Most of this disease has poor prognosis. The prognosis of SMA- type I was the worst, and about 95% died in the 18 months after birth. SMA- type II has a relatively benign course of disease, most of which can live to childhood and live to adulthood individually. The prognosis of SMA- type III is good, especially in women. Life usually reaches adulthood, and many patients have normal life expectancy. More severe cases are often male patients. The prognosis of SMA- IV is relatively good, and the ability to walk often can be maintained for a lifetime. The natural course of chronic asymmetric SMA is longer, even more than 30 years.
