Is Obstructive Sleep Apnea Important in the Development of Alzheimer's Disease?

University of California, San Diego·interventional·Posted Oct 26, 2021·Updated May 11, 2026

In Brief

A Phase 1 clinical trial evaluating Supplemental Oxygen, Continuous Positive Airway Pressure Machine, and 1 other intervention for OSA and 3 related conditions. Completed, enrolled 182 participants across 1 site.

Detailed Summary

Obstructive sleep apnea (OSA) is common in older adults and has recently been implicated in pathogenesis of Alzheimer's disease (AD). Research has shown that sleep disruptions have caused memory impairment. Sleep apnea is a form of sleep disruption. We would like to examine how obstructive sleep apnea may contribute to the progression of Alzheimer's disease.

Interventions

Supplemental Oxygenother

Subjects will be instrumented with a nasal cannula to receive 2L/min supplemental oxygen. The oxygen will be kept at a fixed rate, however, the participant will be titrated to receive a max of 4 liters per min to maintain sats \>90% based on oximetry readings.

Continuous Positive Airway Pressure Machinedevice

Continuous positive airway pressure is a form of positive airway pressure ventilation in which a constant level of pressure greater than atmospheric pressure is continuously applied to the upper respiratory tract of a person.

Room Airother

Subjects will be instrumented with a nasal cannula to receive 2L/min pressurized room air. The room air will be kept at a fixed rate, however, the participant will be titrated to receive a max of 4 liters per min to maintain sats \>90% based on oximetry readings.
