Correlation of FA with tic severity. There was a negative correlation (red) between tic severity (according to YGTSS) and the FA in prefrontal areas, the cingulate gyrus, and the right thalamus. Tic severity correlated positively with FA (blue) in the body of the CC, the left thalamus, and the right superior temporal gyrus (p < 0.001, uncorrected).
