Could steroids help kids recover from stroke?
NCT ID NCT04873583
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests whether adding high-dose steroids to standard aspirin treatment helps children recover better from a stroke caused by inflamed brain arteries. About 70 children aged 6 months to 18 years will be randomly assigned to receive either steroids plus aspirin or aspirin alone. The goal is to see if steroids reduce artery damage and improve long-term function.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Methylprednisolone and Prednisolone (steroids)
- What this could lead to
- If it works, this could point toward a treatment that reduces brain damage and prevents repeat strokes in children with inflammatory arteriopathy.
- What could go wrong
- This is a relatively small Phase 3 trial (70 children), and steroids have known side effects like immune suppression and mood changes. The benefit over aspirin alone is not yet proven.
