Adult spinal muscular atrophy is a genetic disorder. Atrophy refers to a gradual weakening of the muscles necessary for movement. In SMA, this occurs around the spine as lost nerve cells leads to the connection between the spinal cord and brain to degrade. Lost nerve cells also mean that symptoms become more severe with age. Spinal muscular atrophy (SMA) is a group of genetic diseases that cause weakness and wasting in the voluntary muscles of infants and children and, more rarely, in adults. It is a one of the most common genetic conditions affecting children. It is estimated that one in every 6, to 10, babies worldwide is born with SMA.

The patient's condition tends to deteriorate over time, depending on the severity of the symptoms. Jan 26, · Spinal Muscular Atrophy Adult Type is a condition that affects the nerve cells (motor neurons) in your spinal cord. Onset of this condition is usually after 30 years of age.
