Is muscular dystrophy non progressive?
Muscular dystrophy is a group of diseases that cause progressive weakness and loss of muscle mass. In muscular dystrophy, abnormal genes (mutations) interfere with the production of proteins needed to form healthy muscle.
Is myotonia congenita a form of muscular dystrophy?
Myotonia congenita is a congenital neuromuscular channelopathy that affects skeletal muscles (muscles used for movement). It is a genetic disorder….
| Myotonia congenita | |
|---|---|
| Causes | Genetic, CLCN1 mutations |
| Diagnostic method | Clinical, genetic testing |
| Differential diagnosis | Myotonic dystrophy, Paramyotonia congenita |
What are the two types of myotonia congenita?
Two main forms of myotonia congenita have been described: Thomsen disease and Becker disease.
Are people born with myotonia?
Mild myotonic dystrophy is apparent in mid to late adulthood. Affected individuals typically have mild myotonia and cataracts. Congenital myotonic dystrophy is often apparent at birth.
What type of muscular dystrophy has the most rapid progression?
Duchenne muscular dystrophy is the most common type of muscular dystrophy diagnosed in childhood. It first appears in very early childhood—only in boys—and progresses rapidly. Most children are unable to walk by age 12 and later need a respirator to breathe.
Is there such a thing as a non dystrophic myotonia?
Non-dystrophic myotonias (NDMs) are skeletal muscle disorders involving myotonia distinct from myotonic dystrophy. It has been reported that the muscle pathology is usually normal or comprises mild myopathic changes in NDMs.
What kind of muscle problems does myotonia congenita cause?
Myotonia congenita is an inherited myopathy, a disease that causes problems with the tone and contraction of skeletal muscles. It doesn’t cause muscle atrophy (shrinkage); instead, it sometimes can cause muscle enlargement and increased muscle strength. There are two types of myotonia congenita: Becker-type myotonia is…
Is there a difference between myotonia congenita and Thomsen disease?
It doesn’t cause muscle atrophy (shrinkage); instead, it sometimes can cause muscle enlargement and increased muscle strength. There are two types of myotonia congenita: Becker-type myotonia is the most common form, while Thomsen disease is a very rare, relatively mild form.
How is myotonia congenita related to Becker Type?

What kind of muscle weakness does myotonic dystrophy cause?
This disease is characterized by progressive muscle loss and weakness. Myotonic dystrophy may be further classified into two types, and the two types may affect different muscles. People with myotonic dystrophy usually have prolonged muscle tensing ( myotonia) and are not able to relax certain muscles after use.
