Discovery of the day
This study demonstrates that MRI-visible enlarged perivascular spaces (PVS) in the basal ganglia are linked to faster white matter hyperintensity progression and amyloid accumulation. Researchers analyzed 2,229 participants and found that basal ganglia PVS burden predicted worsening white matter disease and amyloid deposition, particularly in amyloid-negative individuals. For your focus on multimodal biomarkers of Alzheimer’s disease, this finding positions PVS as an imaging-based marker of small vessel dysfunction that could complement blood-based proteomic and clinical data to improve early disease staging and risk stratification.
