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