Muscular_Dystrophy

Muscular Dystrophy At least 1 in 3000 people is affected by a serious inherited neuromuscular disorder; muscular dystrophy makes up an appreciable amount of these. (Azofeifa,1995) Muscular Dystrophy is a heterogeneous group of inherited disorders characterized by progressive muscle wasting and weakness. There are six types of muscular dystrophy: Duchenne muscular dystrophy (DMD), Becker muscular dystrophy, Limb girdle, fasioscapulohumeral, distal, and oculopharyneal. Duchenne type muscular dystrophy (also known a Meryon's disease) is the most common form of dystrophy. It mainly only effects boys because it is inherited as an X linked recessive trait. It is probably the most serious form of dystrophy there is because it causes most boys to start using a wheel chair by the age of 12 and causing them to die by there 20's. This disease causes some of the boys to have some degree of intellectual impairment. ( Kunkle, 1985) (Murray,1982) Becker type muscular dystrophy is a lot alike with Duchenne but milder. The onset of this does not occur until they're teenage years and early 20's. Later in life they may lose the ability to walk, but they live until their middle ages and beyond (Murray,1982) Over the past couple of years disease, dystrophy, ms, muscular, because, children, van, people, muscle, inherited, chromosome, child, 1997, wheel, time, one, help, genet, gene, emery, dna, cases, boys, been, autosomal, type, need, limb, life, jmed, girdle, et, de, chair, carriers
