Longitudinal diffusion imaging across the <i>C9orf72</i> clinical spectrum

Abstract

Discrepancies between DTI findings and clinical measures of disease severity in ALS may partly be accounted for by cognitive-behavioural deficits affecting extramotor white matter tracts. Both ALSFRS-R and King's stage correlated with corticospinal DTI measures. Group-level DTI changes could be detected over 6 months.
