We need to separate gray matter damage from white matter damage---
Dr. Dake is looking at gray matter atrophy in the patients he's treated so far and also in his new study...many progressive MS patients are showing gray matter atrophy. As we all know, it's not purely about white matter lesions, and gray matter seems to be a better biomarker of disease progression and disability. Jeff, who was diagnosed RRMS in 2007, did not have gray matter atrophy, but had 20 lesions. He still does not have gray matter atrophy, and his lesions are stable--some appear to have shrunk.
Here are several studies linking gray matter atrophy to disability:

http://www.ncbi.nlm.nih.gov/pubmed/18570297
Also remember, brain plasticity accounts for re-routing and return of function in stroke patients, and may account for pwMS who recover function and have cerebral lesions...but spinal damage is often permanent, due to the lower number of axons to recruit.
The premise behind intervention is to stop brain atrophy before the disease becomes progressive. We'll see how that goes...
