Statistical parametric maps of significant fractional anisotropy change in the Tourette syndrome cohort superimposed for presentation purposes at P < 0.001, uncorrected on T1-weighted image. Right panel: regression coefficients (betas) extracted from the voxel of maximum intensity over Tourette syndrome (TS) sub-groups depending on the presence (+) or absence (−) of co-morbidity OCD/ADHD. (A) Fractional anisotropy decreases in patients with Tourette syndrome compared with controls. (B) Fractional anisotropy reductions in patients with Tourette syndrome with symptom severity increase [motor tic sub-score, premonitory urge for tics score (PUTS)]. [x, y, z] coordinates refer to the Montreal Neurological Institute standardized space. Colour scales on the right indicate t-values.
