In Duchenne Muscular Dystrophy, what is the average lifespan of affected individuals?

In Duchenne Muscular Dystrophy (DMD), the average lifespan for affected individuals is typically in the range of 20 to 30 years. This condition, which is a severe form of muscular dystrophy primarily affecting boys, leads to progressive muscle degeneration and weakness. The lack of dystrophin, a protein necessary for muscle function, contributes to the symptoms and the decreased life expectancy.

While advancements in supportive care and management strategies have resulted in improved quality of life and, for some, an extension of lifespan beyond the traditional range, the classic average remains around 20 to 30 years. It is essential to note that the variability in lifespan can depend on factors such as the severity of the disease, the timing of diagnosis, and the level of supportive therapies applied throughout the individual's life.
