ATXN3 and cerebellar ataxia: Again, PHQ-9 scores were lower than those from a European (mean ± SD, 6.9 ± 6.2, difference p < 0.001) and American SCA3 cohort (mean ± SD, 7.3 ± 5.8, difference p < 0.001) with mixed ataxia severities but higher than in preclinical SCA3 mutation carriers (median 2.0, IQR 0.0–3.0) [3, 5, 7].
