MD: mean diffusivity; FA: fractional anisotropy; NAA: N-acetylaspartate; Cho: choline; Cr: creatine; W1: the first week; W4: the fourth week; W12: the twelfth week.

Asymmetry indices: thalamic ipsilateral/contralateral MRI Parameter value in patients and right/left MRI Parameter value in controls.

^aP< 0.05, Tukey test, compared to W1; ^bP< 0.05, Tukey test, compared to W4; ^cP< 0.05, Student's t test, compared to the control group.
