What is Spinal Muscular Atrophy? (Definition)
Spinal muscular atrophy is a disorder of genetic origins which affects the ability to control muscle movement. The condition is caused by a loss of motor neurons in the spinal cord and the brainstem (part of the brain that is connected to the spinal cord). The loss of motor neurons leads to weakness and wasting (atrophy) of muscles used for various normal 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. There are many types of spinal muscular atrophy distinguished by the pattern of features, severity of muscle weakness, and age when the muscle problems begin.
