Summary

This trial is looking at how blood flow and metabolism affects brain development in early life. SCA participants and healthy controls will have their blood flow and metabolism examined using MRI, and will also undergo cognitive assessments and brief questionnaires.

Who is the study for?
This trial is for children and young adults aged 4-21 with sickle cell anemia (SCA) or healthy individuals without significant psychiatric history, epilepsy, stroke, or cerebrovascular disease. Participants must be able to have an MRI scan without sedation and not be pregnant.
What is being tested?
The study tests how breathing in carbon dioxide affects blood flow in the brain using MRI scans. It aims to understand blood vessel function related to oxygen delivery during normal activities and stress in SCA patients compared to healthy controls.
What are the potential side effects?
Breathing in controlled amounts of carbon dioxide may cause temporary discomfort such as a feeling of breathlessness or lightheadedness due to dilation of blood vessels but is generally well-tolerated.
