Symptoms of Spinal Muscular Atrophy vary by kind. In general, patients with Spinal Muscular Atrophy lose muscle control, movement, and strength as the disease progresses. Muscle loss worsens as you become older. The muscles closest to the torso and neck are the most severely affected by the condition. Some Spinal Muscular Atrophy patients never walk, sit, or stand. Others lose their capacity to perform these tasks over time. #spinalmuscularatrophy
