MD is a hereditary condition marked by progressive weakening and wasting of the muscles
MD occurs mostly in males, 1 out of every 3,500 boys get MD, and one out of every 50 million girls get MD.
MD is an inherited disorder. What causes MD is when certain genes that make proteins that protect muscle fibers are defective.
Symptoms include progressive muscle weakness, walking on toes, muscle pains, large calf muscles, trouble running/jumping etc.
How to test/diagnose someone for MD? Muscle biopsy's, enzyme tests and heart-monitoring tests.
There isn't anyway to actually cure MD, but you can take corticosteriods, heart meds if the MD has affected the heart or therapy like exercising or braces.
There is also no way to prevent MD but you can go to a genetic councilor, which can tell you your risk of passing it on to your children.
