The History Of Dmd Stemmed From The Progressive Muscular Dystrophy

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.

Attention Getter: Nowadays, with the development of the technology in the medical industry, human health condition is getting better. There are so many different medicine, vitamin are used for improving the human immunes systems to fight against diseases. But there are still some dangerous disease that can not be cured yet and Muscular Dystrophy Disease is one of them.

Listener Relevance: Duchenne Muscular Dystrophy (DMD), is more common than people think and chances are sooner or later you will know of or see somebody affected by this disease.

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 (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.

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 is a sex-linked disease, which is inherited in a recessive fashion (National Human Genome Research Institute, 2013). Over thirty similar genetic disorders exist (Duchenne Foundation Australia, 2015). All types of muscular dystrophy are considered to be a rare disorder (Duchenne Foundation Australia, 2015). Duchenne Muscular Dystrophy is most common in children and causes muscle weakness and wasting, which commonly begins in the lower limbs (Duchenne Foundation Australia, 2015; National Human Genome Research Institute, 2013). The disease itself is caused by changes to the DMD gene, which is responsible for providing instructions regarding the creation of the dystrophin protein in one’s muscles (Duchenne Foundation Australia, 2015). This protein is responsible for protecting muscles from damage, and without it the cells of a person’s muscles deteriorate and symptoms of Duchenne Muscular Dystrophy are exhibited (Duchenne Foundation Australia, 2015). The disease results from changes in the DMD gene, or other genetic changes in a child (Duchenne Foundation Australia, 2015).

(Chad Haldeman-Englert, 2014) The symptoms usually appear before age 6 and may appear as early as infancy. One of the first noticeable symptom of this disease is the delay in motor milestones; many with Duchenne will take longer to independently stand, sit or walk than average child. (National Human Genome Research Institute, 2013) In toddlers, their enlarged calf muscles causing them to frequently fall over whilst moving. The child may experience occasional pain in the calves and may have some difficulty raising their arms. There is a steady decline in muscle strength between the ages of 6 and 11 years. Most boys are confined to a wheelchair by the age of 12. Muscular weakness and skeletal deformities often leads to respiratory issue. The diaphragm and other muscles that operates the lungs may start to weaken, making it hard to circulate fresh air into the body. The risk of serious respiratory infection is very high. Cardiomyopathy, a chronic disease of the heart muscle that is often a result of the DMD. Most boys will develop this heart disease in their early teens. One third of boys with DMD have some degree of learning disability. Majority of their learning problems occurs in focusing, verbal learning and memorising, and personal interaction. (The Muscular Dystrophy Association (MDA), 2016) Some of the symptoms, such as respiratory infection and cardiomyopathy are common causes of death in DMD

Even though the annual telethon is over, muscular dystrophy—all nine forms—still exists. MD presents with a combination of muscle weakness and muscle wasting.

Duchenne’s muscular dystrophy (DMD) is a progressive genetic disorder that leads to muscle atrophy and eventually death. Diagnosing DMD consists of blood tests, genetic testing, and muscle biopsies. Signs and symptoms begin presenting in toddlers with DMD and progressively worsen throughout life. There is no cure for DMD, and will cause terminal cardiopulmonary complications. Medical interventions consist of corticosteroid treatment, respiratory management, cardiac management, psychological management, and physical therapy interventions.

Muscular dystrophy (MD) is a genetic disorder caused by incorrect or missing genetic information that leads to the gradual weakening of the muscle cells. Various causes lead to weak and deteriorating muscles depending on the type of muscular dystrophy the patient was affected by. However, there are many causes for muscular dystrophy due to the fact that there are thirty forms of muscular dystrophy, which are categorized under several categories. All are ultimately caused by autosomal recessive, autosomal dominant, sex-linked, and random mutations in very rare cases.

Duchenne Muscular Dystrophy is one of the most severe yet common cases of Muscular Dystrophy that occurs mainly in boys of younger age. Guillaume Benjamin Amand Duchenne, who was a French neurologist, was the first to discover this disorder in the 1860s (Emery, 2008, pp. 25). This disease is an X-linked disorder which affects the skeletal system, and causes rapid muscular weakness and heart muscle problems. It’s stated that 1 out of every 3,600 males will be diagnosed with Duchenne Muscular Dystrophy (Bushby, 2009, pp.1). According to the Muscular Dystrophy Association, symptoms usually begin to show between the ages of 3 to 5 years old. (pp. 1) Some of the symptoms may include delayed in walking, regularly falling, learning difficulties,

Duchenne Muscular Dystrophy or DMD for short is a genetic disease that affects the skeletal muscles causing muscle degeneration and muscle wasting. Duchenne Muscular Dystrophy is an X-linked recessive chromosomal disease, which is caused by mutations in the DMD Gene (Regenerative Medicine). This Disease affects 1 in 3600 boys (Regenerative Medicine). A male born with this disease experiences respiratory dysfunction, trouble ambulation, cognitive impairment, some even experience premature death. Unfortunately, there is no cure for DMD, but there are research studies in the works for different therapies to help reverse this gene mutation and to elevate symptoms associate with this disease.
