Muscular dystrophy (MD) is a genetic disorder causing progressive weakness and loss of muscle mass. Mutated or abnormal genes hinder protein production needed to form healthy muscles. There are over 30 types of this condition, the symptoms of the most common variety like Duchenne Muscular Dystrophy begin in childhood mainly for boys. However, depending on the type, the age of onset, its severity, and pattern of affected muscles, vary. All forms of MD worsen eventually as muscles progressively degenerate and weaken while many people lose their ability to walk. Some types of MD also affect the heart, lungs, gastrointestinal system, endocrine glands, spine, eyes, brain, or other organs. While there is no cure for muscular dystrophy, medications, and therapy help manage the symptoms and slow the course of the disease.
