What Are the Key Differences Between SMA Type 3 and Type 4?
SMA Type 3 and SMA Type 4 are often considered later-onset forms of Spinal Muscular Atrophy, but they are not the same. SMA types have historically been described by the age symptoms begin and the highest physical milestone a person reaches, such as sitting, standing, or walking.
SMA Type 3, sometimes called Kugelberg-Welander disease or juvenile SMA, usually begins after 18 months of age and may appear in childhood or adolescence. Many individuals with SMA Type 3 are able to stand or walk independently at some point, but they may experience progressive weakness, difficulty climbing stairs, trouble rising from a seated position, fatigue, balance challenges, and possible loss of walking ability over time. SMA Type 3 can severely affect the thigh muscles, especially the quadriceps, leading to unsteady walking and difficulty with stairs or standing from sitting. SMA Type 4, on the other hand, is a rarer adult-onset form that often begins in adulthood and is typically milder, with slower progression and weakness that may affect walking, endurance, and daily movement.
