Abstract Late-onset Tay-Sachs (LOTS) disease and late-onset Sandhoff (LOSD) have long been considered indistinguishable due to similar clinical presentations shared biochemical deficits. However, recent magnetic resonance imaging (MRI) studies shown distinct cerebellar atrophy associated with LOTS. In this study, we furthered investigation determine if the is globally uniform or preferentially targets certain regions. We utilized DeepCERES , a deep learning specific segmentation cortical thickness pipeline analyze differences between LOTS (n=20), LOSD (n=5), neurotypical controls (n=1038). had smaller volumes of whole cerebellum as well lobules IV, V, VI, VIIB, VIIIA, VIIIB, IX, both Crus I II compared controls. patients also Cerebellar functional lesion localization implicated V VI in speech articulation execution while I, VIIA, among others, variety behaviors neuropsychiatric symptoms. Our observations provide possible anatomical substrate higher prevalence dysarthria psychosis our but not patients. Future are needed for direct comparisons considering phenotypic aspects such age symptom onset, presence severity ataxia, full characterization profiles, molecular pathology fully understand dichotomy observed these two diseases.
