Muscular dystrophy

Also called Duchenne muscular dystrophy, Becker muscular dystrophy, or Myotonic dystrophy

Muscular dystrophy is a group of inherited conditions that cause the muscles to gradually weaken, leading to an increasing level of disability. There are many types. Duchenne muscular dystrophy, one of the most common and severe, usually affects boys and starts in early childhood. Other types can start in adulthood and progress slowly.

What it is

Some types can also affect the heart and the muscles used for breathing.

There is no cure, but physiotherapy, steroids, newer targeted medicines for some types, and heart and breathing care can help.

Common signs

  • Muscle weakness that gets worse over time
  • Difficulty walking, running or climbing stairs
  • Frequent falls
  • Difficulty getting up from the floor
  • Muscle stiffness

How it is usually diagnosed

  • Blood test for creatine kinase
  • Genetic testing
  • Muscle biopsy, sometimes
  • Heart and breathing tests

Records worth keeping

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

  • Genetic test results
  • Heart and breathing test results over time
  • Neuromuscular clinic letters
  • Physiotherapy plans

Questions to ask your doctor

  • Which type of muscular dystrophy is it?
  • How will the heart and breathing be monitored?
  • Are there treatments or trials for this type?

When to get help right away

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

  • Breathing difficulty, a chest infection with breathlessness, or chest pain: call 112
