summary/abstract:

Duchenne Muscular Dystrophy (DMD)is the most common of the muscular dystrophies affecting one in 3500 boys. Boys with DMD usually show symptoms of the disease by age three. The first symptoms may be a delay in achieving independent walking. A “waddling ” quality to the child’s walking and running is often noted. Difficulty in getting up from a seated position on the floor is commonly seen.

The disease is progressive, and boys lose the ability to walk by age 15 (many at a much younger age). Loss of respiratory (breathing) muscle power and involvement of heart muscle becomes life threatening in the late teens or early 20s.
