What Is Muscular Dystrophy?
7. Distal
Adult men and women are affected by this rare type of MD. With onset from ages 40 to 60, the progress of this disease is slow, rarely incapacitating its victims. The distal muscles in the lower arms and legs are impacted by gradual weakening and eventual atrophy.
In time, other muscle groups may also be affected. Visible loss of muscle mass, marked by a decrease in size, can easily be seen. Range of motion and mobility may be limited. Other less common forms of Distal can affect the heart or the muscles used for speaking and swallowing.
