Lung Ultrasound Reliable Option to Chest X-rays for Monitoring Children

Lung ultrasound is a safe and reliable bedside tool to detect atelectasis (partial lung collapse) early in children with neuromuscular diseases, including spinal muscular atrophy (SMA), a study suggests. This radiation-free method could be used to monitor lung health...

How Salbutamol May Help Patients with Spinal Muscular Atrophy: New Insights

The vast majority of spinal muscular atrophy (SMA) cases are caused by a mutation in the survival motor neuron 1 (SMN1) gene, which leads to abnormally low levels of SMN1 gene products.1 Many attempts at therapy have focused on how to increase SMN levels in SMA...

Patient and Parent Perspectives on the Use of Nusinersen for Spinal Muscular Atrophy

At the end of 2016, the U.S. Food and Drug Administration (FDA) approved nusinersen for the treatment of spinal muscular atrophy (SMA).1 Because of the high threshold for FDA approval, an abundance of data on nusinersen and its physiological effects on SMA patients...
