Diffusion tensor imaging of white matter degeneration in Alzheimer's disease and mild cognitive impairment
Alzheimer’s disease (AD) has traditionally been regarded as a disease of the gray matter (GM).
However, the advent of diffusion tensor imaging (DTI) has contributed to new knowledge …

Individual variations in 'brain age'relate to early-life factors more than to longitudinal brain change
Brain age is a widely used index for quantifying individuals’ brain health as deviation from a
normative brain aging trajectory. Higher-than-expected brain age is thought partially to …

Relationship between structural and functional connectivity change across the adult lifespan: a longitudinal investigation
Extensive efforts are devoted to understand the functional (FC) and structural connections (SC)
