Multiple Sclerosis

Multiple sclerosis (MS) is a demyelinating disease in which the myelin in the brain and spinal cord is damaged. This damage disrupts the ability of parts of the nervous system to communicate, resulting in a range of signs and symptoms, including double vision, blindness in one eye, muscle weakness, trouble with sensation, or trouble with coordination.
MS takes several forms, with new symptoms either occurring in isolated attacks (relapsing forms) or building up over time (progressive forms). Between attacks, symptoms may disappear completely; however, permanent neurological problems often remain, especially as the disease advances.
