Muscular Dystrophy The most common and severe form of the disorder, called Duchenne (du-SHEN) muscular dystrophy, affects about 2 in 1,000 young boys. In the United States, it has been estimated that 40,000 boys and young men are afflicted with this form. In western Europe, an estimated 70,000 are affected.

How many people are affected with muscular dystrophy (MD)? A answered. Muscular dystrophy (MD) occurs worldwide, affecting all races. Its incidence varies, as some forms are more common than others. Its most common forms in children, Duchenne and Becker MDs, alone affect approximately 1 in every 3,500 to 5,000 boys, or between 400 and 600 live male births each year in the United States. Some types of MD are more prevalent in certain countries and regions of the world. Most MDs are familial, meaning there is some family history of the disease. This answer is based on source information from National Institute of Neurological Disorders and Stroke.

What Are Signs of Muscular Dystrophy? Duchenne muscular dystrophy accounts for approximately 50 percent of all muscular dystrophy cases. People with this type experience frequent falls, difficulty getting up from a seated position, trouble running, waddling gait and large calf muscles, states the Mayo Clinic. Patients with Becker muscular dystrophy present with similar symptoms, but they usually are slower progressing and do not appear in patients until their mid-20s or later.

Understanding Muscular Dystrophy -- the Basics Some types of muscular dystrophy affect only males; some people with MD enjoy a normal life span with mild symptoms that progress very slowly; others experience swift and severe muscle weakness and wasting, dying in their late teens to early 20s. The various types of MD affect more than 50,000 Americans.

- Muscular dystrophy is a disorder that weakens a person's muscles over time. People who have the disease can gradually lose the ability to do everyday tasks.

Overview Each form of muscular dystrophy is caused by a genetic mutation particular to that type of the disease. Many of these mutations are inherited. But some occur spontaneously in the mother's egg or the developing embryo and can be passed on to the next generation. Risk factors. Muscular dystrophy occurs in both sexes and in all ages and races.

Muscular Dystrophy Duchenne muscular dystrophy is the most common form affecting children. Myotonic dystrophy type 1 is the most common form affecting adults. Mutations can develop “de novo” and lack of family history of MD does not rule out the possibility of muscular dystrophies.

- Muscular dystrophies are a group of diseases that are passed down genetically. These diseases cause damage and weakness to muscles over time. This damage and weakness is caused by the lack of a protein called dystrophin, which is necessary for normal muscle function.The absence of this protein can cause problems with walking, swallowing, and muscle coordination.hese diseases cause damage and weakness to muscles over time.

What causes congenital muscular dystrophy? A Honor Society of Nursing (STTI) answered. All types of congenital muscular dystrophy are caused by damaged or defective genes that affect one of the various proteins in muscle cells. This leads to muscle weakness and the progressive crippling that are usually symptoms of the disease. The particular genetic mutation that causes it-and the particular protein that's affected-depends on which type of the disease you have.

Types Types of muscular dystrophy. There are many different types of muscular dystrophy (MD). All types cause muscle weakness, but the areas affected and the severity of the symptoms are different.Typical symptoms of some of the most common types of MD are explained below.Muscular Dystrophy UK also provides a dropdown list of specific muscle-weakening conditions.yotonic dystrophy. As with other types of muscular dystrophy, myotonic dystrophy involves progressive muscle weakness and muscle wasting. However, it's often the smaller muscles that are affected first, such as those in the face, jaw and neck. Myotonic dystrophy can appear at any time between birth and old age.

Duchenne Muscular Dystrophy Muscular dystrophies are a group of diseases that make muscles weaker and less flexible over time. Duchenne muscular dystrophy (DMD) is the most common type.It’s caused by flaws in the gene that controls how the body keeps muscles healthy. The disease almost always affects boys, and symptoms usually begin early in childhood. Children with DMD have a hard time standing up, walking, and climbing stairs.uscular dystrophies are a group of diseases that make muscles weaker and less flexible over time.

- Motor neurone disease is an example of an atrophy disease. Duchenne muscular dystrophy: This is a disease most common and most rapidly progressive of the childhood muscle diseases. Usually, the first sign of the disease is difficulty in walking at an early age (from 2 to 6 years).osted on. (Answer #2). There are too many diseases that effect the muscular system to mention. Many of them are brain disorders that effect the motor control areas in the frontal and parietal lobes of the brain.

- Duchenne (pronounced: due-SHEN) muscular dystrophy (DMD), the most common type of the disease, is caused by a problem with the gene that makes a protein called dystrophin (pronounced: dis-TROH-fin). This protein helps muscle cells keep their shape and strength.

Muscular dystrophy Muscular dystrophy (MD) is a group of muscle diseases that results in increasing weakening and breakdown of skeletal muscles over time. The disorders differ in which muscles are primarily affected, the degree of weakness, how fast they worsen, and when symptoms begin. Many people will eventually become unable to walk.

Types of Muscular Dystrophy and Neuromuscular Diseases What are the different types of muscular dystrophy? Muscular dystrophy is a group of inherited diseases that are characterized by weakness and wasting away of muscle tissue, with or without the breakdown of nerve tissue. There are nine types of muscular dystrophy, with each type involving an eventual loss of strength, increasing disability, and possible deformity.

- For example, Duchenne muscular dystrophy and Becker muscular dystrophy are caused by mutations in the dystrophin gene, whereas limb-girdle muscular dystrophies are caused by mutations in other genes.uchenne MD is the most common form of MD and primarily affects boys. It is caused by the absence of dystrophin, a protein involved in maintaining the integrity of muscle. Onset is between 3 and 5 years and the disorder progresses rapidly.
