Cognitive Decline in Obstructive Sleep Apnea Linked to Perivascular Diffusivity

On August 11, a paper titled “Impact of Sleep Apnea on Perivascular Diffusivity and Cognition: A 4-Year Prospective Cohort Study” was published by Chang-Ho Yun from Seoul University in the Annals of the American Thoracic Society. The study found that obstructive sleep apnea (OSA) may lead to cognitive decline by affecting perivascular diffusivity (similar to … Read more

Evaluation of the Lymphatic System Function Using Diffusion Tensor Imaging Analysis Along the Perivascular Space (DTI-ALPS): A Cross-Vendor Test-Retest Validation

Abstract The method of Diffusion Tensor Imaging Analysis along the Perivascular Space (DTI-ALPS) aims to evaluate the function of the glymphatic system (GS). However, few studies have confirmed its reliability and reproducibility. DTI data from 50 participants from the MarkVCID consortium were included in this study. Two pipelines developed using DSI Studio and FSL software … Read more
