Preventive measures that can be taken to avoid sustaining a<unk>  are the same as for stroke. Smoking cessation is the most immediate step that can be taken, with the effective management of hypertension the major medically treatable factor. Sickle cell anemia Transfusion therapy lowers the risk for a new<unk>  in children who have both abnormal cerebral artery blood flow velocity, as detected by transcranial Doppler, and previous<unk>  infarct, even when the initial MRI showed no abnormality. A finding of elevated TCD ultrasonographic velocity warrants MRI of the brain, as those with both abnormalities who are not provided transfusion therapy are at higher risk for developing a new<unk>  infarct or stroke than are those whose initial MRI showed no abnormality.
