Multiple sclerosis (MS) is a chronic and disabling disease that attacks the
central nervous system (CNS). The symptoms, progression, and severity of the
disease are unpredictable and vary from one person to another. Major symptoms
include fatigue, sensory-motor (e.g., visual disturbance, spasticity,
locomotion), cognitive (e.g., decreased information processing speed, impaired
memory), and psychiatric problems (e.g., depression). Although the etiology is
unknown, MS is thought to be an autoimmune disease triggered by a viral or other
infectious agent in genetically susceptible individuals. The CNS target of the
disease is myelin, although it is now known that other aspects of the CNS such as
axonal and gray matter regions are also involved.
