Depends on type: Prognosis is poor for infants with SMA type i. Most die w/in the 1st 2 years. Sma type ii: prognosis for life expectancy or independent standing/walking roughly correlates with how old they are when they first begin to experience sx's - older children tend to have less severe symptoms life expectancy is reduced with survivers in young adulthood. Type iii prone to resp. Infections-nml life span.

Years: Although we used to see these children pass away within the first 1-2 years of life, now with good handwashing, treatment of infection, and machine ventilation, lifespan has increased.

How much time can a child live with type one SMA (spinal muscular atrophy)?

Not too long: Most children with type one SMA unfortunately develop severe muscle weakness that reflects on their ability to breath effectively and would pass away within few months of life unless they get on long term mechanical ventilation. Such a treatment is generally not recommended as it would prolong suffering with no improvement in the muscle function.
