Structural T1\u2010weighted MRI scans were processed using FreeSurfer and the Spatially Unbiased Infratentorial toolbox (SUIT) for cerebellar lobule segmentation. Multivariate linear regression and mediation analyses were conducted to examine associations among cerebellar lobular volumes, cognitive domains, and New Freezing of Gait Questionnaire (N\u2010FOGQ) scores.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Patients with MSA\u2010FOG exhibited deficits in executive function, visuospatial ability, attention, working memory, language, and delayed recall, alongside significant atrophy in global cerebellar gray matter and lobules I\u2013X.
