Muscular dystrophy is also referred to as (MD). The term muscular dystrophy refers to a group of genetic, hereditary muscle diseases. These diseases cause progressive muscle weakness in the muscles that enable your body to move.
If you have muscular dystrophy, you have incorrect or missing information in your genes. Because of this, the proteins that are needed for healthy muscles are not made. Muscular dystrophy is a disease that you are born with (congenital). You cannot catch it from someone else.
Muscular dystrophy causes your muscles to weaken over time. You may gradually lose your ability to do things that are taken for granted by most people. These are things like sitting up or walking. The problems caused by muscular dystrophy can start anywhere from infancy to adulthood.
There are several different kinds of muscular dystrophy that affect different muscle groups in different ways. Landouzy-Dejerine dystrophy is one of the forms of this disease.
Landouzy-Dejerine dystrophy is evidenced by progressive muscle weakness and wasting (loss of muscle tissue). This usually originates in childhood or by the age of 20. However, these signs and symptoms may not be revealed until later in life or not at all. The signs and symptoms of Landouzy-Dejerine dystrophy usually progress very slowly.
Not much was known about what causes any form of muscular dystrophy until the 1980s. Then, researchers discovered that it is caused by a defective (faulty) gene. There is an insufficient amount of dystrophin that is produced because of this faulty gene. Dystrophin is a protein that helps keep your muscle cells intact.
When it starts, Landouzy-Dejerine dystrophy affects the muscles around your lower legs, upper arms, shoulders, mouth and eyes. Later, you may experience weakness in your abdominal muscles and sometimes your hip muscles.
There are other signs and symptoms that you may have with Landouzy-Dejerine dystrophy. Some of these are:
- Shoulder deformities
- Problems with pronouncing words
- Angry or depressed facial expression
- An inability to whistle
- Decreased facial expression
- Abnormal heart rhythms
- Difficulty walking
- Drooping of your eyelids
- Hearing loss
- Difficulty raising your arms.
You or a loved one may be afflicted with Landouzy-Dejerine dystrophy. Landouzy-Dejerine dystrophy and/or complications that have been caused by it or other disorders that you have besides this disease may have led to the disability of you or your loved one and be what is keeping you from being able to work.
