FAQ: How Does Duchenne Muscular Dystrophy Afftect The Bodys Anatomy?

How is the body affected by muscular dystrophy?

Muscular dystrophy is a group of inherited diseases that damage and weaken your muscles over time. This damage and weakness is due to 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.

How does muscular dystrophy affect the skeletal system?

Muscular dystrophy ( MD ) refers to a group of more than 30 genetic diseases that cause progressive weakness and degeneration of skeletal muscles used during voluntary movement.

What muscles does muscular dystrophy affect?

In the early stages, DMD affects the shoulder and upper arm muscles and the muscles of the hips and thighs. These weaknesses lead to difficulty in rising from the floor, climbing stairs, maintaining balance and raising the arms.

Does muscular dystrophy affect the whole body?

The disease causes muscle weakness and also affects the central nervous system, heart, gastrointestinal tract, eyes, and hormone-producing glands. In most cases, daily living isn’t restricted for many years. Those with myotonic MD have a decreased life expectancy.

How fast does Muscular Dystrophy progress?

Patients with tibial muscular dystrophy usually begin developing symptoms between the ages of 40 and 60. The disease progresses slowly, with many patients experiencing mild mobility problems later in life. Life expectancy is not thought to be affected by this form of muscular dystrophy.

Who carries the gene for muscular dystrophy?

Inheriting muscular dystrophy. You have two copies of every gene (with the exception of the sex chromosomes). You inherit a copy from one parent, and the other copy from the other parent. If one or both of your parents has a mutated gene that causes MD, it can be passed on to you.

How old is the oldest person with muscular dystrophy?

The oldest DMD patient he knows is a 54-year- old man in the Netherlands, who had two brothers with Duchenne; one died at 15, the other at 41.

What are the 30 types of muscular dystrophy?

There are 30 different types of muscular dystrophy that are classified into nine categories. These categories are Becker, Congenital, Duchenne, Distal, Emery-Dreifuss, Facioscapulohumeral, Limb-Girdle, Myotonic, and Oculopharyngeal.

What is the most common neuromuscular disease?

The most common of these diseases is myasthenia gravis, an autoimmune disease where the immune system produces antibodies that attach themselves to the neuromuscular junction and prevent transmission of the nerve impulse to the muscle.

Is muscular dystrophy a death sentence?

Children with DMD are unable to produce dystrophin – a protein absolutely essential for muscle strength and function. As a result, every skeletal muscle in the body deteriorates over time and the disease is 100% fatal.

What race is muscular dystrophy most common in?

It appears that DMD is significantly more common in white males than in males of other races.

What is the average lifespan of someone with Duchenne muscular dystrophy?

The life expectancy for people with Duchenne muscular dystrophy is late teens or early 20s.

What is the first symptom of facioscapulohumeral muscular dystrophy?

Facial weakness is often the first sign of FSHD. It may not be noticed right away by people with FSHD and usually is brought to their attention by somebody else. The muscles most affected are those that surround the eyes and mouth.

What are the symptoms of distal muscular dystrophy?

Typically, the first symptom of distal muscular dystrophy (DD) is weakness in the distal muscles — those farthest away from the hips and shoulders such as those in the hands, feet, lower arms or lower legs. With time, other muscle groups may become affected as well. Intellect isn’t affected in this disease.

Can you get muscular dystrophy in your 50s?

It can affect anyone from teenagers to adults in their 40s. Distal muscular dystrophy affects the muscles of the arms, legs, hands, and feet. It usually comes on later in life, between ages 40 and 60. Oculopharyngeal muscular dystrophy starts in a person’s 40s or 50s.
