Muscular Dystrophy Guide: Early Signs Every Parent Needs

Watching children grow and hit new milestones is a cherished time for parents, yet it can be concerning when a child’s development seems delayed. This delay may also turn into a muscular dystrophy, or MD, diagnosis, where children show delayed motor skills or muscle weakness. Detecting the early signs of MD is not always easy, but it’s important to seek medical treatment should you suspect issues with your child’s development.

Understanding Muscular Dystrophy in Children

The possibility of a muscular dystrophy diagnosis, especially in a child, can be daunting. This is why it’s crucial to understand the condition and its warning signs.

What Is Muscular Dystrophy?

Muscular dystrophy (MD) is not a single disorder but a group of inherited genetic conditions that cause progressive weakening and loss of muscle strength. In children with MD, the muscles gradually lose their ability to function correctly over time, not because of an injury or infection, but due to genetics. A child’s muscular dystrophy type determines which muscles are most affected, how quickly the condition progresses, and the severity of symptoms.

Genetic Basis of Muscular Dystrophy

The underlying cause of MD is almost always a genetic mutation, which can be inherited from one or both parents. A parent may be an asymptomatic gene carrier, or the condition may derive from a new mutation. Either way, MD is caused by the genes responsible for building and maintaining healthy muscle function, whether the gene runs in the family or not.

Common Types of Muscular Dystrophy

There are several types of muscular dystrophy, some seen more commonly in children than others, and each has its own unique characteristics.

Duchenne Muscular Dystrophy (DMD)

DMD is not only the most common form of muscular dystrophy in children, but also the most severe. This type of MD is most prevalent in boys, becoming most apparent in early childhood. Signs include difficulty running, climbing stairs, and frequently falling. DMD progresses rapidly and often leads to the inability to walk and can advance to the heart and respiratory muscles.

Becker Muscular Dystrophy (BMD)

BMD is closely related to Duchenne, but is often less severe and progresses more slowly. This type of MD is also predominant in boys, but unlike DMD, it tends to appear later in childhood, and children affected by it often maintain the ability to walk. The progression of BMD can vary significantly from child to child.

Myotonic Dystrophy

Myotonic dystrophy emphasizes the disease’s genetic disposition, as it tends to run in families. With myotonic dystrophy, the muscles have trouble relaxing once contracted. Children with this condition may have muscle weakness, learning difficulties, or developmental delays.

Limb-Girdle Muscular Dystrophy (LGMD)

LGMD, which is seen in both boys and girls, is a group of conditions that affect the hip, thigh, upper arm, and shoulder muscles. This condition may start in childhood with signs such as weakness in the hips or shoulders that make climbing stairs or walking long distances difficult.

Early Motor Skill Delays as Key Indicators

A parent’s keen eye may notice the subtle changes in their child’s development, especially their child’s motor skills. Motor skill delays may be key indicators and early signs of muscular dystrophy.

Signs of Delayed Walking

Most children walk independently between 12 and 15 months of age. Parents may want to consider reaching out to a professional if their child is a late walker, a child who starts walking at 18 months or later, or has a noticeable gait. Although some children are late bloomers, delayed walking can be an early indicator of MD.

Signs of Muscle Weakness in Children

Children are often energetic and become more active as they grow. If your child struggles to keep up with their peers during playtime, tires quickly, stumbles often, or begins avoiding running or jumping, it may indicate something other than a lack of interest. Avoiding physical activity may be an early sign of muscle weakness, making physical activities more difficult.

Other signs of muscle weakness may include your child needing extra assistance getting up after sitting down, having trouble balancing when standing after sitting, and heavily relying on stair handrails for support rather than holding them for safety.

Here’s a quick checklist of motor skill indicators to discuss with your pediatrician:

Recognizing Other Physical Signs

Although delayed walking and muscle weakness may be prominent MD symptoms, children may exhibit other physical signs leading to a diagnosis.

Frequent Falls and Tripping

We all stumbled when learning to walk, but repeated stumbling, clumsiness, or trouble regaining balance after a fall may be cause for concern. For example, if playtime isn’t rowdy and your child is struggling with simple movements or walking on level ground, it may be best to speak with a medical professional.

Distinctive Walking Patterns

Observe your child’s gait. Watch if they develop a “waddling” gait, where they sway from side to side due to weakness in the hip and thigh muscles. Another indicator can be walking on their toes or the balls of their feet, which might be a compensatory mechanism for weak ankle muscles. Any persistent or unusual walking patterns warrant attention.

Enlarged Calf Muscles (Pseudohypertrophy)

Paradoxically, in some types of muscular dystrophy (especially Duchenne), the calf muscles might look larger than usual. This is called pseudohypertrophy, where fat and connective tissue replace the degenerating muscle tissue. This creates larger calves that lack the strength of their appearance.

Gower’s Sign: A Unique Movement

Gower’s Sign is a distinct movement that children with weak hip and thigh muscles use to stand up from the floor. Instead of simply pushing up, they roll onto their stomach, get onto their hands and knees, push their hips into the air, and then “walk” their hands up their legs to achieve an upright position. If you regularly observe your child using this method, it’s a strong indicator of proximal muscle weakness and requires immediate medical attention.

Subtle Signs of Muscle Weakness

At times, the signs of muscle difficulties can be subtler than delays in major motor milestones, making them easy to miss in young children.

Shoulder and Arm Weakness

You might notice your child having difficulty with tasks that require upper-body strength, such as lifting objects (even light ones), throwing a ball, or reaching for items on a high shelf. Simple everyday activities requiring arm and shoulder strength may become noticeably challenging.

Facial Muscle Weakness

Weakness in facial muscles can also manifest as difficulty making full facial expressions, such as a complete smile or tightly closing one’s eyes. Challenges with chewing or swallowing, or subtle changes in speech pattern, can also be signs.

Difficulty With Fine Motor Skills

Fine motor skills rely on the coordination of the small muscles in the hands and fingers. If your child consistently struggles with everyday tasks such as buttoning clothes, using utensils, writing or drawing, or handling small toys like building blocks, it may indicate underlying muscle weakness.

Related Developmental and Health Concerns

Muscular dystrophy may be known to affect muscle strength, but it’s also linked to other areas of a child’s development and health.

Learning and Academic Challenges

Some children with muscular dystrophy may face learning difficulties, such as difficulty concentrating and processing information. A teacher can monitor your child’s academic progress and offer advice for educational support to improve their learning experience at school.

Heart Health Considerations

Since the heart is a muscle, muscular dystrophy can also affect it through irregular heart rhythms or inefficient pumping. In this instance, visiting a cardiologist for tests like EKGs or echocardiograms to track heart function is essential.

Spinal Curvature and Posture (Scoliosis)

Progressive muscle weakness can also impact the spine, often leading to scoliosis (a sideways curvature of the spine) or other postural issues. This can cause discomfort and, if severe, affect breathing capacity. Physical therapy and bracing can help manage spinal curvature, and in some cases, surgical intervention may be necessary to correct the alignment and improve overall health and comfort.

When to Seek Medical Advice

It’s natural for parents to worry, but knowing when to seek professional medical advice is imperative for a child’s well-being.

Identifying Ongoing Symptoms

If your child shows a consistent pattern of motor delays, physical challenges that aren’t improving, or even a decline in previously acquired skills, it may signal something more significant. When everyday tasks that peers handle with ease remain a struggle or multiple signs of muscle weakness are present, it may be time to seek a professional evaluation.

Why Early Neurological Consultation Matters

Early detection plays a critical role in managing muscular dystrophy. Although there is currently no cure, receiving a diagnosis as soon as possible allows for:

Never hesitate to contact a healthcare professional if you have concerns. Trust your instincts as a parent; you know your child best, and it’s always better to be proactive in seeking answers.

Diagnostic Approaches for Muscular Dystrophy at Neurocare of Nevada

Knowing what to expect during the diagnostic process can help prepare parents for their child’s healthcare journey. Diagnostic approaches for MD may include a comprehensive physical exam, blood tests, and genetic testing.

Comprehensive Physical Examination

The process typically begins with a detailed physical exam. This may include evaluating muscle strength, reflexes, and coordination, as well as reviewing your child’s medical history and the symptoms you’ve noticed. The findings from this exam help determine whether additional tests are needed.

Enzyme Blood Tests (Creatine Kinase – CK)

Blood tests are often one of the first steps. Measuring creatine kinase (CK) levels can provide valuable insight, as elevated CK usually signals muscle damage, a common feature of muscular dystrophy. While CK results alone cannot confirm a diagnosis, they are an essential indicator that further evaluation is necessary.

Genetic Testing for Confirmation

Genetic testing is considered the most definitive way to confirm a muscular dystrophy diagnosis. By analyzing a blood sample, gene mutations linked to different types of the condition can be identified. This highly accurate testing helps to determine the exact type of muscular dystrophy.

Frequently Asked Questions (FAQs)

What exactly is muscular dystrophy?

Muscular dystrophy is a group of genetic diseases that cause progressive muscle weakness and breakdown over time. It occurs due to gene mutations responsible for producing proteins essential for healthy muscle function.

Is muscular dystrophy something that runs in families?

Yes, muscular dystrophy is a genetic condition, meaning it is often inherited. While it can be passed down through families, a new mutation can sometimes occur spontaneously in a child without a family history.

When do symptoms of muscular dystrophy usually start appearing?

The onset of muscular dystrophy symptoms in children varies by type. While some forms might show signs very early, even at birth, parents commonly begin noticing problems when their child is around 2 or 3. The average age for a formal diagnosis is about 5 years old.

What are the first things I should look out for in my child?

Parents should watch for early signs of muscular dystrophy (MD), such as persistent motor skill delays. MD symptoms like difficulty walking (especially after 15-18 months), struggling with running or jumping, frequent falls, challenges with stairs or standing up from the floor (e.g., Gower’s Sign), or subtle weakness in arms, shoulders, or facial muscles.

How do doctors diagnose muscular dystrophy in children?

Doctors diagnose muscular dystrophy in children through a physical examination, enzyme blood tests (like creatine kinase), and often definitive genetic testing. Neurodiagnostic procedures such as EMG and NCV are also frequently used.

Can muscular dystrophy be cured?

Currently, there isn’t a cure for muscular dystrophy. However, many effective ways exist to help manage the condition and improve a child’s quality of life. These include physical therapy, medications, and other treatments guided by a neurologist to control symptoms and complications.
