The study aims to determine the relationship between choroid plexus microstructural changes and cognitive performance in cerebral small vessel disease.
Used diffusion imaging to assess choroid plexus microstructure in 139 CSVD patients and 52 healthy controls.
Evaluated perivascular clearance measures using DTI-ALPS index, FW-BG, and PVSVF-BG.
Applied random-forest modeling to identify predictors of CSVD severity.
Conducted mediation analysis to examine the effects of fluid transport on cognitive performance.
CSVD patients displayed significant microstructural abnormalities in the choroid plexus compared to controls.
Imaging markers of perivascular clearance significantly mediated the relationship between CP changes and brain injury.
PVSVF-BG was identified as a key metric linking CP volume and cognitive performance.
