Brain structural changes in obstructive sleep apnea.
STUDY OBJECTIVES Determine whether obstructive sleep apnea (OSA) subjects show indications of axonal injury. DESIGN We assessed fiber integrity in OSA and control subjects with diffusion tensor imaging (DTI). We acquired four whole-brain DTI series from each subject. The four series were realigned, and the diffusion tensor calculated at each voxel. Fractional anisotropy (FA), a measure of fib...
متن کاملChanges in brain morphology associated with obstructive sleep apnea.
OBJECTIVE Obstructive sleep apnea (OSA) causes hypoxemia and fragmented sleep, which lead to neurocognitive deficits. We hypothesised that focal loss of cortical gray matter generally within areas associated with memory processing and learning and specifically within the hippocampus would occur in OSA. METHODS Voxel-based morphometry, an automated processing technique for magnetic resonance i...
متن کاملObstructive sleep apnea and the severity of coronary artery disease
Background: It has been implicated that obstructive sleep apnea (OSA) is associated with increased risk of cardiovascular disease including stroke, myocardial infarction, coronary artery disease (CAD) and hypertension. The aim of this study was to investigate the correlation between OSA and severity of atherosclerosis assessed by angiography. Methods: This study included 337 patients ...
متن کاملSleep Architecture in Patients With Primary Snoring and Obstructive Sleep Apnea
Introduction: This study aimed to investigate sleep architecture in patients with primary snoring and obstructive sleep apnea. Methods: In this study, we analyzed polysomnographic data of 391 clients who referred to Sleep Disorders Research Center (SDRS). These people were classified into three groups based on their Apnea-Hypopnea Index (AHI) and snoring; control, Primary Snoring (PS), and Obs...
متن کاملCardiovascular profile in patients with obstructive sleep apnea.
BACKGROUND Obstructive Sleep Apnea (OSA) is a risk factor for several cardiovascular conditions including increased cardiovascular mortality. It is therefore essential to know the major cardiovascular effects of sleep-disordered breathing during a clinical evaluation. OBJECTIVE To analyze the cardiovascular characteristics of patients with OSA. METHODS Patients underwent baseline polysomnog...
