Multiple sclerosis (MS) is a disease of the nervous system that affects the brain and spinal cord. It damages the myelin sheath, the material that surrounds and protects nerve cells. The injury slows down or blocks messages between the brain and the body, leading to the symptoms of MS.

They may include: 

  • Vision impairment 
  • Muscle weakness 
  • Problems with coordination and balance 
  • Sensations such as numbness, itching, or punctures 
  • Problems with thinking and memory. No one knows the cause of MS. It can be an autoimmune disease, which occurs when the body attacks itself. Multiple sclerosis affects women more than men. It usually starts in the 20's and 40's. Generally, the disease is mild, but some people lose the ability to write, talk, or walk. There is no cure for MS, but medications can slow the process and help control symptoms. Physical therapy and occupational therapy can also help.
