Duchenne Muscular Dystrophy: Causes, Symptoms, and Treatment

Medically reviewed by Harsha Moole, MD, Internal Medicine. Last reviewed: October 23, 2026.

What kind of doctor treats Duchenne Muscular Dystrophy?

A pediatric neurologist, a doctor who treats nerve and muscle problems in children, often leads care for Duchenne muscular dystrophy. Heart and lung doctors often join the team. A geneticist, a doctor who knows inherited conditions, can explain how it runs in families. A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.

What is Duchenne muscular dystrophy?

Duchenne muscular dystrophy is an inherited disease. It causes muscle weakness that quickly gets worse. It is a form of muscular dystrophy, a group of genetic diseases that weaken the muscles. Other types, such as Becker muscular dystrophy, get worse much more slowly. Duchenne occurs in about 1 out of every 3,500 male infants.

Symptoms

Symptoms most often appear before age 6. Most boys show no symptoms in the first few years of life.

  • Muscle weakness that starts in the legs and pelvis, and also affects the arms and neck.
  • Problems with running, hopping, and jumping.
  • Frequent falls.
  • Trouble getting up from lying down or climbing stairs.
  • Learning difficulties.
  • Tiredness.

The calf muscles may look larger around age 4 or 5. The ability to walk may be lost by age 12, and the child will have to use a wheelchair. A weak heart muscle, called cardiomyopathy, can cause shortness of breath, tiredness, and swelling of the feet. Weak breathing muscles can cause problems breathing. Breathing problems and heart disease usually start by age 20.

Causes and who gets it

Duchenne is caused by a changed gene for dystrophin, a protein in the muscles. Muscle cells without enough dystrophin become damaged. The damaged fibers weaken and die over time. The gene is on the X chromosome, and the condition is inherited in an X-linked recessive pattern. This is why it affects boys. The sons of women who are carriers each have a 50% chance of having the condition. The daughters each have a 50% chance of being carriers. Very rarely, a female can have symptoms. It often occurs in people without a known family history. Having a family history of Duchenne is a risk.

How doctors diagnose it

Doctors start with an exam of the nerves, heart, lungs, and muscles. Tests may include:

  • A blood test for creatine kinase, an enzyme that damaged muscles can release.
  • Genetic tests.
  • A muscle biopsy, which checks a small sample of muscle.
  • Electromyography, which checks how muscles respond to nerve signals.
  • Heart tests such as an electrocardiogram.
  • Pulmonary function tests, which are breathing tests.
  • X-rays of the spine to look for scoliosis, a curve in the spine.

Treatment

There is no known cure for Duchenne muscular dystrophy. Treatment aims to control symptoms to improve quality of life. Steroid medicines can slow the loss of muscle strength. Steroids and lack of activity can lead to extra weight gain. Activity is encouraged, and bed rest can make the muscle condition worse.

Other care can include physical therapy, speech therapy, braces, and wheelchairs. Some people need help breathing during the day or night. Heart medicines may be used to help the heart work. Some people have spine surgery for a curve that keeps getting worse. Genetic therapies may help certain people, depending on the genetic cause. Each one works on only a small number of people. They raise dystrophin, but they have not yet been shown to have significant clinical benefits. Some other treatments, such as amino acids, coenzyme Q10, creatine, fish oil, and vitamin E, have been tried, but their effects have not been proven. New treatments are being studied in trials.

When to see a doctor

Contact your child's health care provider if your child has symptoms of Duchenne muscular dystrophy. Also call if symptoms get worse or new symptoms start, especially fever with cough or breathing problems. Call 911 or go to the emergency room if your child has chest pain, faints, or has severe trouble breathing.

How a direct primary care or concierge doctor fits in

A direct primary care doctor charges a flat monthly fee instead of billing insurance, while a concierge doctor usually charges more and often works alongside insurance. Such a doctor can do a first evaluation and help line up referrals. They can also help coordinate the mix of therapies that care usually involves.

Common questions

Is there a cure for Duchenne muscular dystrophy?

No, there is no known cure. Treatment aims to control symptoms to improve quality of life.

Does Duchenne muscular dystrophy affect girls?

It almost always affects boys. Very rarely, a female can have symptoms if she has the changed gene. Female carriers may have muscle weakness and cramping. They also have a higher risk of heart problems.

Can Duchenne muscular dystrophy affect the heart?

Yes, it can weaken the heart muscle. Signs can include shortness of breath, tiredness, and swelling of the feet. Doctors use heart tests, such as an electrocardiogram, to check it.

Can Duchenne muscular dystrophy be found before birth?

Yes, it can be found during pregnancy. People with a family history may want genetic counseling.

How long do people with Duchenne muscular dystrophy live?

Males with Duchenne typically live into their twenties. Advances in supportive care have resulted in many men living to age 35 years.
