静息态功能磁共振评价阻塞性睡眠呼吸暂停患者认知功能的研究进展

阻塞性睡眠呼吸暂停(obstructive sleep apnea，OSA)患者由于长期间歇性低氧、高碳酸血症以及睡眠结构紊乱，常伴有注意力、警觉性、长期视觉记忆和言语记忆、视觉空间/结构能力以及执行功能等认知功能改变。近些年来，静息态功能磁共振，特别是基于体素形态测量学、扩散张量成像、磁共振波谱和功能性磁共振成像等OSA患者存在显著的脑结构、代谢和功能改变，与认知功能评价量表反映的认知功能改变存在着密切关联，对研究OSA患者认知功能改变机制具有十分重要的意义，对OSA的早期诊治以及临床疗效评价有所帮助。

Progress in the evaluation of cognitive function in with obstructive sleep apnea by resting functional magnetic resonance

Obstructive sleep apnea is often accompanied by functional changes in attention, alertness, long-term vision and language memory, visual space/structural competence, and executive function due to long-term intermittent hypoxia, high blood carbonate, and sleep structure disorders. In recent years, some scholars have found that the changes of brain structure, metabolism and function revealed by static functional magnetic resonance imaging (MRI) are closely related to the changes of cognitive function reflected in the cognitive function evaluation scale. In recent years, static functional magnetic resonance, especially voxel-based morphometry, diffusion tensor imaging, magnetic resonance spectroscopy and functional magnetic resonance imaging have confirmed significant changes in brain structure, metabolism and function in OSA patients, and the changes are closely related to the changes of cognitive function reflected in the cognitive function evaluation scale. It is great significance to study the mechanism of cognitive function change in OSA patients, and helpful to the early diagnosis and treatment as well as the evaluation of clinical efficacy.
