Transdiagnostic Reductions in Glymphatic-Related Perivascular Diffusion Across Psychiatric Disorders: A Systematic Review and Meta-analysis.
BACKGROUND The glymphatic system, a perivascular pathway supporting cerebrospinal and interstitial fluid exchange and clearance, has been implicated in neurodegenerative and psychiatric disorders. Diffusion tensor imaging along the perivascular space (DTI-ALPS) provides a non-invasive proxy for glymphatic-related proce...
