Glymphatic dysfunction across sleep disorders: a meta-analysis of DTI-ALPS studies. [PDF]
Background Sleep disorders are increasingly linked to glymphatic dysfunction, but whether this impairment is universal across different sleep pathologies remains unclear. Objective This meta-analysis examined whether glymphatic ...

Vascular drivers of cerebrospinal fluid movement and enlarged perivascular spaces
Abstract Perivascular spaces (PVSs) facilitate cerebrospinal fluid flow and waste clearance, which are critical for maintaining brain homeostasis. Enlarged PVSs (ePVSs) are an emerging marker of cerebral small vessel disease and are implicated in protein accumulation, neurodegeneration, and cognitive decline.

BackgroundThe glymphatic system plays a critical role in clearing interstitial waste from the brain. Dysfunction of this system has been linked to various neurodegenerative diseases, including amyotrophic lateral sclerosis (ALS).

Abstract INTRODUCTION We evaluated a multimodal magnetic resonance imaging (MRI)‐derived glymphatic‐related composite and examined its associations with cardiovascular risk, brain structural integrity, and cognition in older adults. METHODS Ninety‐two participants were included in the baseline analyses and 68 in the 6‐month reassessment analyses ...

DTI-ALPS index decreased in patients with Type 2 Diabetes Mellitus
BackgroundsType 2 Diabetes Mellitus (T2DM) has become a significant global public health issue, characterized by a rising prevalence and associated deficits across multiple organ systems. Our study aims to utilize the DTI-ALPS technique to assess the change of ALPS index in T2DM patients, and to explore whether such changes are correlated with ...

In patients with intracerebral hemorrhage, higher free water fraction in contralateral white matter was associated with lower odds of functional independence and greater WMH burden. These associations did not remain statistically significant after FDR correction, and the FW–outcome association was nonsignificant after adjustment for WMH burden ...

Orientation-Aware Refinement of the DTI-ALPS Index
The diffusion tensor imaging along perivascular spaces (DTI-ALPS) index is a non-invasive marker related to perivascular diffusion, but its reliance on fixed scanner-aligned axes makes it sensitive to head tilt and anatomical variability. We describe a refinement that computes directional diffusivities along subject-specific axes derived from tract ...

DTI-ALPS index as a predictor of glymphatic system dysfunction in cerebral infarction
To evaluate glymphatic system (GS) dysfunction in patients with cerebral infarction using diffusion tensor imaging - along the perivascular space (DTI-ALPS), and to investigate factors associated with glymphatic function impairment following stroke.A retrospective study was conducted on 82 patients diagnosed with cerebral infarction at Zhujiang ...
