Myotonic dystrophy (dystrophia myotonica, myotonia atrophica) is a chronic, slowly progressing, highly variable, inherited multisystemic disease. It is characterized by wasting of the muscles (muscular dystrophy), cataracts, heart conduction defects, endocrine changes, and myotonia. Two types of myotonic dystrophy exist. Myotonic dystrophy type 1 ...

Myotonic dystrophy: An inherited disease in which the muscles contract but have decreasing power to relax -- this phenomenon is termed myotonia (irritability and prolonged contraction of muscles). The disease also leads to a mask-like expressionless face, premature balding, cataracts, and heart arrhythmias (abnormalities in heart rhythm). The onset...
