Sex differences in microstructural white matter alterations of mathematics anxiety based on diffusion MRI connectometry.

DMRI connectometry showed a significant association between AMAS score and increased microstructural connectivity in left arcuate fasciculus (AF), the body of corpus callosum (CC), right cingulum, and left inferior longitudinal fasciculus (ILF) in male participants with moderate effect size false discovery rate (FDR = 0.040). Furthermore, DMRI connectometry in females identified a positive correlation between AMAS score and microstructural connectivity in the genu of CC, right ILF, and bilateral fornices with small-to-moderate effect size (FDR = 0.012) and a negative correlation between AMAS score and microstructural connectivity in the bilateral cingulum with small-to-moderate effect size (FDR = 0.032) Conclusion: Our findings support that structures with functional relation to language processing areas (e.g., AF) or limbic system (cingulum, CC, fornix, and ILF) play a significant role in MA.
