We used optimized voxel-based morphometry to study similarities and differences of regional gray matter volume development in relapsing remitting and secondary progressive MS. Although regional gray matter volume measures reveal areas of significant gray matter volume loss in RRMS, the results from this study suggest, that there is no marked acceleration in the progressive phase of the disease. This implies that the more pronounced impact of gray matter pathology in the secondary progressive phase is a result of longer linear accrual of such damage, rather than a phase-specific acceleration.
