The most common form of muscular dystrophy is Duchenne muscular dystrophy.
Duchenne muscular dystrophy is the most common form of muscular dystrophy. Girls are carriers and somewhat affected, but DMD is much more common in boys.
Some boys don’t have a family history of the disease because the gene mutation may happen due to a spontaneous mutation. But these cases are also rare.
Signs in early childhood may include:
- Frequent falls
- Difficult getting up from a sitting position
- Waddling gait
- Trouble running and jumping
- Walking on the toes
- Large calf muscles
- Muscle pain and stiffness
- Learning disabilities
Another form of muscular dystrophy is called Becker muscular dystrophy. The signs and symptoms are like those of Duchenne muscular dystrophy, but they are milder and progress slower. Symptoms do not start until your child is in their teens and the disease may not hit until the mid-20s.
Other types of muscular dystrophy include myotonic or Steinert’s disease, facioscapulohumeral (where muscle weakness begins in the face and shoulders), congenital and limb-girdle, which begins to change the hips and shoulder muscles.
