Myotonic Muscular Dystrophy well known as MMD is a form of muscular dystrophy that affects muscles and many other organs in the body. Myotonic muscular dystrophy often is abbreviated as “DM” in reference to its Greek name, Dystrophia Myotonica.

Other names for this disorder include simply myotonic dystrophy and, occasionally, Steinert’s Disease, after the German doctor who originally described the disorder in 1909.

Different types of Myotonic Dystrophy have been discovered, and some of them may cause more serious problems than others.

There is currently no specific cure for Myotonic Dystrophy, but new discoveries about the disorder itself and how can the symptoms be managed and/or relieved, are coming out almost every day.
