abstract = {Alzheimer's disease (AD) and cerebral small vessel disease
(cSVD), the two most common causes of dementia, are
characterized by white matter (WM) alterations diverging
from the physiological changes occurring in healthy aging.
Diffusion tensor imaging (DTI) is a valuable tool to
quantify WM integrity non-invasively and identify the
determinants of such alterations. Here, we investigated main
effects and interactions of AD pathology, APOE-ε4, cSVD,
and cardiovascular risk on spatial patterns of WM
alterations in non-demented older adults.Within the
prospective European Prevention of Alzheimer's Dementia
study, we selected 606 participants (64.9 ± 7.2 years, 376
females) with baseline cerebrospinal fluid samples of
amyloid β1-42 and p-Tau181 and MRI scans, including DTI
scans. Longitudinal scans (mean follow-up time = 1.3 ± 0.5
years) were obtained in a subset (n = 223). WM integrity was
assessed by extracting fractional anisotropy and mean
diffusivity in relevant tracts. To identify the determinants
of WM disruption, we performed a multimodel inference to
identify the best linear mixed-effects model for each
tract.AD pathology, APOE-ε4, cSVD burden, and
cardiovascular risk were all associated with WM integrity
within several tracts. While limbic tracts were mainly
impacted by AD pathology and APOE-ε4, commissural,
associative, and projection tract integrity was more related
to cSVD burden and cardiovascular risk. AD pathology and
cSVD did not show any significant interaction effect.Our
results suggest that AD pathology and cSVD exert independent
and spatially different effects on WM microstructure,
supporting the role of DTI in disease monitoring and
suggesting independent targets for preventive medicine
approaches.},
