How is muscular dystrophy diagnosed?

Diagnosis of muscular dystrophy involves a careful medical history and a thorough physical exam to determine the

distribution of symptoms and to rule out other causes. Family history may give important clues, since all the muscular dystrophies are genetic conditions (though no family history will be evident in the event of new mutations). Muscle-stimulation tests, known as electromyography or EMG, use electrical shocks to cause muscle movement. This movement is abnormal in muscular dystrophy. A doctor usually takes a muscle biopsy - in which a small piece of the muscle is removed for examination under a microscope - to be sure of the diagnosis. Under the microscope, the muscle generally shows dead tissue and abnormally large muscle fibers. In the late stages of muscular dystrophy, fat and other tissues replace the dead muscle tissue. In the past, certain blood tests that are used to analyze DNA allowed some forms of muscular dystrophy to be diagnosed by identifying a particular mutation of the dystrophin gene. A new DNA test, called single condition amplification/internal primer (SCAIP) sequencing, allows doctors to look at the entire dystrophin gene to find multiple variations, providing more than just one type of diagnosis. Researchers are hoping that this test will soon become more widely available to the public.

More information on muscular dystrophy

What is muscular dystrophy? - Muscular dystrophy is a group of inherited diseases that are characterized by weakness and wasting away of muscle tissue.
What types of muscular dystrophy are there? - There are nine types of muscular dystrophy including Duchenne muscular dystrophy, Becker muscular dystrophy, facioscapulohumeral muscular dystrophy.
What causes Duchenne muscular dystrophy (DMD)? - Duchenne muscular dystrophy is a rapidly progressive form of muscular dystrophy. It is caused by a defective gene.
What're the symptoms of Duchenne muscular dystrophy? - Symptoms of Duchenne muscular dystrophy include progressive muscle weakness of the legs and pelvis, mental impairment or heart problems.
What causes Becker's muscular dystrophy? - Becker muscular dystrophy is a type of dystrophinopathy which include a spectrum of muscle disease caused by mutations in the DMD gene.
What're the symptoms of Becker's muscular dystrophy? - Symptoms of Becker-type muscular dystrophy are similar to those of Duchenne dystrophy, but they are milder and begin later.
What causes limb-girdle muscular dystrophy? - Limb-girdle muscular dystrophy is an inherited disorder, it may be inherited as a dominant, recessive, or X-linked genetic defect.
What're the symptoms of limb-girdle muscular dystrophy? - Symptoms of limb-girdle muscular dystrophy include progressive muscle weakness in the shoulders and hips, together with breathing problems.
What causes facioscapulohumeral muscular dystrophy? - Facioscapulohumeral muscular dystrophy involves progressive muscle weakness and loss of muscle tissue.
What're the symptoms of facioscapulohumeral muscular dystrophy? - Symptoms of facioscapulohumeral muscular dystrophy may begin during infancy, late childhood, or early adulthood.
What causes myotonic dystrophy? - Myotonic dystrophy is caused by an inherited gene defect. Myotonic dystrophy is the most common form of adult muscular dystrophy.
What're the symptoms of myotonic dystrophy? - Symptoms of myotonic dystrophy include muscle weakness and wasting, cataracts, heart problems, constipation and other digestive problems.
How is muscular dystrophy diagnosed? - Diagnosis of muscular dystrophy involves a medical history and physical exam to determine the distribution of symptoms and to rule out other causes.
What's the treatment for muscular dystrophy? - Treatments for muscular include decreased mobility and dexterity, contractures, scoliosis, heart defects, and respiratory weaknesses.
