Muscular Dystrophy: Complete Guide to Causes, Symptoms, Types and Treatment
Written by the Muscular Dystrophy Pakistan (MDP) content team. Based on information from NINDS, NICHD and MDA (see sources below). Last updated: October 3, 2026.
Muscular dystrophy is a group of inherited genetic conditions that cause muscles to become weaker over time. For many families in Pakistan, the name is heard for the first time only after a child has been falling often, walking late or struggling to climb stairs, sometimes after years of visits to different doctors. This guide explains muscular dystrophy in simple words: what it is, why it happens, its main types, how it is diagnosed, what care is available, and where families in Pakistan can find support.
Quick facts
Muscular dystrophy (MD) is a group of more than 30 genetic diseases.
It causes progressive muscle weakness: muscles get weaker over time.
It is not contagious and is not caused by anything parents did.
Most types have no complete cure yet, but proper medical care and monitoring make a real difference.
Early diagnosis helps families plan care and understand the risk for other family members.
What Is Muscular Dystrophy?
Muscular dystrophy refers to a group of more than 30 diseases that cause muscle weakness and loss of muscle mass. Different types affect different parts of the body and vary in how severe they are. Some forms appear in infancy or childhood, while others may not appear until middle age or later. In all forms, muscles become weaker with time.
Muscles are made of fibres that need specific proteins to stay strong. In muscular dystrophy, these fibres are easily damaged and cannot be repaired properly, so muscle tissue is gradually lost. Depending on the type, this can affect walking, standing, using the arms, swallowing, breathing and, in some types, the heart.
Muscular dystrophy is not an infection, it cannot spread from one person to another, and it is not a punishment or a curse. It is a medical condition caused by changes in genes. Understanding this removes blame and helps families focus on care.
What Causes Muscular Dystrophy?
Every protein in our body is made following instructions written in our genes. In muscular dystrophy, a change (mutation) in a gene means that an important muscle protein is missing, too little, or not working properly. For example, in Duchenne muscular dystrophy the protein dystrophin, which helps keep muscle fibres intact, is absent. In Becker muscular dystrophy, dystrophin is present but faulty or reduced, which is why Becker is usually milder.
The gene change is usually inherited. The main patterns are:
X-linked recessive: The gene is on the X chromosome. A mother can be a carrier without being seriously affected, and each son has a 50% chance of being affected while each daughter has a 50% chance of being a carrier. Duchenne and Becker follow this pattern.
Autosomal recessive: A child is affected only when both parents carry a changed copy of the gene. Parents are usually healthy. This pattern is seen in many limb-girdle and congenital types, and it is more likely when parents are blood relatives.
Autosomal dominant: One changed copy is enough to cause the condition, so an affected parent has a 50% chance of passing it to each child. FSHD and myotonic dystrophy are examples.
New (de novo) mutation: Sometimes there is no family history, and the gene change appears for the first time in the child.
Symptoms of Muscular Dystrophy
Symptoms depend on the type, the age of onset and how fast the condition progresses. Common signs include:
Muscle weakness that slowly gets worse, often starting near the hips and thighs, shoulders, or face
Frequent falls, clumsy or waddling walk, walking on toes
Difficulty running, jumping, rising from the floor or climbing stairs
Using the hands to "climb up" the legs when standing from the floor (Gowers' sign)
Enlarged-looking calf muscles in some children (due to muscle being replaced by fat and scar tissue)
Delay in sitting, standing or walking compared with other children
Muscle stiffness, tight joints, or a curved spine in some types
Drooping eyelids, swallowing difficulty or speech changes in certain types
Tiredness, breathing difficulty (especially at night) and heart rhythm or heart muscle problems in some types, usually later
Learning difficulties or delayed speech can occur in some children with Duchenne. Not every child with these signs has muscular dystrophy, but they should always be checked by a doctor.
Main Types of Muscular Dystrophy
The types differ in which muscles they affect first, when symptoms begin, how quickly they progress and how they are inherited.
Inheritance patterns for each type are explained in detail in our upcoming guides. Over the coming weeks, MDP will publish a detailed guide on each of these types on this blog.
How Is Muscular Dystrophy Diagnosed?
Diagnosis usually begins with a doctor, ideally a neurologist or paediatric neurologist, who takes a detailed history, asks about relatives with similar problems, and examines muscle strength, walking and reflexes. The following tests are commonly used:
CPK (creatine kinase) blood test: CPK is an enzyme that leaks from damaged muscle. It is often very high in Duchenne and Becker. A high result suggests a muscle problem but does not by itself confirm the type.
Genetic testing: A blood test that looks for the exact gene change. It confirms the diagnosis in many cases, identifies the type, and is essential for family planning and for treatments that depend on the specific mutation.
EMG and nerve conduction studies: Help to tell whether the weakness comes from the muscle or from the nerves.
Muscle biopsy: A small piece of muscle is examined under the microscope, usually when genetic tests are not available or do not give a clear answer.
Heart and lung checks: ECG, echocardiogram and breathing tests may be done to see whether these organs are involved.
Because several conditions can look similar, a confirmed diagnosis is important before starting any treatment.
Treatment and Care: What Is Available Today?
For most types of muscular dystrophy there is no complete cure at present. However, careful medical care can improve quality of life and, in some types, slow the progression. Care works best when several specialists work together, such as a neurologist, a heart specialist, a lung or sleep specialist, an orthopaedic doctor and a nutrition expert, with the family as an equal partner.
Corticosteroids: In Duchenne, steroid medicines are widely used to slow the loss of muscle strength. They must be prescribed and monitored by a specialist because of side effects.
Heart care: Regular heart checks and medicines when needed protect the heart in types where it can be affected.
Breathing care: Lung function and sleep breathing are monitored, and support is provided when needed.
Bone, spine and general health: Doctors watch for scoliosis, bone thinning, weight changes and infections.
Newer therapies: Genetic therapies such as exon-skipping drugs and gene therapy exist or are in trials for some types, mainly Duchenne. They are mutation-specific, mostly available in other countries, and very expensive. A specialist can tell whether a patient may qualify.
Genetic counselling: Helps families understand inheritance and the risk for other relatives and future children.
A word of caution: Please be careful of "miracle cures", special oils or injections sold for muscular dystrophy. They have no proven benefit, can be expensive, and can delay proper care. Always consult a qualified specialist.
Muscular Dystrophy in Pakistan
Reliable national figures on muscular dystrophy in Pakistan are limited, which itself shows how little attention the condition has received. Families often face the same obstacles: low awareness, delayed or missed diagnosis, difficulty reaching a neuromuscular specialist, limited access to genetic testing, and the high cost of tests and long-term care. Marriages between relatives are common in many communities, and this raises the chance of recessive types appearing in a family.
That is why Muscular Dystrophy Pakistan (MDP) focuses on awareness, early diagnosis, patient registration and advocacy. Registering patients helps us understand the real picture and speak for their needs.
When Should You See a Doctor?
Please consult a doctor soon if you notice any of the following in a child or family member:
Frequent falls, difficulty rising from the floor, or climbing stairs with great effort
Walking on toes, waddling walk, or large-looking calves
Not walking by 18 months, or much slower motor development than other children
Progressive weakness in the arms, legs, face or shoulders at any age
A relative already diagnosed with muscular dystrophy
Early diagnosis does not change the genes, but it opens the door to the right monitoring, avoids wrong treatments, and allows the whole family to make informed decisions.
Frequently Asked Questions
Is muscular dystrophy contagious?
No. It cannot spread from person to person. It is caused by changes in genes.
Can girls get muscular dystrophy?
Yes. Some types affect boys and girls equally. In X-linked types like Duchenne and Becker, girls are mostly carriers, and a few carriers can have mild symptoms. Carriers should talk to a genetic counsellor.
Is there a cure for muscular dystrophy?
There is no complete cure for most types yet. Treatments that slow progression and protect the heart and lungs exist, and research is active worldwide.
Can muscular dystrophy be prevented?
It cannot be prevented once the gene change is present, but genetic counselling, carrier testing and prenatal options can help families plan future pregnancies.
At what age does muscular dystrophy start?
It depends on the type. Congenital types show at birth, Duchenne usually in early childhood, and others like myotonic dystrophy or OPMD in adulthood.
Does everyone with muscular dystrophy need a wheelchair?
Not always. It depends on the type and how it progresses. Some people remain walking for life, while in others walking becomes difficult over time. A specialist can guide each family.
Where can I get help in Pakistan?
Start with a paediatric neurologist or neurologist and ask about CPK and genetic testing. You can also follow this blog and MDP's official pages for guidance and patient registration updates.
