Common Physical Symptoms of Muscular Dystrophy in Adults

Adult-onset muscular dystrophy typically presents with gradual muscle weakness that affects specific muscle groups depending on the type of dystrophy. One of the most recognizable symptoms is proximal muscle weakness, affecting the muscles closest to the center of the body. This often manifests as difficulty climbing stairs, rising from a seated position, or lifting objects above the head.

Many adults also experience muscle wasting (atrophy), where muscles become visibly smaller over time. This symptom may be asymmetrical, affecting one side more than the other. Accompanying these changes, patients frequently report muscle pain and cramping, particularly after physical activity. The progression rate varies significantly between different types of muscular dystrophy, with some forms advancing slowly over decades while others progress more rapidly.

Mobility and Balance Challenges

As muscular dystrophy progresses in adults, changes in gait and balance become increasingly apparent. Many individuals develop a waddling gait or a tendency to walk on their toes due to weakening of hip and leg muscles. This altered walking pattern often leads to frequent falls and mobility limitations.

Balance problems stem from core muscle weakness and can significantly impact daily functioning. Adults with muscular dystrophy may find themselves relying on furniture for support when moving around their homes. Some forms of the condition cause contractures – permanent shortening of muscles or tendons that limit range of motion and contribute to mobility difficulties. These physical changes typically develop gradually, allowing many adults to adapt their movements and environments to accommodate their changing abilities.

Respiratory and Cardiac Complications

Muscular dystrophy can affect the muscles involved in breathing, leading to significant respiratory complications in adults. Warning signs include shortness of breath, particularly when lying flat, morning headaches from carbon dioxide retention during sleep, and frequent respiratory infections due to weakened coughing ability. The Muscular Dystrophy Association recommends regular pulmonary function testing to monitor breathing capacity.

Cardiac involvement is another serious aspect of many muscular dystrophy types. Adults may develop cardiomyopathy (heart muscle disease) or cardiac conduction abnormalities. Symptoms can include irregular heartbeat, dizziness, fatigue, and in some cases, heart failure. The American Heart Association suggests that adults with muscular dystrophy undergo regular cardiac evaluations, as heart complications can occur even when skeletal muscle symptoms are mild.

Non-Muscular Symptoms and Systemic Effects

Beyond muscle-related issues, adults with muscular dystrophy often experience a range of systemic symptoms. Digestive problems may include dysphagia (difficulty swallowing), gastroesophageal reflux, and constipation due to weakening of the muscles involved in digestion. These symptoms can impact nutrition and overall health.

Cognitive and psychological effects vary widely depending on the type of muscular dystrophy. Some forms, like myotonic dystrophy, may include cognitive impairment or executive function difficulties. Many adults with progressive muscle conditions also experience depression or anxiety related to their changing abilities. The Centers for Disease Control and Prevention highlights the importance of addressing both the physical and psychological aspects of chronic conditions like muscular dystrophy.

Diagnostic Approaches and Treatment Options

When adults present with muscular dystrophy symptoms, healthcare providers typically begin with a thorough clinical examination and family history. Diagnostic testing often includes blood tests for creatine kinase (an enzyme that leaks from damaged muscles), genetic testing, electromyography (EMG), and muscle biopsy. The National Institute of Neurological Disorders and Stroke provides comprehensive information about these diagnostic procedures.

While there is no cure for muscular dystrophy, treatment approaches focus on managing symptoms and maintaining function. Physical therapy helps maintain muscle strength and flexibility, while occupational therapy provides strategies for daily living activities. Assistive devices such as braces, walkers, or wheelchairs may improve mobility. For some types of muscular dystrophy, medications like corticosteroids can help preserve muscle function. The Muscular Dystrophy UK offers resources on current treatment approaches and clinical trials investigating new therapies aimed at slowing disease progression or addressing specific genetic causes.

Conclusion

Recognizing muscular dystrophy symptoms in adulthood is crucial for early intervention and comprehensive care. If you notice progressive muscle weakness, mobility changes, or respiratory difficulties, consult a neurologist specializing in neuromuscular disorders. While muscular dystrophy remains a challenging condition, advances in supportive care, genetic research, and emerging therapies continue to improve outcomes and quality of life for adults living with these conditions. A multidisciplinary approach involving neurologists, cardiologists, pulmonologists, and rehabilitation specialists offers the best path forward for symptom management and maintaining independence as long as possible.
