Myotonic dystrophy is a form of muscular dystrophy. It is a chronic genetic disorder that manifests itself primarily as muscle loss and weakness. It comes in 2 forms that are known as DM1 and DM2. DM1 is evident at birth while DM2 appears in adulthood and is generally milder.
Symptoms include increasing muscle loss and weakness. The muscles are frequently seen to contract and be unable to relax. Additionally, the patient may experience cataracts, intellectual disability, and heart problems. In male patients, they may experience early balding and sterility. Genetic analysis is required for a definitive diagnosis.
