Introduction Muscular dystrophy (MD) is a group of genetic disorders that cause progressive muscle weakness and loss of muscle mass. Over time, this leads to difficulties in movement, breathing, and even heart function. The condition primarily results from genetic mutations that interfere with the production of proteins essential for healthy muscle function. While there is currently no cure, advancements in research and treatment options have provided hope for individuals living with MD. Understanding the condition is crucial for early diagnosis, better management, and support for affected individuals and their families. 2. What Is Muscular Dystrophy? Muscular dystrophy refers to a group of inherited disorders characterized by progressive muscle degeneration and weakness. It occurs due to mutations in genes responsible for muscle structure and function. People with MD experience a gradual loss of muscle strength, often leading to mobility challenges. Some forms of MD appear in childhood, while others develop later in life. The severity and progression vary depending on the type of muscular dystrophy a person has. 3. Types of Muscular Dystrophy There are several types of muscular dystrophy, each affecting different muscle groups and progressing at different rates. The most common types include: Duchenne Muscular Dystrophy (DMD) The most severe and common form in children, primarily affecting boys. Symptoms appear between ages 2-5, leading to difficulty walking and muscle loss. Most patients require a wheelchair by their early teens. Becker Muscular Dystrophy (BMD) A milder form of DMD, with symptoms developing later in childhood or adulthood. Muscle weakness progresses more slowly, allowing some patients to walk into adulthood. Myotonic Muscular Dystrophy Affects both males and females, usually appearing in adulthood. Causes muscle stiffness (myotonia) and weakness, along with possible heart and respiratory issues. Facioscapulohumeral Muscular Dystrophy (FSHD) Weakness begins in the face, shoulders, and upper arms. Symptoms often appear in teenage years or early adulthood. Limb-Girdle Muscular Dystrophy Affects the muscles of the hips and shoulders first. Can appear in childhood or adulthood, progressing at varying speeds. Congenital Muscular Dystrophy Present at birth or in early infancy. Leads to muscle weakness, joint stiffness, and sometimes brain abnormalities. 4. Causes and Risk Factors Muscular dystrophy is caused by mutations in genes responsible for muscle function. These mutations prevent the body from producing necessary proteins, leading to muscle degeneration. Inheritance Patterns X-linked inheritance: Duchenne and Becker MD are inherited through the X chromosome, affecting males more frequently. Autosomal dominant: A single mutated gene from one parent can cause the disease (e.g., myotonic dystrophy). Autosomal recessive: Both parents must carry the mutated gene for a child to inherit the condition (e.g., limb-girdle MD). Who Is at Risk? Family history of muscular dystrophy increases the risk. Males are more likely to develop severe forms like Duchenne MD. Some cases occur due to spontaneous mutations with no family history. 5. Signs and Symptoms of Muscular Dystrophy Symptoms of muscular dystrophy vary depending on the type but generally include: Early Signs in Children Delayed motor skills (walking, running, jumping) Frequent falls Difficulty climbing stairs Waddling gait Progression of Symptoms Muscle wasting and weakness Difficulty breathing and swallowing Loss of ability to walk (in severe cases) Heart problems in later stages Each type of muscular dystrophy affects specific muscle groups at different rates, leading to unique patterns of progression. 6. How Is Muscular Dystrophy Diagnosed? Medical Evaluation Doctors assess muscle strength, reflexes, and movement patterns. Genetic Testing Identifies mutations in specific genes linked to muscular dystrophy. Muscle Biopsy Examines muscle tissue for signs of dystrophy. Electromyography (EMG) Tests electrical activity in muscles to detect weakness. Blood Tests Measures creatine kinase (CK) levels, which are elevated in MD patients.
