Multiple sclerosis

Also called MS or Relapsing remitting MS

Multiple sclerosis (MS) is a condition that can affect the brain and spinal cord, causing a wide range of symptoms, including problems with vision, arm or leg movement, sensation and balance. It is a lifelong condition, usually diagnosed in people in their 20s to 40s, and is more common in women. Most people start with relapses and recovery (relapsing remitting MS).

What it is

There is no cure, but disease-modifying medicines can reduce relapses and slow progression.

Steroids can help with relapses, and physiotherapy and other support help with symptoms such as fatigue, spasms and bladder problems.

Common signs

  • Blurred vision or pain in one eye
  • Numbness or tingling
  • Fatigue
  • Problems with balance and walking
  • Muscle stiffness or spasms
  • Bladder problems

How it is usually diagnosed

  • Examination by a neurologist
  • MRI scans of the brain and spine
  • Lumbar puncture, sometimes
  • Evoked potential tests

Records worth keeping

Keeping these together makes each appointment easier, especially when you see a new doctor:

  • MRI reports over time
  • Neurology letters
  • Relapse dates and treatments
  • Disease-modifying medicine monitoring blood tests

Questions to ask your doctor

  • Which type of MS do I have?
  • Which disease-modifying treatment is right for me?
  • What should I do if I think I am having a relapse?

When to get help right away

Call 112 or go to the nearest emergency department if you have:

  • Sudden severe weakness, loss of vision, or difficulty breathing or swallowing: call 112
