Muscular dystrophy causes progressive weakness and loss of muscle mass.

It’s caused by mutated genes that interfere with the production of the proteins needed to form muscle.

There are many different kinds of muscular dystrophy. Symptoms of the most common variety begin in childhood, while other types, such as myotonic muscular dystrophy 1 (DM1) don’t occur until adulthood.

Some muscular dystrophy patients may have trouble breathing or swallowing, and some lose the ability to walk.

There is no cure, but medications and therapy can help manage symptoms and slow the course of the disease.
