Graph analysis revealed regional intra-cerebellar FC changes in FRDA, marked by reduced functional centrality in cerebellar regions of the vermis and responsible for executive functions. These changes correlated with cognitive alterations, highlighting the role of the cerebellar cortex in the cognitive impairment observed in FRDA. In conclusion, our observations confirm that the cerebellum is involved in the pathophysiology of FRDA not only from a structural, but also from a functional standpoint, and suggests that integrating information from different parcellations could provide complementary knowledge and help us in decoding the exact relationship between FC alterations and cognitive changes in FRDA.
