NC, normal controls; a-MCI, amnestic mild cognitive impairment; CSVD-MCI, mild cognitive impairment resulting from cerebral small vessel disease; ATR, anterior thalamic radiation; CST, corticospinal tract; CgC, cingulum (cingulate gyrus); CgH, cingulum (hippocampus); Fma, forceps major; Fmi, forceps minor; IFO, inferior fronto-occipital fasciculus; ILF, inferior longitudinal fasciculus; SLF, superior longitudinal fasciculus; UF, uncinate fasciculus; tSLF, superior longitudinal fasciculus-temporal part; L, left; R, right; FA, fractional anisotropy. FA values are mean ± SD.

Post-hoc paired comparisons showed significant group differences: ^aP < 0.05 between NC and a-MCI; ^bP < 0.05 between NC and CSVD-MCI; ^cP < 0.05 between a-MCI and CSVD-MCI.
