Brain speed test could transform sickle cell care
NCT ID NCT07168447
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study examines how regular blood transfusions (exchange transfusions) affect thinking speed in adults with severe sickle cell disease. Researchers will test 85 participants remotely using a simple symbol-matching task and other cognitive assessments at different points in their transfusion cycle. The goal is to see if processing speed can be a reliable marker for monitoring brain health in this condition.
What this could mean

What this could lead to
If successful, this could help doctors use a simple thinking-speed test to monitor brain health in sickle cell patients and guide future treatments.
What could go wrong
This is an early observational study, not a treatment trial. It may not find clear links, and results might not apply to all patients.
