The Main Types of Spinal Muscle Atrophy (SMA)
As of 2018, there are more than 25,000 people in the U.S. That suffer from spinal muscular atrophy (SMA). Interestingly, no two people who have been diagnosed with SMA have the same symptoms because there are different types of spinal muscular atrophy. There are four main types of SMA and other lesser developed spinal muscular atrophy illnesses: 1. SMA Type I This is the more severe and common type of SMA called Werdnig-Hoffmann Disease. Type I is aptly diagnosed when it strikes an infant during their first six months. The Werdnig-Hoffmann Disease leaves babies with the inability to move their muscles. They also will be unable to swallow, to hold their heads up, and labored breathing. Unfortunately, SMA is a disease that progresses quickly forcing the medical staff to insert feeding tubes and tubes to help with breathing. SMA has a fatal outcome for babies. 2. SMA Type II Following the more severe SMA is Type II. SMA Type II strikes between the ages of 7 and 18 months. Type II SMA also progresses quickly. This disease causes a child’s legs and arms to become weakened robbing them of the ability to move their arms or legs. Breathing problems also affect children with Type II but with medical assistance, children can live with this disease into adulthood.
