Alzheimer’s disease(AD)is associated with the impairment of white matter(WM)*** current study aimed to verify the utility of WM as the neuroimaging marker of AD with multisite diffusion tensor imaging datasets[321 patients with AD,265 patients with mild cognitive impairment(MCI),279 normal controls(NC)],a unified pipeline,and independent site *** fiber quantification was used to extract diffusion profiles along ***-effects meta-analyses showed a reproducible degeneration pattern in which fractional anisotropy significantly decreased in the AD and MCI groups compared with *** learning models using tract-based features showed good generalizability among independent site *** diffusion metrics of the altered regions and the AD probability predicted by the models were highly correlated with cognitive ability in the AD and MCI *** highlighted the reproducibility and generalizability of the degeneration pattern of WM tracts in AD.
