What is the most common form of muscular dystrophy?

Duchenne's muscular dystrophy (DMD) is indeed the most common form of muscular dystrophy, primarily affecting young boys. It results from a mutation in the dystrophin gene, leading to a lack of dystrophin protein, which is crucial for maintaining muscle cell integrity. Without this protein, muscle fibers become damaged and progressively degenerate, leading to severe muscle weakness and wasting.

DMD typically manifests between the ages of 2 and 5, with symptoms including difficulty walking, frequent falls, and challenges with motor skills. As the condition progresses, there may be loss of ambulation, respiratory complications, and heart issues, making early diagnosis and management essential.

While other forms of muscular dystrophy like Becker's, Limb-girdle, and Facioscapulohumeral muscular dystrophies also present significant concerns, they are less prevalent and often exhibit milder symptoms or later onset compared to Duchenne's muscular dystrophy. The prominence of DMD in the population and its characteristic early onset make it the most recognized and significant type in pediatric care.
