Becker and Congenital Muscular Dystrophy
Becker MD is milder form of Duchenne MD. Only boys are affected, but with less severe symptoms. Life expectancy is similar to males without MD.
Congenital muscular dystrophy starts at birth. Both males and females can be affected. Beside progressive muscles weakening, a significant sign of this type of MD is muscle contractions that are present at birth. It is common for those with CMD to suffer from seizures, since this form of the disease affects the brain. Life expectancy is often decreased.
