Water Exchange across the Blood‐Brain Barrier in Obstructive Sleep Apnea: An MRI Diffusion‐Weighted Pseudo‐Continuous Arterial Spin Labeling Study

Abstract

OSA subjects show compromised BBB function, but intact large artery integrity. The BBB alterations may introduce neural damage contributing to abnormal functions in OSA, and suggest a need to repair BBB function with strategies commonly used in other fields.
