Muscular Dystrophy (MD) and Related Diseases

Muscular Dystrophy (MD) and Related Diseases

The muscular dystrophies (MD) are a group of more than 30 genetic diseases characterized by progressive weakness and degeneration of the skeletal muscles that control movement. Some forms of MD are seen in infancy or childhood, while others may not appear until middle age or later. MD is a progressive disease and symptoms may get worse over time.

Becker MD starts with muscle loss and weakness in the pelvis, things and shoulders. It is often described as a milder form of Duchenne MD.

Duchenne MD is the most common form of MD and primarily affects boys. Onset is between 3 and 5 years and the disorder progresses rapidly.

Myotonic MD is the disorder’s most common adult form and individuals display prolonged muscle spasms, cataracts, cardiac abnormalities, and endocrine disturbances. Individuals with myotonic MD have long, thin faces, drooping eyelids, and a swan-like neck
