Myotonic dystrophy may affect the heart muscle. A person who has myotonic dystrophy may have difficulty swallowing. Cold foods may cause some individuals to choke. Affected individuals may be susceptible to respiratory problems such as infections and shortness of breath. Premature balding may occur in some males, while females may experience thinning of their hair.
Diagnosis is made by a physician based on family history and a physical examination.
There is no cure for myotonic dystrophy at the present time. Treatment is symptomatic. That is, problems associated with myotonic dystrophy are treated individually. For example, surgery is available for correction of cataracts. Medication may be prescribed to counter the effects of myotonia.
