Infographic: Multiple Sclerosis

Multiple Sclerosis

A stripped wire.

In Multiple Sclerosis, the immune system attacks the protective sheath (myelin) around nerves in the brain, eye and spinal cord.

As with damaged electrical wires, signals sent along damaged nerves between brain and body can be slowed or blocked.

MS symptoms include:

  • Dizziness
  • Loss of vision
  • Double vision
  • Unsteady gait
  • Weakness
  • Tremors
  • Bladder problems
  • Numbness

At least 2.3 million people worldwide have MS – more than the population of Orlando.

The average person in the U.S. has about a 1 in 750 (0.13%) chance of developing MS.

The course of MS.

Most people with MS have a relapsing-remitting course, which often develops into secondary-progressive. Others never experience periods of relapse; this is called primary-progressive.


Periods of new symptoms, followed by periods of remission—the most common course.

Secondary Progressive

Periods of new symptoms, followed by steady progression of symptoms.

Increasing Disability over Time

Primary Progressive

Gradual onset and steady progression without remission.

New treatments and research offer a bright future.

Treating attacks:

Steroids or plasma exchange are used to treat new symptoms. Most patients improve.

Preventing attacks:

14 injectable, oral and infusion therapies are approved to prevent new symptoms and disability.

Managing symptoms:

Patients with MS require an integrated team, tailored to their needs to manage symptoms like: weakness, walking problems, muscle stiffness, bladder problems.
