Muscular dystrophies are a group of genetic disorders that result in muscle weakness over time. Each type of muscular dystrophy is different from the others.

Families are at the heart of MDA's mission. A caring and concerned group of families started MDA in 1950, and we continue to relentlessly pursue our promise to transform the lives of people living with muscular dystrophy, ALS and related neuromuscular diseases, through research, care and advocacy.
