What are the treatments for Becker muscular dystrophy
Becker's muscular dystrophy
Becker muscular dystrophy is an X-linked recessive inherited disorder characterized by slowly progressing muscle weakness of the legs and pelvis. It is a type of dystrophinopathy. This is caused by mutations in the dystrophin gene, which encodes the protein dystrophin. Becker muscular dystrophy is related to Duchenne muscular dystrophy in that both result from a mutation in the dystrophin gene.
Full Answer
What is Becker muscular dystrophy (BMD)?
Summary Summary. Becker muscular dystrophy (BMD) is an inherited condition that causes progressive weakness and wasting of the skeletal and cardiac (heart) muscles. It primarily affects males.
What medications are used to treat Becker muscular dystrophy?
Medications are given to treat symptoms that are commonly present in Becker muscular dystrophy like cardiac medications for heart disease. Corticosteroid medications are used to help patient remain able to walk for as long as possible by delaying the inflammatory process. There is no cure for Becker muscular dystrophy.

Sveen ML, Jeppesen TD, Hauerslev S, et al. Endurance training improves fitness and strength in patients with Becker muscular dystrophy. Brain2008;131:2824-31.
Is Becker muscular dystrophy X-linked or recessive?
Becker muscular dystrophy is inherited in an X-linked recessive manner. A condition is considered X-linked if the mutated gene that causes the condition is located on the X chromosome, one of the two sex chromosomes. In males (who have only one X chromosome), one mutated copy of the gene in each cell is enough to cause the condition.

There is not a cure for Becker muscular dystrophy at present. A doctor may prescribe steroid medications to help individuals remain able to walk for as long as possible. The clinical course of Becker muscular dystrophy is variable.
What is the most effective treatment for muscular dystrophy?
Corticosteroids, such as prednisone and deflazacort (Emflaza), which can help muscle strength and delay the progression of certain types of muscular dystrophy.
How does Becker muscular dystrophy work?
What Causes Becker Muscular Dystrophy? In Becker MD, muscles weaken because dystrophin (dis-TRO-fin), a protein made by muscle cells, doesn't work as it should. A change in the dystrophin gene makes the protein too short. The flawed dystrophin puts muscle cells at risk for damage with normal use.
Are there treatment options for muscular dystrophy?
There's currently no cure for muscular dystrophy (MD), but a variety of treatments can help to manage the condition. As different types of MD can cause quite specific problems, the treatment you receive will be tailored to your needs.
How does physical therapy help muscular dystrophy?
Physical therapists work with children who have muscular dystrophy to prevent or reduce joint contractures, maintain or improve cardiorespiratory and muscle strength, adapt activities or the child's home or school environments to promote movement and mobility skills, and increase daily activities, which encourage ...
Has there been any recent breakthroughs in treatment for MD?
Using an advanced gene editing technology called CRISPR, our team of scientists at UT Southwestern has been able to stop the progression of Duchenne muscular dystrophy in animals and human cells – a breakthrough that could ultimately change the prognosis for the most common fatal genetic disease in boys.
Can you live a normal life with BMD?
If the cardiac aspects of the disease are minimal, or if they are adequately controlled through medical intervention, a normal or nearly normal life span can be expected. Patients with BMD usually live at least 30 years.
What is the difference between DMD and BMD?
Condition: Duchenne muscular dystrophy (DMD) is a genetic disease that causes progressive muscle weakness and damage. Becker muscular dystrophy (BMD) is the less severe, and less common, form of the disease. Background: Signs of DMD generally appear before age six; BMD usually appears after eight years of age.
Can you prevent Becker muscular dystrophy?
There is no known cure for BMD, or treatment to stop the muscles from weakening. The goal of treatment is to keep muscles as strong as possible to allow a child to function independently. Your healthcare provider may advise genetic counseling. You can discuss with a counselor the risk of BMD in a future pregnancy.
What is Becker's disease?
Benign pseudohypertrophic muscular dystrophy; Becker's dystrophy. Becker muscular dystrophy is an inherited disorder that involves slowly worsening muscle weakness of the legs and pelvis. Tendons connect muscles to their bony origins and insertions.
Can gene therapy cure muscular dystrophy?
So far, there is no effective treatment for deteriorating muscle function in DMD patients. A promising approach for treating this life-threatening disease is gene transfer to restore dystrophin expression using a safe, non-pathogenic viral vector called adeno-associated viral (AAV) vector.
Can muscular dystrophy be cured by physical therapy?
Although there's no cure for muscular dystrophy, and no treatment can reverse the damage it causes to muscles, there are approaches that can help you or your child manage some of the symptoms. These therapies can also help you maintain your quality of life and ability to perform day-to-day tasks.
How to minimize BMD?
There are several ways to minimize and postpone contractures. Range-of-motion exercises, performed on a regular schedule, help delay contractures by keeping tendons from shortening prematurely .
What is the best treatment for BMD?
Medications that lessen the workload on the heart are sometimes prescribed for BMD. There’s some evidence that treatment with angiotensin converting enzyme (ACE) inhibitors and beta blockers can slow the course of cardiac muscle deterioration in BMD if the medications are started as soon as abnormalities on an echocardiogram (imaging of the heart) appear, but before symptoms occur. It has been shown that early treatment with perindopril delayed the onset and progression of prominent left ventricle dysfunction in children with DMD. 1
What is the name of the device that supports the ankle and foot?
Braces, scooters, and wheelchairs. Braces, also called orthoses, can support just the ankle and foot or extend over the knee. Ankle-foot orthoses are sometimes prescribed for night wear to keep feet from pointing downward and keep the Achilles tendon stretched. (Orthoses also are known as orthotics .)
What is the impact of muscular dystrophy?
Contractures. As muscle deteriorates, a person with muscular dystrophy often develops fixations of the joints, known as contractures. If not treated, these can become severe, causing discomfort and restricting mobility and flexibility. The impact of BMD can be significantly minimized by keeping the body as flexible, upright, and mobile as possible.
What is the procedure to treat contractures in the lower leg?
When contractures have advanced, surgery may be performed to relieve them. A tendon release procedure, also called heel cord surgery, can treat ankle and other contractures while a person is still walking.
Why is it important to know about BMD?
It's important that the surgical team know about that a patient has BMD so that complications can be avoided or quickly treated.
Can you get a cardiac transplant with BMD?
Cardiac transplantation may be offered as an option to patients with BMD with severe cardiomy opathy and limited or skeletal (voluntary) muscle disease. Carriers of BMD also are at higher-than-average risk of developing cardiomyopathy.
