is a condition where the myelin sheaths coating neurons within the nervous system are systematically removed leading to neurons enflaming and giving rise to multifocal scarring of remaining protective sheaths. Initial symptom of MS include: visual disturbance, such as blurred or double vision, red- green colour distortion, or blindness in one eye. Later symptoms include fatigue, weakness in the hands and feet, numbness, stiffness or muscular spasms, muscle and back pain, difficulties with coordination and balance, loss of bladder or bowel control, and depression.
