What this study is about

Researchers are testing if successful treatment for Obstructive Sleep Apnea (OSA) improves memory and brain markers related to Alzheimer's disease in older adults. Participants with moderate-severe OSA will be randomly assigned to receive a treatment, such as an oral appliance or positional therapy, that effectively reduces their AHI (Apnea-Hypopnea Index) to below 10/hour for at least 3 months, or to a waitlist control group. The trial will follow participants for another 24 months on stable therapy to see if sustained improvements in sleep are linked to better cognitive function and brain markers.
