  • MD, RD, AD are ×10−3 mm2/s. The boldened p-values indicate statistically significant group differences.

  • AD, axial diffusivity; Cho, choline; Cr, creatine; FA, fractional anisotropy; MD, mean diffusivity; PMC, primary motor cortex; RD, radial diffusivity; tNAA, total NAA moieties; WM, white matter.
