Treat early or wait? Experts ponder best way to manage milder forms of spinal muscular atrophy

The advent of therapeutic interventions for spinal muscular atrophy (SMA) has increased the importance of presymptomatic diagnosis and treatment. When to start treatment in children with less severe disease remains controversial. Now, in a report published in the Journal of Neuromuscular Diseases, German researchers argue for an earlier start of treatment to prevent permanent nerve damage, challenging recommendations originally proposed by a group of American experts that suggests a strict follow-up strategy for children expected to have less severe disease.
