A group of genetic diseases which cause progressive skeletal muscle weakness, defects in muscle proteins, and the death of muscle cells and tissue
There are many types but two are most apt to be found in the college community In Aran-Duchene disease (adult progressive spinal muscular dystrophy), the muscles of the hands are impaired, there may be involuntary twitching of the hand and arm muscles, and the legs may be weak and stiff In myotonic dystrophy, there is stiffness in the limbs and a difficulty in relaxing the grip, the voice may have a nasal quality, and facial muscles are weakened, resulting in a mask-like appearance Both types of MD are progressive
the name given to a group of diseases that are, for the most part, genetically determined and cause gradual wasting of muscle with accompanying weakness and deformity
Progressive muscle weakness and atrophy caused by deficient dystrophin protein
Muscular dystrophy refers to any one of a group of muscle diseases in which there is a recognizable pattern of inheritance They are marked by weakness and wasting of selected muscles The affected muscle fibers degenerate and are replaced by fatty tissue The dystrophies are classified according to the patient's age at onset, distribution of the weakness, progression of the disease, and mode of inheritance The most common form is Duchenne dystrophy, which is inherited as a sex-linked recessive gene and is nearly always restricted to boys It usually begins before the age of four, with weakness and wasting of the muscles of the pelvis and back
any of several hereditary diseases of the muscular system characterized by weakness and wasting of skeletal muscles
Muscular dystrophy is a serious disease in which your muscles gradually weaken. a serious illness in which the muscles become weaker over a period of time. Inherited disease that causes progressive weakness in the skeletal (and occasionally heart) muscle. Muscle tissue degenerates and regenerates randomly and is replaced by scar tissue and fat. There is no specific treatment. Physical therapy, braces, and corrective surgery may help. Duchenne muscular dystrophy, the most common, strikes only males. Symptoms, including frequent falls and difficulty in standing up, start in boys 3-7 years old; muscle wasting progresses from the legs to the arms and then the diaphragm. Pulmonary infection or respiratory failure usually causes death before age
Any of a group of hereditary diseases characterized by progressive degeneration of the muscles
One of several conditions that affect the muscles and nerves, causing weakness and movement difficulties All are caused by a genetic defect, and in some cases the gene has been identified There is no cure for any form of MD yet, but experimental gene therapy is currently being investigated
This term is used to designate a group of muscle-destroying disorders which vary in hereditary pattern, age of onset, initial muscles attacked, and rate of progression These disorders include, but are not limited to
A group of genetic degenerative myopathies characterized by weakness and muscle atrophy without nervous system involvement The three main types are pseudohypertrophic (Duchenne, Becker), limb-girdle, and facioscapulohumeral
A group of diseases that gradually weakens muscle tissue; usually becomes evident by the age of four or five
a broad term that describes a genetic (inherited) disorder of the muscles MD causes the muscles in the body to become very weak The muscles break down and are replaced with fatty deposits over time The most common form of MD is called Duchenne's muscular dystrophy (DMD)

The gene can now be detected in female carriers and male fetuses. Becker dystrophy, also sex-linked, is less severe and begins later. Patients remain able to walk and usually survive into their 30s and 40s. Myotonic muscular dystrophy affects adults of both sexes, with myotonia and degeneration two to three years later, along with cataracts, baldness, and gonadal atrophy. Limb-girdle dystrophy affects the pelvic or shoulder muscles in both sexes. Facioscapulohumeral (face, shoulder-blade, and upper-arm) dystrophy starts in childhood or adolescence and affects both sexes; after initial symptoms of difficulty raising the arms, the legs and pelvic muscles can be affected; the main facial effect is difficulty in closing the eyes. Life expectancy is normal

becker muscular dystrophy
a form of muscular dystrophy that set in in adolescence or adulthood and progresses slowly but will affect all voluntary muscles; characterized by generalized weakness and muscle wasting that affects limb and trunk muscles first; similar to Duchenne's muscular dystrophy but less severe; inheritance is X-linked recessive (carried by females but affecting only males)
distal muscular dystrophy
a form of muscular dystrophy that sets in between 40 and 60 years of age and is characterized by weakness and wasting of the muscles of the hands and forearms and lower legs; inheritance is autosomal dominant
duchenne's muscular dystrophy
the most common form of muscular dystrophy; inheritance is X-linked recessive (carried by females but affecting only males)
limb-girdle muscular dystrophy
an autosomal recessive form of muscular dystrophy that appears anywhere from late childhood to middle age; characterized by progressive muscular weakness beginning either in the shoulder or pelvic girdle; usually progresses slowly with cardiopulmonary complications in the later stages
myotonic muscular dystrophy
a severe form of muscular dystrophy marked by generalized weakness and muscular wasting that affects the face and feet and hands and neck; difficult speech and difficulty with the hands that spreads to the arms and shoulders and legs and hips; the onset can be any time from birth to middle age and the progression is slow; inheritance is autosomal dominant
oculopharyngeal muscular dystrophy
a form of muscular dystrophy that usually begins between early adulthood and middle age and first affects muscles of the eyelid and throat; progresses slowly with swallowing problems common as the disease progresses; inheritance is autosomal dominant
