Myotonic dystrophy is a relatively common type of muscular dystrophy, associated with a variety of systemic complications. 3 It presents mostly in males; however, some women carriers of the gene may present muscular or cardiac pathology. This type of muscular dystrophy likewise more typically impacts young boys, according to iytmed.com. Some forms of congenital muscular dystrophy are associated with decreased mental function. It is the result of defects in the production of a protein called dystrophin, found in the muscle fibers.

DMD is the most common neuromuscular disorder in childhood with an incidence of between 1:3500 to 1:4500 male births. Becker muscular dystrophy is similar to Duchenne muscular dystrophy, but it’s less severe. Despite significant medical advances provided to DMD patients over the past 2 decades, there . The objective of this study was to determine survival, age at death and causes of death in patients with the adult-onset type of myotonic dystrophy. Long term follow-up is difficult because of the slow progression. The most well known of the muscular dystrophies is Duchenne muscular dystrophy (DMD), followed by Becker muscular dystrophy (BMD).
