The research involved 3,300 children with sickle cell anemia in 2019. It found 47% of children aged 2–9 years and 38% of those aged 10–16 received an ultrasound scan to check blood flow and assess their risk for stroke. Blood transfusions can help those at high risk.
The study also found 38% of the younger kids and 53% of the older ones used hydroxyurea, a drug that can reduce periods of severe pain and other complications.
