Muscular Dystrophy
What is muscular dystrophy?
Muscular dystrophy is a serious inherited
degenerative condition, which causes the muscles to weaken and deteriorate
over time. There are many diverse types of muscular dystrophy and each
one has slightly different symptoms and characteristics. Muscular dystrophy
is more common than people may think; the most common form, Duchenne
muscular dystrophy, affects around 1 in 3,500 boys.
Types of muscular dystrophy
There are more than thirty different
types of muscular dystrophy; some of the more widespread forms are outlined
below:
- Duchenne MD: this is the
most common form of muscular dystrophy; it is also the most severe form
of the condition. Duchenne MD only affects boys; most boys are diagnosed
with the condition at the age of three or four. Duchenne MD usually
affects the muscles in the legs first and then moves to other muscle
groups.
- Myotonic MD: this is the
most common form of muscular dystrophy amongst adults. This form can
affect both sexes and it usually affects the smaller muscle groups.
- Becker muscular dystrophy:
this is similar to Duchenne MD but it is often milder and it doesn’t
progresses as rapidly. Most people are diagnosed after the age of ten.
- Limb-girdle MD: there are
many different forms of limb-girdle muscular dystrophy; this type of
MD can affect both sexes and it usually develops in the early part of
adult life. This condition generally develops in the muscles around
the shoulder as well as the hip but it can spread to other parts of
the body very quickly.
- Oculopharyngeal MD: this
form of muscular dystrophy usually develops between the ages of 50 and
60; it affects the muscles around the eye and the throat.
- Facioscapulohumeral MD:
this form of muscular dystrophy usually develops after the age of ten;
it tends to progress slowly and affects the muscles in the face, the
upper arm and the shoulders.
