White matter (WM) is composed of various functional nerve fibers and plays an indispensable role in the central nervous system. However, the WM signal changes and their correlation with major depression disorder (MDD) in adolescents are still unclear.
An increasing number of studies have confirmed the functional organization of WM by the resting state functional magnetic imaging (rs-fMRI), indicating its feasibility of studying WM function in adolescents with MDD.
The purpose of this study is to explore the functional changes in the WM of adolescents with MDD.
We collected rs-fMRI data and clinical scale information from the adolescent group with MDD and the healthy control group, and analyzed the correlation between WM function signals and clinical scales in the two groups.
We found significant changes in the functional signals of WM in adolescents with MDD, using the fractional amplitude of low frequency fluctuations, regional homogeneity, and independent component analysis. There are two brain regions, the left posterior limb of the inner capsule and the right posterior corona radiata, which are negatively correlated with the mini international neuropsychiatric interview suicide scales.
The discovery of changes in WM functional signals in adolescents with MDD is of great significance for understanding the neuropathogenesis of depression.
Our research findings may serve as biomarkers for predicting the risk of MDD and suicide in adolescents.
