- Damage to the myelin sheath, a protective fatty substance that surrounds nerve cells within the brain and spinal cord

- An MRI machine uses a magnetic field and radio waves to create detailed images of the brain.

- A protective fatty substance that surrounds nerve cells within the brain and spinal cord.
- A diagnostic sign indicating abnormal levels of certain antibodies(proteins called immunoglobulins) in the cerebrospinal fluid; seen in approximately 90% of people with multiple sclerosis. The presence of these bands suggests inflammation in the central nervous system.
- Inflammation or demyelination of the optic (visual) nerve that causes temporary or permanent impairment of vision and, occasionally, pain.
- A neurologic disorder caused by inflammation (swelling) across both sides of one level or segment of the spinal cord. Inflammation can damage or destroy myelin, the fatty protective substance that covers nerve cell fibers. This damage causes scars that interrupt the communication between the nerves in the spinal cord and the rest of the body. Most people affected by transverse myelitis will have only one attack; a small percentage may have more than one attack.
