Hierarchy  - English - French - German - Spanish - Portuguese - Italian - Dutch    Muscular Atrophy, Spinal Definition: A group of disorders marked by progressive degeneration of motor neurons in the spinal cord resulting in weakness and muscular atrophy, usually without evidence of injury to the corticospinal tracts. Diseases in this category include Werdnig-Hoffmann disease and later onset SPINAL MUSCULAR ATROPHIES OF CHILDHOOD, most of which are hereditary.

More information from the Genetics Home Reference Website What is spinal muscular atrophy? Spinal muscular atrophy is a disorder that affects the control of muscle movement. It is caused by a loss of specialized nerve cells, called motor neurons, in the spinal cord and the part of the brain that is connected to the spinal cord (the brainstem). The loss of motor neurons leads to weakness and shrinkage (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. Spinal muscular atrophy is divide ... How common is spinal muscular atrophy? Spinal muscular atrophy affects 1 in 6,000 to 1 in 10,000 people.
