SMA (Spinal Muscular Atrophy) is a muscle disease that restricts mobility by affecting the anterior horn motor nerve cells in the spinal cord.
The incidence is 1 / 10,000 across the world and 1 / 6,000 in Turkey. Due to the degeneration seen in the anterior horn cells, protein necessary for the nerves function that control our muscles cannot be produced.
Weakness and loss (atrophy) are seen in voluntary muscles.
Failure of nerve cells to function causes weakness and often fatal muscle weakness. Involuntary muscles are not affected by this disease.
The vision and hearing senses of individuals with SMA are not affected by the disease. Intelligence is normal or above normal.
