We told you that we both
have muscular dystrophy. I have Limb-Girdle MD (LGMD) and Larry
has Childhood Congenital Myotonic MD. Beside the description of
life having MD, which I did it in
Growing Up section, we want to let you know some general
things about what MD means, how many kind of MD exist, how they
affect the muscles, when it starts, how does it progress, what
can be done for a slower progression of it... Also I will post
for you some links to the websites which you can visit for more
information.
Muscular dystrophy (MD) is a group of disorders
characterized by progressive muscle weakness and loss of muscle tissue MD
refers to a group of genetic diseases
characterized by progressive weakness and degeneration of the
skeletal or voluntary muscles which control movement. The
muscles of the heart and some other involuntary muscles are also
affected in some forms of MD, and a few forms involve other
organs as well. The major forms of MD include Myotonic, Duchenne,
Becker, Limb-Girdle, Facio-Scapulo-Humeral (FSH), Congenital, Oculo-Pharyngeal,
Distal and Emery-Dreifuss. Duchenne is the most
common form of MD affecting children, and myotonic MD is the
most common form affecting adults. MD 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.
Aspects of several forms of muscular dystrophy share symptoms
with other disorders of muscle, including disuse and age-related
atrophy, which affect even larger population groups.
Till now there is no
specific treatment for any of the forms of MD. Some
opportunities to improve treatment exist in the areas of vector
development for gene-based treatments, cell-based treatments
registering improvement but they can't say if this improvements
are stabile in time. Physical therapy (PT) to prevent
contractures (a condition in which shortened muscles around
joints cause abnormal and sometimes painful positioning of the
joints), the adaptive technologies, orthoses (orthopedic appliances used for support),
corrective orthopedic surgery may be needed to improve the
quality of life in some cases. The cardiac problems may require
a pacemaker. The myotonia (delayed relaxation of a muscle after
a strong contraction) occurring in myotonic MD may be treated
with medications.
The prognosis of MD
varies according to the type of MD 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.
There are many programs
of research on MD. The goals of these studies are to increase
understanding of MD and its causes, develop better therapies,
and, finally, find ways to prevent and cure the disorder.
