The loss of motor neurons leads to weakness and wasting (atrophy) of muscles used for activities such as crawling, walking, sitting up, and controlling head movement. In severe cases of spinal muscular atrophy, the muscles used for breathing and swallowing are affected.
The muscular dystrophies are a group of genetic diseases that affect skeletal muscles and often also heart muscle. The symptoms include muscle weakness and progressive muscle wasting. Duchenne muscular dystrophy (DMD) is the most common and a very severe form of the disease.It is caused by a genetic fault which prevents the production of a protein called dystrophin. Without dystrophin, muscles are fragile and are easily damaged.uchenne muscular dystrophy (DMD) is the most common and a very severe form of the disease.
