BAEPs and p-VEPs are highly prevalent and closely associated with clinical severity in chronic FRDA, outperforming tested serum biomarkers.
Evoked potentials provide accessible, non-invasive, quantitative candidate biomarkers for severity assessment and longitudinal monitoring in FRDA, supporting their use in clinical practice and trial design when fluid markers are inconclusive.
