Motor and nonmotor symptoms were evaluated using the Scale for the Assessment and Rating of Ataxia (SARA) and an extensive neuropsychological battery.

Furthermore, P300 latency had the highest AUC in the discrimination of SCA1 in ROC analysis. The expansion of trinucleotide repeats correlated with P300 latency (r=\u22120.607, p=0.048), whereas both P300 and N100 amplitudes correlated with the severity of motor symptoms (r=\u22120.692, p=0.003; r=\u22120.621; p=0.010).
