What is the outcome of Duchenne muscular dystrophy?
Without dystrophin, muscle cells become damaged and weaken. Over time, children with Duchenne will develop problems walking and breathing, and eventually the muscles that help them breathe and the heart will stop working. Duchenne is an irreversible, progressive disease. There is currently no cure for Duchenne.
What is the mechanism of Duchenne muscular dystrophy?
The disease is caused by mutations in DMD (encoding dystrophin) that abolish the production of dystrophin in muscle. Muscles without dystrophin are more sensitive to damage, resulting in progressive loss of muscle tissue and function, in addition to cardiomyopathy.
What is the solution to muscular dystrophy?
Muscular dystrophy (MD) is a group of over 30 genetic diseases causing progressive weakness and loss of muscle mass. Although there is no cure, medication and physical therapy can reduce symptoms and slow the condition’s progression.
What are the specific symptoms of Duchenne muscular dystrophy?
Duchenne type muscular dystrophy
- Frequent falls.
- Difficulty rising from a lying or sitting position.
- Trouble running and jumping.
- Waddling gait.
- Walking on the toes.
- Large calf muscles.
- Muscle pain and stiffness.
- Learning disabilities.
Can DMD be cured?
There is no known cure for Duchenne muscular dystrophy. Treatment aims to control symptoms to improve quality of life. Steroid drugs can slow the loss of muscle strength.
How long do people with muscular dystrophy live?
Until recently, children with Duchenne muscular dystrophy (DMD) did not often live beyond their teens. However, improvements in cardiac and respiratory care mean that life expectancy is increasing, with many DMD patients reaching their 30s, and some living into their 40s and 50s.
Can a man with muscular dystrophy have a baby?
Carriers may not have any disease symptoms but can have a child with the mutation or the disease. DMD carriers are at risk for cardiomyopathy. Although DMD often runs in a family, it is possible for a family with no history of DMD to suddenly have a son with the disease.
Is muscular dystrophy inherited from the mother or father?
In most cases, muscular dystrophy (MD) runs in families. It usually develops after inheriting a faulty gene from one or both parents. MD is caused by mutations (alterations) in the genes responsible for healthy muscle structure and function.
Is Muscular Dystrophy painful?
MMD patients may experience painful muscle cramping because of myotonia, which is delayed relaxation or sustained contraction of the muscle fibers.
At what age is DMD diagnosed?
Duchenne muscular dystrophy (DMD) is a rare muscle disorder but it is one of the most frequent genetic conditions affecting approximately 1 in 3,500 male births worldwide. It is usually recognized between three and six years of age.
