Transcript of Muscular Dystrophy
Muscular Dystrophy occurs in about 3 - 6 out of every 100,000 births. The disease is found mostly in boys affecting 1 out of every 3,500 boys.
How does this relate to homeostasis?
One way is abnormal calcium:
This large abnormal amount of calcium creates a homeostatic imbalance and damages the contractile fibers which then breakdown the surrounding connective tissue. This reduces the regenerative capacity of the muscle and the damaged cells
undergo apoptosis, (programmed cell death), resulting in decreasing muscle mass.
What causes it?
The disorder is passed down through families (inherited). Having a family history of the condition raises your risk.
Is there any treatments?
There is no known cure for Muscular Dystrophy. The goal of treatment is to control symptoms to maximize the person's quality of life. Some doctors prescribe steroids to help keep a patient walking for as long as possible.Activity is encouraged. Inactivity (such as bed rest) can make the muscle disease worse. Physical therapy may be helpful to maintain muscle strength. Orthopedic appliances such as braces and wheelchairs may improve movement and self-care.
