What is myotonic dystrophy?
Myotonic dystrophy is an inherited type of muscular
dystrophy that affects the muscles and other body systems.
People who have myotonic dystrophy have muscle wasting and
weakness in their lower legs, hands, neck and face that get
worse over time. Signs and symptoms of myotonic dystrophy
usually develop when a person is in his or her twenties or
thirties. The severity of myotonic dystrophy varies widely
among those who have it, even among family members.
The weakness and muscle wasting that occurs slowly progress
to the point of disability. Usually, disability does not become
severe until fifteen to twenty years after the symptoms appear.
The progression of muscle weakness is slower and is less
serious in people who are older when the muscle weakness is
first noticed.
