Cover Story: This study investigates fractional anisotropy (FA) alterations within major white matter pathways across cognitive performance groups defined by the Montreal Cognitive Assessment. Interestingly, participants with moderate cognitive impairment demonstrated higher FA values in several association tracts compared to those with low performance. This paradoxical increase may reflect compensatory microstructural reorganization, selective axonal loss, or reactive gliosis, preceding overt degeneration. The findings highlight a nonlinear trajectory of white matter integrity in cognitive decline and underscore the potential of diffusion MRI as a sensitive biomarker of early neurodegenerative processes.
