Multiple Sclerosis Information
This common neurologic disorder, which probably has an autoimmune basis, has its greatest incidence in young adults. Epidemiologic studies indicate that multiple sclerosis is much more common in persons of western European lineage who live in temperate zones. No population with a high risk for multiple sclerosis exists between latitudes 40 °N and 40 °S. Genetic, dietary, and climatic factors cannot account for these differences. Nevertheless, a genetic susceptibility to the disease is likely, based on twin studies, familial cases, and an association with specific HLA antigens (HLA-DR2). Pathologically, focal-often perivenular-areas of demyelination with reactive gliosis are found scattered in the white matter of brain and spinal cord and in the optic nerves.
