Study Summary

Sickle cell disease is an inherited blood disorder that affects red blood cells (RBCs). People with sickle cell disease frequently experience anemia, or a low number of RBCs. RBCs are responsible for carrying oxygen to the brain and other body tissues that need oxygen to function properly. The purpose of this study is to determine what changes, which were possibly caused by anemia, exist in the brains of individuals with sickle cell disease.
