Early Recognition and Understanding of Muscular Dystrophy
Muscular dystrophy (MD) is a group of inherited disorders that lead to progressive muscle weakness and a reduction in muscle mass. Over time, these changes can interfere with movement, independence, and daily activities. Although there is no cure, recognizing symptoms early and receiving an accurate diagnosis allows for better management and improved quality of life.
At Neurocare of Nevada, we aim to raise awareness of the signs that may indicate different forms of muscular dystrophy. This article outlines common symptoms to watch for and encourages timely medical evaluation. In the United States, the diagnostic process often includes a neurological examination combined with genetic testing to confirm the condition. Understanding these indicators is an essential first step in accessing the proper care and support.
General Signs of Muscle Weakness and Developmental Delays
The first signs of muscular dystrophy can appear at different ages. Attention to early changes in strength and movement helps guide timely medical evaluation.
Developmental Red Flags in Children
Children with muscular dystrophy may delay reaching motor milestones, such as sitting, crawling, or walking. Parents may also notice frequent falls, clumsiness, or difficulty keeping up with peers during play.
A well-known indicator of Duchenne muscular dystrophy is Gower’s sign, where a child uses their hands to push against their legs to stand due to weakness in the hips and thighs. Other early signs include a waddling gait, toe-walking, or enlarged calves (pseudohypertrophy).
Despite appearing large, these muscles are weak because normal muscle tissue is replaced by fat and connective tissue. Persistent difficulty climbing stairs or standing from the floor also points to hip and thigh weakness. Parents noticing these changes should consult a pediatrician for further evaluation.
Emerging Weakness in Adolescents and Adults
In teens and adults, symptoms often appear as gradual muscle weakness. The affected muscle groups vary depending on the type of MD but may involve the hips, shoulders, face, or hands. Everyday tasks such as climbing stairs, rising from a chair, lifting overhead, buttoning clothes, or turning doorknobs may become harder. Fatigue, stiffness, or muscle cramps can also develop due to weakness or joint contractures.
Type-Specific Symptoms
Different forms of muscular dystrophy present with distinct patterns of weakness and progression.
Duchenne Muscular Dystrophy (DMD)
DMD is the most common and severe form in children, usually appearing before age 5. It progresses quickly, with early signs such as Gower’s sign, waddling gait, and calf enlargement. As the condition advances, weakness spreads to the arms, trunk, and legs. DMD can also affect the heart (cardiomyopathy), breathing muscles, and the spine (scoliosis). Some children may also have learning or behavioral challenges.
Becker Muscular Dystrophy (BMD)
BMD is related to DMD but develops later, usually in the teen years or young adulthood, and progresses more slowly. Many people remain able to walk into adulthood. However, heart involvement is a significant concern, requiring ongoing monitoring.
Myotonic Muscular Dystrophy (DM)
DM is the most common adult-onset type. Its hallmark feature is myotonia, where muscles have difficulty relaxing after contraction, such as being unable to release a handshake. It often affects muscles of the hands, feet, face, and lower legs. Other issues include drooping eyelids, cataracts, swallowing difficulties, and heart rhythm disturbances.
Limb-Girdle Muscular Dystrophy (LGMD)
LGMD primarily affects the muscles around the hips and shoulders, leading to a waddling walk and difficulty standing from a chair or climbing stairs. Onset and progression vary widely depending on the genetic subtype.
Facioscapulohumeral Muscular Dystrophy (FSHD)
FSHD often begins in adolescence or adulthood and commonly affects one side of the body more than the other. Symptoms include facial weakness (such as difficulty closing the eyes fully or smiling), as well as shoulder weakness that causes the shoulder blades to stick out (winged scapulae) and makes lifting the arms overhead difficult.
When to Seek Medical Attention
Knowing when to move from observation to medical evaluation is essential.
- Progressive weakness: Any unexplained or worsening muscle weakness should be assessed by a physician.
- Developmental delays: Children not meeting expected motor milestones should be evaluated promptly.
- Systemic symptoms: Breathing problems, heart palpitations, or swallowing difficulties require urgent medical review.
- Family history: Inform your doctor of any family history of muscular dystrophy or unexplained muscle weakness, which helps guide the diagnostic process.
In the United States, evaluation usually begins with a primary doctor or pediatrician, followed by referral to a neurologist. Diagnosis may involve blood tests for creatine kinase (CK), genetic testing, and sometimes, a muscle biopsy. Support from organizations like the Muscular Dystrophy Association (MDA) is also available.
Diagnosis and Management in the United States
Receiving a diagnosis is the starting point for ongoing management.
- Diagnostic process: It begins with a clinical exam, followed by laboratory tests such as CK levels and genetic testing. Muscle biopsy is less common today.
- Management approach: Care typically involves a team led by a neurologist, with input from therapy, cardiac, and respiratory professionals as needed.
- Treatment goals: Although no cure exists, treatment focuses on slowing progression, preventing complications, and maintaining function. This may involve medications, physical therapy, assistive devices, and close heart and lung health monitoring.
At Neurocare of Nevada, Dr. Chopra and the team evaluate, diagnose, and provide access to current treatment options for patients with muscular dystrophy.
Committed to Neurological Health
Muscular dystrophy is a lifelong condition, but early recognition of symptoms allows for better management and quality of life. Persistent weakness, developmental delays, or systemic symptoms should never be ignored. Consulting a doctor promptly can lead to referral for focused care.

Frequently Asked Questions
Q: Can muscular dystrophy occur without a family history?
Yes. While often inherited, MD can also result from new genetic mutations (de novo mutations).
Q: How do Duchenne and Becker muscular dystrophy differ?
Both involve mutations in the dystrophin gene. Duchenne causes little to no functional protein and progresses quickly in childhood. Becker allows for some functional protein, so symptoms appear later and progress more slowly.
Q: Are treatments available in the United States?
Yes. While there is no cure, therapies aim to slow progression and manage symptoms. Corticosteroids, gene-targeted therapies, physical therapy, assistive devices, and heart and lung health monitoring are common approaches.
Q: Can diet and exercise help?
A balanced diet supports overall health. A therapist should guide physical activity to maintain flexibility and prevent joint tightening. Strenuous or high-impact exercise is usually avoided.
Q: What resources are available?
The Muscular Dystrophy Association (MDA) provides education, support services, and connections to clinics nationwide.
