However, the association of WMH, Aβ plaques, and tau tangles in AD remains elusive. Using two large datasets, this study comprehensively examined the relationship between regional WMH and longitudinal tau accumulation in AD.  \nMethod: A total of 951 participants from theADNI andA4 cohorts with Aβ-PET, fluidattenuated inversion recovery images (FLAIR), and tau-PET data were included, with Resting-state functional MRI (RS-fMRI) available for a subset of participants. FLAIR images were segmented using a U-Net deep learning model to obtain regional WMH volumes. Tau propagation along connectivity patterns was assessed using connectivityassociated tau spread metrics derived for the whole cortex and specific cortical regions (βGlobal , βFrontal , βParietal , βTemporal , and βOccipital ). We examined the associations between regional WMH, tau accumulation, and connectivity-associated tau spread. Additionally, two cortical tau subtypes were identified: “Occipital > Parietal” and“Parietal > Occipital”, characterized by higher or lower occipital tau relative to parietal tau, and the impact of regional WMH on tau accumulation was assessed within these subtypes.  \nResult: Aβ+ individuals showed higher baseline levels and faster increases in total WMH compared to Aβ - individuals, but no differences were observed between T+ and T-individuals. Among Aβ+ individuals, temporal meta-ROI tau was not associated with faster WMH increases. However, greater total WMH was linked to accelerated temporal meta-ROI tau accumulation (Figure 1), although this relationship did not persist after controlling for Aβ. Greater occipital WMH was associated with faster tau  \nThis is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.  \n© 2025 The Alzheimer’s Association.
