By age 10, which three symptoms are typically seen?

• A. Falling; Fatigue; Ambulation only household distances
• B. Headache; Dizziness; Nausea
• C. Increased appetite; Weight gain; Improved gait
• D. Speech difficulties; Hearing loss; Memory issues

Answer: (A)

In Duchenne muscular dystrophy, school-age progression shows progressive proximal muscle weakness that hits the legs hardest. That weakness leads to easy fatigue with activity and a higher risk of falls. As the condition advances, independent walking becomes limited to short distances at home because outdoor ambulation is no longer feasible. So the trio of falling, increased fatigue with activity, and ambulating only within household distances fits the expected pattern for a 10-year-old with this diagnosis and guides rehab toward safety, energy conservation, and planning assistive mobility.

The other symptom sets describe issues that aren’t the typical progression for this age and condition—for example, headaches with dizziness and nausea, or weight gain with an improved gait, or sensory/cognitive concerns—that don’t reflect the core decline in mobility seen in this context.
