Spinal muscular atrophy or SMA is a genetic disease. It causes muscles to become emaciated and weak over time. Most cases can be diagnosed in young children or babies. Currently, there is still no cure for the condition. However, many treatments can help improve the outlook and quality of life. Take a moment to learn more about the common symptoms of spinal muscular atrophy.
Common Symptoms
The main symptom of spinal muscular atrophy is reduced muscle strength. All forms might cause weakness and deterioration of the proximal skeletal muscles located in the torso, thighs, and upper arms. They would become worse gradually and make it challenging to use the arms, hold up the neck, seat, or stand normally. Another possible sign is diminished muscle tone. This leads to limp and loose legs or arms. The affected muscles can have a thin and puffy look. In the long run, the condition would result in muscle contractures or a change in posture. When the condition affects respiratory muscles, difficulty breathing, and other respiratory issues can happen. [1]
