Understanding Myotonic Dystrophy 

Myotonic dystrophy is a form of muscular dystrophy in which the muscles have difficulty relaxing. Muscle myotonia (abnormally prolonged muscle contraction, with difficulty relaxing) may develop soon after birth or begin as late as early adulthood, especially affecting the hands, wrists and tongue. 

Facts about Myotonic Dystrophy 

  • Myotonic dystrophy is part of a group of inherited disorders called muscular dystrophies. 

  • There are two major types of myotonic dystrophy: type 1 and type 2. Their signs and symptoms overlap, although type 2 tends to be milder than type 1. 

  • It is the most common form of muscular dystrophy that begins in adulthood 

  • Myotonic dystrophy affects at least one in 8,000 people worldwide and effects both males and females equally. 

  • About half of those with the disorder show visible signs by their early twenties, but a significant number do not develop clear-cut symptoms until after age 50. 

What are the symptoms of Myotonic Dystrophy?

  • Prolonged muscle contractions (myotonia) and the inability to relax certain muscles after use 

  • Slurred speech or temporary locking of their jaw 

  • Clouding of the lens of the eye (also known as cataracts) 

  • Abnormalities of the electrical signals that control the heartbeat 

  • In affected men, hormonal changes can lead to early balding and fertility issues.
