Myotonic dystrophy, like other kinds of muscular dystrophy, causes gradual muscle loss and wastage. However, the smaller muscles, such as those in the face, jaw, and neck, are frequently the first to be affected. Myotonic dystrophy can develop at any age, from infancy to old life. Although the disease may appear mild at first, it often progresses steadily until a point where basic daily activities become difficult or impossible to perform. There is no treatment for myotonic dystrophy; however, some medications may help control symptoms or prevent further damage to muscles.
