Multiple Sclerosis Overview
Multiple sclerosis (MS) can be thought of as an immune-mediated inflammatory process involving different areas of the central nervous system (CNS) at various points in time. As the name suggests, multiple sclerosis affects many areas of the CNS.
Multiple Sclerosis Causes
The central nervous system is made up of the brain and spinal cord. They process information from our environment and control voluntary muscle movements to allow the body to do certain things.
This neural system works efficiently, unless there is a disease process affecting the pathways in the spinal cord and brain. Multiple sclerosis is one of the diseases that can affect these pathways.
Multiple sclerosis results in destruction of the myelin surrounding the nerves of the CNS. The destruction is caused by the body's immune system attacking the myelin sheath. The reason that the body's immune system attacks the myelin sheath is not understood fully, but it is believed to be related to a combination of a genetic predisposition and acquired or environmental influences.
