What is a primary characteristic of Muscular Dystrophy?

1. Delayed motor skills development

2. Degenerative disability that may lead to early death

3. Difficulty in social interactions

4. Overactivity and impulsivity

The correct answer is: Degenerative disability that may lead to early death

A primary characteristic of Muscular Dystrophy (MD) is that it is a degenerative disability that may lead to early death. This condition encompasses a group of inherited disorders characterized by progressive weakness and degeneration of the skeletal muscles, which are responsible for movement. Over time, the muscles weaken due to the absence of a protein called dystrophin that is essential for maintaining muscle integrity. As the disease progresses, many individuals may experience significant physical limitations and complications affecting respiratory and cardiac functions, which can ultimately lead to reduced life expectancy. Understanding this aspect is crucial for educators and professionals in special education, as it underscores the importance of providing appropriate support and intervention strategies to help manage the physical challenges associated with MD. In contrast, while delayed motor skills development may occur due to muscular weakness, it is not the defining characteristic of the condition. Difficulty in social interactions and overactivity/impulsivity are more associated with different developmental or behavioral disorders rather than Muscular Dystrophy itself.
