Muscular Dystrophy
  • Muscular dystrophy is a cluster of diseases that
    cause gradual weakness and loss of muscle mass
    with time. In this condition, abnormal genes
    (mutations) interfere with the production of
    proteins needed to form healthy muscle.There
    are many different kinds of muscular dystrophy.
    Symptoms of the most common variety initiate in
    childhood, mainly in boys. Other types don't
    surface until adulthood.There can be a loss in
    the ability of walking in the people who are
    suffering from muscular dystrophy. Few may have
    trouble in breathing or swallowing.Still, there
    is no cure available for muscular dystrophy. But
    medications and therapy can help in managing
    symptoms and slow the course of the disease.

Causes of Muscular Dystrophy
  • There are some certain genes which are involved
    in making proteins that further save muscle
    fibers from getting damage. If one of these genes
    gets defected, muscular dystrophy occurs.Each
    form of muscular dystrophy is caused by a genetic
    mutation specific to that type of the disease.
    Many of these mutations are inherited. But some
    occur spontaneously in the mother's egg or the
    developing embryo and can be passed on to the
    next generation.

Risk Factors
  • Muscular dystrophy happens in both sexes and in
    all ages and races. However, the most common
    variety, Duchenne, generally occurs in young
    boys. People who are having a family history of
    muscular dystrophy are at higher risk of
    developing the disease or passing it on to their
    children.

Complications
  • The complications of progressive muscle weakness
    include
  • Unable to walk - Some people with muscular
    dystrophy eventually need to use a wheelchair.
  • Contractures - Contractures can further limit
    mobility.
  • Breathing problems - Gradual weakness can affect
    the muscles associated with breathing. People
    with muscular dystrophy may eventually need to
    use a breathing assistance device (ventilator),
    initially at night but possibly also in the day.
  • Problem with spine The weak muscles will be
    unable to hold the spine straight.
  • Problems associated with heart - Muscular
    dystrophy may lower the efficiency of the heart
    muscle.
  • Problem associated with Swallowing - If the
    muscles that are involved with swallowing gets
    affected, nutritional problems and aspiration
    pneumonia will be developed. Feeding tubes may be
    an option.
