9 Most Common Types of Muscular Dystrophy

1. 9 Most Common Types of MUSCULAR DYSTROPHY A category of genetic disorders known as muscular dystrophy is defined by the weakness and withering away of muscle tissue, with or without the destruction of nerve tissue. There are nine different forms of muscular dystrophy, and each one causes a progressive loss of strength, increased disability, and potential deformities. Duchenne muscular dystrophy (DMD) is the most widely recognized type of muscular dystrophy, followed by Becker muscular dystrophy (BMD). There are 9 distinct forms of muscular dystrophy, which are listed below. Each variety has a different range of impaired muscles, onset age, and rate of progression. Some varieties are given the names of the affected muscles, such as Type of MD Onset Age Symptoms & Life Expectancy The pelvis, upper arms, and upper legs are affected, and gradually, all voluntary muscles are affected. Survival above the age of 20 is uncommon. Duchenne 2 - 6 years Observed only in boys. Women are far less likely to be affected than men, and their prognosis is better.

2. Remarkably similar symptoms to Duchenne muscular dystrophy but less severe. Becker 12 - 18 years Develops more slowly; lives until middle age. The disease is nearly always only present in males, similar to Duchenne. Generalized muscle weakness and potential joint abnormalities. Congenital Birth The disease advances slowly and shorten life expectancy. Symptoms include weakening of all muscle groups along with delayed relaxation of muscles following contraction Myotonic 20 - 40 years Gradual progression, sometimes lasting 50 to 60 years. The shoulder, upper arm, and shin muscles might become weak and waste away; joint abnormalities are frequent. Emery-Dreifuss Childhood to teens The condition progresses slowly; and sudden cardiac death can happen. Facial muscle weakness and partial atrophy of the shoulders and upper arms are symptoms. Facioscapulo- Childhood to humeral early adulthood The condition progresses slowly with intervals of rapid degeneration. Life expectancy may be many decades after commencement. The shoulder girdle and pelvic girdle are the first areas to experience weakening and waste. Limb-Girdle Late childhood to middle age The disease progresses slowly. Cardiovascular problems are typically what cause death.

3. The symptoms weaken the neck muscles, which eventually results in difficulty swallowing and emaciation from a lack of food. Oculopharyngeal 40 - 70 years The process is very slow. Muscle atrophy and weakness in the hands, forearms, and lower legs are common symptoms. Distal 40 - 60 years The condition sometimes results in total disability.
