In 30 mTBI patients, vestibular disturbances correlated with (a) decreased FA in cerebellar regions and (b) increased mean diffusivity in vermian lobules of the spinocerebellum, while convergence insufficiency in 25 mTBI patients correlated with (c) increased FA in the right anterior thalamic and right geniculate nucleus optic radiations. Images were derived from tract-based spatial statistics (TBSS) results and rendered on T1-weighted images from the Montreal Neurologic Institute in coronal (a), sagittal (b), and axial (c) projections. Significant voxels (P < .05, corrected for multiple comparisons) were thickened by using TBSS fill function into local tracts (red) and overlaid on WM skeleton (blue). (Reprinted from reference 61.)
