Find out what to look for

The immune system behaves abnormally in MS. Instead of fighting infections, some B cells and T cells are misdirected to attack myelin (the fatty sheath that protects nerves and helps maintain the signals carried by the nerves).

The exact cause is unknown, but it's believed that factors such as genetics, viral infection, and even diet could play a role.

Everyone with MS has a unique experience, so the symptoms you experience may be different from others. While some people have trouble with walking and balance, others may experience numbness and vision changes. Some common symptoms include:

Physical symptoms

  • balance problems
  • bladder dysfunction
  • bowel problems
  • mobility and walking issues
  • sexual dysfunction
  • spasticity (stiffness)
  • speech difficulties
  • swallowing disorders

  • numbness
  • pain
