Glymphatic dysfunction in classical trigeminal neuralgia: DTI-ALPS index stratification from healthy controls to post-MVD

The Journal of Headache and Pain
The diffusion tensor imaging analysis along the perivascular space (DTI-ALPS) index is a non-invasive marker of glymphatic function. Its relevance in classical trigeminal neuralgia (CTN), postoperative glymphatic changes after microvascular decompression (MVD), and associations with clinical and structural measures remain unclear.

Impaired Glymphatic Function in Diffuse Axonal Injury: Evaluation Using the Diffusion Tensor Imaging Analysis Along the Perivascular Space (DTI-ALPS) Method

PURPOSE: Glymphatic system impairment has been suggested in previous animal and human studies regarding traumatic brain injury (TBI). Diffuse axonal injury (DAI) is an important pathological feature of TBI and is frequently diagnosed in patients with ...

Perivascular spaces, diffusion MRI markers and cognitive decline in cerebral small vessel disease

Cerebral Circulation - Cognition and Behavior
Background: MRI markers, including visible perivascular spaces (PVS), diffusion tensor image analysis along the perivascular space (DTI-ALPS) index, and peak width of skeletonized mean diffusivity (PSMD) may capture the earliest pathogenesis of cerebral ...

Reassessment of the DTI-ALPS index in focal epilepsy

European Radiology Experimental
Objective Recent evidence highlights the limited specificity of diffusion tensor imaging (DTI) along perivascular spaces (ALPS) as a noninvasive glymphatic biomarker because microstructural tract degeneration and crossing-fiber geometry confound it.

DTI-ALPS REFLECTS WHITE MATTER DIFFUSION ANISOTROPY AND MICROSTRUCTURAL HETEROGENEITY RATHER THAN GLYMPHATIC FLOW: INSIGHTS FROM MULTI-MODAL MRI

The glymphatic system plays a critical role in the clearance of metabolic waste and pathological proteins such as amyloid-β and tau from the brain, and its dysfunction has been increasingly implicated in the pathogenesis of neurodegenerative diseases ...
