Correlation of grey matter atrophy to motor and cognitive function in SPG11. A Motor function (as measured by the SPRS score) correlates to basal ganglia and mesencephalic atrophy. B Verbal fluency (as measured by the verbal fluency semantic score) correlates to fronto-parietal cortical atrophy. r Spearman’s rho correlation coefficient, SPRS spastic paraplegia rating scale, GM grey matter
