Symposium 11

Symposium 11： Sleep Apnea and Neurocognitive Dysfunction in Community Elderly

Obstructive sleep apnea (OSA) is characterized by recurrent episodes of partial or complete collapse of the upper airway during sleep, resulting in reduced (hypopnea) or absent (apnea) airflow lasting for at least 10 seconds and associated with either cortical arousal or a fall in blood oxygen saturation. OSA is present in approximately 25% of adults in the US and is a major cause of excessive sleepiness, contributing to reduced quality of life, impaired work performance, and increased motor vehicle crash risk. OSA is associated with an increased incidence of hypertension, type 2 diabetes mellitus, atrial fibrillation, heart failure, coronary heart disease, stroke, and death. OSA can be diagnosed with either home- or laboratory-based sleep testing, and effective treatments are available.Obstructive sleep apnea (OSA)may potentially be a modifiable risk factor for dementia. In this symposium, we will explore the prevalence and mechanism between OSA and Dementia.
