1 Duchenne. 2  The most common form of muscular dystrophy in children, Duchenne muscular dystrophy affects only males. 3  It appears between the ages of 2 and 6. 4  The muscles decrease in size and grow weaker over time yet may appear larger.
Muscular dystrophies are a group of genetic conditions characterized by progressive muscle weakness and wasting (atrophy). The Duchenne and Becker types of muscular dystrophy are two related conditions that primarily affect skeletal muscles, which are used for movement, and heart (cardiac) muscle.These forms of muscular dystrophy occur almost exclusively in males.oth the Duchenne and Becker forms of muscular dystrophy are associated with a heart condition called cardiomyopathy. This form of heart disease weakens the cardiac muscle, preventing the heart from pumping blood efficiently. In both Duchenne and Becker muscular dystrophy, cardiomyopathy typically begins in adolescence.
