Neuroimaging Biomarkers for Friedreich Ataxia: A Cross-Sectional Analysis of the TRACK-FA Study Objective Our study aims to quantify differences in the brain and spinal cord between individuals with Friedreich's ataxia and healthy controls. This includes stratification by age and disease stage, and for the first time, the inclusion of young children.
