Multiple Sclerosis

Daniel M. Harrison, MD

Multiple sclerosis (MS) is an autoimmune condition that results in inflammatory damage to the central nervous system (CNS). The pathologic hallmarks of MS are diffuse and focal areas of inflammation, demyelination, gliosis, and neuronal injury in the optic nerves, brain, and spinal cord. In addition to affecting white matter tracts, MS results in injury to the cortical and deep gray matter. The neurologic symptoms and disability that patients with MS experience are a direct consequence of these pathologic processes, resulting in acute and chronic disruption of white matter tracts and gray matter structures.
