Mean GAA expansions were longGAA=1001±291 and shortGAA=843±212. Transversal group analyses showed extensive microstructural damage including superior cerebellar peduncles, corpus callosum(CC) and pyramidal tracts. Longitudinal TBSS revealed progressive microstructural abnormalities at the corpus callosum, pyramidal tracts and superior cerebellar peduncle after one year of follow-up. FA at pyramidal tracts correlated with FARS score and disease duration. We also found that FA at the posterior part of CC correlated with FARS score and disease duration. CONCLUSIONS:Patients with FDRA present widespread WM damage and have progressive microstructural abnormalities, which are detectable in a short-term of follow-up.
