Muscular Dystrophy

Muscular dystrophy is a group of inherited, progressive muscle disorders. All forms of muscular dystrophy cause progressive weakness and degeneration of the muscles that control movement. Some also affect the heart muscle or other organs. Age of onset is between infancy to adulthood. The most common form is called Duchenne dystrophy. Other forms include Becker (a milder form than Duchenne) and myotonic muscular dystrophy, which can have its onset in late adulthood.
