Results of voxel-based analyses showing A) cluster of reduced fractional anisotropy (FA) within the right cerebellum of cervical dystonia (CD) patients compared to healthy controls (HC), B) cluster of increased mean diffusivity (MD) within the left caudate nucleus in CD patients compared to HC, and C) clusters of decreased FA in the right cerebellum, left supramarginal gyrus, and right inferior frontal gyrus of CD patients compared to blepharospasm (BSP) patients. Voxel-based findings cluster thresholded for an overall p < 0.05, FWE corrected.
