Regression coefficients and significance for white matter alterations and cognitive performance. Verbal fluency scores were negatively correlated with AD values in the left ACR, ALIC and right SCR. Attention/working memory scores were positively correlated with AD values in the left ALIC and right SCR. Memory (learning and delayed recall) test scores were negatively correlated with MD values in the GCC, ACR (bilateral) and SCR (right). A positive correlation was observed between speed of information processing scores and MD values in the GCC, ACR (bilateral) and SCR (right), AD values in the GCC, ALIC (bilateral) and PTR (left). Fine motor scores were negatively correlated with MD values in the GCC, ACR (right) and SCR (right), AD values in the SCR (right)

Note: bar: P value; *: p < 0.1; **: p < 0.05; red circle: regression coefficients of MD; black square: regression coefficients of AD.

MD, mean diffusivity; AD, axial diffusivity; GCC, genu of corpus callosum; BCC, body of corpus callosum; SCC, splenium of corpus callosum; ACR, anterior corona radiata; SCR, superior corona radiata; ALIC, anterior limb of internal capsule; EC, external capsule; RIC, retrolenticular part of internal capsule; PCR, posterior corona radiata; PTR, posterior thalamic radiation; SS, sagittal stratum; SLF, superior longitudinal fasciculus. l, left; r, right; VF, Verbal Fluency; A/WM, Attention/ Working Memory; EF, Executive Functioning; M(LDR), memory (learning and delayed recall); SIP, Speed of Information Processing; FM, fine motor.
