Koscik, Aline Andres, Aline Andres, Jayne Bellando, Jayne Bellando, Charles M. Glasier, Charles M. Glasier, Adhitya Ram, Xiawei Ou, Xiawei Ou, Xiawei Ou, Xiawei Ou

“…Their children underwent a brain MRI examination at age 8 years with multi-shell diffusion imaging analyzed using diffusion tensor imaging (DTI), diffusional kurtosis imaging (DKI), and neurite orientation dispersion and density imaging (NODDI) models for a multi-aspect evaluation of microstructural development. Key diffusion metrics (FA: fractional anisotropy; MD: mean diffusivity; AD: axial diffusivity; RD: radial diffusivity; MK: mean kurtosis; AK: axial kurtosis; RK: radial kurtosis; NDI: neurite density index; ODI: orientation dispersion index; FWF: free water fraction) were extracted from the limbic system white matter structures including cingulum, fornix, and uncinate fasciculus, which are closely associated with emotional and motivational processes.ResultsHigher maternal depression symptom scores were associated with lower FA (R = –0.3126, p = 0.0305, in CGH.R; R = –0.3025, p = 0.0366, in FXC.R) and MK (R = –0.3284, p = 0.0227, in CGG.R) and higher MD (R = 0.2879, p = 0.0472, in CGH.R) and RD (R = 0.3451, p = 0.0163, in CGH.R; R = 0.3456, p = 0.0161, in FXC.R) in predominately right-hemisphere limbic tracts. …”
