device at their baseline visit, while those in the Later CPAP group will receive the device after an initial period of web-based sleep education. These findings support the idea that CPAP can enhance sleep and overall health.12678
Are You a Good Fit for This Trial?
This trial is for older adults with mild cognitive impairment (MCI) and untreated obstructive sleep apnea (OSA). Participants will engage in web-based sleep education and undergo CPAP therapy to see if it improves cognitive function. The study excludes details on specific inclusion or exclusion criteria.Inclusion Criteria
Exclusion Criteria
Timeline for a Trial Participant
Screening
Participants are screened for eligibility to participate in the trial
Treatment
Participants receive CPAP therapy and web-based sleep education for 8 months in the Early CPAP group or 4 months of sleep education followed by 4 months of CPAP and sleep education in the Later CPAP group
Cognitive Assessment
Participants undergo cognitive assessments, provide blood samples, use wearable devices to measure sleep patterns and physiology, and complete MRI scans
Follow-up
Participants are monitored for safety and effectiveness after treatment
What Are the Treatments Tested in This Trial?
Interventions
- CPAP Therapy
- Web-Based Sleep Education
Trial Overview
The study tests whether CPAP combined with web-based sleep education can improve cognition in MCI patients more than just the education alone. It also examines if longer treatment duration (8 months vs. 4 months of CPAP) has additional benefits.

Experimental Treatment
Active Control
Participant will receive a study-provided CPAP device at their baseline visit, with settings set by one of the study sleep medicine physicians according to current clinical practice parameters. Participant will undergo an in-person mask fitting and then will be supported by a study sleep technologist with extensive clinical experience with CPAP who will contact the participant by telephone or video call at set intervals. Masks, tubing, chin straps, and other equipment necessary to optimize CPAP adherence will be provided by the study. Adherence will be monitored through downloads from the CPAP device. Participant will be asked to use CPAP nightly during their participation in this study. Participant will simultaneously participate in web-based sleep education through the Brain Health Pro (BHP) platform; a formal educational program designed to increase dementia literacy, foster engagement, and convey best available evidence for lifestyle changes that can mitigate dementia risk.
Participant will receive the web-based sleep educational intervention first for 4 months. Participant will then receive a study-supplied CPAP device with settings set by one of the study sleep medicine physicians according to current clinical practice parameters. Participant will undergo an in-person mask fitting and will be supported by a study sleep technologist with extensive clinical experience with CPAP who will contact the participant by telephone or video call at set intervals. Equipment necessary to optimize CPAP adherence will be provided. Adherence will be monitored through downloads from the CPAP device. Participant will be asked to use CPAP nightly throughout their participation. Participant will simultaneously participate in web-based sleep education through the Brain Health Pro platform; a formal educational program designed to increase dementia literacy, foster engagement and convey best available evidence for lifestyle changes that can mitigate dementia risk.
