Duchenne Muscular Dystrophy (DMD) is a genetic disorder, primarily affecting muscles. It is also known as pseudohypertrophic muscular dystrophy. DMD is named after Guillaume Benjamin Amand Duchenne, a 19th century French neurologist.
Some symptoms of DMD include weaknesses in the pelvis, upper limbs, heart, back and muscles around your lungs. There is also fatigue, mental retardation and difficulty with motor skills associated with the disease. These symptoms may cause frequent falling and clumsiness. Often times, the person affected faces progressive difficulty walking, and a wheelchair may be needed eventually. Despite theses muscle impairments, the person still has a fully functioning nervous system and still has the sense of touch. They also have full control over their bladder, despite weaknesses in the pelvis.
DMD is a genetic disorder, with a mutation in the X chromosome. This mutation prevents the production of the protein dystrophin. Dystrophin is a selectively permeable cell that helps muscle tissue repair itself. Missing or defective dystrophin may lead to the destruction of the cell. This is what causes DMD. DMD is a sex-linked genetic disorder. It is an X-linked recessive gene, meaning that females can be a carrier for the gene, however DMD is more common in males. DMD occurs in about 1 in every 3,600 baby boys. It is almost obsolete in females, however there are a few rare cases in which a female has DMD.
DMD is usually noticed between ages two and six.

Duchenne Muscular Dystrophy

while worsening with the effects of the environment, and chromosomal defects are caused by either a surplus or lack of genes. Although not common, Duchenne Muscular Dystrophy is a monogenic degenerative genetic disorder that causes the depletion of muscle in a person, usually male. This is a serious disorder that causes rapidly declining health…

Duchenne Muscular Dystrophy

Duchenne muscular dystrophy, also known as DMD, is a genetic disorder characterized by progressive muscle weakness and degeneration. Duchenne muscular dystrophy was first described in the 1860s by Guillaume Benjamin Amand Duchenne, a French neurologist but until the 1980s, little was known about the cause of any kind of muscular dystrophy. This disease is x-linked recessive. Approximately two-thirds of DMD occurrences are hereditary while one-third of cases are due to a new mutation. It is one of…

Duchenne Muscular Dystrophy Essay

The most commonly known name is Duchenne Muscular Dystrophy but is also known as Psuedohypertrophic Muscular Dystrophy. In the 19th century DMD was recognized as a specific disorder. In 1978-83 DMD was located on the X-Chromosome and the symptoms were identified around 1861 Duchenne Muscular dystrophy is a disease that affects all of the voluntary muscles in the body as well as the heart and breathing muscles and will eventually cause death. Usually those affected will not live past the age of 30…

Duchenne Muscular Dystrophy Research Paper

Duchenne muscular dystrophy (DMD ) is a muscle disease that includes muscle weakness and can be inherited and can gradually worsen over time. It’s caused by a defective gene and it affects more boys than girls, but the girls can be carriers for the disease. Many young infant males are affected by this disease, and, as time passes, they start to develop symptoms (University of Maryland Medical Center (UMMC), 2014). DMD is a muscular disease that is inherited and causes muscle weakness . What is…

Duchenne Muscular Dystrophy: A Case Study

Duchenne Muscular Dystrophy evolves via three essential stages: an ambulatory stage, an early nonambulatory stage and a late nonambulatory stage. In ambulatory stages, the affected children have symptoms between two and four years old. Patients have weakness of forward head flexion and a narrow ability to sit. Early in this stage, the affected children can play with their classmates, but after the second grade, they have some serious physical education requirements in which they will need help to…

Muscular Dystrohphy on Children Essay

MUSCULAR DYSTROPHY Muscular dystrophy is a genetic disorder characterized by the progressive wasting of skeletal muscles. Muscles weaken overtime and sufferers gradually lose the ability to do the things we take for granted, for example - walking. There are several forms of Muscular Dystrophy (MD), all of which can occur throughout childhood or adulthood. In this report however I will focus on two main forms – Duchenne muscular dystrophy (DMD) and Becker muscular dystrophy (BMD). Both forms of…

Duchenne Cerebral Essay

What Is Duchenne Muscular Dystrophy? What Is Duchenne Muscular Dystrophy? DMD is caused by a change in a gene responsible for making the protein dystrophin, which keeps muscles strong and healthy. This change is referred to as a mutation. When there is a mutation in this gene, the protein dystrophin does not work. The muscle cells become weak and they gradually break down. DMD usually affects boys; it is extremely rare in girls. DMD is a progressive disease. At first, the weakness is mostly…

Muscular Dystrophy Research Paper

Muscular dystrophy refers to a group of genetic (inherited) conditions that cause the body's muscles todeteriorate slowly over time, and become increasingly weak. Some of the signs and symptoms ofMuscular dystrophy are: problems with coordination and mobility with frequent falls, muscle weakness, and joint stiffness. High levels of a chemical called creatine kinase (CPK) found in the blood may alsohelp diagnose muscular dystrophy. High levels of creatine kinase don't give a definite diagnosis, sincemany…

Muscular Dystrophies

Understanding muscular dystrophies in anatomy and physiology is very essential and influential when determining the different types of diseases it carries. Muscular dystrophies are groups of different inherited diseases that causes weakness and loss of the muscle. There are over 30 many different types of muscular dystrophies that carry different types of symptoms and severity (Martel, 2015). If you’re inherited with any type of muscular dystrophies, your muscles begins to worsen, as you grow older…
