PwMS without tremor served as matched controls.

The tremor group (n\u2009=\u200936) exhibited significant changes in several pathways, notably in the right inferior longitudinal fasciculus (Cohen's d\u2009=\u20091.53, q\u2009&lt;\u20090.001) and left corticospinal tract ( d\u2009=\u20091.32, q\u2009&lt;\u20090.001), compared to controls (n\u2009=\u200936). Furthermore, specific tracts showed a significant correlation with tremor severity, notably in the left medial lemniscus (Spearman's coefficient [ r<jats:sub>s<\/jats:sub>p]\u2009=\u2009\u22120.56, p\u2009&lt;\u20090.001), and forceps minor of corpus callosum ( r<jats:sub>s<\/jats:sub>p\u2009=\u2009-0.45, p\u2009&lt;\u20090.01). <\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p> MS-related tremor is associated with widespread diffusivity changes in WM pathways and its severity correlates with
