Oxygen therapy shows promise for rare childhood movement attacks

This study tested whether breathing high-flow oxygen can quickly stop dystonic and plegic attacks in children with alternating hemiplegia of childhood (AHC), a rare genetic disorder causing temporary paralysis and muscle spasms. Twenty-four participants used oxygen or a placebo during attacks over five weeks. The goal was to see if more attacks stopped within 30 minutes with oxygen, offering a potential fast-acting treatment for these disabling episodes.
