title: MRI evaluation of grey matter atrophy and disease course in multiple sclerosis: an overview of current knowledge.
abstract: Multiple sclerosis (MS) is characterized by chronic inflammation of the central nervous system, and magnetic resonance imaging (MRI) is used as both a diagnostic tool and a parameter in the clinical evaluation. Multiple sclerosis was long regarded as a disease of the white matter (WM) in the brain, which can be visualized by the standard MRI used in daily practice. There is an increasing amount of evidence that grey matter (GM) pathology plays a role from the start of the MS disease and throughout the clinical course. Grey matter atrophy, both cortical and central, is present in the early course of MS and is also related above all to cognitive decline, but also to the development of physical disability as measured by EDSS. In this article, we give an overview of GM atrophy in MS evaluated by MRI and the relation to the clinical course in MS.
