Pathology of Multiple Sclerosis

MS is heterogeneous with respect to clinical, genetic, radiographic, and pathologic features; surrogate MRI, clinical, genetic, serologic, and/or CSF markers for each of the four immunopatterns need to be developed in order to recognize them in the general nonbiopsied MS population. Inflammatory cortical demyelination is an important early event in the pathogenesis of MS and may be driven by meningeal inflammation. These observations stress the importance of developing imaging techniques able to capture early inflammatory cortical demyelination in order to better understand the disease pathogenesis and to determine the impact of potential disease-modifying therapies on the cortex.
