Multiple sclerosis: environmental risk factors

Abstract

Multiple sclerosis is a disease of unknown etiology characterized by inflammory demyelination of the brain and spinal cord. Epidemiological investigations play important role in study of multiple sclerosis. Geographical distribution of the disease has been described in terms of prevalence and incidence. The possible role of environmental factors as a cause of multiple sclerosis had been hypothesized with observation of unequal geographic distribution of the disease. More interesting, in terms of their biological significance, are attempts to identify associations between multiple sclerosis and situations or events wich could cause blood-brain barrier damages, such as trauma or toxic exposures.
