Duchenne Muscular Dystrophy
Treatments
Steroids are used to slow the loss of muscle strength.
Activity is recommended, because bed rest would make the muscles weaker. Physical therapy is used to strengthen the muscles.
Speech therapy is also frequently used.
Etiology
X-chromosome based.
Females can carry the disease, but not be affected.
Males are only affected and usually die early.
Pathology
DMD creates a defective X-chromosome that stops the production of dystrophin.
It does not affect the females because they use the X-chromosome that is not defective.
There is a 50% chance of using an egg with a defective X-chromosome.
