What is the life expectancy of a child with SMA Type 1?

The life expectancy of patients with spinal muscular atrophy (SMA) type I is generally considered to be less than 2 years. Recently, with the introduction of proactive treatments, a longer survival and an improved survival rate have been reported.

What is SMA type 1 symptoms in babies?

Infants with type 1 SMA have difficulty swallowing and sucking. They don’t meet typical milestones like holding up their heads or sitting. As muscles continue to weaken, children become more prone to respiratory infections and collapsed lungs (pneumothorax).

However, people who’ve been treated with new SMA drugs have seen promising improvements in their quality of life — and life expectancy. Children with other types of SMA can survive long into adulthood and live healthy, fulfilling lives.
