An international study initiated by Washington University has found that giving monthly blood transfusions to children with sickle cell anemia can significantly reduce their risk of what are known as “silent” strokes.

Unlike regular strokes, which have sudden, overt symptoms like difficulty speaking or numbness in an arm or leg, silent strokes can only be detected with an MRI scan, so they generally go unnoticed by parents and physicians.
