Mutation carriers without ataxia differed from controls by significantly more upper motor signs (SCA1 P=0.0003, SCA3 P=0.003) and by the presence of sensor impairment and diplopia in SCA3 (P=0.0448, and 0.0445 respectively). Functional scales, fatigue and depression scores, swallowing difficulties, and cognitive impairment were worse in mutation carriers with ataxia than those without ataxia. Ataxic SCA3 subjects showed extrapyramidal signs, urinary dysfunction and lower motor neuron signs significantly more often than mutation carriers without ataxia.Discussion: READISCA showed the feasibility of harmonized data acquisition in a multi-national network. NfL alterations, early sensory ataxia and corticospinal signs were quantifiable between preataxic participants and controls. Patients with ataxia differed in many parameters from controls and mutation carriers without ataxia, with a graded increase of abnormal measures from control to preataxic to ataxic cohorts. %U //www.ez-admanager.com/content/neurology/early/2023/02/16/WNL.0000000000207088.full.pdf
