Results of the region-of-interest (ROI)-based analyses of five patients and five age- and gender-matched controls.

FA values are given as mean ± SD. Significance level was determined by Student's t-test. Left- and right-hemispheric ROIs are arithmetically averaged for each localisation (except from corpus callosum where only one ROI was selected) since there were no asymmetric findings in all of them. MNI, Montreal Neurological Institute; FA, fractional anisotropy.
