Abstract
Purpose: The association between sleep apnea syndrome (SAS) severity and white matter hyperintensities (WMHs) has been previously described. However, the associated anatomical details of WMHs remain unclear. The WMHs were divided into periventricular hyperintensity (PVH) and deep and subcortical white matter hyperintensity (DWMH). PVH is characterized as a non-vascular entity, whereas DWMH is vascular in nature. This study aimed to clarify the association between SAS and the anatomical details of WMHs.
Methods: Patients (n = 237) diagnosed with neurologically asymptomatic SAS (1999-2016) were enrolled. Any symptomatic SAS patients, whose MRI was conducted more than six months prior to SAS diagnosis, or whose data were incomplete were excluded. For patients with multiple MRI scans, the most recent imaging was employed. SAS diagnosis was defined as an apnea-hypopnea index (AHI) ≥ 5. PVH and DWMH were graded from 0 to IV according to severity. Age, sex, medical history, body mass index, AHI, estimated duration of SAS, and MRI findings were collected. Factors associated with PVH and DWMH grade ≥ I were analyzed.
Results: PVH grade ≥ I was associated with the estimated duration of SAS (odds ratio, 1.01; 95% confidence interval, 1.00-1.02), DWMH grade ≥ I (102.04; 21.40-486.49), hypertension (4.05; 1.53-10.74), and cerebral atrophy (17.47; 1.36-225.28). Age (1.07; 1.03-1.12) and PVH grade ≥ I (88.73; 19.07-412.86) were significantly associated with DWMH grade ≥ I.
Conclusion: This study confirmed that PVH rather than DWMH is associated with SAS. This study may contribute to research on the mechanism of WMHs caused by SAS.
期刊介绍：
The journal Sleep and Breathing aims to reflect the state of the art in the international science and practice of sleep medicine. The journal is based on the recognition that management of sleep disorders requires a multi-disciplinary approach and diverse perspectives. The initial focus of Sleep and Breathing is on timely and original studies that collect, intervene, or otherwise inform all clinicians and scientists in medicine, dentistry and oral surgery, otolaryngology, and epidemiology on the management of the upper airway during sleep.
Furthermore, Sleep and Breathing endeavors to bring readers cutting edge information about all evolving aspects of common sleep disorders or disruptions, such as insomnia and shift work. The journal includes not only patient studies, but also studies that emphasize the principles of physiology and pathophysiology or illustrate potentially novel approaches to diagnosis and treatment. In addition, the journal features articles that describe patient-oriented and cost-benefit health outcomes research. Thus, with peer review by an international Editorial Board and prompt English-language publication, Sleep and Breathing provides rapid dissemination of clinical and clinically related scientific information. But it also does more: it is dedicated to making the most important developments in sleep disordered breathing easily accessible to clinicians who are treating sleep apnea by presenting well-chosen, well-written, and highly organized information that is useful for patient care.
