Multiple Sclerosis Resources
Multiple sclerosis (MS) is an inflammatory disease which affects the ability of nerve cells in the brain and spinal cord to communicate with each other effectively. The name multiple sclerosis refers to scars (sclerae—better known as plaques or lesions) particularly in the white matter of the brain and spinal cord, which is mainly composed of myelin. Although much is known about the mechanisms involved in the disease process, the cause remains unknown. Theories include genetics or infections. Different environmental risk factors have also been found.
