Summary

This trial will help researchers learn more about how changes in blood flow and metabolism influence brain development.

Who is the study for?
This trial is for healthy individuals or those with sickle cell anemia, aged 3-50, who can have an MRI without sedation. It's not for pregnant women, people on certain blood flow medications, those with severe psychiatric conditions as determined by the study leader, a history of stroke or epilepsy.
What is being tested?
The study tests how well brain blood vessels can handle increased demand by using carbon dioxide to dilate them during MRI scans. This helps understand oxygen metabolism and its impact on brain development and potential silent strokes in children.
What are the potential side effects?
Potential side effects may include discomfort from wearing a special mask to control carbon dioxide intake and reactions related to the MRI procedure or neuropsychological assessments. Blood draws might cause minor pain or bruising.
