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

CompletedPhase 1

Sponsor: University of California, San Diego

Conditions: OSA, Sleep Apnea, Obstructive Sleep Apnea, Alzheimer Disease

Interventions: Supplemental Oxygen, Continuous Positive Airway Pressure Machine, Room Air

Countries: United States

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.
