What is a common symptom of Duchenne Muscular Dystrophy?

• A. Mental retardation
• B. Difficulty breathing
• C. Delayed puberty
• D. Uncontrolled movements

Answer: (A)

Duchenne Muscular Dystrophy (DMD) is known primarily for its impact on muscle function, and while there are associated complications that can affect cognitive function, mental retardation is not a direct symptom of DMD. One of the hallmark symptoms of DMD is difficulty breathing, which occurs as the muscles responsible for respiratory function weaken over time due to the progressive nature of the disease. Children with DMD often begin to show signs of muscle weakness around the ages of 2 to 6, which can eventually lead to respiratory complications as the condition advances. Other symptoms related to DMD can include delayed puberty due to the overall impact on muscle and body systems, but this is not as commonly recognized as difficulty breathing. Uncontrolled movements are not characteristic of DMD, which typically is associated with muscle weakness and atrophy instead. In summary, difficulty breathing stands out as a significant and common symptom directly tied to the muscular degeneration caused by Duchenne Muscular Dystrophy.
