What is muscular dystrophy?

Muscular dystrophy is a general name for a group of rare diseases that cause muscle weakness. It is caused by mutations in certain genes. There are more than 30 different types of muscular dystrophy and each affects certain muscles and varies in severity. Some types of muscular dystrophy affect children while others don’t appear until adulthood.

The most common type, called Duchenne muscular dystrophy, usually begins between ages 2 to 5 and symptoms progress quickly. About 50 percent of all people with muscular dystrophy have this type. Duchenne muscular dystrophy most often affects boys, though girls can inherit the gene and pass it to their children.

Some other types of muscular dystrophy that can affect children include:

  • Becker: This type is related to Duchenne muscular dystrophy, but is less severe.
  • Emery-Dreifuss: Most common in boys, this type of muscular dystrophy causes weakness and progressive wasting of the lower leg and upper arm muscles.
  • Facioscapulohumeral: This type affects muscles in the face, upper arms and shoulders.
  • Limb-girdle: This is a group of more than 20 inherited conditions that cause progressive muscle loss and weakness.
  • Myotonic dystrophy: This is the most common muscular dystrophy in adults, but symptoms can sometimes begin in infancy or childhood.
  • Distal: Also called distal myopathy, is a less severe form of muscular dystrophy that usually progresses slowly.

All types of muscular dystrophy get worse over time, and can eventually cause the inability to walk. Some types of muscular dystrophy can also cause problems with breathing.

There is no cure for muscular dystrophy, but treatments can prevent complications and help with symptoms.

How we care for muscular dystrophy

At the Boston Children’s Hospital Neuromuscular Center, our team of specialists from neurology, orthopedic surgery, physical therapy and genetics are experienced in caring for children with muscular dystrophy. We are one of a few sites in the United States funded by the National Institutes of Health (NIH) and various sponsors to conduct clinical studies on muscular dystrophy.

Boston Children’s is so much more than a hospital—it’s a community of researchers, clinicians, administrators, support staff, innovators, teachers, patients and families, all working together to make the impossible possible. ”
