1. Muscular dystrophy is not a name for one disease
As medically fancy as it may sound, muscular dystrophy is not a term used to refer to a single ailment. It’s an umbrella term used to describe progressive diseases that cause muscle weakness and loss of muscle mass.
The most common type of muscular dystrophy is Duchenne muscular dystrophy that affects individuals early in their childhood. It is the most severe form of muscular dystrophy with patients known only to survive until their 20s to 30s.
