Diagnosis of Multiple Sclerosis (MS)
- MRI scan—This test uses magnetic and radio waves to check for damage to the myelin sheath of the nerves in the brain and spinal cord. A contrast substance may be used to help doctors identify damaged areas. MRI may also be used to track changes in the disease.
- Evoked responses—This test records the speed of the electrical responses in sensory, visual, or auditory nerves after a repeated sensory stimulus. This test can help identify abnormal areas affected by MS. Visual evoked potential tests are most often used in evaluating MS.
- Lumbar puncture—In this procedure, a small amount of fluid from around the spinal cord is removed and checked for white blood cells, antibodies, and proteins. Doctors look for abnormal changes associated with MS.
