Oculopharyngeal viii. Distal ix. Emery-Dreifuss Two, out of nine major types of this Muscular Dystrophy, Myotonic and Duchenne is the most common form of the disorders. Below are the differences I’ve found to have a better understanding of the disorder; MYOTONIC (Steinert’s disease) | DUCHENNE | * Most common form of MD in Adults | * Most common form of MD in Children | * Affects both Men and Women | * Affects only Males | * Appears any time from early childhood to adulthood | * Appears between the age of 2 and 6 years old | * In rare cases, it appears in newborns (Congenital MMD) | * Muscles decrease in size and grow weaker over time yet may appear larger | * The symptom usually worse in cold temperatures | * Many people with Duchenne need a wheelchair by the age of 12 years old | * Causes muscle weakness and also affects the central nervous system, heart, gastrointestinal tract, eyes, and hormone-producing glands | * The arms, legs, and spine become progressively deformed, and there may be some cognitive impairment. Severe breathing and heart problems mark the later stages of the disease. | * Have a decreased life expectancy | * Usually die in their late teens or early 20’s | The other five, out of nine types of Muscular Dystrophy disorder are listed as below; i.
