Which condition typically manifests symptoms before the age of 6?

• A. Huntington's Disease
• B. Sickle Cell Anemia
• C. Duchenne Muscular Dystrophy
• D. Cystic Fibrosis

Answer: (C)

Duchenne Muscular Dystrophy is a genetic disorder that specifically impacts young boys and typically shows symptoms before the age of 6. Children with this condition often experience delayed motor milestones, such as difficulty running or climbing stairs, frequent falls, and muscle weakness. The onset of these symptoms can lead to a progressive decline in muscle function, which is a hallmark characteristic of this particular disorder. In contrast, Huntington's Disease is a neurodegenerative disorder that generally appears in mid-adulthood, and is characterized by a gradual decline in mental and physical functions. Sickle Cell Anemia, while it can present symptoms early in life, often has its most serious manifestations appearing later and is related to episodic pain crises and anemia rather than the immediate motor deficiencies characteristic of muscular dystrophy. Cystic Fibrosis typically presents with respiratory and digestive issues in infancy or early childhood, but does not specifically correlate with the same motor development delays seen in Duchenne Muscular Dystrophy. Therefore, the emphasis on motor skill deterioration and the age at which symptoms generally appear makes Duchenne Muscular Dystrophy the correct answer, as it is a condition that distinctly shows signs before the age of 6.
