Clinically Isolated Syndrome Suggestive of Multiple Sclerosis: Dynamic Patterns of Gray and White Matter Changes—A 2-year MR Imaging Study

Abstract

After an acute inflammatory event, dynamic modifications of regional GM and WM damage occur in patients with CIS, with a progressive evolution of WM damage from disease onset and a transient, early increase in GM volume, followed by GM atrophy. Neurodegenerative processes start early in patients with multiple sclerosis.
