What Are Muscular Dystrophy?

Decent Essays
What is Muscular dystrophy Muscular dystrophy is a combination of diseases passed down through genes identified by progressive degeneration of the skeletal or voluntary muscles.(Alicia Foose,PhD, Patricia Ardovino,PhD,2008, p.141). This occurs due to mixture of hypertrophy, atrophy, and necrosis muscle cells. The muscle fibers increase in muscle size and results in muscle weakness while the muscle undergoes necrosis, fat and connective tissue replace the muscle fibers.(Sheila Grossman, Carol Mattson Porth,p.461).There are nine types of muscular dystrophy according to Alicia Foose, and Patricia Ardovino“Duchenne, Becker, Emery-Dreifuss, Limb-girdle, facioscapulohumeral, myotonic, oculopharyngeal distal, and congenital.”Each disease…show more content…
Due to this males are more susceptible to getting this disease because the duchenne gene is founded in the X chromosome which causes eight out of ten males to have DMD.(Alicia Foose,PhD, Patricia Ardovino,PhD,2008, p.141) It affects girls in very rare cases. DMD is hereditary and happens when a female has one normal X chromosome and one X chromosome that has the Dystrophin gene.This is why females are more than likely to not get the disease and why they are carriers of it. Most of the time females that are carriers show no symptoms and don’t even know themselves that they are carrying around the Dystrophin gene. Symptoms, and treatment Symptom onset is in early childhood, usually between ages 3 and 5.(MDA fighting muscle disease). They usually use a nervous system complete test to look for cardiomyopathy,arrhythmia, scoliosis,enlarged muscles, loss of muscle mass, muscle contractions, muscle deformity and respiratory disorders. The tests the use includes EMG,Genetic tests, CPK and Muscle biopsy. (Chad Haldeman,2014)
Some of the symptoms are; “Fatigue, Learning difficulties,Intellectual disability, and Muscle weakness.” as stated by Chad Haldeman. DMD affects the physical domain because it weakens the muscles. It begins severely in the legs and pelvis area and less severely in the arms , neck and other areas of the body.( Chad Haldeman,2014). It’ll affect the everyday movement of people along with affecting
