6 types of muscular dystrophy
Muscular dystrophy is a disease which causes progressive weakness and loss of muscle mass. It occurs due to the interference of abnormal or mutated genes with the production of proteins needed to form a healthy muscle. There is no specific cause of suffering from muscular dystrophy as it affects the person at a genetic level. The primary symptom of muscular dystrophy is progressive muscle weakness. Specific signs and symptoms of the disorder begin at different ages and in different muscle groups. Following are some types of muscular dystrophy based on different ages, symptoms, and muscle group: Duchenne muscular dystrophy (DMD) It is the most common and the most severe form of muscular dystrophy. Duchene muscular dystrophy (DMD) accounts for a total of 50 percent of total cases of muscular dystrophy. It is caused due to a deficiency of dystrophin, which is a protein that helps in strengthening muscle fibers, thereby, protecting them from injury. The DMD symptoms include unusually fat calf muscles due to fat accumulation, waddling when walking, and facing difficulties to rise from a sitting or a lying position. DMD usually develops in boys aged between three and five and progresses rapidly. Becker muscular dystrophy (BMD) Having similar causes as DMD, Becker muscular dystrophy (BMD) is also caused due to deficiency of dystrophin.
