2 type 1 SMA babies show signs of restored motor neuron connections

Treatment with Spinraza (nusinersen) and Zolgensma (onasemnogene abeparvovec) led to increases in the electrical activity of motor neurons — the specialized nerve cells that control voluntary movement — for two young children with type 1 spinal muscular atrophy (SMA), according to a new report. Findings from tests…

Study: Kidney stones may be more common in SMA type 1 children

Children with spinal muscular atrophy (SMA) type 1 may be at an increased risk of developing kidney stones, suggesting the condition may be more common than previously thought, according to a small study in Turkey. It’s possible that nephrolithiasis — the medical term for kidney stones — has been…

AI-based tool to assess muscles, nerves shows promise as biomarker

A newer assessment method known as dEMB, for decomposition electromyography — which uses artificial intelligence (AI) tools to measure nerve and muscle function — strongly correlated with measures of physical function and was able to distinguish people with spinal muscular atrophy (SMA) who were able to walk from those…

Bone health is impaired in SMA children, but treatment may help

Children with spinal muscular atrophy (SMA) generally have poor bone health, including low bone mineral density and reduced bone formation and remodeling, a study indicates. The effect on bone health is more pronounced in children with worse motor function, but as treatment with Spinraza (nusinersen) improved motor function…

Breathing problems during sleep often mistaken for apnea in SMA

People with spinal muscular atrophy (SMA) may experience bouts of breathlessness during sleep that can look at first glance like obstructive sleep apnea (OSA), but is not associated with a blockage of the airways that defines the sleep disorder, a case study highlights. Distinguishing between true sleep apnea and…
