14128 Muscular Dystrophy
Informed by recognized medical guidance
Overview
Muscular dystrophy is a group of rare, long-lasting conditions that cause muscles to weaken and lose tissue over time. It is caused by changes in genes that affect muscle-building proteins. There are many types, and each one can affect different muscles and progress at different speeds.
Key facts
- Muscular dystrophy is not one disease but a group of related conditions.
- It mainly affects voluntary muscles, like those in the arms, legs, and sometimes the heart.
- There is no cure yet, but treatment can help manage symptoms and improve quality of life.
- Most types are inherited, but some can happen without a family history.
Muscular dystrophy is rare. In the UK, about 1 in 3,000 people have some form of it. Duchenne muscular dystrophy is the most common type in children.
It can affect people of all ages. Some types appear in early childhood, while others only start in adulthood. It affects both boys and girls, although certain types, like Duchenne, are much more common in boys.
Symptoms
- Sudden or severe difficulty breathing, wheezing, or choking on saliva or food
- Chest pain, fainting, or severe dizziness
- Sudden inability to move a limb or a sudden severe drop in muscle strength
- ⚠New difficulty swallowing that makes it hard to eat or drink safely
- ⚠Worsening weakness that interferes with walking, breathing, or daily activities
- ⚠Pain or tingling that comes on suddenly and does not go away
Common symptoms
- Progressive muscle weakness, often starting in the hips, shoulders, arms, or legs
- Trouble walking, climbing stairs, running, or rising from the floor
- Frequent falls and poor balance
- Muscle pain, stiffness, or cramping
- Limited range of motion in joints
- Difficulty with swallowing or breathing (in later stages or certain types)
Symptoms in children
- Delayed motor milestones, such as sitting, standing, or walking
- Walking on tiptoes or waddling
- Enlarged calf muscles (pseudohypertrophy)
- Difficulty jumping, running, or getting up from the floor
- Learning difficulties (with some types)
Symptoms in older adults
- New weakness in the arms or legs that gets worse over time
- Trouble with everyday tasks like lifting objects or getting out of a chair
- Falls and difficulty with balance
- Swallowing problems or breathing difficulties
- Heart rhythm issues or palpitations (in some types)
Causes
Main causes
- Muscular dystrophy is caused by changes (mutations) in genes that help make proteins needed for healthy muscle structure. Without these proteins, muscle cells gradually break down and are replaced by scar tissue and fat.
- The specific gene change determines the type of muscular dystrophy, how severe it is, and which muscles are affected.
Risk factors
- Having a family history of muscular dystrophy is the main risk factor.
- Some types can also occur as a new gene change in a person with no family history.
- The sex of the child can be a risk factor for certain types — for example, Duchenne and Becker muscular dystrophy mostly affect boys.
When to see a doctor
See a doctor urgently if:
- If you or your child have sudden or rapidly worsening muscle weakness, call your GP or local out-of-hours service the same day.
- If breathing or swallowing becomes difficult, go to a hospital emergency department or call your local emergency number.
Book a routine appointment if:
- If a child seems delayed in motor skills (like not walking by the expected age), make an appointment with your GP.
- If you notice ongoing muscle weakness, falls, or trouble climbing stairs, see a doctor for an assessment.
- If you have a family history of muscular dystrophy and are planning a family, ask your GP about genetic counselling.
Diagnosis
To diagnose muscular dystrophy, a doctor will review symptoms, ask about family history, and do a physical exam. They will check muscle strength, reflexes, and range of motion. If muscular dystrophy is suspected, they will refer you to a specialist — usually a neurologist at a neuromuscular clinic.
Tests that may be done
- Blood test for creatine kinase (CK) — a muscle enzyme that leaks into the blood when muscle is damaged
- Genetic testing to look for specific gene changes
- Muscle biopsy — a small sample of muscle is taken and examined under a microscope
- Electromyography (EMG) — a test that measures the electrical activity of muscles
- Heart tests (like ECG) and breathing tests to check for lung and heart involvement
What to expect at your appointment
Getting a diagnosis can take time and may involve several tests. You will meet a team of healthcare professionals, including specialist nurses, physiotherapists, and genetic counsellors. They are there to support you, explain the results, and help you plan the next steps.
Treatment
There is no cure for muscular dystrophy, but treatment can slow progression, manage symptoms, and help you stay active and independent. A team of specialists will work with you to create a personal care plan.
Self-care at home
- Gently stretch muscles each day to keep them flexible and reduce contractures
- Stay active with low-impact exercises like swimming, cycling, or seated exercises
- Use mobility aids (e.g., braces, walkers, wheelchairs) when needed to stay safe
- Eat a balanced diet to maintain muscle tissue and energy
- Rest when you need to, and avoid pushing your muscles to fatigue
Medical treatments
Medical treatment may include physiotherapy to keep muscles working, splints or braces to support joints, breathing support such as a ventilator (if lungs are affected), and medicines to help the heart or bone health. Some newer gene-targeted therapies are now available for certain types of muscular dystrophy. Your specialist will explain what options might be suitable for your situation, and the benefits and risks of each.
When is surgery considered?
Surgery may be considered in some cases, such as releasing tight joints or correcting curves in the spine (scoliosis), which can improve comfort and function. Surgery for muscular dystrophy is always discussed thoroughly with the care team and the person and their family.
Living with this condition
Living with muscular dystrophy means adapting to changing abilities over time. An occupational therapist can help you make your home safer and easier to get around — for example, with ramps, rails, or special equipment. Planning your day and pacing yourself helps you save energy for what matters most.
Lifestyle tips
- Stay connected with friends, family, and peer support groups
- Take breaks and pace your activities to avoid overexertion
- Use assistive technology, such as voice-activated tools or adapted keyboards, if hand weakness makes things hard
- Talk openly with your care team about any physical or emotional challenges
Diet and exercise
A balanced diet with enough protein, vitamins, and calories helps maintain muscle and energy. Gentle exercise like swimming or seated stretching can improve flexibility and mood. Always check with your care team before starting a new exercise routine, and avoid activities that strain your heart or lungs.
Mental health and emotional wellbeing
Living with a long-term muscle condition can be stressful and may lead to anxiety or low mood. You are not alone, and speaking to a counsellor, psychologist, or trusted friend can help. If you ever have thoughts of self-harm, reach out for crisis support right away — call your local emergency number or a mental health helpline in your area.
Prevention
Muscular dystrophy cannot be prevented because it is a genetic condition. However, genetic counselling can help families understand the inheritance pattern and discuss options for future family planning.
Vaccines
Talk to your doctor about keeping up with routine vaccinations, especially those that protect against flu and pneumonia, as serious infections can be harder for people with muscle weakness to fight off.
Screening programmes
Some newborn screening programmes can detect certain types of muscular dystrophy early, but this varies by country. If you have a family history, genetic testing and counselling are available.
Complications
If left untreated
- Breathing difficulties due to weak diaphragm muscles
- Heart muscle weakness (cardiomyopathy)
- Difficulty swallowing and choking
- Joint contractures (joints fixed in a bent position)
- Scoliosis (curved spine)
- More frequent falls and injuries
- Reduced independence over time
Long-term outlook
Muscular dystrophy is a serious condition, but with good medical care and support, many people live long and fulfilling lives. Treatments continue to improve, and ongoing research is opening new doors. Hope and quality of life are possible, especially with an early diagnosis, a strong care team, and a supportive community.
