Symptoms
Symptoms common to most forms of muscular dystrophy may include:
Initial symptoms:
- Progressive weakening of muscles—Usually, those muscles closest to the trunk become weak first. Then, muscles further away weaken as the disease advances.
- Enlargement of muscles as they weaken
- Clumsiness
- Frequent falling and difficulty getting up
Later symptoms:
- Severe muscle deterioration, usually leading to use of a wheelchair
- Distortion of the body
- Muscle contraction and stiffening (often severe)
- Difficulty breathing
Severe Muscle Contraction of the Hand
Symptoms specific to Duchenne and Becker dystrophy include:
- Abnormally curved spine
- Enlargement and weakening of the heart muscle
- Pneumonia and other respiratory infections
Symptoms specific to myotonic muscular dystrophy include:
- Difficulty in letting go after a handshake
- Muscle weakness that affects the central nervous system, heart, digestive tract, glands, or eyes
Symptoms usually become progressively worse. In many forms, life expectancy is shortened.
Diagnosis
The doctor will ask about your symptoms and medical history. She will also do a physical exam.
Tests may include:
- Muscle tissue biopsy —removal of a sample of muscle tissue for testing
- Blood enzyme tests—testing a blood sample to look for elevated enzyme levels
- Genetic testing-using blood samples
- Electromyogram (EMG) —measures electrical impulses coming from muscles
- Nerve conduction study (NCS) —measures electrical impulses in the nerves
