This ongoing study is the first report of a long-term (10 years) follow-up on brain atrophy in MS. Brain volume loss is, on average, -5% in MS patients and -3% in normal controls. It seems to be a global process, involving all tissue compartments. Brain atrophy rate, both global and in the grey matter, was associated to clinical worsening, particularly in subject with higher frequency of clinical relapses and progressing disability. This suggests that long-term global and grey matter brain atrophy change may provide a valuable outcome of longstanding disability and progression in patients with MS
