Specialty Definition: Muscular dystrophy

(From Wikipedia, the free Encyclopedia)

The muscular dystrophies are a group of genetic and hereditary myopathies that are characterized by progressive skeletal or voluntary muscle weakness and loss of muscle tissue and caused by defects in structural muscle proteins. The muscles of the heart and some other involuntary muscles are also affected in some forms of muscular dystrophy, and a few forms involve other organs as well.

Varieties and symptoms of muscular dystrophy

The major forms of muscular dystrophy include myotonic, Duchenne, Becker, limb-girdle, facioscapulohumeral, congenital, oculopharyngeal, distal, Emery-Dreifuss and severe childhood autosomal recessive muscular dystrophy. Duchenne is the most common form of muscular dystrophy affecting children, and myotonic muscular dystrophy is the most common form affecting adults. Muscular dystrophy can affect people of all ages. Although some forms first become apparent in infancy or childhood, others may not appear until middle age or later.

The most frequent symptoms are muscle weakness (frequent falls, walking problems, eyelid drooping), skeletal and muscle deformities. Neurologic examination often reveals loss of muscle tissue (wasting), muscle contracture, pseudohypertrophy and weakness. Diagnosis is usually established by muscle biopsy, elevated serum CK levels and electromyography examination, which is consistent with myogenic involvement. Some types of muscular dystrophy may present with additional cardiac disease, intellectual deterioration and infertility. There is no known cure for muscular dystrophy. Inactivity (such as bedrest and even sitting for long periods) can worsen the disease. Physical therapy and orthopedic instruments (e.g. wheelchairs) may be helpful.

Treatment

There is no specific treatment for any of the forms of muscular dystrophy. Physical therapy to prevent contractures (a condition in which shortened muscles around joints cause abnormal and sometimes painful positioning of the joints), orthoses (orthopedic appliances used for support) and corrective orthopedic surgery may be needed to improve the quality of life in some cases. The cardiac problems that occur with Emery-Dreifuss muscular dystrophy and myotonic muscular dystrophy may require a pacemaker. The myotonia (delayed relaxation of a muscle after a strong contraction) occurring in myotonic muscular dystrophy may be treated with medications such as phenytoin or quinine.

Prognosis

The prognosis of muscular dystrophy varies according to the type of muscular dystrophy and the progression of the disorder. Some cases may be mild and very slowly progressive, with normal lifespan, while other cases may have more marked progression of muscle weakness, functional disability and loss of ambulation. Life expectancy may depend on the degree of progression and late respiratory deficit. In Duchenne muscular dystrophy, death usually occurs in the late teens to early 20s.

Current research

The NINDS supports a broad program of research on muscular dystrophy. The goals of these studies are to increase understanding of muscular dystrophy and its cause(s), develop better therapies, and, ultimately, find ways to prevent and cure the disorder.
