Spinal muscular atrophy
Overview
Spinal muscular atrophy (SMA) is an inherited condition which affects the nerves in the spinal cord that control movement. This causes muscles in the body to get weaker over time. SMA impacts the muscles used for moving, breathing, coughing and swallowing. Babies with the most severe type of SMA have weak muscles from birth and have, historically, passed away in childhood. However, new treatments may allow children with severe SMA to achieve milestones previously thought impossible, such as sitting, crawling, and walking. These treatments may also improve life expectancy and quality of life.
