Gray matter (GM) atrophy in multiple sclerosis represents neurodegeneration and appears to correlate with clinical measures. In this study, we implemented Tensor based morphometry (TBM) to assess regional gray matter atrophy in 250 MS subjects that were randomly chosen from a total of 1008 subjects who participated in a multi-center clinical trial. Significant atrophy was observed in various GM regions including major deep GM structures.
