NCT ID NCT04406818
First seen Jun 25, 2026 · Last updated Jun 26, 2026 · Updated 1 time
Summary
This study looks at how blood flow and metabolism affect brain development in children with sickle cell anemia. Researchers will use MRI scans and a special mask to have participants breathe carbon dioxide, which helps measure how well brain blood vessels expand. The goal is to understand why some children develop silent strokes or slower brain growth, which could lead to better prevention strategies.
