Spinal Muscular Atrophy

Spinal muscular atrophy is a disease of genetic origin that affects the neurons responsible for transmitting movement commands to the muscles. When that communication fails, the muscles weaken and progressively lose volume.

Common manifestations:

• Muscle weakness, especially in the trunk and limbs
• Difficulty holding posture, moving or, in some cases, breathing and swallowing
• Progressive loss of strength

When to seek care? When weakness or delay in motor development is observed, especially in babies and small children.

Which specialist treats it? The approach is usually multidisciplinary, with neurology or pediatric neurology, pediatrics, and physical therapy working together. If you notice muscle weakness that progresses or affects development, it is important to go for a professional evaluation.
