All tracts were significantly associated with the modified global FA and one another, all P values < 0.001. The modified measure of global FA was used in these analyses and refers to the sum of all tracts excluding the tract examined. FA, fractional anisotropy; ATR, anterior thalamic radiation; CB, cingulum bundle; PHC, parahippocampal cingulum; CST, corticospinal tract; IFOF, inferior frontal occipital fasciculus; ILF, inferior longitudinal fasciculus; Fma, forceps major; Fmi, forceps minor; SLF, superior longitudinal fasciculus.
