Where is muscular dystrophy most common?
Duchenne MD (DMD)
- DMD is the most common and severe form of MD among children, and it accounts for approximately half of MD cases.
- DMD occurs mostly in boys, usually between 3 and 5 years of age, and progresses rapidly.
- Muscle weakness usually begins in the upper legs and pelvis.
Where can Muscular Dystrophy be found?
Muscle weakness typically begins in the face, hip and shoulders. The shoulder blades might stick out like wings when arms are raised. Onset usually occurs in the teenage years but can begin in childhood or as late as age 50.
How are muscles affected by muscular dystrophy ( MD )?
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.
Is it normal for a child to have muscular dystrophy?
Children with limb-girdle muscular dystrophy appear normal until the school years or even into young adulthood. Weakness develops first in the muscles close to the trunk–around the shoulders and hips. Most can walk until about age 30. Enlargement of the calf muscles is also common in this condition. Intellectual growth is normal.
Can a person with muscular dystrophy have heart problems?
When a muscular dystrophy patient also has facial stiffness and situations such as waking up with dry or burning eyes, this may be a sign that the patient’s eyelids were not fully closed for the whole duration of rest. As the heart itself is a muscle, developing heart problems are not unheard of when a patient has muscular dystrophy.
How is muscular dystrophy treated in the United States?
How is muscular dystrophy treated? So far, there is no cure for the muscular dystrophies. Aggressive treatment is important to prevent and manage complications. This may include physical therapy and nutritional support. Meanwhile, scientists are searching for a cure or at least for ways to slow progression.
How many people are affected by Duchenne muscular dystrophy?
Summary Duchenne muscular dystrophy (DMD) is a rare muscle disorder but it is one of the most frequent genetic conditions affecting approximately 1 in 3,500 male births worldwide.
What are the different types of muscular dystrophy?
Muscular dystrophies are a group of genetic conditions characterized by progressive muscle weakness and wasting (atrophy). The Duchenne and Becker types of muscular dystrophy are two related conditions that primarily affect skeletal muscles, which are used for movement, and heart (cardiac) muscle.
Who are women at risk for muscular dystrophy?
Females who carry a DMD gene mutation also have an increased risk of developing heart abnormalities including cardiomyopathy.

How old can a person with Becker muscular dystrophy live?
These heart problems worsen rapidly and become life-threatening in most cases. Males with Duchenne muscular dystrophy typically live into their twenties, while males with Becker muscular dystrophy can survive into their forties or beyond.
