Duchenne Muscular Dystrophy Essay

1. The meaning of Duchenne muscular dystrophy is a severe form of muscular dystrophy caused by a genetic defect that can be characterized by a disturbed growth of cardiac and skeletal muscles. It usually affects boys. In 1861, a French neurologist, Guillaume B. Duchenne, was the first person to give a detailed description of this syndrome.

Boys begin to have difficulty sitting up and standing, weakness that progresses to muscles in the trunk and shoulder, and later affecting the heart muscle. By the age of twenty years individuals affected with Duchenne dystrophy die.

Duchenne muscular dystrophy was first discovered by Guillaume Benjamin Amand Duchenne in the 1860’s, but due to lack of medical knowledge little was known until the 1980’s. It was in 1986 that researchers that were supported by the MDA, muscular dystrophy association, identified the particular X-chromosome that leads to DMD, Duchenne muscular dystrophy. Dystrophin is the protein that is associated with the gene and was named in 1987.The DMD gene is the second largest gene to date, and it produces dystrophin.(Genome, 2013) Lack of the protein Dystrophin in the muscle cells causes them to weaken and become fragile. (MDA, 2015). DMD is an inherited disorder, but there are rare cases where it can spontaneously appear in a child with no previous family history due to a random mutation in moms X-chromosome. DMD is a gender specific disease that only appears in males.

Credibility Statement: According to the "Muscular Dystrophies" by Harvey B.Sarnat in Nelson Textbook of Pediatrics, 20th Ed 2016, "A muscular dystrophy is distinguished from all other neuromuscular diseases by 4 obligatory criteria: It is a primary myopathy, it has a genetic basis,

Duchenne Muscular Dystrophy is also the most common type of muscular dystrophy in kids, children who are affected by the disease will most likely be in a wheelchair by the time they are 12, and are likely to die anywhere from their late teens to early twenties ( Yiu and Kornberg, 2008, p. 236).

Individuals who inherit this disease will have a rapid progression of symptoms. Walking becomes difficult and skeletal contractures and muscle atrophy follows. They also usually need wheelchairs by adolescence. Half of the receivers of the disease unfortunately develop some form of mental retardation and most never make it past their teenage years. Currently, options for a treatment of muscular dystrophy are limited. Physical therapy may slow down the progression of deformities. Such devices as wheel chairs, crutches, or secondary orthopedic limbs may permit mobility. There are also a few medications that can help relieve pain and stiffness in the muscles. The Muscular Dystrophy Association, the Parent Project Muscular Dystrophy Research and the Children's Hospital of Pittsburgh helped fund a research project for the disease. The research, carried out by Johnny Huard, Ph.D., is looking fairly successful. Scientists are isolating special

Duchenne muscular Dystrophy (DMD) is the most common out of nine types of muscular dystrophy. This genetic disorder causes progressive muscular weakness, and deterioration due to the lack of a protein called Dystrophin. This protein keeps the muscles in tack, so when it's missing, the muscles slowly break down. (MDA, 2015)

Duchenne muscular dystrophy (DMD) is defined as a chronic form of dystrophy that is caused by a mutated gene. This essay critically discusses Duchenne muscular dystrophy as a whole, including all the symptoms, causes as well as treatment.

Even though there are no cures, there are some treatments to slow down the progression of Ben’s DMD. Ben can take certain supplements that will help him function better. One of them is beta-Hydroxy beta methylbutyric acid (HMB). This is an amino acid that helps slow down the degradation of a person’s muscles. However, this has not been studied on DMD. Haelan is another supplement that Ben can take. It will boost Ben’s immune system and give him more energy overall, which will help him live with his condition. Again, this has not been directly tested on DMD. Deflazacort is an over-the counter drug that has anti-inflammatory properties that will preserve Ben’s muscles. This has been proven to prevent/ delay scoliosis as well. Ben could also take Q-10. This is a coenzyme that many people with DMD lack. It will help his cells function

This rare disease affects 1 in 3,500- 6,000 males. A key indicator a child has Duchenne is muscle weakness. This means a child may have difficulty getting up after sitting down and difficulty walking. Often times kids with Duchenne are walk on there toes and can

According to the MediLexicon Medical Dictionary, muscular dystrophy is defined as a general term for a number of hereditary, progressive degenerative disorders affecting skeletal muscles, and often other organ systems (Staff). Basically what that means is that muscular dystrophy is a genetic disorder that is passed down that affects the skeletal muscles and other organs by slowly breaking them down. Since it is genetic, it is not contagious and you cannot catch it from someone who has it. MD weakens muscles over time, so children, teens, and adults who have the disease can gradually lose the ability to do the things most people take for granted, like walking or sitting up. Someone with MD might start having muscle problems as a baby or

Duchenne Muscular Dystrophy (also referred to as DMD) is a type of muscular dystrophy that weakens the muscles that we need to support our body, body weight, to stand, and to move around. It also can cause you to have scoliosis. Some of the main causes for DMD are genetic disorders, mutations, and DMD has to be passed down throughout everyone in that family for generations. The symptoms you can have if you have DMD are weak muscles, lack of strength, and difficulty walking. DMD is a negative mutation because it affects your muscles horribly bad that you can get a disability of walking and even moving. You need to tell your doctor immediately if you experience any symptoms. If you don't tell your doctor, you may find yourself in a very difficult situation where you can't get up or can't get something you need. When you do talk to your doctor, you will have an advantage of getting the help you need.

Usually once atrophy of the hip musculature is noticed, shoulder weakness in noticed also. Those inflicted with DMD will also have trouble with overhead activates, and keeping the shoulders flexed for long periods of time. Scott M. Giles actually lists the following muscles affected by DMD: “Shoulder girdle musculature, pectorals, deltoids, rectus abdominals, gluteals, hamstrings, and calf muscles” 6. DMD patients continue to lose control and strength in their lower extremity musculature and eventually have so much trouble walking they are confined to a wheelchair. There is not a set age where this occurs, but the average is around twelve years old. The DMD muscles involved in eating, drinking, and of the eye are not touched by the disease. They usually do not have any hearing deficits or stroke disorders 1.

muscular dystrophy has many forms and therefore symptoms can vary between the variations. Overall symptoms include the weakening of skeletal muscles and the defect and death muscle tissues. Duchenne muscular dystrophy is the most common and affects young boys such as Eddie.

Duchenne Muscular Dystrophy has the potential to be inherited from previous generations (National Human Genome Research Institute, 2013). The disease is sex-linked and inherited on the X chromosome in a recessive fashion. Males who only have one X and one Y chromosome
